| Summary: | In order to solve the problem of hybrid scheduling of multiple time-sensitive flows in time-sensitive network(TSN), a TSN joint routing and hybrid traffic scheduling algorithm based on time-aware and cyclic queued forwarding was proposed. The TACQF hybrid traffic scheduling model was designed by combining TAS and CQF shapers. The model realized the simultaneous opening of TAS queue and CQF queue through cycle selection, and used the dead time of CQF queue to open TAS queue, so as to achieve soft isolation between different flows, and reduce conflicts between TT and AVB flows. JR-TACQF hybrid traffic scheduling algorithm was designed according to TACQF hybrid traffic scheduling model. The algorithm combined routes for scheduling and load balancing, thus improving bandwidth utilization and scheduling success rate. The simulation results show that the JR-TACQF hybrid traffic scheduling algorithm can effectively solve the TSN hybrid traffic scheduling problem, improve the scheduling success rate and bandwidth utilization rate, and generate feasible scheduling result in a low execution time. |
