OSPF-Traffic Engineering Link Availability Extension for Links with
Variable Discrete Bandwidth
draft-ietf-ccamp-ospf-availability-extension-12.txt
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.
