Abstract

   The ability to compute shortest constrained Traffic Engineering Label    Switched Paths (TE LSPs) in Multiprotocol Label Switching (MPLS) and    Generalized MPLS (GMPLS) networks across multiple domains has been    identified as a key requirement.  In this context, a domain is a    collection of network elements within a common sphere of address    management or path computational responsibility such as an Interior    Gateway Protocol (IGP) area or an Autonomous System (AS).  This    document specifies a representation and encoding of a domain    sequence, which is defined as an ordered sequence of domains    traversed to reach the destination domain to be used by Path    Computation Elements (PCEs) to compute inter-domain constrained    shortest paths across a predetermined sequence of domains.  This    document also defines new subobjects to be used to encode domain    identifiers.
