We investigate the efficient handling of TCP/IP based applications over the GEO satellite segment of the Global Mobile Broadband System (GMBS), namely the EuroSkyWay (ESW) satellite network. We first briefly, summarise the state-of-the art of TCP protocol support over GEO satellite networks; then, we propose a novel approach, based on a “hybrid” inter-working protocol, named IWL-TCP, which operates at transport layer. IWL-TCP interfaces terrestrial IP-based networks with the satellite segment, and directly exploits the bearer services offered by the ESW satellite system. We also define a proprietary interworking Protocol Reference Model (PRM) for the ESW satellite gateways. The way of operation of IWL-TCP will be discussed and its performance analysed by means of the ns-2 simulation package.
