Abstract Abstract
A Packet switching network may contain links with variable bandwidth, A Packet switching network may contain links with variable bandwidth,
e.g., copper, radio, etc. The bandwidth of such links is sensitive e.g., copper, radio, etc. The bandwidth of such links is sensitive
to external environment. Availability is typically used for to external environment. Availability is typically used for
describing the link during network planning. This document describing the link during network planning. This document
introduces an optional Availability TLV in Resource ReSerVation introduces an optional Availability TLV in Resource ReSerVation
