     Abstract 

     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 an LSP.
