Abstract 

   Packet switching network usually contains links with variable 
   bandwidth, e.g., copper, radio, etc. The bandwidth of such link is 
   sensitive to external environment. Availability is typically used 
   for describing the link during network planning. This document 
   describes an extension for RSVP-TE signaling for setting up a label 
   switching path (LSP) in a Packet Switched Network (PSN) network 
   which contains variable bandwidth link by introducing an optional 
   availability field in RSVP-TE signaling.
