An I/O intensive application is one of the most common applications in cloud computing, which is a dominant type in some occasions. However, few studies have focused on how to improve the processing efficiency of such specific type of applications. We have found out the performance bottlenecks based on the features obtained from I/O-intensive applications. By analyzing the features of files, we put...
This paper considers the characteristic of highspeed train about precise timing information, such as arrival time, depending duration on station, traveling time and current location of train, to design a video proxy agent for VoD service in train. Based on the information of current active video flows, a burst prefetching scheme is developed when the high-speed train depends on station. The video...
With rapid advances in multimedia and wireless network technologies, it is now feasible to provide live video streaming over wireless networks. However, since bandwidth is a scarce resource in wireless networks, it is important to design an adaptive bandwidth allocation scheme for video streams to make efficient use of wireless bandwidth. In this paper, we propose an adaptive bandwidth allocation...
Perceptual visual quality guarantee is of vital concern for the P2P streaming system. One of challenging issues for assuring overall video quality is to design an effective media chunk scheduler. To the best of our knowledge, there is still a lack of studies on integrating video characteristics into P2P media chunk scheduler. In this work, we attempt to integrate video characteristics, i.e. rate-distortion...
Media streaming in mobile environments is becoming more and more important with the proliferation of 3G technologies and the popularity of online media services such as news clips, live sports, and hot movies. To avoid service interruptions, proper data management strategies must be taken by all parties. We propose a two-level framework and cooperative techniques for mobile media streaming. Headlight...
