The Time-Sensitive Networking (TSN) Task Group (TG) is a part of the IEEE 802.1 Working Group (WG). For general information, see the IEEE 802.1 home page.
The charter of the TSN TG is to provide deterministic services through IEEE 802 networks, i.e., guaranteed packet transport with bounded latency, low packet delay variation, and low packet loss. The TSN TG has been evolved from the former IEEE 802.1 Audio Video Bridging (AVB) TG. The TSN TG includes the former IEEE 802.1 Interworking TG. The original work on AVB was done as part of the "Residential Ethernet Study Group" of IEEE 802.3.
Published TSN standards and ongoing TSN projects are listed below. Archived and withdrawn projects are available in the archives.
The TSN standards can be applied in many verticals. Some of them are listed in the application of TSN page.
The papers in the TSN feature topic of the June 2018 Issue of IEEE Communications Standards Magazine, an overview paper, and an introductory presentation may be good to get started.
Meetings and conference calls are open and conducted on individual basis.
Agendas and minutes are publicly accessible.
IEEE Std 802.1CB-2017: IEEE Standard for Local and Metropolitan Area Networks — Frame Replication and Elimination for Reliability.
IEEE Std 802.1AS-2011: IEEE Standard for Local and Metropolitan Area Networks — Timing and Synchronization for Time-Sensitive Applications in Bridged Local Area Networks. It provides a Layer 2 time synchronizing service that is appropriate for the most stringent requirements of consumer electronics applications. This was done in cooperation with the IEEE 1588 working group, and so the point-to-point 802.3 sublayer of 802.1AS is a specific profile of IEEE Std 1588-2008. See also IEEE 802.1AS-2011/Cor1-2013 and IEEE 802.1AS-2011/Cor1-2015. Note the ongoing P802.1AS-REV project.
IEEE Std 802.1Qat-2010: IEEE Standard for Local and Metropolitan Area Networks — Virtual Bridged Local Area Networks – Amendment 14: Stream Reservation Protocol (SRP). (It is part of IEEE Std 802.1Q-2018.) Note IEEE Std 802.1Qcc, which specifies enhancements to SRP.
IEEE Std 802.1BA-2011: Standard for Local and Metropolitan Area Networks: Audio Video Bridging (AVB) Systems. It specifies a set of usage-specific profiles to help interoperability between networked devices using the AVB specifications. See also IEEE 802.1BA-2011/Cor1-2016.
Note that project IDs are sequentially increasing double letters. Capital letters are used for stand alone documents, e.g., P802.1CS. Lower case letters are used for amendments, e.g., cw in case of P802.1Qcw (capital letter indicates the base standard being amended, e.g., 802.1Q). P upfront of the ID indicates project as opposed to published standards without P.
The TSN TG meets at the IEEE 802 Plenary meetings and at the Interim meetings of the IEEE 802.1 WG. Conference calls are held weekly, see upcoming calls and conference call details.
Proposed agendas are announced in advance on the IEEE 802.1 email list (you can subscribe here).
All meeting and conference call attendees are expected to review the IEEE-SA patent policy prior to participating, and to act accordingly.
Please contact János Farkas, the Chair of the TSN TG if you have comments to the TSN TG page.
