Route renewing method based on converying type network system

Abstract

This invention discloses a route refresh method for an accumulated network system including: each node in said system sends a route refresh frame containing its own node identification to the master control node and each node passed through by said route refresh frame and its master control node refresh their own route list based on the node identification contained in the frame orderly.

Description

Technical field [0001] The present invention relates to the routing information management technology of a network system, in particular to a routing update method based on a convergent network system. Background technique [0002] Converged network system means that all network nodes in the network system are physically connected in a hierarchical structure, where the master node is located at the highest level and is used to initiate control signaling; each node under the control of the master node refers to A communication device that participates in control signaling transfer. In this way, in a convergent network system, there is only one route for transmitting control signaling between the master node and each node; and there is a connection between two nodes that have a control signaling transmission relationship. Relationship, and among the two nodes that have a connection relationship, the node close to the master node is called the upstream node, and the other node is ca...

[0008] However, it is obvious that the above-mentioned method of updating the route of the converged network system using a fixed route method needs to first determine the nodes that the route to be updated will pass through, and then manually update the route for each passing node one by one. The following defects exist:

[0014] However, in a converged network system, when an intermediate node is added, it only needs its upstream node to know the news and change the routing information accordingly. Its downstream nodes do not need to be notified, and this dynamic learning-based The routing update method does not take this into consideration, so there must be some inevitable defects in the implementation process, as follows:

[0015] a. When there are other nodes in the entire convergence network system, such as node 4 in Figure 1, this node 4 can also be regarded as a router, and the master control node will also notify the routing change message that node 3 joins the system to node 4, and will broadcast the route change message to every node in the system; however, in fact, it is only necessary to establish a route between the master node and node 3, and other irrelevant nodes do not need to be notified Therefore, this routing update method is likely to cause excessive transmission of unnecessary notification messages in the system. In severe cases, it may cause a message storm in the network system; and it will seriously disturb the stability of the entire network system;

[0016] b. At the same time, due to the excessive transmission of unnecessary notification messages, this route update method may take up the time of the route update process, so the processing efficiency is relatively low
