There are many scenarios in which Traffic Engineering (TE) metrics
such as cost, latency and latency variation associated with a
Forwarding Adjacency (FA) or Routing Adjacency (RA) Label Switched
Path (LSP) are not available to the ingress and egress nodes. This
draft provides extensions for the Resource ReserVation Protocol-
Traffic Engineering (RSVP-TE) for the support of the discovery of
cost, latency and latency variation of an LSP.
