     Abstract 

     There are many scenarios in which Traffic Engineering (TE) metrics 
     such as cost, delay and delay variation associated with the TE link 
     formed by 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) to 
     support automatic collection of cost, delay and delay variation 
     information for the TE link formed by a LSP.
