Method and apparatus for managing a transition for a class of data between first and second topologies in a data communications network

摘要

A method is disclosed of managing a transition for a class of data between first and second topologies in a data communications network comprising a plurality of nodes and supporting multiple topologies. The method comprises the steps, performed at a participating node, of defining a transition topology, marking data in said class as assigned to the transition topology; and forwarding marked data only among nodes within said transition topology.
