Optimized L2/L3 services over classical MPLS transport

Abstract:

Systems and methods in a node in an MPLS network include determining a plurality of services supported at the node; determining a bitmask to represent the plurality of services supported at the node, wherein the bitmask includes a starting service and each subsequent bit representing another service of the plurality of services and with each bit in the bitmask set based on the plurality of services supported at the node; and transmitting an advertisement to other nodes in the network with the bitmask based on the plurality of services supported at the node. The steps can further include transmitting a packet associated with a service of the plurality of services with an MPLS label stack including one or more transport labels for a destination of the packet, a service label identifying the service, and a source label identifying a source Internet Protocol (IP) address of the packet.
