IP-based Tool Requirements for MPLS Networks

IP-based Tool Requirements for MPLS Networks

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.

3
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 Daves 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
