Planet Internet is not a dream, international space station-NASA Interplanetary Internet DTN service logging, the Internet-IT news

IT information on Earth using the Internet have become commonplace, Internet has become an integral part of many people's lives. But it also shows that the Internet is not new Earth, taking into account the future development of mankind, Star Internet has been mentioned NASA agenda.

NASA international space station currently testing can tolerate delay networks (DTN) services, the service uses a store-and-forward mechanism for sending packets, the packet can be forwarded to node uses to store part of the communication path before, and then reassembled at the destination. This destination can be ground stations, the deep space craft or of human life on other planets. After development is complete, Internet access is no longer a dream of Mars.

DTN works and traditional Internet protocols, in agreement with the traditional data transmission for all nodes at the same time needs to be available. Currently NASA is working with the TCP/IP protocol developer Vinton g. Cerf research DTN service in close collaboration, but it was unclear when put into use. Not only limited to the interplanetary Internet, Vinton g. Cerf that the technology can also be used for IoT IOT can solve device stop communications problems due to insufficient power.

火星上网不是梦，国际空间站开测星际互联网DTN服务 - NASA,互联网 - IT资讯

IT资讯讯 在地球上使用互联网已经司空见惯，Internet已经成为很多人生命中不可或缺的部分。但这也表明地球上网已经不是新鲜事，考虑到人类今后的发展，星际互联网已经被NASA提到日程上来。

目前NASA正在国际空间站测试可容忍延迟网络（DTN）服务，该服务采用储存转发机制发送数据包，数据包在能被转发前要在通信路径的节点上储存一部分，然后在最终目的地重新组装。这个目的地可以是地面站、深空飞行器或人类生活的其他星球。研发完成后，火星上网不再是梦想。

DTN的工作机制与传统互联网协议不同，在传统协议下，数据传输需要所有节点同时可用。目前NASA正与TCP/IP协议开发者Vinton G. Cerf密切合作研发DTN服务，但还不清楚何时能够投入使用。其实不仅限于星际互联网，Vinton G. Cerf认为该技术还可用于IoT物联网，可解决设备因电力不足而停止通信的问题。
