Análise de Desempenho de Protocolos Multicaminho para Vı́deo Streaming em Tempo Real

The mobile devices technological evolution and the increased availability of IP (Internet Protocol) networks, created new opportunities for multimedia content distribution over Internet. Real-time applications require high quality service and are not tolerant to mean packet delay above 200ms, delay variations and throughtput reduction. The use the multipath protocols in real-time video streaming presents several advan- tages, leading to a better quality and network resilience. This paper presents a study on performance of high definition video streaming, using multipath transport protocols, comparing the Stream Control Transfer Protocol (SCTP), Concurrent Multipaht Transfer (CMT), and a path selection technique based on the lower path delay called delay centric.
