RELY-TSN-LAB is a new concept of intelligent device that integrates IEEE IEEE 802.1AS sub-microsecond
synchronization for analysing the behaviour of a network segment under certain stress condition.

• RELY-TSN-LAB can simulate surges conditions and other interferences In the network by forcing FCS (CRC) errors in selected frames. Last bit of the check sequence is changed leaving the rest of the frame
untouched.

• Additionally, the device permits the measurement of the bandwidth and latency of a certain traffic in a
specific device or network segment. This feature is performed by hardware timestamping the packet
before it is injected in the network or device under analyse and after receiving it from the network or DUT.

• The timestamp of the packets is based on the IEEE 802.1AS synchronization, which becomes an
important benefit when used in Deterministic networking.

• The timestamps can be stored along with useful package information that can be post-processed in order to generate performance results about IEEE 802.1Qbv.

• Additionally, an embedded web manager tool together with a Linux based OS simplifies the configuration, the creation of filters and the customization of the tool, to the specific requirement of any customer.
