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 Extended Ethernet Bandwidth Profile TLV and an 
   OPTIONAL Availability sub-TLV in RSVP-TE signaling. This extension 
   can be used to set up a label switching path (LSP) in a Packet 
   Switched Network (PSN) that contains links with discretely variable 
   bandwidth.
