Method for reconfiguring a ring network, a network node, and a computer program product

摘要

A method of reconfiguring a ring network having a plurality of nodes connected by a plurality of links, comprising initiating reconfiguring of one of the nodes in response to a network change message received over a link connected thereto from an adjacent node, blocking said link by the one node, reconfiguring network information stored on the one node, flushing any old queued messages on said one node and, in response to completion of said flushing, sending a reconfigured message to the other node adjacent thereto, and de-blocking said link by the one node in response to receipt of a reconfigured message from the first-mentioned adjacent node.
