The concept of a call set-up process, wherein resources are reserved before calls are established in a network, goes back to the signaling-theory days of telephony. This concept was adapted for data networking when QoS in IP network became an issue. RSVP has been designed by the IETF in 1997 for this very function. The protocol was designed to request required bandwidth and traffic conditions on a defined or explained path.
RSVP with features added to accommodate traffic engineering is one of the two protocols elected to design MPLS networks signaling (see RFC 3031 and RFC 3210). The so called RSVP-TE has been extended as the elected protocol for GMPLS networks signaling (see RFC 3473).
MARBEN RSVP-TE has been designed to provide the most simple interface that hides non- RSVP-TE protocol mechanisms to the user of the Networking Protocols stack. Indeed, MARBEN RSVP-TE fully handles:
MARBEN RSVP-TE service is intended to be generic and extensible enough to accommodate a set of different user’s profile, and future extensions to the RSVP-TE protocol. Such user's profiles are:
