METHOD FOR CONTROLLING SESSIONS ACCORDING TO A ROUTING PROTOCOL

摘要

In a network (20) for transmitting packets, which is based on a routing protocol and comprises a router (110) having at least two sessions (25, 26) according to the protocol, which are established with at least two control routers (21, 22), the sessions are redundant and enable routing and/or connectivity information indicating paths for transmitting packets over the network to be transmitted and updated. When the loss of a session has been detected, if the router still has an established session, the router updates the routing and/or connectivity information on the basis of the established session, and routes the packets according to the information. If the router no longer has any established sessions, it routes the packets according to the last information it has updated.
