According to TSN (Time-Sensitive Networking) standards, the recommended guidelines for guard bands between time slots in Qbv (quality of service-based scheduling) is an offset of at least 2 TSN frames. This guidance is based on the length of TSN frames and their respective transmission intervals. Having a minimum balance of two TSN frames ensures no conflicts arise because TSN frames overlap when transmitted from different traffic classes. As such, it provides a reliable mechanism for preventing data loss or corruption during time-sensitive communication operations. Furthermore, by having this guard band in place, TSN networks can provide a higher quality level of latency control and Quality of Service (QoS). This is because TSN frames transmitted in the same time slot will not interfere with each other and cause delays. Thus, guard bands are essential for TSN networks to ensure reliability and high performance.
Another essential factor to consider when implementing guard bands is the TSN frame size. You need to ensures that TSN frames have sufficient room to be transmitted without interference and allows TSN networks to reduce latency and provide a higher quality of service for time-sensitive communication operations. Furthermore, guard bands also help TSN networks avoid congestion as TSN traffic is distributed across multiple time slots, which reduces contention for resources. Following TSN standards when configuring guard bands is essential to ensure reliable and high-performance communications over TSN networks.
