TEAS Chairs 

I am a member of the TEAS WG and I am interested in joining the Network Slicing Design Team.  I have many years of experience as a network architect with Verizon and many designs involving all aspects of TE.

The objectives and deliverables for the design team have been updated based on public and private feedback and is enclosed. There are changes from what was previously announced in (https://mailarchive.ietf.org/arch/msg/teas/H3azyFI3kIaZDhxwEcSK1_O2CRA), notably calling out scope as being focused on TE technology as the basis for the DT’s work.

The aim of the DT remains to produce documents that will follow the normal working process, so all will be able to participate in and contribute to this work once we have a WG document as it progresses through normal WG processing.  We do note that the objective of the DT is to produce an initial draft and there is no requirement for document authorship to be limited to or include all DT members, and as usual, we expect a WG document to reflect actual contribution to the work.

Much of the IETF discussion has focused on how the combination of VPN and TE technologies can be used to deliver Network Slices. The TEAS Network Slicing Design Team (NSDT) is being formed to develop a framework for providing Network Slicing using IETF TE technologies. The expectation is for IETF technologies such as IP, MPLS and GMPLS, to  be used to create specific, isolated, and managed network instances. The use of such technology in networks and other SDOs is up to others; this work does not imply that the IETF specifies how slicing in any particular setting should be done.

> The primary goal of the design team is to determine how existing technologies can be used, but it is possible that some extensions to those technologies are needed. If such extensions relate to technology from another working group, any eventual work belongs to that group. The reuse of definitions and technologies developed by other SDOs is also in scope, although extensions to such will be done in the appropriate SDO. An important early deliverable to the working group from the design team will be a proposed refinement of what is in-scope and what is out-of-scope for the WG on this topic.

It will present an update on their status and plans at IETF 106 (Singapore) - which will hopefully include an initial discussion on scope.  For  IETF 107 (Vancouver) the goal for the design team is an initial design team framework, and possibly draft, in time for discussion at the meeting.  A stable draft is targeted for discussion at IETF 108. Note authorship of design team draft(s) will be based on contribution to the work, not membership in the design team. Once the draft is accepted as a working group document, it will progress per TEAS working group normal process.

Design team meetings will be announced on the list and open to all.  The specific workings, including meeting schedules, of the design team are the discretion of the team.
