Motivation• Providers have been coming to us with OAM

requirements that differed from those that were available.• There was a concern that current requirements did

not reflect real operational environments.• Disparately located requirements for MPLS-

related OAM scattered about.• Makes it difficult for those writing drafts to find all of

the requirements.• It is a good idea to put these together in one place.

Motivation (cont)• Requirements gathered from a diverse set of MPLS

operators and their research departments.• Requirements consider both current operational requirements

as well as future ones based on real deployments.• Providers want evolutionary approaches NOT

revolutionary ones.• Sensitive to both OPEX and CAPEX.• These approaches are suitable for existing MPLS

technologies. • We do not want to reset current protocols; we want to evolve

them.

Recommendations

• Clarify draft based on comments.• Cull out requirements from Dave’s OAM Framework

draft. • Deliver combined draft by March IETF Meeting.

• Accept this combined document as an MPLS WG document.• Addresses operations and management requirement in

charter.• Gives direction to future OAM solutions/tools.• Keep requirements for MPLS OAM tools and solutions for

not only MPLS, but PWE3 and PPVPN MPLS
