IEEE 802.1 Time-Sensitive Networking (TSN) provides transport of data packets with bounded low latency, low delay variation and zero congestion loss. TSN can also use redundant transmissions to make data loss due to malfunctioning equipment extremely rare. In order to provide these capabilities, TSN adds time synchronization, shaping and queuing mechanisms, packet replication and elimination, and resource management to Layer 2 bridges. The predecessor of TSN is Audio Video Bridging (AVB), which has been successfully deployed and is used today. AVB evolved into TSN in order to address an expanded scope of work, which includes automotive networks, industrial automation (Industry 4.0), 5G, and many other use cases. In order to define a common architecture, the TSN Task Group collaborates with the IETF Deterministic Networking Working Group, which focuses on Layer 3 routed segments providing similar features to TSN.
