Recently, user who uses a multimedia files demands a high capacity file via internet. However, it is difficult to guarantee QoS about providing high capacity files by internet because that has an inconstant bandwidth. For guaranteeing the QoS, CDN (Content Delivery Network) is generally used as a method of contents delivery service. Based on CDN, we propose Content Distribution and Management u...

Content Distribution Network (CDN) technology has been proposed to deliver content from content nodes placed at strategic locations on the Internet. However, only companies or organizations, who can pay for the services of CDNs, have the privilege of using CDNs to distribute their content. Individual users (peers) have to resort to more economical peer-to-peer (P2P) technologies to distribute t...

This paper is to design an integrated consistency-control algorithm for mobile contents delivery network (M-CDN) to enhance the efficient utilization of network resource and support the client mobility. Firstly, by carrying out an analysis of mobile surrogates’ characteristics, for a given content which has been changed on its original node, only a limited number of its replicas instead of all ...

Most CDNs pay more attention to CSP (Content Service Provider) to gain more profit from faster access rate and lower server load. However they ignore that the CDNs pay the ISPs (Internet Service Provider) for using the underlying networks based on the traffic volume generated by CDN servers. ISPs expect to save their operational cost from inter-ISP traffic and improve the QoS (Quality of Servic...

Recently there has been an increasing deployment of content distribution networks (CDNs) that offer hosting services to Web content providers. CDNs deploy a set of servers distributed throughout the Internet and replicate provider content across these servers for better performance and availability than centralized provider servers. Existing work on CDNs has primarily focused on techniques for ...

Content Delivery Networks (CDNs) are commonly used for improving the End User experience of a content delivery service while keeping cost at a reasonable level. This document focuses on use cases that correspond to identified industry needs and that are expected to be realized once open interfaces and protocols supporting the interconnection of CDNs are specified and implemented. This document ...

Since the early days of the world wide web (WWW), the information infrastructure provided over the Internet has improved considerably. The simplicity of offering and accessing data on the WWW and the increase of commercial uses of the Internet are major reasons for this development. During this development, it was discovered that shifts in popularity of content and services offered over the web...

The success of the Content Delivery Networks (CDN) in the recent years has demonstrated the increased benefits of the deployment of some form of “intelligence” within the network. Cloud computing, on the other hand, has shown the benefits of economies of scale and the use of a generic infrastructure to support a variety of services. Following that trend, we propose to move away from the smart t...

Hosting a Web site at a single server creates performance and reliability issues when request load increases, availability is at stake, and, in general, when quality-of-service demands rise. A common approach to these problems is making use of a content delivery network (CDN) that supports distribution and replication of (parts of) a Web site. The nodes of such networks are dispersed across the...
