A content distribution network (CDN) is a system to improve the delivery of content to the end users on the Internet, in which popular content may be cached or replicated at a number of servers, placed closer to some client populations. The design of a CDN consists of defining which content should be replicated at each server, the number of servers, where they should be placed in the network, w...

Internet evolves and operates largely without a central coordination, the lack of which was and is critically important to the rapid growth and evolution of Internet. However, the lack of management in turn makes it very difficult to guarantee proper performance and to deal systematically with performance problems. Meanwhile, the available network bandwidth and server capacity continue to be ov...

Content Delivery Networks (CDNs) are a vital component of the Internet’s content delivery value chain, servicing nearly a third of the Internet’s most popular content sites. However, in spite of their strategic importance little is known about the optimal pricing policies or adoption drivers of CDNs. We address these questions using analytic models of the market structure for Internet content d...

Content delivery networks play a crucial role in today’s Internet. They serve a large portion of the multimedia on the Internet and solve problems of scalability and indirectly network congestion (at a price). However, most content delivery networks rely on a statically deployed configuration of nodes and network topology that makes it hard to grow and scale dynamically. We present ActiveCDN, a...

The Internet is fast becoming the de facto content delivery network of the world, supplanting TV and physical media as the primary method of distributing larger files to ever-increasing numbers of users at the fastest possible speeds. Recent trends have, however, posed challenges to various players in the Internet content delivery ecosystem. These trends include exponentially increasing traffic...

In this paper, the authors discuss their experiences implementing, operating, and optimizing a content delivery network for Canada’s largest news website, that of the Canadian Broadcasting Corporation (CBC). The site receives over one million unique visitors per day. Although CBC uses the Akamai Aqua Platform (formerly EdgeSuite) as its content delivery network of choice, the lessons described ...

Traditional system based on the current form of distance education network technology does not support the existence of dynamic multimedia data and realtime streaming data, as well as the existence of streaming media technology in the server bottleneck problem. The key technologies of streaming media digital resources transmission based on CDN (Content Delivery Network) and P2P (peer-to-peer) i...

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...

As more aspects of our work and life move online and the Internet expands beyond a communication medium to become a platform for business and society, Content Delivery Networks (CDNs) have recently gained momentum in the Internet computing landscape. Today, a large portion of Internet traffic is originating from CDNs. The ultimate success of CDNs requires novel policies that would address the i...

The current deployment approach of the commercial Content Delivery Network (CDN) providers involves placing their Web server clusters in numerous geographical locations worldwide. However, the requirements for providing high quality service through global coverage might be an obstacle for new CDN providers, as well as affecting the commercial viability of existing ones. It is evident from the m...
