METHOD AND APPARATUS FOR ENABLING ROUTING OF LABEL SWITCHED DATA PACKETS

摘要

A method of enabling routing of label switched data packets (202) in a data communications network (103) comprising a plurality of nodes (R2-R5) and supporting multiple topologies (200), is performed at an enabling node and comprises constructing a per-topology label forwarding table (200) and a packet routing apparatus (R2) for an MPLS packet-witched network (103) are disclosed to implement and perform the method.
