Content Distribution Networks (CDNs) are based on a static infrastructure, and caching and replication in CDNs are performed in a static manner. We argue that it is necessary to design future CDNs in such a way that they are scalable to reach enough customers, their costs are kept low, and they provide a Quality-of-Service that satisfies the client requirements. To reach these goals, more flexi...

This document gives an overview of the current caching and replication terminology. It describes the current protocols and is a starting point for anyone interested in the subject. It starts by describing various caching and replication systems and then moves onto a brief description of most of the relevant protocols. It finishes by giving a brief product description of some of the products ava...

Caching and Replication play a critical role in alleviating network latency and server load. In this paper, we propose an Active Networks based architecture for improving caching/replication that operates by obtaining statistics from the network nodes to identify hot-spots in client access patterns. The objects are endowed with the intelligence to make their own replication decisions based on t...

Despite the extensive use of caching techniques, the Web is overloaded. While the caching techniques currently used help some, it would be better to use different caching and replication strategies for different Web pages, depending on their characteristics. We propose a framework in which such strategies can be devised independently per Web document. A Web document is constructed as a worldwid...

Multimedia services such video-on-demand service to large number of clients require stable network bandwidth provision and short network delay. In order to achieve these goals, the object replication in overlay P2P networks in a good candidate solution for both service providers and customers. However, the characteristics of peers are different from traditional content distribution infrastructu...

This memo specifies standard terminology and the taxonomy of web replication and caching infrastructure as deployed today. It introduces standard concepts, and protocols used today within this application domain. Currently deployed solutions employing these technologies are presented to establish a standard taxonomy. Known problems with caching proxies are covered in the document titled "Known ...

We proposed a search algorithm to unstructured P2P network, which consists of ranked neighbor caching, queryhit caching, and file replication to free riders. And the simulation results show that the algorithm can extend the search region but reduce the search traffic, and also balance the network load, so that acquires the whole network scalable.

Caching and replication have emerged as the two primary techniques for reducing the delay experienced by end-users when downloading web pages. Even though these techniques may benefit from each other, previous research work tends to focus on either one of them separately. In particular, caching has been studied mostly in the context of proxy server systems, while replication is the technology b...
