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...

With the growth of multimedia applications and reshaping of high-speed internet, large size multimedia content can be delivered smoothly to end users for their entertainment. These end users not only consume multimedia content such as online TV program, and but also produce the multimedia content such as photos and video clips to the internet servers. The social relationships among end users si...

A Content Distribution Network, or CDN, is a system to improve the delivery of content to the end users (or clients) in the Internet, in which popular content may be cached or replicated at a number of servers, placed closer to some of the client populations. The design of a CDN consists of defining: (a) which content should be replicated at each server (server content), (b) the number of serve...

Content Distribution Networks (CDNs) are a class of successful content delivery architectures used by the most popular Web sites to enhance their performance. The basic idea is to address Internet bottleneck issues by replicating and caching the content of the customer Web sites and to serve it from the edge of the network. In this paper we evaluate to what extent the use of a CDN can improve t...

Sharing content such as scientific papers or multimedia data in locally distributed organisations or between a group of co-operating users still poses a couple of problems. Existing systems like centralized client-server solutions and distributed peer-to-peer applications both suffer from their characteristic disadvantages. Centralized systems on the one hand have advantages in their good manag...

One strategy for alleviating excess latency (delay) in the Internet is the caching of web content at multiple locations. This reduces the number of hops necessary to reach the desired content. This strategy is used for web content such as html pages, images, streaming video, and Internet radio. The network of servers which store this content, and the collections of objects stored on each server...

Content distribution networks (CDNs) which serve to deliver web objects (e.g., documents, applications, music and video, etc.) have seen tremendous growth since its emergence. To minimize the retrieving delay experienced by a user with a request for a web object, caching strategies are often applied contents are replicated at edges of the network which is closer to the user such that the networ...

We address the question: What is the best way to construct a mesh overlay topology for multimedia content distribution, such that the highest streaming rate can be achieved? We model overlay capacity correlations as linear capacity constraints (LCC) and propose a distributed algorithm that constructs an overlay mesh which incorporates heuristically inferred linear capacity constraints. Our simu...
