Implementación de protocolo de control de congestión en simulador de eventos discretos

Abstract

Abstract: Thegrowth of telecommunication services leadsa high demand fortraffic,causingcongestionin the transmission of information that crossing through the network, generating degradation in its performance due to the high percentage of packet losses.Reactive algorithms are generally used to mitigate congestion, but at high transmission rates, their performance is affected by the capacities of the links. Therefore, according to the literature, it is better to useproactive algorithms that allocate bandwidth to each session explicitly. In thiswork, a proactive congestion control algorithm called J-PERC was implemented, which consists of a simplification of the PERC algorithm, which calculates explicit delivery rates according to the availability of network resources. The implementation was carried out in the NS-3 network simulator. Our algorithm is compared with the TCP-CUBIC algorithm for different scenarios, parameters such as: performance, packet loss, delay and jitter are analyzed. Finally, the results show that the J-PERC algorithm is more efficient than TCP-CUBIC.
