摘要

基于internet的应用的快速增长推动宽带卫星网络承载IP流量。在先前提出的卫星网络无连接路由方案中，用于计算路径的度量并不能反映数据包可能经历的总延迟。本文提出了一种新的卫星分组路由协议(SGRP)。它根据中地球轨道(MEO)卫星在每个快照周期内的足迹面积，将低地球轨道(LEO)卫星分组。MEO卫星管理者根据LEO卫星发送的时延报告，计算出LEO成员的最小时延路径。详细介绍了快照和群决策方法，并通过仿真和分析对SGRP的性能进行了评价。

Satellite grouping and routing protocol for LEO/MEO satellite IP networks

The rapid growth of Internet-based applications pushes broadband satellite networks to carry on IP traffic. In previously proposed connectionless routing schemes in satellite networks, the metrics used to calculate the paths do not reflect the total delay a packet may experience. In this paper, a new Satellite Grouping and Routing Protocol (SGRP) is developed. It divides Low Earth Orbit (LEO) satellites into groups according to the the footprint area of the Medium Earth Orbit (MEO) satellites in each snapshot period. Based on the delay reports sent by LEO satellites, MEO satellite managers compute the minimum-delay paths for their LEO members. The snapshot and group decision method is detailed, the performance of SGRP is evaluated through simulations and analysis.
