Multiprotocol Label Switching (MPLS)
Tunneling protocols encapsulate packets of a different protocol as the payload of a larger frame for delivery within networks utilizing the encapsulating protocol. Tunneling facilitates the delivery of payload over an incompatible delivery network and creates a secure path through an untrusted network. Protocols that this chapter describes include MPLS, Decap Groups, and Nexthop Groups.
