Path load balancing is used for distributing workload across an array of paths to increase network reliability and optimize link utilization. However, it is not easy to realize the load balancing globally in traditional networks as the whole status of the network is difficult to obtain. To address this problem, we propose the Fuzzy Synthetic Evaluation Mechanism (FSEM), a path load balancing solution...
The Hybrid CDN-P2P architecture, or HCDN, which combines the complementary advantages of CDN and P2P networks, has been proposed to reduce the deployment cost and to improve the quality of service in file sharing and video streaming applications. A replica placement algorithm (RPA) decides where to replicate the specific data. Existing RPAs for pure CDN do not work efficiently in the HCDN architecture...
As the streaming media files growing larger and larger in size, it inevitably aggravates the network congestion and user perceive latency, to settle problem lots of caching algorithms have been applied in video-on-demand (VOD)system. However, different algorithm is correspondence to an unique caching replacement policy, which limits its applications and the effects are not very satisfied, so in VOD...
The replication and deployment of media file is one of the key issues in video-on-demand system, the replication algorithm and deployment strategy will directly affect the performance of storage balance and load balance in the system. In order to enhance the capacity of streaming media servers and handle the problem that migrating files will affect acceptance rate of user requests, in this paper we...
As a new multimedia streaming service, time-shifted TV introduces new challenges in content distribution. A number of replication algorithms were proposed to alleviate the bandwidth bottleneck, but these algorithms are not suitable for time-shifted TV due to not understanding television user access behavior. In this article, we presented a new popularity model based on analyzing of television access...
A cost-effective approach for enhancing availability of clustered system is to cache popular data across the memories of servers so as to alleviate disk I/O bandwidth bottleneck. The cache placement problem is complicated for the fact that video popularity changes over time. Moreover, as a new multimedia streaming service, time-shifted TV introduces new challenges to the problem. In this article,...
