    OSPF-TE Link Availability Extension for Links with Variable Discrete

Abstract 

   A network may contain links with variable discrete bandwidth, e.g., 
   copper, radio, etc. The bandwidth of such links may change 
   discretely in reaction to changing external environment. 
   Availability is typically used for describing such links during 
   network planning. This document defines a new type of the 
   Generalized Switching Capability-specific information (SCSI) TLV to 
   extend the Generalized Multi-Protocol Label Switching (GMPLS) Open 
   Shortest Path First (OSPF) routing protocol. The extension can be 
   used for route computation in a network that contains links with 
   variable discrete bandwidth. Note, this document only covers the 
   mechanisms by which the availability information is distributed. The 
   mechanisms by which availability information of a link is determined 
   and the use of the distributed information for route computation are 
   outside the scope of this document. It is intended that technology-
   specific documents will reference this document to describe specific 
   uses.
