A Scalable Framework for Content Replication in Multicast-Based Content Distribution Networks [chapter]

Yannis Matalas, Nikolaos D. Dragios, George T. Karetsos
2006 Lecture Notes in Computer Science  
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 proposed framework can incorporate any set of local metrics and constraints for deciding the placement of replicas, thus allowing the CDN designer to tune it to his specific deployment characteristics  ...  purely local algorithms, which are simple and scalable but the number of replicas taken may be far from the optimal while they make no provisions at all for their relative placement.  ...

An economic replica placement mechanism for streaming content distribution in Hybrid CDN-P2P networks

Mehran Garmehi, Morteza Analoui, Mukaddim Pathan, Rajkumar Buyya
2014 Computer Communications  
Hybrid CDN-P2P networks blend Content Delivery Networks (CDN) and Peer-to-Peer (P2P) networks to overcome their shortcomings. Replica placement in these networks is still an open problem.  ...  The proposed solution relies on economic model of the Hybrid CDN and employs a dynamic mechanism to optimize the number and places of replicas for P2P service.  ...  Based on this assumption, a dynamic replica placement mechanism is designed to replicate the streaming content in P2P mode.  ...

Replication algorithms to retrieve scalable streaming media over Content Delivery Networks

Zhou Su, Jiro Katto, Yasuhiko Yasuda
2003 Proceedings of the 5th ACM SIGMM international workshop on Multimedia information retrieval - MIR '03  
CDN (Content Delivery Networks) improves end-user performance by replicating web contents on a group of geographically distributed content servers.  ...  However, current replica strategies in CDN are to simply and repeatedly keep the complete replica of the original object on many content servers.  ...  Therefore, the appropriate placement of server replicas benefits content providers by reducing latency for their clients, and benefits ISPs by reducing bandwidth consumption and transmission cost.  ...
