| 摘 要： | 对于多遥感器卫星系统,由于其具有多数据源且数据源特性相差较大,应采用同步/异步混合多路复用方式。该文在分析了高级在轨系统中几种虚拟信道调度策略的基础上,针对同步和异步业务流占用物理信道比率这一关键问题,提出一种基于各用户的数据速率(实时数据)和剩余数据量(回放数据)的实时动态调度方案。分析及仿真表明,该方案保证了同步/异步业务流高效、公平的共用同一物理信道,满足了各种数据源对网络的服务质量要求。

| Abstract: | For multi-sensor satellite systems, owing to its multi-data source and large difference of data source characteristics ,synchronous /asynchronous mode hybrid multiplexer should be used.The paper analyzed several virtual channel scheduling strategys of the Advanced Orbiting Systems(AOS), for the key issues of synchronous flows and asynchronous traffic flows occupaying the physical channel rate, made a real-time dynamic scheduling program basing on each user's data rate(real-time data) and the remaining data ... |
