In certain networking topologies, it may be advantageous to maintain
associations between endpoints and key transit points to support an
instance of a service. Such associations are known as Calls.
A Call does not provide the actual connectivity for transmitting user
traffic, but only builds a relationship by which subsequent
Connections may be made. In Generalized MPLS (GMPLS) such Connections
are known as Label Switched Paths (LSPs).
This document specifies how GMPLS Resource Reservation Protocol -
Traffic Engineering (RSVP-TE) signaling may be used and
extended to support Calls. These mechanisms provide full and logical
Call/Connection separation.
The mechanisms proposed in this document are applicable to any
environment (including multi-area), and for any type of interface:
packet, layer-2, time-division multiplexed, lambda, or fiber
switching. [STANDARDS TRACK]
