Applying performance evaluation to large-scale contents delivery system

Abstract

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 shows the performance estimation scheme for RMTP; a reliable multicast protocol for bulk-data transfer and applies it to the scheduling function in megacast; a contents delivery system for large numbers of receiver. Some performance characteristics of RMTP are also examined.
