Applicability of a Stateful Path Computation Element
RFC 8051, “Applicability of a Stateful Path Computation Element”, is an Informational document published in January 2017 by X. Zhang, I. Minei. The canonical text is published by the RFC Editor.
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, as well as its challenges and limitations, through a number of use cases. PCE Communication Protocol (PCEP) extensions required for stateful PCE usage are covered in separate documents.
