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.
