Technical Summary

 This document specifies a standard representation and encoding of an ordered sequence of domains in Path Computation Element Protocol (PCEP).  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).  The domain sequence is used by a Path Computation Client (PCC) to stipulate a pre-determined sequence of domains that a path must traverse.  It is also used by a Path Computation Element (PCE) to inform a PCC of a sequence of domains that a path must traverse, without giving full details of the sub-paths within those domains.

Working Group Summary

  There were no particular points of contention in the WG process.  The consensus behind publication of this document as an Experimental RFC appears solid.

Document Quality

 There are two existing implementations of this draft.  The document has been well reviewed by the PCEP working group, as reflected in the Acknowledgements section.  In particular, Adrian Farrel did a thorough review and provided substantial comments, which were all addressed.
