Problems solved by technology

When the network scale expands, the number of clients served by each MESH node will increase rapidly. If the "send all" mechanism is adopted, the detection packets that the MESH node needs to send to other nodes in the network must include all old clients and new access nodes. Therefore, the amount of information transmitted in the network will increase instantaneously. However, due to the limited storage capacity of the detection packet, it cannot carry all the client information after expansion at the same time for transmission, resulting in the number of clients that can be connected simultaneously in the MESH network. Restricted

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the effects of the present invention will be verified below in conjunction with the accompanying drawings and simulation results.

[0022] refer to figure 1 , the MESH network is composed of a wireless controller AC, a wireless access point AP and a client, wherein the wireless controller AC controls and manages the wireless access point AP in the MESH network; the wireless access point AP has 3 types : One is the wireless access point MPP connected to the wireless controller AC through a cable, the other is the wireless access point MP connected to the MPP but not connected to the client, and the third is the wireless access point MAP that provides access services for the client . These three types of wireless access point AP constitute the framework of the MESH network. Wireless access point APs can automatically discover each other and initiate the establishment of multi...

Abstract

The invention discloses a method for optimizing the client declaration process in the MESH network routing protocol, which mainly solves the problem that the number of clients served by the existing network is limited by the size of the detection packet. The implementation plan is: when the local conversion table of the source node changes, the source node broadcasts the detection packet to other nodes in the network; after receiving the detection packet, the receiving node judges whether the content of the detection packet is correct according to the change of the domain VN value , if the content of the detection packet is wrong, the receiving node sends a request packet to the source node, and if the passing node finds that it carries correct information, it blocks the request packet, carries the correct information in the reply packet, and sends it back to the receiving node; If the content of the detection packet is correct, the data link table segment corresponding to the source node in the global conversion table is directly updated to complete the optimization of the client declaration process in the MESH network routing protocol. The invention reduces the amount of useless information carried in the detection packet, reduces the network load, and reduces the network overhead.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a client declaration process optimization method, which can be used for the improvement of the MESH network routing protocol. Background technique [0002] In a network with multiple clients, an a priori routing protocol is a commonly used routing protocol. In this routing protocol, regardless of whether there is a need for communication, each node adopts the method of periodically broadcasting probe packets containing complete routing information, and maintains a routing table containing routing information to other nodes, that is, a local translation table. When a change in the network topology is detected, the node will send a probe packet containing an update message in the network. The node receiving the update message will update its own local translation table to ensure the accuracy of routing information. Once the source node wants to send a packet, it...
