Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) may be established using the Resource Reservation Protocol Traffic Engineering extensions (RSVP-TE). This protocol includes an object (the SESSION_ATTRIBUTE object) which carries a flags field used to indicate options and attributes of the LSP. That flags field has eight bits allowing for eight options to be set. Recent proposals in many documents that extend RSVP-TE for signaling additional features and function for MPLS LSPs have suggested uses for each of the previously unused bits. This document defines a new object for RSVP-TE messages that allows the signaling of further attribute bits and also the carriage of arbitrary attribute parameters. This makes RSVP-TE easily extensible to support new requirements.
