By the significant development of network routine which entail of Internet and the transmission of high - end terminals such as smart - phones , laptops , Ipod or any media receiver, media broadcasting streaming service is fetching one of the major communication technologies. However current packet networks still cannot provide a stable transmission quali ty and it can cause stream quality deprivation . Especially, the main factor affecting quality is congestion across a network. Well - organized utilization of available bandwidth over multiple access networks of multi - homed devices can be a reasonable solutio n to provide good quality for real - time media streaming applications. In this paper, we propose Real Time & Multi - path Transmission Protocol (RTMTP), a transport layer protocol in which multiple path real - time transport is available. Our protocol exploits RTP’s real - time features and SCTP’s multi - homing capability by enabling the use of multiple paths to transfer media streams. RTMTP uses the end - to - end sender - based bandwidth estimation mechanism to measure the actual available bandwidth of each path. To ex ploit network bandwidth productivity of multiple paths, the RTMTP shares traffic among those paths and the transmission rate for each path is determined allowing to the measured available bandwidth. RTMTP also helps users to use their preferred access netw ork as much as possible. Our simulation results show that RTMTP improves streaming broadcast output .
