| 摘 要： | 文章提出了带有优先级的最短时延卫星路由策略，将业务分为话音业务和数据业务，根据业务时延要求的不同，优先处理话音业务，再根据源卫星、目的卫星的位置，计算路径延时的度量标准，以此得到经过优劣排序的候选路径集合，并对最佳路径进行计算。仿真结果表明，算法显著降低了话音业务的时延水平，有效提高通话质量。

| Abstract: | The paper proposes a least time-delay routing algorithm with priority, Voice and data service are both taken into account, and voice service is preferential. Then measure mettle Of path delay to carry out calculation for best path based on positions of source and objective satellite, and get a candidate path collection by good and inferior sorting. The simulation results indicate that the algorithm can reduce the time-delay of voice service obviously, and improve the call quality effectively. |
