  2. Time-Sensitive NetworkingTask Group IEEE 802.1Q 2 • Charter • “provide the specifications that will allow time-synchronized low latency streaming services through 802 networks” • Main areas of development • Time synchronization • Queuing for time-sensitive streams • Resource and path reservation for time-sensitive streams

  3. TSN Projects IEEE 802.1Q 3 • IEEE 802.1AS-2011 (time synchronization based on IEEE 1588-2008) • IEEE 802.11v-2011 (time measurement services for WiFi, a small part of this project) • IEEE 802.3bf-2011 (time measurement services for Ethernet) • 802.1ASbt – revision - in process • IEEE 802.1Qat-2010 (stream reservation protocol) • 802.1Qcc – revision - in process • IEEE 802.1Qav-2010 (credit-based shaper) • 802.1Qbu – preemption - in process • 802.1Qbv – time-aware queuing - in process • IEEE 802.1BA-2011 (AVB systems)
