Abstract
The ability to compute shortest constrained Traffic Engineering LabelSwitched Paths (TE LSPs) in Multiprotocol Label Switching (MPLS) andGeneralized MPLS (GMPLS) networks across multiple domains has beenidentified as a key requirement. In this context, a domain is acollection of network elements within a common sphere of addressmanagement or path computational responsibility such as an InteriorGateway Protocol (IGP) area or an Autonomous System (AS). Thisdocument specifies a representation and encoding of a domainsequence, which is defined as an ordered sequence of domainstraversed to reach the destination domain to be used by PathComputation Elements (PCEs) to compute inter-domain constrainedshortest paths across a predetermined sequence of domains. Thisdocument also defines new subobjects to be used to encode domainidentifiers.
