Abstract： |
The method comprises: creating a neighbor state table comprising a threshold value used for indicating how many continuously-lost detection messages can confirm a failure node, and the flag bit for indicating the agent status of the node; said neighbor state table is used for calculating the transmission frequency of the detection messages and creating a neighbor maintenance table containing the amount of keep-alive messages and the transmission frequency; if a detection confirmation message is not received said in amounts indicated by threshold value from a neighbour, said neighbor will be deleted; if the deleted neighbour is an agent node of the area, then making a fast switch and an election of standby nodes in order to keep the continuity of the network service in shortest time. |
