| 摘 要： | 卫星信号通过数据接收站传送到地面网络再分发给不同的用户。数据接收站将承担陆地观测卫星的接收任务,并继续承担国外相关卫星的接收、处理与分发的任务。延时长信道的传输速率受限降低了TCP协议拥塞控制和流量恢复策略的性能。主要讨论了卫星数据接收站采用组播的方式与数据存储或其他数据管理分系统互连,并通过TCP/IP协议与中心站互通。

| Abstract: | The satellite signals are transmitted to the ground network via the data receiving station, and then distributed to different users. The data receiving station receives the data from land observation satellite, and still receives, processes and distributes the data of relevant satellites of foreign countries. The limited transmission rate of long delay channel degrades the performance of TCP protocol congestion control and traffic recovery policy. The paper discusses the interconnection of satellite data receiving station with data storage or other data management subsystems through multicast mode as well as the interworking with central station through TCP/IP protocol. |
