Dear PCE Working Group, Please find an updated version of draft-ietf-pce-stateful-hpce. Updates to the I-D include:
- Clarification of stateful deployment scenarios and use cases - Terminology clean-up - Reference clean-up and proper assignment into normative and informative - Cleaner procedure numbering This version also addresses review comments from Hoamian and Adrian, I will follow-up specifically in separate emails later. BR, Dan and the draft-ietf-pce-stateful-hpce authors. -----Original Message----- From: I-D-Announce <[email protected]> On Behalf Of [email protected] Sent: 06 June 2019 19:56 To: [email protected] Cc: [email protected] Subject: I-D Action: draft-ietf-pce-stateful-hpce-08.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG of the IETF. Title : Hierarchical Stateful Path Computation Element (PCE). Authors : Dhruv Dhody Young Lee Daniele Ceccarelli Jongyoon Shin Daniel King Oscar Gonzalez de Dios Filename : draft-ietf-pce-stateful-hpce-08.txt Pages : 22 Date : 2019-06-06 Abstract: A Stateful Path Computation Element (PCE) maintains information on the current network state, including: computed Label Switched Path (LSPs), reserved resources within the network, and pending path computation requests. This information may then be considered when computing new traffic engineered LSPs, and for associated and dependent LSPs, received from Path Computation Clients (PCCs). Initialize the result of path computation from PCE is also helpful for the PCC to gracefully establish the computed LSP. The Hierarchical Path Computation Element (H-PCE) architecture, provides an architecture to allow the optimum sequence of inter-connected domains to be selected, and network policy to be applied if applicable, via the use of a hierarchical relationship between PCEs. Combining the capabilities of Stateful PCE and the Hierarchical PCE would be advantageous. This document describes general considerations and use cases for the deployment of Stateful, and not Stateless, PCEs using the Hierarchical PCE architecture.
