In order to achieve high performance IP address lookup and a specified circuit suitable for onboard IP switch, through the analysis and comparison of the existing onboard routing search algorithms, this paper put forward a novel IP address routing lookup algorithm, which called two-layer compressed trie search algorithm. This algorithm could not only implement “one-to-one” unicast satellite routing...
According to previous studies, the UDLs (user data links) or ISLs (intersatellite links) switch and failure can result in the packet reordering in low Earth orbit (LEO) satellite networks. The packet reordering can severely deteriorate the performance of transmission in LEO satellite networks, especially at very high levels of packet reordering. In order to improve the TCP (transmission control protocol)...
In this paper we study the influences of packet reordering on the throughput and link utilization in Low Earth Orbit (LEO) satellite networks. In the absence of any packet reordering, the throughput and link utilization remain high. Our results indicate that packet reordering combined with packet error can severely deteriorate the performance of transmission in LEO satellite networks, especially at...
