Multicast seemed the only possible technique for one/many-to-many content distribution over many years. However we never had a world-wide content distribution network based on multicasting excluding some small and preconfigured networks such as mbone. Fortunately, today we have lots of content distribution networks such as gnutella, BitTorrent, eDonkey and Napster. All of these networks are bui...

The paper considers studying the perception and assessment of media content in the Russian-language social networks, analyzing the causes that affect the perception and distribution of network content. The importance of language learning and communication in Russian-language social networks, and problems of content effectiveness is determined by the growth in the number and activity of Runet us...

As wireless networks increase in popularity, the development of efficient content distribution techniques to meet the growing and constantly changing client demand becomes a necessity. Previous content distribution network proposals, targeting mainly wired networks, are not adequate to handle the high temporal and spatial variability in client demand caused by user mobility. This paper proposes...

The purpose of this research is to present topology aware overlays for efficient distributed multimedia application support. The discussed infrastructure for trans-coding multimedia streams uses self-organizing, resilient data distribution algorithms. The infrastructure takes into consideration the profile of communicating devices, network connectivity, exchanged content formats, context descri...

We present a policy-based architecture for the control and management of content distribution networks that form an overlay of caching proxies over an underlying physical network. The architecture extends the policy framework used for controlling network Quality of Service (QoS) and security to the case of content distribution networks. The fundamental advantage of a policy-based framework is t...
