Abstract

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.

A method for reconfiguring a ring network comprising a plurality of nodes connected by a plurality of links to form said network, the method comprising, at one of said nodes:

initiating reconfiguring of said one node in response to receipt of a network change message, NCM, received from an adjacent node;
blocking the link over which the NCM was received;
sending an NCM to the other adjacent node;
reconfiguring address information in said one node by at least partially flushing address information in said one node;
flushing any old queued messages from said one node;
transmitting a reconfigured message, RM, to said other adjacent node in response to completion of said flushing any old queued messages;
and
de-blocking said link in response to a RM received from said adjacent node.
