Liaisons referring to this one Response to your liaison on Metro Compute Networking Architecture
Dear Colleagues,

The Broadband Forum is developing an architecture, functional modules, and
interface definitions for Metro Compute Networking to outline new cloud-based
broadband networks that connect isolated edge sites as one cloud to serve edge
computing services.

In the Broadband Forum meeting of 13th of December, 2022, an introduction to
ongoing IETF work in the areas of service routing and compute-awareness was
provided. It was agreed that BBF WT-491 will need suitable solutions for
service routing that can be incorporated as protocol recommendations into
realizations of BBF WT-491. Given our interest in these ongoing activities and
drafts, participants will work within the IETF according to IETF processes, to
help progress relevant work in this area. Please keep us apprised of progress
of these activities and the associated drafts.

Further, we would like to inform you that our SDN/NFV Work Area is continuing
to develop the interface definitions for Metro Compute Networking. Once the
architecture and functional descriptions reach a level of maturity, we plan to
share these with the IETF for review and comment.  Comments from the IETF may
be made via a liaison or BBF members may comment directly.

Enclosed to this liaison you can find the BBF TR-466 that reports the use cases
and the high level requirements for the Metro Compute Networking.

Please see below for information on our next meetings.

Lincoln Lavoie,
Broadband Forum Technical Committee Chair
