The IESG has approved the following document: - 'Applicability of the Path Computation Element (PCE) to the Abstraction and Control of TE Networks (ACTN)' (draft-ietf-pce-applicability-actn-12.txt) as Informational RFC This document is the product of the Path Computation Element Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pce-applicability-actn/ Technical Summary Abstraction and Control of TE Networks (ACTN) refers to the set of virtual network (VN) operations needed to orchestrate, control and manage large-scale multi-domain 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. Working Group Summary The WG process has been smooth. At one stage, this work caught up with (or got ahead of) the core ACTN and it had to pause. But now RFCs 8453 and 8454 have been published, and advancing this work is appropriate. WG consensus was reasonable. Document Quality This is an Informational document, so implementation is moot. However, there are known to be implementations (product and research) that use the ACTN architecture and contain PCE as key component. Personnel Who is the Document Shepherd for this document?
