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 delivery networks (CDNs) have been widely used to provide reduced delay and packet loss, fault tolerance, and improved scalability for web content delivery. Additional benefits are provided for video streaming when one designs a Streaming Media CDN (SM-CDN) for either conventional single description (SD) or multiple description (MD) coding. Specifically, when precise network conditions ...

Recently, much research in quality of service (QoS) routing has focused on the unicast communication technique. However, Content Delivery Network (CDN) approach becomes popular because CDN enables effective and inexpensive improvement of Internet service quality. Therefore, we analyze in this paper a network processing two kinds of demands: content demands to CDN servers and standard unicast de...

Content Delivery Networks (CDN) aim at overcoming the inherent limitations of the Internet. The main concept at the basis of this technology is the delivery at edge points of the network, in proximity to the request areas, to improve the user’s perceived performance while limiting the costs. This paper focuses on the main research areas in the field of CDN, pointing out the motivations, and ana...

With soaring demands of Internet content services, content delivery network (CDN), one of the most effective content acceleration techniques, is applied into Internet services. Content routing functions in CDN are generally realized by load balancing system. Effectiveness of load balancing strategy determines response speed to users and user experience (UE) directly. This paper extracted the mo...

Web content delivery is based on client-server model. In this model, all the web requests for specific contents are serviced by a single web server as the requested contents reside only on one server. Therefore, with the increasing reliance on the web, the load on the web servers is increasing, thus causing scalability, reliability and performance issues for the web service providers. Various t...

Content Delivery Networks (CDNs) are commonly believed to offer their customers protection against application-level denial of service (DoS) attacks. Indeed, a typical CDN with its vast resources can absorb these attacks without noticeable effect. This paper uncovers a vulnerability which not only allows an attacker to penetrate CDN’s protection, but to actually use a content delivery network t...

An explosive growth of the use of the public internet by mobile phones along with new high speed data technologies increases the challenge of mobile data delivery. The owners of popular media typically use content delivery networks (CDN) to distribute their content. Currently there is no collaboration between the CDNs and the mobile networks. In this paper we present a novel method for caching ...

The development of Information-Centric Networking (ICN) concepts is one of the significant results of different international Future Internet research activities. In the approaches, the networking paradigm shifts from the host-to-host communication to the information-based communication. The ICN concept is receiving huge attention because of the increasing demand for highly scalable and efficie...

Popularly used to distribute a variety of multimedia content items in today’s Internet, HTTP-based web content delivery still suffers from various content delivery failures, including server failures [1], network failures [2] and routing failures [3]. Hindered by the expensive deployment cost, the conventional CDN can not deploy as many edge servers as possible to successfully deliver content i...
