Recently, efficient network resource management and quality-of-service (QoS) guarantee become more and more important for multimedia applications and services, especially when considering network delays. In this paper, an optimal bandwidth allocation scheme that achieves maximal utilization of the client buffer and minimal allocation of bandwidth for each(More)
In this paper, an end-to-end real-time adaptive protocol for multimedia transmission is presented. The transmission rate is determined by the quadratic probing algorithm that can obtain the maximal utilization of the client buffer and minimal allocation of the network bandwidth. It is also coupled with a congestion control mechanism that can effectively(More)
Efficient utilization of network resources is essential in the provision of quality multimedia services. Different approaches have been proposed to shape the multimedia streams as a transmission schedule with smoothed traffic burst. In this paper, we concentrate on the problem of efficient use of bandwidth and client buffer. For this purpose, an optimal(More)
High bandwidth requirements in multimedia transmission make the efficient use of limited network resource a challenging task, especially when multiple clients make their requests to the server simultaneously. In this paper, we propose a self-adjusted network transmission mechanism for multiple clients. Instead of assigning a fixed bandwidth for each client,(More)
In this paper, an end-to-end congestion controlled optimal bandwidth allocation scheme with a transmission rate control mechanism for multimedia transmission is proposed. This rate control mechanism aims at minimizing the allocated rate and maximizing the utilization of the client buffer. By adjusting the transmission rate in response to the buffer(More)
In this paper, a secure and adaptive multimedia transmission framework is proposed to maintain the quality of service (QoS) of the multimedia streams during the Denial-of-Service (DoS) attacks. A DoS attack generates a large amount of traffic, which will occupy the bandwidth and degrade the quality of video. The proposed framework consists of two(More)
In this paper, we propose a multi-buffer scheduling scheme for streaming video systems. A transmission rate is obtained via a rate control algorithm, which optimally utilizes the network bandwidth and client buffer resources. The server side maintains multiple buffers for packets of different importance levels. It schedules the transmission of each packet(More)
