Flexible and efficient CDNs are critical to facilitate content distribution in 5G+ architectures. Current CDNs suffer from inefficient request mapping based on DNS redirection, and inefficient content distribution from origin to edge servers, through content reflection. We proposes a novel, flexible CDN architecture that removes the need for DNS-based mapping and content reflection. Instead, re...

Content Distribution Networks (CDNs) have been developed and evolved to meet the growing commercial need for efficient and secure delivery of content over the Internet. Several proprietary CDN systems are now operating successfully, fulfilling the commercial demands to a certain extent. The protocols and algorithms used in these systems are mostly of proprietary nature and not standardized. Fur...

Content Distribution Networks (CDNs) are used extensively on the WWW to relieve hot spots and reduce client latency when delivering web documents, but recently their role has been extended to the delivery of streaming multimedia content. Efficient placement of replicas in a CDN is very important, particularly when the content is large in size as is the case with high-quality TV content. This pa...

In the last decade, there has been a tendency of shifting content distribution towards peer-to-peer (P2P) technology. The reason behind this is the self-scalability of P2P systems provided by the principles of communal collaboration and resource sharing in P2P systems. By building a P2P Content Distribution Network (CDN), peers collaborate to distribute the content of under-provisioned websites...

This paper addresses the problem of mobility management in Content Delivery Networks (CDN). We introduce a CDN architecture where admission control is performed at mobility aware access routers. We formulate a Markov Modulated Poisson Decision Process for access control that captures the bursty nature of data and packetized traffic together with the heterogeneity of multimedia services. The opt...

Due to the technical developments in electronics the amount of digital content is continuously increasing. In order to make digital content respectively multimedia content available to potentially large and geographically distributed consumer populations, Content Distribution Networks (CDNs) are used. The main task of current CDNs is the efficient delivery and increased availability of content ...

This paper looks at Content-delivery networks (CDNs) originate a large fraction of Internet traffic; yet, due to how CDNs often perform traffic optimization, users aren't always assigned to the best servers for end-user performance and, in particular, suggests Provider-aided Distance Information System (PaDIS), which is a mechanism to rank client-host pairs based upon information such as RTT, b...

1. PROBLEM & MOTIVATION Smartdevices are becoming the primary or only Internet point of access for an ever larger fraction of users. Nearly a quarter of current web traffic is mobile, and recent industry studies have estimated a fourfold increase in global mobile data traffic by 2018, mainly driven by data demands and the growing number of smart phones and tablets [7]. Content delivery networks...

the date of receipt and acceptance should be inserted later Abstract The cloud CDN has been exploited as a cost-effective and elastic way for video streaming, where the content providers only pay for resources (e.g., bandwidth, storage, Web service) that they use. As a server-client solution, the cost on the content providers, especially the bandwidth cost for delivering videos from the cloud t...

While the current Internet architecture is designed based on the host-to-host communication paradigm, the real Internet usage shows that content-oriented traffic is dominant. Good examples of this paradigm shifting are Content Delivery Networks (CDNs) and Peer-to-Peer (P2P) Networks. A CDN is a system of cooperating networked computers and it provides content delivery services to end users tran...
