ABSTRACT:
A router comprises an interface for receiving packets, wherein the packets include Multiprotocol Label Switching (MPLS) labels having the same label value that corresponds to an MPLS label switched path (LSP), and wherein each of the MPLS packets includes MPLS experimental (EXP) bits defined to identify a class of service to which the respective packet belongs. The router is a transit router along the MPLS LSP, and further includes a control unit that, for each of the packets, accesses forwarding information to determine whether to forward the packet along the LSP or to redirect the packet along a second LSP based on the classes of service specified in the EXP bits. The router receives policies via a user interface, and applies the policies to index into the forwarding information to select a forwarding entry, wherein the index is responsive to the label value in combination with the EXP bits.
