On the interaction of TCP with BoD in GEO broadband satellite networks

This paper reports a simulation study of the interaction between the Transmission Control Protocol (TCP) and Bandwidth on Demand (BoD) mechanisms in broadband satellite networks. It forms part of a broader effort aiming at the identification of the proper mechanisms and algorithms to efficiently carry TCP traffic over these networks. We investigate two aspects of this rather complicated interaction, related to the possible BoD configurations and the TCP tuning. parameters, focusing on GEO satellite networks. The impact on TCP performance and system efficiency is evaluated and effects that cannot be easily captured by analysis are highlighted.
