Burst-Aware Mixed Flow Scheduling in Time-Sensitive Networks for Power Business

As power grid become more intelligent, it is critical to ensure efficient scheduling of all types of traffic to maintain system security and stability. Unexpected traffic generated by unforeseen events can also impact the normal operation of the network. Time-sensitive networks (TSN), which are deterministic network technologies, provide various traffic scheduling mechanisms that ensure the safe transmission of critical traffic. To address the challenges posed by bursty flows, we propose a hybrid traffic delivery mechanism that efficiently schedules bursty flows. This mechanism allocates a portion of bandwidth to the ATS mechanism, while scheduling time-sensitive flows and common bandwidth flows separately using the gated list of the TAS mechanism and the mapped time slot adjustment of the CQF mechanism. Our experiments demonstrate that the proposed BASM mechanism can schedule more flows with the same parameter settings than other mechanisms discussed in this paper, and can efficiently schedule burst flows with a success rate of over 94%. As a result, our mechanism enables efficient scheduling of mixed flows that include bursty flows.
