摘要
航空航天电子系统对信息交互网络的性能要求越来越高,提高航空航天电子系统总线带宽、增大允许接入终端数量、降低时延提升实时性是空天电子领域重要的研究方向之一。针对无源光网络PON结构下FC-AE-1553总线中存在的下行"一点对多点"的调度和上行"多点对一点"的信道共享冲突问题,设计了一种支持多业务QoS要求的网络带宽动态分配机制。仿真结果表明,该带宽分配机制在高速网络吞吐量376Gbps的条件下可保证很低的多业务传输时延<50μs。
With the increasing demanding of the utilization of network bandwidth resources of avionics systems,the research field focusing on improving transmission rate and bandwidth of avionics buses and increasing the number of terminals and real-time performance have attracted great attentions. In this paper,a multi-service QoS supported dynamic bandwidth allocation mechanism based on concurrency for FC-AE-1553 PON network has been proposed. The simulation results show that this mechanism meets multi-service delay requirement（〈50μs） and the maximum throughput is 3. 76 Gbps.
