Content Delivery Networks (CDNs) provide an efficient support for serving http and streaming media content while minimizing the network impact of content delivery as well as overcoming the server overload problem. For serving the large documents, software download packages and media files, there is an additional problem of the original content distribution across the edge servers in CDN infrast...

Over the past decade, content delivery networks (CDNs) have attracted substantial Internet traffic and improved quality of experience for Internet users. However, the evolution of the Internet ecosystem, which is driven by underlying economic incentives and ever emerging technologies, posts great challenges to the existing commercial CDNs (CCDNs). Thoroughly understanding the CDN industry from ...

With the explosive growth of the Internet, many new online services and applications are emerging. Some popular applications impose new challenges to the traditional Internet architecture and protocols. To alleviate the scalability burden in delivering popular Internet services to a large number of users, Web caching and content distribution technologies have been proposed, developed and deploy...

Cache consistency at web intermediaries is required for scalable web content delivery. In this paper we describe the Web Content Distribution protocol (WCDP), which is an invalidation and update protocol to provide cache consistency for a large number of frequently changing web objects. WCDP supports different levels of consistency: strong, delta, weak, and explicit. It supports atomic invalida...

One major factor that heavily affects the performance of a content distribution network (CDN) is placement of the surrogates. Previous works take a network-centric approach and consider only the network traffic. In this paper, we propose solutions to optimal surrogate placement, taking into consideration both network latency and capacity constraints on the surrogates. For CDNs with a tree topol...

Application level active networks provide a way of transforming the current network infrastructure into one where new services and protocols are more easily adopted without the need for standardization. In this paper we deal with an application layer active networking system, and address the problem of publishing and distributing software components, provided by trusted service providers, throu...

Abstract overlay networks have been considered enablers of efficient management for decentralized, large scale service deployments. A Content Delivery Network (CDN) is an example of service falling within this category. The result of our research is WebDMF, a management framework for distributed services based on the Web-Based Enterprise Management (WBEM) family of specifications. Abstract desi...

A Content Distribution Network (CDN) is an overlay network where servers replicate contents and distribute client’s requests with the aim at reducing delay, server load and network congestion, hence improving the quality of service (QoS) perceived by end clients. Because of server constraints and costs involved in the replication process, it is not reasonable to replicate the contents over the ...


 The owner of the centralized video platform has more control over uploaded content than producer does. But other Blockchain-based decentralized services are attempting to reduce ad pressure and get rid middlemen. article suggests a combination safe encryption technique an access mechanism created "with technology" create successful streaming built on Blockchain. Peer-to-peer (P2P) overla...

The current packet based stream authentication schemes provide effective and efficient authentication over a group of packets transmitted on erasure channels. However, by fixing the packets in transmission, any packet manipulation will cause authentication failure. In p2p content delivery network where a proxy-in-the-middle is able to store, forward, transcode and transform the stream, previous...
