Analysis of TCP variants over a QoS DVB-S2 system

This paper presents a performance analysis of the TCP protocol considering the DiffServ architecture to provide Quality of Service guarantees working over a Digital Video Broadcasting - Second Generation (DVB-S2) satellite system. The analysis is carried out using the NS-2 simulator tool where three TCP variants are considered: Sack TCP, Hybla TCP and Cubic TCP. The objective is to evaluate the TCP performance taking in to account goodput, friendliness and fairness parameters and the most typical problems presented in a DVB-S2 satellite link such as delay, losses and bandwidth variations.Peer ReviewedPostprint (published version
