Abstract(in English) | TCP is the most widely used transport protocol on today's Internet. A large part of its success is due to its ability to probe for unused bandwidth while also backing off its transmission rate upon detection of network congestion. Despite the fact that several mechanisms have been presented in recent literature to improve TCP, there remain some vexing attributes that impair TCP's performance. In this paper, we address the issue of the efficiency and fairness of TCP in multi-hops satellite constellations. We mainly focus on the effect of the change in flow count on TCP behavior. In case of handover occurrence, a TCP sender may be forced to share a new set of satellites with other users resulting in a change of flow count. Our work argues that the TCP rate of each flow should be dynamically adjusted to the available bandwidth when the number of flows, competing for a single link, changes over time. We show through simulations that our fair share scheme improves fairness by guaranteeing a fair progression in window size for each flow, decreases the number of losses, and makes better utilization of the bottleneck link. |
