RSVP – Resource Reservation Protocol
Resource Reservation Protocol is a set of communication rules that allows connections or resources on the Internet to be reserved. RSVP is part of the Internet IntServ (Integrated Service) model, which ensures best effort service, real time service, and controlled link sharing. Although Intserv has not seen widespread use, an extension to RSVP which supports Traffic Engineering, termed RSVP-TE, is used widely in MPLS networks.
