Domain Subobjects for the Path Computation Element Communication Protocol
RFC 7897, “Domain Subobjects for the Path Computation Element Communication Protocol”, is an Experimental document published in June 2016 by D. Dhody, U. Palle, R. Casellas. The canonical text is published by the RFC Editor.
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.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
