The video content for on-demand services is generally stored and streamed in a compressed format. The compressed video is naturally with the VBR (variable-bit-rate) property and the stream traffic is highly burst. Subject to the QoS-guaranteed playback, the WAN bandwidth needs to allocate the video's peak bit rate if there is no client buffer for regulating the video delivery [7][8][9][10][11]....

High quality video content for on-demand services is usually stored and streamed in a compressed format with a VBR (variable bit rate) property; however, the streaming traffic is extremely bursty. If there is no client buffer to regulate the video’s delivery, the backbone WAN (wide area network) bandwidth needs to allocate the video’s peak bit rate to guarantee playback quality. To reduce the b...

Recent years have seen a tremendous growth in streaming continuous media such as videos over the Internet, resulting in an enormous increase in the demand on various server and networking resources. To minimize service delays and reduce the loads placed on these resources, we propose a Video Caching Network (VCN) that utilizes an aggregated cache space of distributed systems along the delivery ...

With the continuous development of 5G network technology, amount data has surged. Network transmission technology needs improvement. To ensure reliable data, reduce congestion and energy consumption, paper proposed an effective edge cache collaboration routing strategy opportunistic social networks in trust community, namely community algorithm (ECTC). The proposes that nodes are used to carry ...

In this paper, we propose, design, implement, and evaluate a proxy caching system for MPEG4 video streaming services for heterogeneous users. In our system, a video stream is divided into blocks for efficient use of the cache buffer and the bandwidth. A proxy retrieves a block from a server, deposits it in its local cache buffer, and provides a requesting client with the block in time. It maint...

In this work we describe the Collapsed Cooperative Video Cache (CCVC), a novel scalable technique for delivering video streams over content distribution networks (CDNs). C-CVC is based on the idea of collapsing client buffers into the proxy caches on the CDN edges nearest to the clients while enforcing transparently cooperation among clients that share the same video content. As a result of sto...

Preventing users from accessing adult videos and at the same time allowing them to access good educational videos and other materials through campus wide network is a big challenge for organizations. Major existing web filtering systems are textual content or link analysis based. As a result, potential users cannot access qualitative and informative video content which is available online. Adul...

In light of advances in processor and networking technology, especially the emergenceof network attached disks, the traditional clientserver architecture of file systems has become suboptimal for many computation/data intensive applications. In this paper, we introduce a revised architecture for file management employing network attached storage: the dynamic file server environment (Dynamo). Dy...

This paper presents a hardware based cache scheme to detect selfish nodes in mobile ad hoc network. In this scheme, the hardware monitors the activities of the upperlayer software and reports the misbehavior about the software to other mobile nodes in the network. The hardware cache stores the identity information of recently received packets. The detection mechanism uses the cache to tell the ...
