TCP Wave

TCP Wave is a new transport protocol designed by the Satellite Multimedia Group at University of Rome "Tor Vergata". TCP Wave is an alternative to the standard TCP versions for current broadband networks where a set of challenging communication aspects can impair performance: i.e. large latency links, handovers, and dynamic network switching. A full protocol algorithm and specification is presented in. The performance has been assessed under different network and application configurations in. TCP Wave envisages sender-side only modifications, guaranteeing fairness when sharing the bottleneck with standard TCP flows. From the design point of view, TCP Wave is based on burst transmission paradigm. Sender sends packets in bursts at time intervals scheduled by an internal timer (TxTime). This approach allows the TCP receiver triggering in trains, which carry information about the network congestion (from RTT measurements) and the link capacity (by measuring the ACK train dispersion). The TCP Wave sender relies on the ACK-based measurements to update its internal timer for packet intervals to achieve the optimal transmission rate. This approach allows TCP Wave to overcome the ACK-clocked window-based transmission followed by other TCP variants. Decoupling of the packet transmission from the experienced RTT, allows TCP Wave sender to have a proactive rate control with a fast tracking into the available end-to-end capacity. See Also
