中国极地考察站广域网通信建设与服务现状及展望
|
摘要
通过中国极地考察"十五"能力南极两站卫星通信网络系统项目的建设,我国南极考察站的广域网通信能力和站区网络通信能力已经有了很大提高。系统阐述南极两站的广域网通信现状,内容包括南极两站卫星通信链路的建设情况、考察站计算机网络系统建设情况以及该系统所提供的服务情况,涉及卫星通信、局域网以及VOIP等技术;对未来几年极地考察通信中可能会采用的通信技术建设提出建议。
Through the construction of a satellite communication network system during the Chinese polar expedition of the "Tenth Five-Year Plan," the capacity of the wide area network(WAN) communications at Chinese Antarctic research stations has been greatly improved. This article systematically addresses the status of the WAN communications at two Chinese Antarctic stations, describing the construction of the satellite communication links, computer network systems building, and the service provided by the system. Furthermore, it also elucidates the satellite communications, local area network, and VOIP technology that constitute part of the system. Finally, the plan for the future construction of additional communication technologies for use with polar expeditions is outlined.
