Generalized Multiprotocol Label Switching (GMPLS) can be used to control a wide variety of technologies. In some of these technologies@ network elements and links may impose additional routing constraints such as asymmetric switch connectivity@ non-local label assignment@ and label range limitations on links. This document provides efficient@ protocol-agnostic encodings for general information elements representing connectivity and label constraints as well as label availability. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.
