Applicability of the Path Computation Element to the Abstraction and Control of TE Networks

Overview

RFC 8637, “Applicability of the Path Computation Element to the Abstraction and Control of TE Networks”, is an Informational document published in July 2019 by D. Dhody, Y. Lee, D. Ceccarelli. The canonical text is published by the RFC Editor.

Abstract

Abstraction and Control of TE Networks (ACTN) refers to the set of virtual network (VN) operations needed to orchestrate, control, and manage large-scale multidomain TE networks so as to facilitate network programmability, automation, efficient resource sharing, and end-to-end virtual service-aware connectivity and network function virtualization services.

The Path Computation Element (PCE) is a component, application, or network node that is capable of computing a network path or route based on a network graph and applying computational constraints. The PCE serves requests from Path Computation Clients (PCCs) that communicate with it over a local API or using the Path Computation Element Communication Protocol (PCEP).

This document examines the applicability of PCE to the ACTN framework.
