DETAILED DESCRIPTION

In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

In order to solve the problem of missing existing network topology structure, the present application proposes a network topology construction method. FIG1 is a first flow chart of the network topology construction method in an embodiment of the present application. As shown in FIG1 , the network topology construction method may specifically include:

Step 101: Get the MAC address of the gateway;

Here, when it is necessary to build a network topology of a certain gateway, the MAC address of the gateway is obtained. Here, the MAC address of the gateway is used to determine the connection with the gateway, and then based on the connection, information interaction with the gateway is realized to obtain the connection relationship and device information of the terminal under the gateway. Exemplarily, the MAC address of the gateway is stored in the management platform. When the network topology of a certain home gateway is to be built, the MAC address of the home gateway is obtained from the database of the management platform; when the network topology of a certain office gateway is to be built, the MAC address of the office gateway is obtained from the database of the management platform.

Step 102: Based on the MAC address of the gateway, determine the downstream terminal that has a parent-child relationship with the gateway;

Here, the down-hook terminal having a parent-child relationship with the gateway is a down-hook terminal directly hung under the gateway. In the parent-child relationship, the gateway is the parent and the down-hook terminal is the child.

Exemplarily, based on the MAC address of the gateway, determining the downstream terminal having a parent-child relationship with the gateway includes: determining the connection between the gateway and the gateway based on the MAC address of the gateway; and exchanging information with the gateway based on the connection to determine the downstream terminal having a parent-child relationship with the gateway.

Exemplarily, in some embodiments, based on the mac address of the gateway, determining the downstream terminal that has a parent-child relationship with the gateway includes: based on the mac address of the gateway, determining the long connection between the gateway and the Andlink networking plug-in of the gateway; sending a first query request to the Andlink networking plug-in through the long connection; receiving a first query response sent by the Andlink networking plug-in; wherein the first query response includes identification information indicating the downstream terminal that has a parent-child relationship with the gateway; parsing the first query response to determine the downstream terminal of the gateway.

Step 103: When it is determined that the downstream terminal is a networking terminal, based on the MAC address of the networking terminal, determine a downstream terminal having a parent-child relationship with the networking terminal;

Exemplarily, the downstream terminals include networking terminals and non-networking terminals. Among them, the networking terminals can continue to connect to other networking terminals or smart terminals, which can be devices such as routers. Non-networking terminals are smart terminals such as mobile phones, computers, smart homes, etc., and cannot continue to connect to other networking terminals or non-networking terminals.

When it is determined that the downstream terminal is a networking terminal, it indicates that the downstream terminal may be connected to a lower-layer downstream terminal, and it is necessary to continue to obtain downward information.

In some embodiments, the method further includes: obtaining the MAC address of the downstream terminal; querying a terminal information database based on the MAC address of the downstream terminal to obtain device information of the downstream terminal; and determining whether the downstream terminal is a networking terminal based on the device information.

Exemplarily, FIG2 is a schematic diagram of a second process of the network topology construction method in an embodiment of the present application. As shown in FIG2, the network topology construction further includes:

Step 201: Obtain the MAC address of the terminal connected to the i-th layer;

Step 202: Based on the MAC address of the terminal connected to the i-th layer, query the terminal information database to obtain the device information of the terminal connected to the i-th layer;

Wherein, the terminal information library includes a mapping relationship between mac address and device information;

Step 203: judging whether the terminal under the i-th layer is a networking terminal based on the device information; if yes, executing step 204; if no, executing step 205;

Step 204: the i-th layer downstream terminal is a networking terminal, and based on the MAC address of the i-th layer networking terminal, an i+1-th layer downstream terminal having a parent-child relationship with the i-th layer networking terminal is determined;

Specifically, after the i+1th layer of downstream terminals is determined, the i+1th layer of downstream terminals is used as the i-th layer of downstream terminals, and the process returns to step 202 .

Step 205: The i-th layer connected terminal is a non-networked terminal and the query is stopped.

Exemplarily, in some embodiments, the device information of the downstream terminal includes a device type; the device type is used to indicate whether the downstream terminal is a networking terminal or a non-networking terminal.

Here, the terminal information database stores the MAC addresses of the downstream terminals and their corresponding device information; the device information of the downstream terminals can be obtained according to the MAC addresses of the downstream terminals. Here, the query is stopped because the i-th layer downstream terminal is a non-networking terminal, indicating that there will be no more downstream terminals connected to the i-th layer downstream terminal, that is, the i-th layer downstream terminal is the lowest layer downstream terminal.

When determining that the i-th layer of downstream terminals is a networking terminal, the next layer of networking terminals under the networking terminal is continuously obtained until the i-th layer of downstream terminals is a non-networking terminal, that is, the last layer of downstream terminals will not continue to connect to the downstream terminals and the downward acquisition is stopped. In this way, when constructing the network topology, all downstream terminals under the gateway can be obtained, avoiding the omission of downstream terminals and improving the integrity of the network topology structure.

Step 104: construct the network topology of the gateway by using the parent-child relationship between the gateway and its subordinate terminals, and the parent-child relationship between the networking terminal and its subordinate terminals.

For example, FIG3 is a network topology diagram in an embodiment of the present application, showing a constructed network topology. In FIG3, 300 is a gateway, 310-313 are first-layer down-hook terminals, where 310 and 313 are networking terminals; 320-326 are second-layer down-hook terminals, and there is no networking terminal in the second-layer down-hook terminals.

Here, the execution subject of steps 101 to 104 and steps 201 to 205 may be a processor of a network topology construction device. Exemplarily, the network topology construction device may be applied to a management platform to implement information interaction between the management platform and a gateway.

The technical solution of the present application, when determining that a networking terminal exists in a downstream terminal, obtains a next-layer networking terminal having a parent-child relationship with the networking terminal, so that when constructing a network topology, all downstream terminals under the gateway can be obtained, thereby avoiding omission of downstream terminals and improving the integrity of the network topology structure.

Based on the above embodiment, the method of determining the downstream terminal having a parent-child relationship with the gateway in step 102 and the method of determining the downstream terminal having a parent-child relationship with the networking terminal in step 103 are further illustrated.

Exemplarily, in some embodiments, based on the mac address of the gateway, determining the downstream terminal that has a parent-child relationship with the gateway includes: based on the mac address of the gateway, determining the long connection between the gateway and the Andlink networking plug-in of the gateway; sending a first query request to the Andlink networking plug-in through the long connection; receiving a first query response sent by the Andlink networking plug-in; wherein the first query response includes identification information indicating the downstream terminal that has a parent-child relationship with the gateway; parsing the first query response to determine the downstream terminal of the gateway.

Here, the long connection is used to realize the information interaction between the management platform and the Andlink networking plug-in. The first query request is used to query the downstream terminals that have a parent-child relationship with the gateway. Exemplarily, the identification information includes: mac address, name.

Exemplarily, in some embodiments, based on the MAC address of the networking terminal, determining the downstream terminal that has a parent-child relationship with the networking terminal includes: sending a second query request to the networking terminal based on the MAC address of the networking terminal; receiving a second query response sent by the networking terminal; wherein the second query response includes identification information indicating the downstream terminal that has a parent-child relationship with the networking terminal; parsing the second query response to determine the downstream terminal of the networking terminal.

Here, the second query request is used to query the downstream terminal that has a parent-child relationship with the networking terminal. Exemplarily, the identification information includes: mac address and name.

Exemplarily, in some implementations, the second query response further includes: operating parameters of the networking terminal. The operating parameters may be information such as the current negotiated receiving rate, the current negotiated sending rate, the uplink real-time receiving rate, the uplink real-time sending rate, etc. of the networking terminal. The method further includes: displaying the operating parameters of the networking terminal in the network topology.

Exemplarily, in some embodiments, the query gateway and the lower-hanging terminal of the networking terminal can be implemented by the Andlink networking plug-in of the management platform gateway, the networking terminal, and the information interaction structure between the intelligent terminal. In the information interaction structure, the information interaction between the Andlink networking plug-in, the networking terminal, and the intelligent terminal can be implemented based on the Andlink protocol. Here, the intelligent terminal is equivalent to the non-networking terminal in this application.

Exemplarily, FIG4 is an information interaction structure diagram in an embodiment of the present application. As shown in FIG4 , information can be directly exchanged between the management platform and the Andlink networking plug-in; information can be exchanged between the Andlink networking plug-in and the networking terminal and the smart terminal; the networking terminal can exchange information with the next-layer smart terminal hanging below it. Here, the management platform can be used to query/control the networking terminals and smart terminals, and can also store terminal information of the entire network. The Andlink networking plug-in of the gateway is a plug-in that complies with the Andlink protocol in the gateway. It can be used to access the management platform upward, maintain and manage the smart networking terminals downward, and transfer messages and data between the management platform and the networking terminals and smart terminals. The networking terminals are mainly routers, etc., which are responsible for increasing the coverage and signal strength of the network. The smart terminal is embedded with the Andlink sdk, and the device information of the terminal can be sent when the terminal is accessed.

Exemplarily, in some embodiments, sending a second query request to the networking terminal based on the mac address of the networking terminal includes: sending a second query request to the Andlink networking plug-in of the gateway based on the mac address of the networking terminal, so that the Andlink networking plug-in forwards the second query request to the networking terminal; receiving the second query response sent by the networking terminal includes: receiving the second query response of the networking terminal forwarded by the Andlink networking plug-in.

Through the long connection between the management platform and the gateway Andlink networking plug-in, the query request is sent to the downstream terminal, and the query response sent or forwarded by the gateway Andlink networking plug-in is received. The terminal can be connected in real time for real-time query to improve the query efficiency. It can also provide a basis for applications on the topology structure, such as displaying the scope of home network alarms, and a unified management entrance can be used for smart home devices of various manufacturers to start, stop, query and other operations.

In order to further illustrate how to determine the downstream terminals of the gateway and the networking terminal based on the information interaction structure in Figure 4, the present application provides the following examples.

Exemplarily, FIG5 is a flowchart of information interaction among the management platform, the Andlink networking plug-in, and the downstream terminal in an embodiment of the present application.

As shown in Figure 5, the information interaction mainly includes the following contents:

501: The Andlink networking plug-in obtains the MAC address information of the gateway, registers and authenticates with the management platform, and establishes a TCP long connection and a heartbeat to keep it alive;

502: When the networking terminal/intelligent terminal is connected to the gateway for the first time, the terminal sends the device information and parameters to the Andlink networking plug-in through broadcasting for registration;

503: The Andlink networking plug-in returns a registration response and reports device information and parameters to the management platform for terminal registration;

504: The management platform records the corresponding information and stores it in the database, and returns a terminal registration response to the Andlink networking plug-in.

505: The terminal periodically reports the heartbeat to the Andlink networking plug-in through broadcasting;

506: The management platform initiates a query control request to the Andlink networking plug-in;

507: After receiving the query control request command, the Andlink networking plug-in makes a judgment. If it is a query for the relevant information of the gateway itself, it returns directly; if it is a request to query the terminal connected to it, it is forwarded to the corresponding terminal.

508: The terminal responds to the query control operation and returns a query control response;

509: The Andlink networking plug-in forwards the query control response returned by the terminal to the management platform.

The content of the request and response between the networking terminal/intelligent terminal and the gateway Andlink networking plug-in is similar to the content of the request and response between the gateway Andlink networking plug-in and the management platform. Exemplarily, when the gateway is a home gateway, the content of the registration and query request and query response is as follows.

Exemplarily, the registration request content of the networking terminal is as follows:

By extending the nodes of the topology structure to the intelligent terminal layer, the topology structure is made more complete; by sending a query request to the downstream terminal based on the long connection between the management platform and the gateway Andlink networking plug-in, and controlling the Andlink networking plug-in to directly return or forward to the networking terminal, and returning the query result to the management platform, the terminal can be queried in real time to improve the query efficiency; it can also provide a basis for applications on the topology structure, such as displaying the scope of network alarms, and a unified management entrance for smart devices of various manufacturers to start, stop, query and other operations.
