Description

Correspondence relationship sending method and device, storage medium and electronic device

This disclosure claims the priority of the Chinese patent application filed with the China Patent Office on December 26, 2023, with application number 202311825689.7 and invention name “Method and device for sending corresponding relationships, storage medium and electronic device”, the entire content of which is incorporated by reference in this disclosure.

Technical Field

The embodiments of the present disclosure relate to the field of communications, and in particular, to a method and device for sending a corresponding relationship, a storage medium, and an electronic device.

Background Art

With the advent of 5G and the cloud era, IP networks have entered the industrial Internet stage. The most obvious characteristics of network requirements for applications in this stage are massive connections, quality assurance, and customizable quality. Currently, applications with differentiated demand characteristics are emerging in an endless stream, such as mobile Internet application scenarios for enhanced bandwidth and device interconnection application scenarios for massive IoT.

Based on the end-to-end layered design principles and concepts of the Internet, and facing the differentiated needs of segmentation, the past completely decoupled approach of network and application is no longer suitable, and the demand for network-aware services is becoming increasingly strong. Traditional network-aware services are mainly implemented through two technologies: service identification and service marking. The former uses five-tuple and deep packet inspection (DPI) to identify the application attribution of traffic, and the latter uses the QoS priority field to simply classify the traffic to mark the service needs of the traffic. The two are combined to provide different services for different applications. In addition, the quality detection based on the closed-loop adjustment of the connection service provided by the network is mainly based on telecom-grade OAM, which cannot truly feedback the service quality. The new flow detection technology truly feedbacks the quality of the service flow, but the flow detection is oriented to fine-grained specific flows and cannot feedback the quality of all flows in the connection pipeline, thus failing to form a service level agreement (SLA) guarantee for efficient service quality.

With regard to related technologies, the network is unable to manage and provide massive differentiated connection services, and cannot meet the problem of arbitrary modification and adjustment of service quality requirements. No effective solution has been proposed so far.

Therefore, it is necessary to improve the related technology to overcome the above-mentioned defects in the related technology.

4. Service-aware gateway: The existing network is connected to the routers of service users and providers to incrementally upgrade business awareness and differentiated service capabilities. It only involves modifications to the management and data planes, and does not modify the control plane and intermediate node forwarding planes, which can achieve smooth evolution of the existing network.

In this embodiment, a method for sending a corresponding relationship running on the above-mentioned computer terminal is provided. FIG. 3 is a flow chart of the method for sending a corresponding relationship according to an embodiment of the present disclosure. As shown in FIG. 3 , the process includes the following steps:

Step S302: receiving a registration request sent by the management system of the server, wherein the registration request is used to request registration The connection service, the registration request includes: feature information and service quality requirements of the connection service, and the server is the provider of the connection service;

The above-mentioned characteristic information must include at least one of the following: the destination Internet address of the server, the destination port of the server; and the characteristic information may also include at least one of the following: the abstract type of the business application corresponding to the connection service, and user permissions.

Step S304, generating a service identifier according to the characteristic information, and generating a traffic configuration strategy according to the service quality requirement and an Internet address, wherein the Internet address is an address of a service-aware gateway to which the server and/or terminal is connected, and the terminal is a user of the connection service;

Step S306: Send the correspondence between the service identifier and the traffic configuration policy to the service-aware gateway.

Through the present disclosure, a registration request sent by a management system of a server is received, wherein the registration request is used to request registration of a connection service, and the registration request includes: characteristic information and service quality requirements of the connection service, and the server is the provider of the connection service; a service identifier is generated according to the characteristic information, and a traffic configuration policy is generated according to the service quality requirements and an Internet address, wherein the Internet address is the address of a service-aware gateway to which the server and/or terminal is connected, and the terminal is the user of the connection service; and the correspondence between the service identifier and the traffic configuration policy is sent to the service-aware gateway. That is, in the embodiments of the present disclosure, a service identifier of the connection service is generated through the characteristic information of the connection service, and a traffic configuration policy is generated according to the service quality requirements of the connection service and the Internet address of the service-aware gateway connected by the provider and/or user of the connection service, so as to realize open characteristic management of the connection service and issuance of a unique corresponding identifier. Moreover, since the service identifier is only associated with the characteristic information of the connection service, the service quality requirements can be modified at will, and then the traffic configuration policy can be modified according to the service quality requirements. Therefore, the problem that the network cannot manage and provide a large number of differentiated connection services and cannot meet the arbitrary modification and adjustment of service quality requirements can be solved, and the effect of fine-grained programmable definition of services and SLA service guarantee is realized.

Optionally, the above-mentioned step S304 can be implemented by the following steps: when the service quality requirement includes an uplink service quality requirement and a downlink service quality requirement, a first traffic configuration strategy is generated according to the downlink service quality requirement and a first Internet address, and a second traffic configuration strategy is generated according to the uplink service quality requirement and the second Internet address, wherein the traffic configuration strategy includes: the first traffic configuration strategy and the second traffic configuration strategy, the Internet address includes: the first Internet address and the second Internet address, the first Internet address is the address of the first service-aware gateway to which the terminal is connected, and the second Internet address is the address of the second service-aware gateway to which the server is connected.

In the embodiment of the present disclosure, the service quality requirements carried in the registration request may include: an uplink service quality requirement, may also include: a downlink service quality requirement, and may also include: an uplink service quality requirement and a downlink service quality requirement;

When the service quality requirements include: uplink service quality requirements and downlink service quality requirements, a first traffic configuration strategy is generated based on the downlink service quality requirements and the address of a first service-aware gateway connected to a terminal of the downlink network, and a second traffic configuration strategy is generated based on the uplink service quality requirements and the address of a second service-aware gateway connected to a server end of the uplink network.

It can be seen from the above embodiments that one registration in the present disclosure allows for simultaneous expression of uplink and downlink service quality requirements, and supports an optional downlink service quality requirement mode.

Optionally, when generating a first traffic configuration policy and a second traffic configuration policy, the correspondence between the first service identifier and the first traffic configuration policy is sent to the second service-aware gateway, and the correspondence between the first service identifier and the second traffic configuration policy is sent to the first service-aware gateway.

In the disclosed embodiment, the traffic configuration policy corresponding to the uplink service quality requirement is sent to the service-aware gateway connected to the terminal, and the traffic configuration policy corresponding to the downlink service quality requirement is sent to the service-aware gateway connected to the server.

After sending the traffic configuration policy to the corresponding service-aware gateway, the service-aware gateway triggers the generation of a service path corresponding to the traffic configuration policy, which is used for subsequent reception of messages carrying the SAN-ID identifier and selection of the corresponding service path based on the SAN-ID identifier.

Furthermore, the present disclosure also provides a method for a terminal or a customer premises equipment gateway (Customer Premises Equipment, referred to as CPE) to subscribe to a connection service, that is, a method for a terminal or CPE to obtain a service identifier SAN-ID identifier, specifically:

1. The terminal APP obtains the corresponding SAN-ID according to the characteristic information of the connection service to be accessed. The service identifier can be obtained through manual configuration, the return message after the APP initiates the connection account authentication (service provider solution management and authentication platform), DNS extension carrying, etc.

2. The CPE belongs to the network domain, and the management and control system directly issues the SAN-ID and corresponding service characteristics. The ACL or DPI identifies the service characteristics and directly adds the SAN-ID to the service flow based on the corresponding relationship.

Optionally, before generating a traffic configuration strategy based on the service quality requirements and the Internet address, the above-mentioned Internet address is also obtained. The embodiment of the present disclosure provides two implementation methods: one is a static acquisition method, and the other is a dynamic acquisition method. The static acquisition method is: obtaining the Internet address according to the registration request, wherein the registration request includes: the Internet address; the dynamic acquisition method is: determining the destination Internet address of the connection service through flow learning; determining a routing table through the destination Internet address, and determining the Internet address in the routing table.

That is to say, the static acquisition method is to obtain the Internet address through the information carried in the received registration request; the dynamic acquisition method is to determine the corresponding Internet address through flow learning.

Furthermore, after sending the correspondence between the service identifier and the traffic configuration policy to the service-aware gateway, it also includes: determining whether the service quality requirement and/or the Internet address have been updated; when the service quality requirement and/or the Internet address have been updated, updating the traffic configuration policy corresponding to the connection service according to the updated service quality requirement and/or the updated Internet address; sending the correspondence between the service identifier and the updated traffic configuration policy to the service-aware gateway.

It can be understood that after the connection service is registered, it can support flexible adjustment based on the service quality requirements and the IP of the service-aware gateway of the server, and/or the IP of the service-aware gateway of the terminal without changing the characteristic information. During this process, the SAN-ID identifier remains unchanged, that is, when the service quality requirements and the IP of the service-aware gateway change, only the traffic configuration strategy is adjusted, and the terminal and the server are completely unaware of it, thus truly realizing flexible and programmable service capabilities.

Optionally, the adjustment of the above traffic configuration strategy is initiated by the server side or the control system automatically senses the demand change, specifically, at least one of the following:

Determining the quality of service requirement and/or whether the Internet address has been updated according to whether an update request sent by the management system is received;

The Internet address is monitored through flow learning to determine whether there is an update.

Since the Internet address in the embodiment of the present disclosure can be determined by the management and control system through flow learning, the management and control system can also automatically sense whether the Internet address has changed through flow learning.

In this embodiment, a method for receiving a corresponding relationship running on a service-aware gateway is also provided. FIG. 4 is a flow chart of a method for sending a corresponding relationship according to an embodiment of the present disclosure. As shown in FIG. 4 , the process includes the following steps:

Step S402: receiving the corresponding relationship between the service identifier and the traffic configuration strategy corresponding to the connection service sent by the management and control system. Among them, the management and control system is configured to receive a registration request sent by a management system corresponding to the server; generate a service identifier according to the characteristic information of the connection service, and generate a traffic configuration strategy according to the service quality requirements and Internet address of the connection service, wherein the registration request is used to request registration of the connection service, and the registration request includes: the characteristic information and service quality requirements of the connection service, the Internet address is the address of the service-aware gateway to which the server or terminal is connected, the terminal is the user of the connection service, and the server is the provider of the connection service.

Through the present disclosure, the corresponding relationship between the service identifier and the traffic configuration policy corresponding to the connection service sent by the management and control system is received, wherein the management and control system receives a registration request sent by the management system of the server, wherein the registration request is used to request registration of the connection service, and the registration request includes: the characteristic information and service quality requirements of the connection service, and the server is the provider of the connection service; the service identifier is generated according to the characteristic information, and the traffic configuration policy is generated according to the service quality requirements and the Internet address, wherein the Internet address is the address of the service-aware gateway connected to the server and/or the terminal, and the terminal is the user of the connection service; the corresponding relationship between the service identifier and the traffic configuration policy is sent to the service-aware gateway. That is, in the embodiment of the present disclosure, the service identifier of the connection service is generated by the characteristic information of the connection service, and the traffic configuration policy is generated according to the service quality requirements of the connection service and the Internet address of the service-aware gateway connected to the provider and/or user of the connection service, so as to realize the open characteristic management of the connection service and the issuance of the unique corresponding identifier, so as to solve the problem that the network cannot manage and provide a large number of differentiated connection services, and cannot meet the problem of arbitrary modification and adjustment of the service quality requirements, and realize the effect of fine-grained programmable definition of the business and SLA service guarantee.

Optionally, after receiving the correspondence between the service identifier corresponding to the connection service sent by the management and control system and the traffic configuration policy, the following steps need to be performed: generate a corresponding transmission path according to the traffic configuration policy; establish a correspondence between the service identifier and the transmission path; when receiving a data packet sent by the server or the terminal, determine the transmission path corresponding to the service identifier carried in the data packet according to the correspondence, and transmit the data packet according to the transmission path.

When the service-aware gateway receives the traffic configuration policy, the service-aware ingress gateway (that is, in the upstream network, the service-aware ingress gateway is the service-aware gateway connected to the terminal; in the downstream network, the service-aware ingress gateway is the service-aware gateway connected to the server) generates the SRv6 Policy transmission path corresponding to the SAN-ID identifier based on the traffic engineering algorithm, and then when the service message carrying the SAN-ID identifier enters the service-aware gateway, it directly identifies the SAN-ID identifier to implement differentiated traffic diversion services.

Optionally, after receiving the correspondence between the service identifier corresponding to the connection service sent by the management and control system and the traffic configuration policy, the following steps need to be performed: determine the corresponding flow detection method according to the service identifier; encapsulate the flow detection message based on the flow detection method, so as to determine the detection result of the transmission path through the flow detection message, wherein the detection result includes at least one of the following: transmission path portrait, nodes of the transmission path, and packet loss rate.

At the service-aware ingress gateway, the SRV6 POLICY corresponding to the mapped SAN-ID identifier directly enables the in-flow detection configuration based on the SAN-ID identifier, where the Endpoint of the POLICY represents the service-aware egress gateway; when the data plane receives a message carrying the SAN-ID identifier and matches the corresponding SRV6 POLICY, if the in-flow detection configuration is enabled, the in-flow detection message is encapsulated, and the corresponding in-flow detection technology can flexibly select any of INT, IOAM, IFA, and InbandOAM.

It should be noted that flow detection can support E2E mode for end-to-end performance detection, including packet loss, delay, and jitter detection. It can also support TRACE mode for business path profiling, node and link packet loss positioning, etc.

It should be noted that in the uplink network, the service-aware entry gateway is the service-aware gateway connected to the terminal, and the service-aware exit gateway is the service-aware gateway connected to the server; in the downlink network, the service-aware entry gateway is the service-aware gateway connected to the server, and the service-aware exit gateway is the service-aware gateway connected to the terminal.

Obviously, the embodiments described above are only some embodiments of the present disclosure, not all embodiments. In order to better understand the sending and receiving methods of the above correspondence, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present disclosure. Optionally:

To present the system operation mechanism and principle more clearly, as shown in Figure 2, from the perspective of the system management plane and data forwarding plane that meet business operations, the key processes are as follows:

1. Register the connection service.

The service provider's management system registers the connection service request to the intelligent management and control system based on the service type characteristics of the connection service, the network deployment location and the network quality requirements.

The steps to register a connection service are as follows:

Step 1: The service provider sends a registration request for registering a connection service to the intelligent management and control system, wherein, as shown in FIG2 , the registration elements carried in the registration request include at least: characteristic information of the connection service, SLA requirements (delay, bandwidth, jitter, packet loss) for accessing the uplink or downlink network when the service user initiates the connection service, and may also include: the IP address of the service-aware gateway connected to the service provider;

Step 2: The service management module in the intelligent management and control system generates a SAN-ID identifier (equivalent to the service identifier in the above embodiment) according to the characteristic information in the registration element, and issues the SAN-ID identifier to the service user. The service user can directly initiate a connection service through the SAN-ID identifier. The SAN-ID identifier is used to indicate when the connection service occurs, determine the corresponding connection requirements, and is used for the subsequent issuance of service gateway configuration policies and the service user to carry the identifier to enjoy the above connection service.

The registration instructions for the connection service are as follows:

1) Registration Instructions 1: As shown in FIG5 , FIG5 shows a registration example, including a registration type field and a feature information field, wherein the feature information must include at least one of the following: the destination Internet address of the server, the destination port of the server; and the feature information may also include at least one of the following: the abstract type of the business application corresponding to the connection service, and user permissions (such as game services and user VIP levels).

The SAN-ID identifier is generated by the above-mentioned characteristic information, so as to realize the generation of the SAN-ID identifier for fine-grained identification of connection services and expression of service quality requirements. The registration type field and characteristic information field in FIG5 are just an example for convenient management. As long as the connection description is provided with relevant characteristics, it belongs to the scope of the embodiments of the present disclosure.

2) Registration description 2: A registration request can carry both uplink and downlink SLA requirements, and supports an optional downlink SLA requirement mode.

3) Registration Instructions 3: After successfully registering for the connection service, the characteristic information of the connection service remains unchanged, and can be flexibly adjusted based on the SLA requirements of the connection service and the service-aware gateway IP of the service provider or the service-aware gateway IP of the service user. This adjustment can be initiated by the service provider platform to change the demand. During this process, the SAN-ID identifier remains unchanged, and step 2 is repeated. During the service demand implementation programming process, only the outflow configuration policy of the service-aware gateway is adjusted, and the terminal and service provider are completely unaware of it, truly realizing flexible and programmable service capabilities.

2. Send traffic configuration policy based on SAN-ID.

As shown in Figure 6, the intelligent management and control system generates a corresponding SAN-ID upstream diversion strategy and a corresponding SRv6 traffic configuration strategy based on the IP address and SLA parameter information of the service provider's service-aware gateway, and sends them to the service consumer's service-aware gateway. The service consumer's service-aware gateway triggers the generation of the corresponding service path. When the service consumer's service-aware gateway receives a message carrying the SAN-ID identifier, it selects the corresponding service path based on the SAN-ID identifier.

It should be noted that in the embodiments of the present disclosure, all parameters of the SLA (bandwidth, latency, jitter, and packet loss) can be used as constraint parameters of the metric type of the traffic engineering calculation configuration.

In the disclosed embodiment, the SAN-ID identifier can also be expanded to a diversion type. The SAN-ID identifier serves as a key diversion parameter for matching business messages. That is to say, when the message matches the traffic configuration policy MyPerFlow Policy, the forwarding diversion can be further matched and diverted directly according to the SAN-ID identifier. This is the key entry point to support differentiated network services.

In the disclosed embodiment, when the SLA return parameter is carried in the registration request, it indicates that the downlink service needs to meet the corresponding SLA requirement. According to the network planning and deployment, the intelligent management and control system uses the IP address of the service-aware gateway connected to the service user as the EGW-IP and the downlink SLA requirement as the traffic engineering calculation metric type constraint parameter to synchronously generate the SAN-ID identification diversion strategy and traffic configuration strategy (equivalent to the first traffic configuration strategy in the above embodiment).

Furthermore, the intelligent management and control system will generate relevant SAN-ID-based traffic diversion strategies and corresponding SRv6 traffic configuration strategies to the service-aware gateway connected to the service user. The corresponding service-aware gateway calculates the SRv6 policy path based on the traffic configuration strategy through the existing head node distributed computing or path computing element (PCE) centralized network controller and sends it to the data plane. The data plane is used to identify messages carrying SAN-ID identifiers and match them to provide differentiated connection services.

3. Subscription service.

The subscription service mode includes: the service user and the CPE. The subscription in the embodiment of the present disclosure can be understood as the service user and the CPE obtaining the SAN-ID identifier. The service identifier issuer can be an intelligent management and control system or a service provision solution management and authentication platform. The specific selection is based on the actual situation. The service user and the CPE initiate a service connection based on the SAN-ID identifier, which specifically includes two strategies:

1) The terminal APP obtains the corresponding SAN-ID according to the characteristic information of the service to be accessed. The service identifier can be obtained through manual configuration, the return message after the APP initiates the connection account authentication (service provider solution management and authentication platform), DNS extension carrying, etc.

2) The CPE gateway belongs to the network domain, and the intelligent management and control system directly issues the SAN-ID and corresponding service characteristics. The ACL or DPI identifies the service characteristics and directly adds the SAN-ID to the service flow based on the corresponding relationship.

4. Initiate connection service.

The service user obtains the SAN-ID identifier to carry for initiating a connection service, wherein the SAN-ID identifier can be encapsulated by terminal host encapsulation or CPE encapsulation, and the encapsulation formats are the same. The SAN-ID identifier is usually carried by an IPV6 extension header, specifically, it can be implemented by one or more of the system identifier (SID) in the Hop-by-Hop Options Header (HBH), the Destination Options Header (DoH), the Segment Routing Header (SRH), or the Tag-Length-Value (TLV).

5. Business awareness and differentiated services.

The service message carrying the SAN-ID enters the service-aware gateway. Directly identifying the SAN-ID to implement differentiated traffic diversion services is the key to implementing differentiated user services in the present disclosure. As shown in Figure 7, in order to introduce the complete service process, the association between control plane routing and SR policy and the data plane forwarding process are briefly described. The related process mainly includes the following parts:

1) Generation of SRv6 POLICY forwarding table entries: The control plane uses the head node or PCE centralized calculation according to the configuration policy issued by the intelligent management and control system, and finally forms the SRv6 POLICY forwarding table entry: SRv6-POLICY-MyPerFlow.

The SRv6 POLICY forwarding entry expresses the POLICY of the COLOR attribute 1000 from IGW to EGW, including the root The Border Gateway Protocol (BGP) publishes colored routes for all SRv6 POLICYs that are diverted according to the SAN-ID. In order to achieve automatic diversion on data devices, EGW usually adds the COLOR attribute when publishing routes and sets it as an integrated gateway (IGW) to match and install VPN routes and SRv6 POLICY, so as to achieve the precise intention of matching specific routes with on-demand matching POLICY.

2) Automatic matching and installation of head node VPN routing and SRv6 POLICY: After receiving the colored routing issued by EGW, IGW configures and installs it locally. Specifically, it searches for SRv6 POLICY based on the COLOR and NH IP carried in the routing as indexes. When the routing table is found, it is sent to the data plane to guide subsequent packet forwarding.

3) The service user initiates the connection service: the terminal/CPE sends a message carrying the corresponding SAN-ID identifier according to the application requirements.

4) IGW realizes business perception and service: IGW receives a business message carrying a SAN-ID identifier, first searches for a VPN route based on the destination IP, obtains the corresponding SRv6-POLICY-MyPerFlow information based on the hit route COLOR and NH, and then searches for the SRv6 POLICY that matches the corresponding SLA requirement based on the SAN-ID identifier, and encapsulates the SRH forwarding header to realize network differentiated diversion and forwarding. It should be noted that although the present disclosure expands the SAN-ID identifier diversion, it still maintains the DSCP-based diversion. When a message carrying a SAN-ID identifier matches the SAN-ID identifier, it is preferentially diverted based on the SAN-ID identifier. Messages that do not carry or carry but cannot match the SAN-ID identifier still use the Differentiated Services Code Point (DSCP) for diversion to maximize the expansion of device compatibility.

6. Business message recovery.

After the message reaches the service-aware egress gateway, the Segment Routing Header (SRH) is stripped according to the SID-carrying instruction of SLIST in SRH to restore the real user message. In particular, the following two scenarios need to continue to carry the service identifier:

1) In cross-domain scenarios, in order to continue to provide corresponding connection services in other domains.

2) In the downlink return scenario, differentiated connection services need to be supported, and the SAN-ID identifier must be carried to enter the service IP instance.

7. Downlink connection service.

When the SAN-ID identifier and service parameters are sent down, if the return SLA requirement is carried, a return SRv6 Policy corresponding to the SAN-ID identifier is created at the service-aware egress gateway. The service provider receives the upstream message carrying the SAN-ID identifier, and the response message still carries the SAN-ID identifier. The service gateway meets the downstream connection service SLA requirement through differentiated paths.

8. Two-way flow detection.

A specific SAN-ID tag expresses the connection service requirements of applications deployed on a specific service-aware egress gateway. Based on the service-aware ingress gateway to the service-aware egress gateway of a specific access service user, the SAN-ID tag expresses the connection service and the network SRv6 Policy service granularity is completely consistent. Therefore, business visualization is achieved for all messages with SAN-ID tags, which means that the corresponding service quality provided by the network is accurately and truly visualized. Further, based on the visualization data, dynamic challenges of SRv6 Policy can be achieved, SLA closed-loop repair and fault location can be achieved, and equipment resources such as Access Control List (ACL) and Segment Routing-Performance Monitoring Operations, Administration, and Maintenance (SR-PM OAM) can be saved. The specific implementation method is as follows:

1) At the service-aware ingress gateway, the SRV6 POLICY corresponding to the mapped SAN-ID identifier directly enables the in-flow detection configuration based on the SAN-ID identifier, where the endpoint of the POLICY represents the egress gateway.

2) The data plane receives a message carrying a SAN-ID identifier. After matching the corresponding SRV6 POLICY, if the flow detection configuration is enabled, the flow detection message is encapsulated. The corresponding flow detection technology can flexibly select intelligent network technology. Any of the following: Intelligent Networking Technology (INT), In-band OAM (IOAM), Information Flow Analysis (IFA), and In-band Operational Administration (InbandOAM).

3) Flow detection can support end-to-end (E2E) mode and be set to end-to-end performance detection, including packet loss, delay, and jitter detection. It can also support TRACE mode to achieve business path profiling, node and link packet loss positioning, etc.

4) The relevant detection results are reported to the intelligent control system through the telemetry mechanism at the service-aware ingress gateway and service-aware egress gateway to achieve fault demarcation, business trend and feature analysis, and SLA closed loop. The SLA closed loop means that when the E2E performance does not meet the SLA expectations, the controller dynamically triggers the regeneration of a new SRv6 POLICY and implements business matching, realizing the entire negative feedback automatic control adjustment for specific connection services, without the need to introduce segment routing performance monitoring (Segment Routing Performance Monitoring, referred to as SR-PM) and other tests for independent detection of SR POLICY. At the same time, the detection uses real business flows with good accuracy and authenticity.

5) The downstream and upstream flow detection mechanisms and methods are exactly the same and will not be elaborated here.

The embodiments of the present disclosure are applicable to the service-aware network innovation enhancement based on IPv6 network, realizing fine-grained programmable definition of services and SLA service assurance, maximizing network resource utilization and refined operation and maintenance. It should be noted that in order to simplify the description, the present invention uses IPv6/SRv6 network architecture to illustrate the main inventive concept, and the main features are still applicable to IPv4/MPLS network. The present disclosure:

1. Based on the existing network controller, a service management module for connection service registration and management and connection business policy issuance is added. Services are defined from the perspective of application service providers. Based on the differentiated key features of connection services, service export locations, and SLA requirements, unique digital identifiers are allocated using key features to achieve open feature management of connection services and issuance of unique corresponding identifiers. The key features are completely defined by the application provider, and are fully open and extensible. The planning of the coarse and fine granularity depends entirely on how they are defined, and no assumptions or constraints are made on the network domain.

2. Use digital identifiers to map corresponding service granules and SLA requirements in the network domain, so as to achieve accurate provision of connection services and SLA guarantees.

3. Based on the characteristics of digital identification, service location and SLA requirements being separated, network connection service requirements can be programmably adjusted and flexibly issued, meeting the flexible implementation and activation of massive connection service requirements and achieving precise operation and maintenance.

Compared with other existing proposed methods, the embodiments of the present disclosure are different from the prior art in that:

1. Compared with the passive method of five-tuple or deep packet inspection (DPI) identification and quality of service (QOS) annotation, the present invention directly defines the connection service from the perspective of application service provision and uses the terminal to carry a unique digital identifier to directly identify the network to provide service diversion and SLA guarantee, which is essentially different in technology.

2. Compared with the existing access point in IPv6 environment (Access Point Name 6, referred to as APN6), the main differences are:

The APN6 terminal side cannot express where the network exit is. The present disclosure does not define the connection requirements from the terminal perspective, and does not need to carry complex demand parameters. Instead, it directly defines the connection service from the perspective of application service provision and accurately expresses the service exit. The terminal only needs to carry a purely digital semantic identifier to receive services from the network.

The main difference is that the present disclosure adopts open service definition and programmability for connection services, and the service granularity of the present disclosure is not limited to the APN6 hierarchical definition, truly realizing connection as a service.

APN6 uses multi-parameter encapsulation, which brings overhead. Network devices need to perceive and process the internal classification semantics of the identifier. Performance is impaired and device processing is complex. This disclosure simplifies identification semantics and network device processing and improves performance by adding new capabilities to the control plane and management plane.

3. Compared with the service-aware network SAN, the present disclosure does not involve computing power awareness and computing-network joint scheduling decisions. It only uses digital identifiers to express network connection service types. The semantics and processes of service registration elements and providing differentiated services based on digital identifiers are completely different. The present disclosure can be considered as an extension and supplement to the connection service capabilities of SAN.

From the perspective of beneficial effects, the present invention has strong feasibility, adaptability to different scenarios, and scalability. Using the technical solution of the present invention, the rapid implementation of the service-aware network in the existing network environment can be accelerated directly based on the existing network upgrade software, and refined connection service management and guarantee capabilities can be achieved in the context of cloud-network integration, truly realizing Connectivity as a Service (CAAS), and having good economic value, as follows:

1. The service ID that runs through the end-network-cloud is openly mapped to the connection service granularity and is flexible and programmable, which reduces the difficulty of issuing connection services and configuring equipment.

2. Connection service perception based on the separation of service ID and network demand parameters. The concise digital identifier is carried through the message and actively expresses the connection service demand, avoiding resource consumption and security issues such as ACL/DPI, while reducing the pressure on the data plane chip and network bandwidth.

3. Directly implement traffic diversion based on service ID and enable flow measurement at the same time to achieve traffic feature characterization, fault location and service SLA closed loop, reduce resource consumption and improve service quality and operation and maintenance efficiency.

4. No modification is made to the intermediate nodes of the network equipment. Only the management plane and forwarding plane of the service-aware gateway node are involved. No modification is made to the control plane, thus achieving smooth upgrade and evolution of the existing network equipment.
