Performance evaluation of mixed SCTP and TCP traffic over last hop wifi

The use of the internet has increased significantly with the continued increase in wireless communication devices. Recently, there is a large number of research contribution focused on Stream Control Transmission Protocol (SCTP). Multi-homing is an important feature of SCTP which improves the communication performance by usage of multiple paths during association establishment, and it can bring significant improvements of throughput. In this thesis we evaluate the performance of SCTP and TCP traffic in the WLANs and we investigate the SCTP multi-homing to improve the communication performance in WLANs. We conducted some experiments to evaluate the performance of SCTP multi-homed host under various channel bit rates and mobility speeds. The results indicate that when the intensity of background traffic increases the SCTP multi-homed host with higher channel bit rate has better performance. In addition, the SCTP multi-homed host with using lower mobility speed has higher performance (throughput, delay and packet loss).

Mecanismos de nivel de transporte para la optimización de envíos sobre Long Fat Networks

Este artículo investiga los mecanismos de diferentes protocolos de transporte en transferencias sobre redes de alta capacidad y alto retardo, conocidas como Long Fat Networks (LFNs) para un envío eficiente de los datos. Transport Control Protocol (TCP) presenta limitaciones de rendimiento y flexibilidad. En la literatura se pueden encontrar diferentes propuestas de variantes del comportamiento de TCP, protocolos como Stream Control Transmission Protocol (STCP) o soluciones que proporcionan una comunicación confiable y mecanismos de control de congestión sobre User Datagram Protocol (UDP). En este artículo se presentan una serie de mecanismos de nivel de transporte para la optimización de transferencias de datos sobre redes LFN. Estos mecanismos ofrecen un rendimiento elevado utilizando todo el ancho de banda disponible del enlace mediante un proceso de cálculo del estado de la red y un control de congestión activo para la utilización de todo el bandwidth, a la vez que reactivo en caso de producirse pérdidas para evitar congestiones en la red. El objetivo es demostrar la eficiencia de dichos mecanismos, así como su adaptabilidad y aggressive friendliness respecto a otros protocolos de transporte mediante el despliegue de una serie de pruebas expuestas en este artículo.

Analisa Performansi Protokol TCP, UDP dan SCTP Pada Lalu Lintas Multimedia

This study aims to analyze Performance of TCP, UDP and SCTP Protocol on Multimedia Traffic. The TCP (Transmission Control Protocol) protocol, UDP (User Datagram Protocol) and SCTP (Stream Control Transmission Protocol) reside on the same layer in the OSI-Layer at the Transport layer that controls the flow of data, data packets and so on. This research uses windows operating system and Softperfect Network Protocol Analyzer software. Where network analysis software has a complete feature such as can filter almost all the protocol on the OSI-Layer, has a report of easy to read results and so forth. From the test results conducted for three days by analyzing the online and offline way obtained SCTP protocol results both for Multimedia activities but can not be used simultaneously with other activities (such as video conversations). for everyday activities should use TCP and UDP protocol because it tends to be stable.Keyword : TCP, UDP, SCTP
