TCP-Peach+: enhancement of TCP-Peach for satellite IP networks

Abstract

In this letter an improvement to TCP-Peach congestion control scheme, called TCP-Peach+, is proposed to further improve the goodput performance for satellite IP networks. In TCP-Peach+, two new algorithms, jump start and quick recovery, are proposed for congestion control in satellite networks. These algorithms are based on low priority segments, called NIL segments, which are used to probe the availability of network resources as well as error recovery. Simulation experiments show that TCP-Peach+ outperforms TCP-Peach in terms of goodput and achieves fair share of network resources as well.
