Peer-to-Peer (P2P) technology has been widely adopted by various live streaming systems recently, due to its better scalability and lower costs compared with the client-server architecture. However, P2P live streaming systems are still challenged by the flash crowd scenarios, which often occur when a great number of users suddenly arrive and compete for the limited upload bandwidth of a P2P system...
Content distribution networks (CDNs) improve the performance of content delivery by replicating the popular content on surrogate servers deployed at the edge of the Internet. The CDN-P2P architecture, which combines the complementary advantages of both CDN and P2P networks, can improve the quality of service (QoS). In this paper, we propose a k-coordinated decentralized replica placement algorithm...
The Hybrid CDN-P2P architecture, or HCDN, which combines the complementary advantages of CDN and P2P networks, has been proposed to reduce the deployment cost and to improve the quality of service in file sharing and video streaming applications. A replica placement algorithm (RPA) decides where to replicate the specific data. Existing RPAs for pure CDN do not work efficiently in the HCDN architecture...
Hybrid content distribution network (HCDN), integrating complementary advantages of CDN and P2P, is used to improve efficiency of large-scale content distribution. In this paper, to achieve in-depth understanding of HCDN??s effectiveness, we carry out a detailed performance evaluation based on deterministic fluid model. We also provide numeric results of HCDN, comparing with conventional CDN and P2P...
It is meritorious but hard to develop a scalable and manageable system to effectively distribute the large-scale multimedia contents. In this paper, an integrated hierarchical content distribution system is proposed, which utilizes the complementary advantages of both CDN (content delivery network) and P2P (peer-to-peer). The hybrid architecture and distribution operations are presented in detail...
