有线无线融合的卫星时间敏感网络流调度数据集

本项目通过时间戳反馈机制能够保障网络不拥塞，通过动态时延控制调度算法调度数据包能够确定性保障TSN流在网络中传输，公平地调度其它类型数据包，可提升网络的整体吞吐量。将卫星内部数据包中的有线TSN帧映射到无线TDMA帧中；根据无线TDMA帧的目的MAC地址和QoS字段存储到缓存队列中；对TSN流中的数据包打上入队时间戳后入队进行入队管理；按照时间戳反馈机制将非TSN流的数据包进行入队管理；出队调度时判断当前时隙是否属于本卫星节点，若是则采用动态时延控制调度算法调度各类数据包。

This project leverages the timestamp feedback mechanism to avoid network congestion. By scheduling data packets with the dynamic delay control scheduling algorithm, it can deterministically guarantee the transmission of TSN flows over the network, fairly schedule other types of data packets, and enhance the overall network throughput. Specifically, wired TSN frames within intra-satellite data packets are mapped to wireless TDMA frames; these frames are stored in buffer queues based on the destination MAC address and QoS field of the wireless TDMA frames; enqueue timestamps are attached to data packets in TSN flows before enqueuing them for enqueue management; non-TSN flow data packets undergo enqueue management in line with the timestamp feedback mechanism. During dequeue scheduling, the system judges whether the current time slot belongs to the local satellite node. If so, the dynamic delay control scheduling algorithm is adopted to schedule all types of data packets.
