Evaluation of Reliable Multicast Applications for Large-Scale Contents Delivery

Reliable Multicast has been applied to large-scale contents delivery systems for distributing digital contents to a large number of users without data loss. Performance evaluation of reliable multicast is useful for delivery time estimation in active delivery systems as well as for designing communication protocols and systems. This paper evaluates the implementation and performance of RMTP; a reliable multicast protocol for bulk-data transfer for several types of contents delivery services. System configuration is examined including operation function such as delivery scheduling based on performance evaluation. Furthermore, research issues are discussed when reliable multicast is applied to emerging broadband network services.
