Problems solved by technology

Each master node in the cluster system also needs to be elected, and finally a global master master node, a global backup master node and N global common master nodes are elected, but there is currently no election scheme suitable for the cluster system

Abstract

The invention provides a node election method and device, and is applied to any master control node in a cluster system. The method comprises the steps that a handshake interaction message transmitted by a neighbor master control node is received, wherein the handshake interaction message carries the neighbor state of the present master control node sensed by the neighbor master control node; the locally recorded neighbor state of the neighbor master control node is updated according to the neighbor state of the present master control node sensed by the neighbor master control node; a global primary master control node is elected out of the master control nodes of the non-initial state according to locally recorded neighbor state of the master control nodes including the present master control node, wherein the non-initial state is the one-way state or the two-way state, and the neighbor state of the locally recorded present master control node is the default two-way state; and global backup master control nodes are elected out of the master control nodes of which the neighbor state is the two-way state apart from the global primary master control node. The election process is simple and easy to implement so that the election efficiency can be effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a node election method and device. Background technique [0002] The distributed IRF (Intelligent Resilient Framework) system implements stack election by exchanging STM (Stacking Management, stack management) protocol packets. The stack election process involves a large number of packet The master control node can participate in the election, and the local backup master control node can only do data backup. Finally, a global master control node and N global backup master control nodes are elected. [0003] The trunking system supports single chassis, back-to-back (B2B) and N+M (N represents the number of switching frames, M represents the number of line card frames) multi-frame. Each master node in the cluster system also needs to be elected, and finally a global master master node, a global backup master node and N global common master nodes are elected, but ther...
