| 摘 要： | 在地震灾害发生后,地震应急卫星通信网为地震救援提供高效可靠的音视频以及数据传输信道。由于地震灾害的突发性和不可预见性,地震应急卫星通信网在满足业务传输需求的同时需要实现灵活组网。OSPF(Open Shortest Path First,优先开放最短路由协议)较小的网络开销以及兼具灵活的组网方式,对于带宽资源有限的卫星通信系统来说无疑是相当具有优势的。本文着重研究了OSPF在地震应急卫星通信网中的具体应用。

| Abstract: | Earthquake Emergency Satellite Communication Network provides satellite communication channels for audio,radio and other data transmissions after earthquake occurrence.The network should be flexible because of the abruptness and unpredictability of earthquake emergency.OSPF （Open Shortest Path First） has less traffic and flexible networking; it has advantage especially for satellite links which only have limited bandwidth.This article focuses on the application of OSPF in EESCN. |
