Abstract
Described herein are methods and devices (e.g., routers) that add network services to a multiprotocol label switching (MPLS) network. A method can include a network device of the MPLS network receiving a packet, the network device of the MPLS network modifying the packet by adding multiple MPLS extension headers, wherein each of the multiple MPLS extension headers added to the packet is used to support a different one of multiple network services for the MPLS network, and the network device of the MPLS network forwarding the packet as modified to another network device of the MPLS network.
