Abstract:

IP based satellite network will become an important component of Internet in the future. Due to the shared medium, it is more efficient to build transmission by using multicast than unicast. But how to run a reliable multicast in space Internet becomes a great challenge because satellite has limited resource to deal with massive feedback packages to ensure reliable transmission. Compared with ground Internet, the continuously dynamic topology of space Internet is also a big challenge to provide continuous multicast transmission. The terminals with multiple interface is more and more common, and terminals will have satellite access ability in future. How to make more efficient use of the advantages of satellite networks and terrestrial networks will become the focus of future research. In this paper, we extend current content delivery network architecture to support satellite networks at first. Then we propose a mechanism based on integrating multicast in satellite network and unicast using this architecture to take advantage of terrestrial and satellite networks. We use terrestrial network to aggregate the feedback information and retransmit loss packages to ensure reliable transmission in satellite multicast. We also propose a greedy algorithm and a zero-one linear programing model to select satellite when there are more than one satellites can connect with the terminal. We use STK to set up a simulation environment to evaluate our mechanism and algorithm. The result shows that the mechanism achieves efficient to reduce feedback information and the algorithm can balance handoff times and the numbers of selected satellite.
