Requirements for MPLS OAM in transport networks

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

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

Status and contributors

• No draft published yet – work in progress– Plan to submit first version in time for Dublin
