        RSVP-TE Signaling Extension for Links with Variable Discrete

Abstract 

   Packet switching network MAY contain 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 
   links with discretely variable bandwidth by introducing an Extended 
   Ethernet Bandwidth Profile TLV and an OPTIONAL Availability sub_TLV 
   in RSVP-TE signaling.
