Note Well

Any submission to the IETF intended by the Contributor for publication as all or part of an IETF Internet-Draft or RFC and any statement made within the context of an IETF activity is considered an "IETF Contribution". Such statements include oral statements in IETF sessions, as well as written and electronic communications made at any time or place, which are addressed to:

  • The IETF plenary session
  • The IESG, or any member thereof on behalf of the IESG
  • Any IETF mailing list, including the IETF list itself, any working group or design team list, or any other list functioning under IETF auspices
  • Any IETF working group or portion thereof
  • Any Birds of a Feather (BOF) session
  • The IAB or any member thereof on behalf of the IAB
  • The RFC Editor or the Internet-Drafts function

All IETF Contributions are subject to the rules of RFC 5378 and RFC 3979 (updated by RFC 4879).

Statements made outside of an IETF session, mailing list or other function, that are clearly not intended to be input to an IETF activity, group or function, are not IETF Contributions in the context of this notice.  Please consult RFC 5378 and RFC 3979 for details.

A participant in any IETF activity is deemed to accept all IETF rules of process, as documented in Best Current Practices RFCs and IESG Statements.

A participant in any IETF activity acknowledges that written, audio and video records of meetings may be made and may be available to the public.

bof objectives
BoF Objectives
  • Scope of SDN work within IETF
    • In scope
    • Out of scope
    • SDN vs SDN
      • Name change?
  • Gaps, existing solutions
  • Potential WG deliverables
  • Relationship with other groups
framing the discussion shamelessly stolen from l2vpn
Framing the Discussion(shamelessly stolen from L2VPN)
  • What is the problem?
    • Is the problem statement a good starting point?
  • What new work has to be done?
    • By “work” we don’t just mean create protocols
  • Do we agree IETF needs to work on this?
    • Not discussing which WG here and now!
  • Are we looking at a bottom-upor top-down problem?
    • xVPN up, or Net app down
where does sdn fit in
Where does SDN fit in?

sdn vs sdn
  • This is confusing
    • Name change is a good idea
  • Defined
    • Software/applications and interfaces whose sole purpose is to control a network's data plane
  • Driven
    • A software/applications interface for providing a network's control plane with the data plane (service) requirements and for receiving feedback on the service/treatment being delivered
