摘　　要：提出了一种基于时间触发的光纤通道网络数据交换调度算法,在基于端口序号进行轮询调度(vp-RRM)算法的基础上增加了流量自适应机制。该算法对光纤通道网络中的传输数据按TT、RC、BE等业务类型分队列缓存,将队列长度与交换调度的优先级建立关联,可明显改善非均匀业务流的交换调度效率。经仿真及实验验证,该算法吞吐量性能在非均匀业务流下较vp-RRM明显提升,更加适用于TTFC网络的事件触发业务的交换调度。In this paper,a data exchange scheduling algorithm based on time trigger fibre channel network is proposed.Based on variable-length priority round Robin matching(vp-RRM),a traffic adaptive mechanism is added.The algorithm queues and caches the transmission data in the fibre channel network according to the service types such as time trigger(TT),rate-constrained(RC)and best-effort(BE),and correlates the queue length with the priority of switching scheduling,which can significantly improve the switching scheduling efficiency of non-uniform service flow.Through simulation and experimental verification,the throughput performance of the algorithm is significantly improved compared with VP-RRM under non-uniform traffic flow,and it is more suitable for the exchange scheduling of event triggered services in time trigger fiber channel(TTFC)network.
