AI总结：
本文通过 CLEO 实验，研究在低地球轨道卫星上运行互联网协议（IP）路由器的可行性，展示了基于商用网络标准的空间互联网技术及其在灾害监测中的应用。
摘要：
2003年9月，低地球轨道上的思科路由器（CLEO）作为实验性次级有效载荷搭载在英国灾害监测星座（UK-DMC）卫星上发射升空。UK-DMC卫星是日益增多的在轨DMC卫星之一，这些卫星依赖互联网协议（IP）进行指挥控制以及从有效载荷传输数据。由萨里卫星技术有限公司（SSTL）建造的DMC卫星已根据《国际空间与重大灾害宪章》对卡特里娜飓风、印度洋海啸等事件的影响进行成像，用于救灾。由于DMC卫星采用了现有的商业网络标准，通过标准串行接口上的IP over Frame Relay over标准高级数据链路控制（HDLC，ISO 13239），使得将思科移动接入路由器集成到UK-DMC卫星成为可能。该方法源于SSTL早期UoSAT-12卫星上的工作。
英文摘要：
The Cisco router in Low Earth Orbit (CLEO) was launched into space as an experimental secondary payload onboard the UK Disaster Monitoring Constellation (UK-DMC) satellite in September 2003. The UK-DMC satellite is one of an increasing number of DMC satellites in orbit that rely on the Internet Protocol (IP) for command and control and for delivery of data from payloads. The DMC satellites, built by Surrey Satellite Technology Ltd (SSTL), have imaged the effects of Hurricane Katrina, the Indian Ocean Tsunami, and other events for disaster relief under the International Space and Major Disasters Charter. It was possible to integrate the Cisco mobile access router into the UK-DMC satellite as a result of the DMC satellites' adoption of existing commercial networking standards, using IP over Frame Relay over standard High-Level Data Link Control, or HDLC (ISO 13239) on standard serial interfaces. This approach came from work onboard SSTL's earlier UoSAT-12 satellite
