The Datagram Congestion Control Protocol (DCCP) [1] is being proposed by IETF as a transport protocol to support multimedia traffic. Two congestion controls mechanisms have been proposed so far for DCCP, namely TCP-Like [2] and TCP-Friendly Rate Control (TFRC) [3]. In this paper, we experimentally investigate the DCCP performance with its two congestion(More)
Next-generation broadband satellite systems will have the capability to provide costeffective universal broadband access for the users. In order to meet users’ requirements on high quality multimedia services, many enhancements have to be made on the existing satellite technologies. One of the promising methods is the introduction of cross-layer design.(More)
This paper introduces a cross-layer approach for improving QoS guaranties to interactive multimedia applications over an efficient satellite access assignment scheme (ondemand). It particularly focuses on the communication opening which represents the weakness of on-demand capacity allocation in the satellite context (due to significant delays). It finally(More)
