Method for optimizing client declaration process in MESH network routing protocol

Abstract

The invention discloses a method for optimizing a client declaration process in the MESH network routing protocol and mainly aims at solving the problem that the number of clients that the existing network serves is restricted by the size of a probe packet. The implementation scheme of the method comprises the following steps: when the local conversion table of a source node changes, the source node broadcasts the probe packet to other nodes in the network; after receiving the probe packet, a receiving node judges whether the content of the probe packet is correct or not according to the variation of a domain VN value, and if the content of the probe packet is wrong, the receiving node sends a request packet to the source node, and a passing node blocks the request packet if the passing node finds itself carrying correct information, and returns a reply packet containing the correct information to the receiving node; and if the content of the probe packet is correct, a data link table segment corresponding to the source node in a global conversion table is directly updated, and then the optimization of the client declaration process in the MESH network routing protocol is completed. The method reduces the quantity of useless information carried in the probe packet, the network load and the network overload.

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...

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.
