As the exponential growth of traffic patterns with very different characteristics is becoming increasingly common, the high demand for a wide range of services has attracted much attention, e.g. low-priority (LP) service. To satisfy the requirements of LP service for satellite networks, a LP data transfer protocol called satellite networks (SatLTP) with the adaptation to satellite channels and taking...
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...
As a key part of next generation network (NGN) infrastructure, next generation broadband satellite networks are expected to support a variety of applications with diverse performance requirements. Research on the onboard routing protocols is the primary step to meet the various QoS related requirements, which becomes feasible with the rapid development of onboard processing capacity of satellite....

The highly topological dynamics characterize the most fundamental property of satellite networks contrary to the terrestrial networks. This manifest feature directs the researches on various aspects of satellite networks, including routing and switching architecture selection, routing protocol and reliable transmission control protocol design and enhancement, etc,. The paper quantifies the dynamical...
Low Earth orbit (LEO) satellite networks are capable of providing wireless connectivity seamlessly and continuously to any part of the world with guaranteed short round-trip propagation delay. As a key part of next generation network (NGN) infrastructure, next generation satellite networks are expected to support a variety of applications with diverse performance requirements. This paper argues that...
