摘要： 在分包遥测中建立了传送层入口处源包的长度模型 ,分析了不同帧长度和包长对比关系下对帧形成时间分布的影响 ,以及帧效率和帧等待时间之间的关系问题。获得的结果可为包装层各应用过程源包长度的确定以及传送层数据流的分析和数据延时分析提供参考。

Abstract: Two models of packet length are developed at the entrance of transfer layer in packet telemetry.The distribution of framing time is analyzed for different ratio of frame length to packet length.And the relationship between frame efficiency and frame waiting time is also analyzed.These results might help to analyze data stream and data delay in transfer layer,and determine the proper packet length to achieve high system performance.
