I appreciate that this is a request for a time commitment from some very busy people. In that vein, the invitees should feel free to delegate their attendance to parties who may have a particular interest. I’m attending meetings all week. Feel free to txt me at 1-925-980-6430 with questions or complaints. Email may work, also. — Norm Finn From: Glenn Parsons <[email protected]<mailto:[email protected]>> Date: Tuesday, July 22, 2014 at 04:04 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>>, Richard Barnes <[email protected]<mailto:[email protected]>>, Alissa Cooper <[email protected]<mailto:[email protected]>>, Alia Atlas <[email protected]<mailto:[email protected]>>, Adrian Farrel <[email protected]<mailto:[email protected]>>, Julien Meuric <[email protected]<mailto:[email protected]>>, JP Vasseur <[email protected]<mailto:[email protected]>>, "Alvaro Retana (aretana)" <[email protected]<mailto:[email protected]>>, Jeff Tantsura <[email protected]<mailto:[email protected]>>, Brian Haberman <[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>>, Pascal Thubert <[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>>, Karen O'Donoghue <[email protected]<mailto:[email protected]>>, Yaakov Stein <[email protected]<mailto:[email protected]>>, Spencer Dawkins <[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>>, David Black <[email protected]<mailto:[email protected]>>, Gorry Fairhurst <[email protected]<mailto:[email protected]>>, "James Polk (jmpolk)" <[email protected]<mailto:[email protected]>>, "Benoit Claise (bclaise)" <[email protected]<mailto:[email protected]>>, Joel Jaeggli <[email protected]<mailto:[email protected]>>, Mehmet Ersue <[email protected]<mailto:[email protected]>>, Bert Wijnen <[email protected]<mailto:[email protected]>> Cc: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [ieee-ietf-coord] Liaison from IEEE 802.1 - Deterministic Networking To: Richard Barnes <[email protected]<mailto:[email protected]>>; Alissa Cooper <[email protected]<mailto:[email protected]>>; Real-time Applications and Infrastructure Area Directors Alia Atlas <[email protected]<mailto:[email protected]>>; Adrian Farrel <[email protected]<mailto:[email protected]>>; Routing Area Directors Julien Meuric <[email protected]<mailto:[email protected]>>; JP Vasseur <[email protected]<mailto:[email protected]>>; Path Control Element WG chairs Alvaro Retana (aretana) <[email protected]<mailto:[email protected]>>; Jeff Tantsura <[email protected]<mailto:[email protected]>>; Routing Area WG chairs Brian Haberman <[email protected]<mailto:[email protected]>>; Ted Lemon <[email protected]<mailto:[email protected]>>; Internet Area Directors Pascal Thubert (pthubert) <[email protected]<mailto:[email protected]>>; Thomas Watteyne <[email protected]<mailto:[email protected]>>; IPv6 over TSCH WG chairs Ray Bellis <[email protected]<mailto:[email protected]>>; Mark Townsley <[email protected]<mailto:[email protected]>>; Home Networking WG chairs Karen O'Donoghue <[email protected]<mailto:[email protected]>>; Yaakov Stein <[email protected]<mailto:[email protected]>>; Tictoc WG chairs Spencer Dawkins <[email protected]<mailto:[email protected]>>; Martin Stiemerling <[email protected]<mailto:[email protected]>>; Transport Area Directors David Black <[email protected]<mailto:[email protected]>>; Gorry Fairhurst <[email protected]<mailto:[email protected]>>; James Polk (jmpolk) <[email protected]<mailto:[email protected]>>; Transport Area WG chairs Benoit Claise <[email protected]<mailto:[email protected]>>; Joel Jaeggli <[email protected]<mailto:[email protected]>>; Operation and Management Area Directors Mehmet Ersue <[email protected]<mailto:[email protected]>>; Bert Wijnen <[email protected]<mailto:[email protected]>> Network Configuration WG chairs At 8:00 PM on Wednesday, July 23, at IETF90 in Toronto, there will be a side meeting (aka Bar BOF — see RFC6771) on the subject of Deterministic Networking in the Quebec room. IEEE 802.1 wishes to encourage your cooperation and/or participation. Over the past few years, the IEEE 802 Audio Video Bridging Task Group and it successor, the Time-Sensitive Networking TG, have released standards that define: 1. Protocols for the reservation, by end stations, of Layer 2 network resources for critical flows; 2. Specific data plane mechanisms for a Layer 2 network to guarantee 0 congestion loss, and consequently, a known finite end-to-end latency, for those reserved flows; and 3. Plug-and-play distribution of the Precision Time Protocol (IEEE 1588 PTP) over bridged, routed, or mixed networks. These standards were originally targeted for the transport of raw audio and video streams. The successful deployment of multi-vendor networks employing these standards has triggered interest from new market segments, including industrial, vehicular, and other real-time systems. As a consequence, the IEEE 802.1 Time-Sensitive Networking Task Group has number of projects in progress to expand the first-round capabilities. This success has also made clear that the users of these capabilities have networking needs that transcend the limitations imposed by networks that operate at only Layer 2. The following elements are essential to expand the current Time-Sensitive Networking TG’s standards into “Deterministic Networking”: A. Deterministic Networking has to be a QoS feature of standard networks, not a set of point features around which one could write an Application. B. The networks of interest contain a mixture of bridges and routers. The QoS features have to be supported regardless of Layer 2 / Layer 3 boundaries. The control protocols must be visible to both routers and bridges; every box along the path must reserve resources. C. The host making the reservations must not care whether the first box to which it is connected is a bridge or a router, or what suite of protocols is used by the network to support its reservations. A number of members of IEEE 802.1 believe that the models for information propagation used by the Path Computation Element, RSVP, RSVP-TE, PCEP, and/or segment routing are a superset of that used by the existing and planned work by the 802.1 TSN WG, and offer a model for a combined Layer 2 / Layer 3, IEEE / IETF, effort. We hope that the Deterministic Networking side meeting can be used by the participants to test the waters, and see whether there is interest in working on the above problems. -- Glenn Parsons - Chair, IEEE 802.1 [email protected]<mailto:[email protected]> +1-613-963-8141
