         Ethernet Traffic Parameters with Availability Information  
           draft-ietf-ccamp-rsvp-te-bandwidth-availability-07.txt 

Abstract 

   A Packet switching network may contain links with variable bandwidth, 
   e.g., copper, radio, etc. The bandwidth of such links is sensitive 
   to external environment. Availability is typically used for 
   describing the link during network planning. This document 
   introduces an optional Availability TLV in Resource ReSerVation 
   Protocol - Traffic Engineer (RSVP-TE) signaling. This extension can 
   be used to set up a Label Switched Path (LSP) in a Packet Switched 
   Network (PSN) that contains links with discretely variable 
   bandwidth.
