Abstract
A stateful Path Computation Element (PCE) maintains information about Label Switched Path (LSP) characteristics and resource usage within a network in order to provide traffic engineering calculations for its associated Path Computation Clients (PCCs). This document describes general considerations for a stateful PCE deployment and examines its applicability and benefits through a number of use cases. Path Computation Element Protocol (PCEP) extensions required for stateful PCE usage are covered in separate documents.
