Summary

Descripción general del contenido del recurso.

El objetivo de este artículo es contribuir en los aspectos relacionados con la degradación de performance en los protocolos de transporte confiables, ante el fenómeno de congestión de las redes globales, en particular tomando como modelo de referencia SCTP (Stream Control Transmission Protocol). Al problema de la congestión se suman el reordenamiento de paquetes y el cambio brusco del round-trip-time, muy común en redes wireless. Estos comportamientos de la red subyacente producen una seria degradación de la performance de los protocolos de transporte . Se propone para SCTP un mecanismo adaptativo con el fin de disminuir la ocurrencia de los denominados falsos timeouts y falsos fast retransmits, que producen degradación en performance y la subutilización de recursos, principalmente de ancho de banda y buffers. La extensión del protocolo SCTP que incluimos la denominamos “RR-SCTP”. The objective of this paper is to contribute to the analysis of degradation of performance in realible transport protocols in the presence of global networks congestion assuming, as the reference model, the case of the SCTP (Stream Control Transmission Protocol). Beyond the question of congestion, this study addresses packages reordering and round-trip-time abrupt changes that are very common in wireless networks. With the current congestion control mechanisms, these underlying network behaviors significantly degrade the performance of the transport protocols. We propose an adaptive algorithm for the SCTP that will diminish the frequency of the “false timeouts” and the “false fast retransmits”. These issues both degrade performance and impede the maximum utilization of resources (principally, the bandwidth and the buffers).We call our SCTP protocol extension "RR-SCTP".
