FYI.
This is related to control of Service Function Path establishment
The relevant draft in PCE is draft-wu-pce-traffic-steering-sfc<http://tools.ietf.org/id/draft-wu-pce-traffic-steering-sfc-06.txt>.

Minutes of the SFC Control Plane side meeting
March 25, 8am-9am

Participants:
Joel Halpern, Jim Guichard, Paul Quinn, Andy Malis, Walter Haeffner, Mohamed Boucadair, Qin Wu, James Huang, Seungik Lee, and Linda Dunbar

Agreed:
SFC WG needs to document the overall interfaces for controlling service function path.
Agreed the following interfaces for control plane.

SFC  Control Plane  Architecture

The SFC control plane architecture will specify the interfaces for

-          Classifier

-          SFF

-          Service functions (and SF proxy)
And will specify the content to be exchanged over each interface for controlling Service Function Path establishment and alternation due to SFC policy change or SF/network failures.

We are looking for comments from the community with regard to this proposed SFC control plane architecture.

Agreed that IETF 93 Prague meeting will allocate a dedicated slot for control plane discussion.

Cheers,

Linda Dunbar
