This paper proposes a framework for replicating content in multicastbased CDNs. We focus on the design of a scalable and robust system that provides local availability and redundancy of content. The system takes on-line and distributed replication decisions on a per-object basis. The scalability and local redundancy is achieved by partitioning the overlay of surrogate servers into fully meshed ...

Many existing peer-to-peer content distribution networks (CDNs) such as Na Kika, CoralCDN, and CoDeeN are deployed on PlanetLab, a relatively trusted environment. But scaling them beyond this trusted boundary requires protecting against content corruption by untrusted replicas. This paper presents Repeat and Compare, a system for ensuring content integrity in untrusted peer-to-peer CDNs even wh...

Abstract First-generation mobile TV has involved delivering content to cell phones. But as mobile TV evolves, it will find greater significance as part of a multifaceted video offering that combines multiple screens, devices, networks, and content types. Content, or a particular viewing session, moves with the user, across devices and across networks. Furthermore, in addition to providing an al...

In content distribution networks(CDNs), the content routing which directs user requests to an adequate server from the viewpoint of improvement of latency for obtaining contents is one of the most important technical issues. Several information, e.g. server load or network delay, can be used for content routing. Network support, e.g. active network, enables a router to select an adequate server...

The entertainment industry, facing a formidable threat from peer-topeer piracy networks, is exploring every possible means to attack these networks. The industry is also employing defensive strategies to protect media and media players from those who would extract and copy their content. These content protection systems depend on the computer industry’s newly announced ‘trusted computing’ techn...

Multimedia content distribution has appeared as a new growth market offered by network providers, defining resource access infrastructures able to support both wired and wireless accesses. Although these infrastructures have been widely studied in the last years, the main aim of those works has been focused more on the distribution process than on a suitable security infrastructure to protect t...

Content Networks (CNs) are distributed networks/systems tailored to the management, distribution, discovery and delivery of content to Internet users. They can be considered as an extension and improvement of Content Distribution Networks that emerged previously as an innovative technology that can improve the efficiency of static, time-dependent and rich media content delivery atop large-scale...
