BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Hereinafter, the present invention will be described in more detail based on embodiments with reference to the accompanying drawings.

[0044] Figure 1 This is a flow chart of a network router management method provided by one embodiment of the present invention;

[0045] Figure 2 This is a schematic diagram of a network router management system provided by one embodiment of the present invention. DETAILED DESCRIPTION

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] A router is a hardware device that connects two or more networks, acting as a gateway between them. It is a specialized intelligent network device that reads the address in each data packet and determines how to transmit it. It understands different protocols, such as the Ethernet protocol used by a local area network and the TCP / IP protocol used by the Internet. Thus, a router can analyze the destination addresses of data packets from various networks, converting non-TCP / IP network addresses into TCP / IP addresses and vice versa. It then uses a selected routing algorithm to deliver each data packet along the optimal route to its destination.

[0048] Routing protocols are a crucial concept in networking, responsible for delivering data packets from source nodes to destination nodes. Routing protocols define the communication rules and data transmission methods between different routers in a network, effectively transferring data packets from the source address to the destination address. In the networking world, there are many different routing protocols to choose from, such as RIP (Routing Information Protocol), OSPF (Open Shortest Pass First), and IGRP (Interior Gateway Routing Protocol). In these routing protocols, routers typically need to continuously send their routing tables to ensure the accuracy of the information in each router's routing table. However, routers in a network are typically in a relatively stable state, with only a small number of routers leaving the network. In this case, sending routing tables to ensure the accuracy of each router's routing table would result in a significant network load, impacting network transmission speeds.

[0049] First, as Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present application provides a network router management method, including:

[0050] S101: Collect the target routing address of the target router through the address collector in the routing interface circuit;

[0051] S102: When the target router exits the network, trigger the routing interface circuit to send routing exit information to other routers, wherein the routing exit information includes the target routing address;

[0052] S103: Searching other routing tables of the other routers based on the target routing address, and marking and / or deleting entries in the other routing tables that include the target routing address.

[0053] It should be noted that current routing protocols typically require routers to send their own routing tables to keep the routing tables of routers in the network consistent. However, the routing table has a large amount of data and each time a routing table is sent, a large amount of network resources is consumed. In an embodiment of the present application, an address collector is set in an interface circuit connected to the router (i.e., the routing interface circuit). When the router accesses or exits the network, the address collector can collect the target routing address of the target router, and then generate routing access information or routing exit information based on the target routing address. The routing access information and / or routing exit information can be sent to the routers in the network so that the routers in the network can update their own routing tables based on the routing access information and / or routing exit information, thereby ensuring the accuracy of the routing tables of the routers in the network. The routing interface circuit can be set on a cable or wire connected to the target router. The routing access information can be composed of the target routing address and an access tag. The routing exit information can be composed of the target routing address and an exit tag. The exit tag can be an infinite distance.

[0054] In some embodiments, the routing interface circuit includes a head-end interface circuit and a tail-end interface circuit;

[0055] The step of collecting the target routing address of the target router by the address collector in the routing interface circuit includes:

[0056] Collecting the target routing address of the target router through the address collector in the head-end interface circuit;

[0057] Collecting adjacent routing addresses of other routers adjacent to the target router through the address collector in the tail end interface circuit;

[0058] The target routing address is sent to the address collector in the tail-end interface circuit, and the adjacent routing address is sent to the address collector in the head-end interface circuit.

[0059] In some embodiments, collecting the target routing address of the target router by the address collector in the routing interface circuit further includes:

[0060] A path detection signal is periodically sent to the head-end interface circuit via the tail-end interface circuit to detect whether the target router is connected to the other adjacent routers.

[0061] It should be noted that after the target routing address is sent to the address collector in the tail-end interface circuit, the target routing address is stored in the address collector of the tail-end interface circuit; after the adjacent routing address is sent to the address collector in the head-end interface circuit, the adjacent routing address is stored in the address collector of the head-end interface circuit, that is, the address collector of the head-end interface circuit and the address collector of the tail-end interface circuit respectively store the target routing address and the adjacent routing address.

[0062] It should be noted that, by respectively storing the target routing address and the adjacent routing address in the address collector of the head-end interface circuit and the address collector of the tail-end interface circuit, and causing the tail-end interface circuit to periodically send a path detection signal to the head-end interface circuit (or causing the head-end interface circuit to periodically send a path detection signal to the tail-end interface circuit), it is possible to detect whether the connection between the target router and the other adjacent routers is disconnected. When the connection between the target router and the other adjacent routers is disconnected, the routing exit information can be generated using the target routing address in the address collector of the tail-end interface circuit, and the routing table of the router in the network can be updated based on the routing exit information. The specific time of the periodicity can be set as needed, such as 0.5s, etc., and this application does not impose specific restrictions on this.

[0063] It should be noted that if the target router has not exited the router network but has only been disconnected from other adjacent routers, the exit mark may be an infinite distance. Detecting whether the target router has exited the router network may be achieved by the tail-end interface circuit periodically sending a path detection signal to the head-end interface circuit. If all other routers connected to the target router are disconnected, it is determined that the target router has exited the router network. If the target router has not exited the network but has only been disconnected from one or several adjacent routers, routing disconnection information may be sent to the router network via the tail-end interface circuit disconnected from the target router (the tail-end interface circuit being connected to other routers). The routing disconnection information may include the target router address, the addresses of the other routers disconnected from the target router, and an infinite distance.

[0064] In some embodiments, collecting the target routing address of the target router by the address collector in the routing interface circuit further includes:

[0065] Detecting the routing table of the target router;

[0066] If the routing table of the target router does not increase or decrease routing entries within a preset steady-state threshold, then the routing table is stopped from being sent to the other routers adjacent to the target router.

[0067] It should be noted that when routers are networked, the routing tables of the routers in the entire network can be made consistent and unified in a short period of time by making the routers send routing tables. However, after the router networking is completed, the routers in the entire network are in a relatively stable state, that is, usually not too many routers join or leave the router network. At this time, stopping the routers in the network from sending routing tables can reduce the network load and improve the network speed. The routing table of the target router does not increase or decrease routing entries within the preset steady-state threshold, which indicates that the router network is in a relatively stable state. Among them, the preset steady-state threshold can be set according to actual needs, such as 5 minutes, etc., and this application does not make specific restrictions on this.

[0068] In some embodiments, when the target router exits the network, the routing interface circuit is triggered to send routing exit information to other routers, wherein the routing exit information includes the target routing address, including:

[0069] When the target router exits the network, determining a diffusion center area and a plurality of diffusion peripheral areas outside the diffusion center area with the target router as the center and a preset distance threshold as the range;

[0070] triggering the routing interface circuit to send the routing exit information to the routers in the diffusion center area, wherein the routing exit information includes the target routing address;

[0071] The route exit information is sent to the diffusion peripheral area through the edge router of the diffusion central area.

[0072] It should be noted that the current routing protocol usually floods each routing node when sending a routing table. This will cause the problem of repeated sending and receiving of the same routing table, wasting network resources. The embodiment of the present application divides the routers in the entire routing network into a diffusion center area and multiple diffusion peripheral areas, so that when sending the routing exit information and / or routing join information, flooding is only performed within the diffusion center area and the diffusion peripheral area, and between the diffusion center area and the diffusion peripheral area, it is sent through the edge router, thereby avoiding the problem of wasting network resources caused by flooding the routing exit information and the routing join information in the entire network.

[0073] It should be noted that the diffusion center area and the multiple diffusion peripheral areas outside the diffusion center area are determined with the target router as the center and the preset distance threshold as the range. Specifically, the diffusion center area is determined with the target router as the center and the preset distance threshold as the range, and multiple candidate diffusion centers with a distance of 2 times the preset distance threshold from the target router are determined. From the multiple candidate diffusion centers, several candidate diffusion centers with a distance of 2 times the preset distance threshold are selected as peripheral diffusion centers, and multiple peripheral diffusion areas are determined with the peripheral diffusion centers and the preset distance threshold as the range.

[0074] In some embodiments, sending the route exit information to the diffusion peripheral area through the edge router of the diffusion central area includes:

[0075] Determine at least one edge router based on the distance between the routers in the diffusion center area and the target router and the distance between the routers in the diffusion center area and the center of the diffusion peripheral area;

[0076] The route exit information is sent to the diffusion peripheral area through the edge router.

[0077] It should be noted that the at least one edge router is determined based on the distance between the router in the diffusion center area and the target router and the distance between the router and the center of the diffusion peripheral area. Specifically, the distance between the edge router and the target router is one unit distance (or a starting point) smaller than the distance between the edge router and the center of the diffusion peripheral area (i.e., the peripheral diffusion center).

[0078] In some embodiments, the at least one edge router is a plurality of edge routers;

[0079] The sending the route exit information to the diffusion peripheral area through the edge router includes:

[0080] Obtaining edge routing tables of a plurality of edge routers;

[0081] Obtaining the number of externally connected routers of the edge router based on the router addresses included in the diffusion center area and the edge routing table;

[0082] Obtaining an edge sending router from a plurality of edge routers based on the number of externally connected routers;

[0083] The routing exit information is sent to the diffusion peripheral area through the edge sending router.

[0084] It should be noted that the edge sending router is obtained from multiple edge routers based on the number of externally connected routers, specifically: an edge router with a large number of externally connected routers is selected as the edge sending router, so as to improve the sending efficiency and avoid repeated sending. Among them, the externally connected routers of multiple edge routers can also be compared, and multiple edge routers with different externally connected routers or less repeated external routers are selected as the edge sending routers, so as to further improve the sending efficiency and avoid repeated sending.

[0085] In some embodiments, the target router includes a plurality of transmitting antennas, a reflector disposed outside the transmitting antennas, and a reflector adjustment device connected to the reflector;

[0086] The network router management method further includes:

[0087] Obtaining a usage area map of the target router space;

[0088] The angle of the reflector is adjusted by the reflector adjustment device based on the usage area map to cover only the usage area of the target router.

[0089] It should be noted that the target router described here is a router used by the user end, such as a router for home use, a router for office use, etc., and in a home or office, the target router is usually not placed in the center of the use area, but in a corner, and the transmitting antenna of the router is usually an omnidirectional antenna, that is, it sends wireless signals evenly in all directions, which will lead to insufficient signal strength in some use areas, while other areas where signals are not used have problems with wireless signals. The embodiment of the present application adjusts the angle of the reflector through the reflector adjustment device according to the use area map, so that the wireless signal only covers the use area of the target router, enhances the signal strength of the use area, and avoids covering areas where wireless signals are not used. The use area map can be obtained by user import, and the target router may also include a positioning and orientation sensor to determine the position and direction of the target sensor itself, so as to accurately adjust the angle of the reflector.

[0090] In some embodiments, obtaining a usage area map of the target router space is specifically:

[0091] Acquire an infrared image of the target router space using an infrared imaging sensor;

[0092] The usage area map is obtained based on the infrared image.

[0093] It should be noted that an infrared imaging sensor can obtain an infrared image of the target router space and an infrared image of human activities in the target router space. By combining the infrared image of human activities and the infrared image of the target router space, the usage area map can be obtained, thereby reducing the trouble of the user inputting the usage area map.

[0094] In summary, the present application provides a network router management method, comprising collecting a target routing address of a target router through an address collector in a routing interface circuit; when the target router exits the network, triggering the routing interface circuit to send routing exit information to other routers, wherein the routing exit information includes the target routing address; searching other routing tables of the other routers based on the target routing address, and marking and / or deleting entries in the other routing tables that include the target routing address. When a router exits the network, routing exit information can be sent through the routing interface circuit, which can solve the problem that the accuracy of each router's routing table is currently ensured by sending routing tables, resulting in a large network load and affecting the network transmission speed, thereby reducing the network load and improving the network transmission speed.
