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 advantage of extra bandwidth without interfering high priority flows is proposed. In order to use extra bandwidth adaptable, SatLTP achieves precise adjustment of the congestion window by dynamically updating indicative parameters and selecting optimal window control policies. Simulation results over satellite networks show that SatLTP enhances the throughput of satellite channels in terms of being friendly and non‐intrusive toward other protocols (e.g. TCP) and able to effectively exploit the available resources over satellite networks.
