Requirements for MPLS OAM in Transport Networks: Insights from Alcatel-Lucent Experts

This document outlines the requirements for MPLS Operations, Administration, and Maintenance (OAM) in transport networks as discussed by experts Matthew Bocci and Italo Busi from Alcatel-Lucent. It emphasizes the need for MPLS applications in packet transport services with guaranteed SLAs and deterministic behavior. The draft seeks to translate ITU-T standards into IETF terminology and aims to establish a consensus on new OAM capabilities necessary for transport applications. Contributors are actively developing and plan to submit the initial draft soon.

  1. Requirements for MPLS OAM in transport networks Matthew Bocci (Alcatel-Lucent) Italo Busi (Alcatel-Lucent)

  2. Background • There exist applications for MPLS where: • MPLS is used for packet transport services • Aggregation/transport of all services in a common, client-agnostic manner • Strictly deterministic SLA guarantees and network behaviour • Operational characteristics differ from the way we have traditionally managed IP networks • Mechanisms to suit these applications described in draft-ietf-pwe3-mpls-transport-01.txt • ITU-T developed T-MPLS to address this

  3. Objectives • Bring requirements for MPLS OAM in transport applications into the IETF community • Requirements originated from transport applications, as per ITU-T supplement Y Suppl.4 (former G.8113 draft) • Translate ITU-T definitions into IETF language • Put in context of wider MPLS OAM topic • Identify new and/or overlapping requirements • Identify and get consensus on new OAM capabilities needed for transport applications

  4. Status and contributors • No draft published yet – work in progress • Plan to submit first version in time for Dublin • Current co-contributors: • Loa Anderson, Dinesh Mohan, Stewart Bryant, Dave Allan, Lieven Levrau, Huub van Helvoort, Marc Lasserre, Yuji Tochio • Please speak to one of us if you are interested
