一种基于卫星IP网络的数据链路层协议

通过分析卫星通信网络发展趋势,阐述卫星网络中现有的数据链路层协议,梳理归纳卫星网络的特点及影响,提出了一种新型卫星网络数据链路层协议(New Satellite Link Protocol,NSLP)。分析对比表明,该协议能够有效降低链路层报头开销,提高信息传输效率。在实际应用中,新型协议具有能够简化数据链路层的功能,有与TCP/IP协议兼容性好、与IP协议耦合度高、节约星上资源等诸多优点,有利于卫星IP网络整体性能的有效提升。

A New Data Link Layer Protocol Based on The Satellite IP Networks

In this paper,we analyzed the development trend of the satellite communications,described the the existing data link layer protocol of the Satellite Networks network and concluded the characteristics and impact of the satellite network, then we proposed a new satellite network data link layer protocol (New Satellite Link Protocol, NSLP). The comparison shows that the new protocol can effectively reduce the link layer header overhead and improve the efficiency of information transmission. In practical applications, the new protocol can simplify the data link layer functions ,have a better compatibility with the TCP / IP protocol and higher IP protocol coupling degree, saves resources on star and many other advantages, the new protocol we proposed have a benefit to effectively enhance the overall performance of the satellite IP networks.
