Background technique

The popularization of 5G networks has led to a surge in demand for network bandwidth in data centers. In order to alleviate bandwidth pressure and improve user experience, companies often choose content distribution networks (CDNs) to accelerate data transmission.

Content distribution network adds a new network architecture to the existing Internet, publishes the content of the website to the "edge" of the network closest to the user, so that the user can get the required content nearby, and improve the response speed of user access to the website. CDN service providers usually deploy servers and carry CDN application needs by leasing data centers.

Detailed ways

The present application is described more fully below with reference to the accompanying drawings in which illustrative embodiments of the present application are illustrated. However, the present application may be implemented in different forms and should not be interpreted as being limited to the embodiments given herein. The above embodiments are given to make the disclosure herein comprehensive and complete, so as to more fully convey the scope of protection of the present application to those skilled in the art.

In this specification, terms such as "comprise" and "include" indicate that in addition to the units and steps directly and explicitly stated in the specification and claims, the technical solution of the present application does not exclude the situation where there are other units and steps that are not directly or explicitly stated.

Terms such as "first" and "second" do not indicate the order of the units in terms of time, space, size, etc., but are only used to distinguish the units.

In this specification, a router refers to a hardware device that connects two or more networks and acts as a gateway between networks. It is a dedicated intelligent network device that reads the address in each data packet and then decides how to transmit it. In the following description, unless otherwise specified, the terms "router" and "gateway device" can be used interchangeably.

In this specification, blockchain refers to a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. It can essentially be understood as a decentralized database that uses cryptographic methods to generate data blocks. Each data block contains information related to the application scenario and can be used to verify the validity of the information and generate the next data block.

In some embodiments of the present application, a blockchain network with a router or gateway device as a node is constructed, and nodes or router nodes (in this specification, unless otherwise specified, the terms "node" and "router node" can be used interchangeably.) are used to cache website access content (for example, in the form of mirror backup); at the same time, the access data associated with the cached website access content is added to the data block of each blockchain node or to the blockchain network (in this specification, unless otherwise specified, the operation of adding access data to the data block is equivalent to the operation of adding access data to the blockchain network). When the node receives a website access request from a terminal device, it determines whether the content of the website to be accessed has been cached in the blockchain network based on the access data or data block (that is, whether there is a node that has cached the content of the website to be accessed). If such a node exists, the access request is redirected to the corresponding node, thereby achieving CDN acceleration. Optionally, if such a node does not exist, the access request is redirected to a public domain name resolution server. Due to the traceability, openness, independence and security of blockchain data, CDN services based on blockchain networks have higher reliability and scalability, and the billing mechanism is more transparent.

In some embodiments of the present application, optionally, when there are multiple nodes caching the content of the website to be accessed, a node is selected from them based on one or more of the following items: a node is selected from them based on one or more of the following items: i) the degree of match between the IP address of the node and the IP address of the terminal device; ii) the distance between the geographical location of the node and the geographical location of the terminal device; and iii) the version number of the content of the website to be accessed cached at the node. Exemplarily, an IP address with a higher degree of match with the IP address of the terminal device can be used as an access address, or a node closer to the geographical location of the terminal device can be used as a redirected node, or a node or address corresponding to the website content with a higher version number can be used as a redirected node or access address. Optionally, a comprehensive score can be obtained by assigning corresponding weight factors to the degree of IP address match, the distance between geographical locations, and the version number of the cached content, and the one with a higher comprehensive score is determined as a redirected node or access address.

In some embodiments of the present application, in order to enable external devices to access the website content cached by the node, a corresponding access address is configured as access data. Optionally, the router can use the UPnp protocol to automatically allocate the public network IP and port for external services to the cached content as the access address for IPv4, and the external device can directly access the cached content based on the access address. In order to solve the problem of scarce IPv4 address resources, many countries in the world are currently promoting the IPv6 protocol. Optionally, the access address assigned to the cached content can be based on the IPv6 protocol. In this case, the IP address and port number of the cached content can be fixed. In addition, the access data may also include the version number of the cached website content and the geographical location of the node.

In some embodiments of the present application, optionally, when a change is found in the public IP address of the router (for example, due to device restart, DHCP lease expiration, etc.), access data reflecting the change is added to the data block of each node.

In some embodiments of the present application, optionally, when a new node joins the blockchain network, the data blocks of each node in the blockchain network are updated.

FIG1 is a schematic diagram of the structure of a blockchain network for implementing edge computing network acceleration according to some embodiments of the present application.

The blockchain network 10 shown in Figure 1 includes multiple nodes 101-110, which can be directly connected to each other or indirectly connected through other nodes. It should be noted that the number of nodes shown here is only exemplary and should not be understood as any limitation to the embodiment.

Each of the nodes 101-110 in Figure 1 has a block function, by means of which the data or access data of the website content accessed via this node can be added to the data block of this node. On the other hand, each of the nodes 101-110 also has a routing function, so that the access data and other information transmitted by other nodes can be transmitted to more nodes to realize the update of data blocks in the entire blockchain network. The data block described here is a data structure that records access data. Exemplarily, each data block consists of a block header and a block body. The block body records all access data in the blockchain network in the previous period of time, and the function of the blockchain is mainly realized by the block header.

In the embodiment shown in FIG1 , nodes 101-110 are routers or gateway devices, which are configured to store and forward packets between different networks (e.g., between a local area network and the Internet). In network communications, a router has the function of determining a network address and selecting an IP path, and can build a flexible link system in multiple network environments, linking each subnet through different data packets and media access methods.

Optionally, nodes 101-110 in FIG. 1 are broadband routers. Exemplarily, a broadband router can integrate functions such as a router, a firewall, bandwidth control and management, and has fast forwarding capabilities. Most broadband operators bundle the MAC address with the user's ID and IP address to authenticate the user's Internet access. A broadband router with a MAC address function can write the MAC address on the network card, allowing the server to obtain broadband access authentication through MAC address verification during access. Broadband routers usually provide a NAT function to convert the IP address assigned to each terminal device in the local area network into a legally registered actual IP address of the Internet network, so that the terminal devices in the internal network can communicate directly with other hosts on the Internet. When a home broadband router is used as a node in a blockchain network, costs can be reduced and bandwidth utilization can be improved by sharing home broadband. In addition, home broadband routers are usually the edge nodes closest to user devices, so they are very suitable for building content distribution networks.

FIG2 is a flowchart of a method for implementing edge computing network acceleration according to some other embodiments of the present application.

The method flow shown in FIG2 includes the following steps:

Step S201: construct a blockchain network including routers as nodes. Exemplarily, the constructed blockchain network may have the network structure and features shown in FIG1 , which will not be described in detail here.

The following steps S202 - S204 may be executed in parallel after step S201 .

Step S202: When an event that triggers the update of a data block occurs, a data block update operation is performed in the blockchain network. Events that trigger the update of a data block include, but are not limited to, the addition of a new node in the blockchain network, changes in cache content at a node, and changes in a node address. The update operation will be further described below with reference to FIG3.

Step S203: When receiving an access request from a terminal device, a processing operation for the access request is performed in the blockchain network. The processing operation will be further described below with reference to FIG. 4 .

Step S204: When a query request is received from a terminal device, historical data of the mobile terminal accessing the Internet via the blockchain network is queried in the data block of the blockchain network. The processing operation of the query request will be further described below with reference to FIG5.

FIG. 3 is a flowchart of a method for updating a data block according to some other embodiments of the present application.

The method flow shown in FIG3 includes the following steps:

Step S301: When accessing the content of website A via a node in the blockchain network (hereinafter taking node 108 as an example), node 108 will synchronously cache the content of website A. Optionally, the content of website A is stored at node 108 in a mirrored backup manner.

Step S302: Node 108 generates access data associated with cached content. Optionally, the access data includes an access address configured for accessing the content of website A cached on node 108. Exemplarily, the access address can be an IP address and port number based on the UPnp protocol, or an IP address and port number based on the IPv6 protocol. Alternatively, the access data further includes a version number of the cached website content and a geographic location of node 108.

Step S303: the node 108 writes the access data into the data blocks of the node and other nodes.

Step S304: When the access address configured for the cached content of website A at node 108 changes, node 108 will generate corresponding access data.

Step S305: the node 108 adds the access data reflecting the change to the data blocks of the node and other nodes.

Step S306: When a new node (such as node 111) joins the blockchain network, nodes 101-110 will update their respective data blocks.

FIG. 4 is a flowchart of a method for processing an access request according to some other embodiments of the present application.

The method flow shown in FIG4 includes the following steps:

Step S401: One of the nodes of the blockchain network (hereinafter taking node 106 as an example) receives an access request from a terminal device, where the access request includes an instruction to access website A.

Step S402: Node 106 determines whether there is a node in the blockchain network that caches the content of website A based on the data blocks stored thereon. If there is a node that caches the content of website A, then proceed to step S403, otherwise proceed to step S404.

Step S403: Return the access address assigned to the content to the terminal device or redirect the access request to a corresponding node (eg, node 108).

In this step, when there are multiple nodes caching the content of website A to be accessed, as described above, the redirected node or access address can be determined based on one or more of the following items: the degree of match with the IP address of the terminal device, the distance from the geographical location of the terminal device, and the version number of the content of website A.

Step S404: Node 106 redirects the access request to a public domain name resolution server.

FIG5 is a flowchart of a method for processing a query request according to some other embodiments of the present application.

The method flow shown in FIG5 includes the following steps:

Step S501: One of the nodes of the blockchain network (hereinafter taking node 106 as an example) receives a query request from a terminal device, and the query request includes an identification ID of the terminal device.

Step S502: Node 106 queries the historical data of the terminal device specified by the identification ID accessing the Internet via the blockchain network in the data block stored thereon.

Step S503: the node 106 returns the query result to the mobile terminal.

In the embodiment shown in FIG. 5 , the mobile terminal may access the Internet via multiple nodes in the blockchain network, or the mobile terminal may not access the Internet via the node that sends the query request (e.g., node 106). However, since the data block of each node records all historical data of the terminal device accessing the Internet via the blockchain network, the mobile terminal can still query its history of accessing the Internet via the blockchain network through any node.

FIG6 is a flowchart of a method for implementing edge computing network acceleration according to some other embodiments of the present application.

The method flow shown in FIG6 is executed by the terminal device and includes the following steps:

Step S601: Send an access request including an indication of wanting to access website A to one of the nodes (e.g., node 106) of a blockchain network including multiple routers as nodes (exemplarily, the blockchain network may have the network structure and features shown in FIG. 1 ).

Optionally, the application of the terminal device may have built-in access policies that designate nodes in the blockchain network as nodes that are preferentially accessed when accessing the Internet.

Step S602: Obtain the content of the website to be accessed based on the access address returned by the node 106. In the example, it is assumed that the content of website A is cached on the node 108, so the access address returned by the node 106 will point to the node 108. Optionally, the access address can be an IP address and port number based on the UPnp protocol, or an IP address and port number based on the IPv6 protocol.

Step S603: Send a query request to one of the nodes (e.g., node 103) of the blockchain network, the query request including the identification ID of the terminal device. Based on the identification ID, node 103 can query the historical data of the terminal device specified by the identification ID accessing the Internet via the blockchain network in the data block stored therein.

Step S604: receiving query results or historical data of terminal device accessing the Internet from the node 103 .

It should be noted that in the embodiment shown in Figure 6, the order of the access request sending step and the query request sending step is merely exemplary and not limiting. Optionally, steps S603 and S604 may precede steps S601 and S602, or steps S601 and S602 and steps S603 and S604 may be executed in parallel.

Fig. 7 is a schematic block diagram of a typical terminal device. Referring to Fig. 7, the terminal device 70 includes a communication unit 710, a memory 720 (e.g., a non-volatile memory such as a flash memory, a ROM, a hard disk drive, a magnetic disk, an optical disk, etc.), a processor 730, and a computer program 740 stored in the memory 720 and executable on the processor 730.
