Hybrid content delivery networks (HCDN) benefit from the complementary advantages of P2P (Peer to Peer) networks and CDNs (Content Delivery Network). In order to extend a traditional CDN and enable it to offer hybrid content delivery service, we have modified a traditional domain name system-based request routing mechanism. The proposed scheme relies on an oligopolistic mechanism to balance the...

Peering points between different network providers are among the bottlenecks of the Internet. Two technical solutions to bypass them are content delivery networks (CDN) and multihoming (MH). While quality of data delivery can thus be improved, there is no research that analyses the economic effects of those technologies on the Internet. This paper argues that CDNs and MH reduce the commodity na...

A content delivery network (CDN) circumvents the congested Internet by pushing important content to large caches at the network edges. Content, produced at single points of origin, is sent to multiple points at the network edges, constituting point-to-multipoint (multicast) connections. For international wide area networks, such a scheme is most effectively implemented by using the intrinsic mu...

Broadband access network technologies such as ADSL and FTTH (Fiber To The Home) are becoming increasingly popular in Japan. In line with this trend, new broadband content delivery services using streaming technology and CDN technology are starting to appear. However, there are various issues that need to be addressed in order to provide highquality services. This position aims to encourage disc...

Problem statement: In this study, we considered an efficient and resilient large file content push problem in a large scale distributed content delivery networks and investigated the Quality of Service (QoS) requirements for content distribution. We investigated the effect of equitable dominating set in SON formation and how it was useful in reducing the redundancy? Approach: At first, we const...

The role of competition and monetary benefits in the design of Content Delivery Networks (CDNs) is largely an unexplored area. In this paper, we investigate the effect of competition among the competitive web based CDNs and show that little difference in their performance may cause significant financial gain/loss. It turns out that the economy of scale effect is very significant for the success...

Under a CDN, the client-server communication is replaced by two communication flows: one between the client and the surrogate server, and another between the surrogate server and the origin server. This distinction into two communication flows reduces congestion (particularly over popular servers) and increases content distribution and availability. To maintain (worldwide) distributed copies of...

The purpose of this thesis is to discuss issues of design, implementation and evaluation of a protocols architecture that can effectively support the interoperation and cooperation of separately administered Content Delivery Networks (CDNs). In general, a CDN can be thought of as an infrastructure that provides scalable content delivery from content providers to content consumers: specifically,...

We are in the midst of an Internet computing revolution. One vision of 21st century computing is that users will access Internet services and ‘‘resource-hungry’’ applications (e.g. gaming, streaming media, video on demand, and voice-over-IP) over lightweight portable devices rather than through some descendant of the traditional desktop PCs. In this context, distributing and processing Internet...
