TSN Switch Features

IEEE 802.1Qbv
Time Aware Shaping

Provides guaranteed communication latency for time-critical traffic over standard Ethernet even in a converged infrastructure.

IEEE 802.1AS
Time Synchronization

Profile of IEEE 1588v2 for synchronization of clocks in the network. Supports timing requirements for scheduled TSN networks.

IEEE 802.1Qcc
SRP Enhancements

Defines the interfaces for central configuration of TSN networks. Supports configuration models for dynamic scheduling of TSN.

IEEE 802.1Qbu
Frame Preemption

Allows for optimal bandwidth utilization of non-scheduled background traffic sent in parallel with scheduled traffic.

IEEE 802.1CB
Seamless Redundancy

Enables seamless redundancy for increased network availability. Allows for redundancy on a per stream basis for individual critical streams.

IEEE 802.1Qci
Filtering and Policing

Protects against faulty and/or malicious endpoints and switches. Isolates faults to specific regions in the network. (Available 2021)
