Abstract

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.
