Layer Independent OAM Management in the Multi-Layer Environment (lime)

LIME OAM Model Design Team

The IETF LIME WG is chartered to develop:

  • YANG data model(s) for generic layer-independent and technology-independent configuration, reporting and presentation for OAM mechanisms.
  • An architecture for OAM that can be used as guidance by other IETF working groups developing new OAM protocols or modifying existing OAM protocols, at any layer and for any technology. This guidance will cover both the management and data planes. Existing OAM architectures will be reviewed.
  • Applicability document: The YANG model(s) specified in this working group must be usable and extensible by the existing OAM technologies. This usability and extensibility must be demonstrated, for example with IP Ping, traceroute, BFD, and LSP Ping. Note the technology-specific data model extensions should ideally be worked on in the respective working groups.

At our first WG meeting, several participants state that the OAM Model chosen by the WG could influence the WG's output. Therefore, a design team is being assembled to address the following questions:

  • To what degree does the choice of an OAM modes influence LIME work?
  • What are the candidate models (IEEE CFM? BFD? Other?)
  • Provide an overview of each?
  • Can LIME's work be made "model agnostic"?
  • If not, which model should we embrace?

The design team will deliver a single Internet Draft by IETF 92. The Internet Draft willinfluence subsequent LIME work, but may not be useful beyond the lifetime of the LIME WG. Therefore, the ID may never be submitted to the IESG for publication.

The design team will produce a monthly status report for the duration of the task.
