A new data link layer protocol for satellite IP networks

This paper analyze the development trend of the satellite communications, describe the existing data link layer protocol of the Satellite Networks network and conclude the characteristics and impact of the satellite network, then a new satellite network data link layer protocol (NSLP) has been proposed. 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, save resources on star and many other advantages. The new protocol has a benefit to effectively enhance the overall performance of the satellite IP networks.
