An analysis of the end system heterogeneity in many-to-many application layer multicast

Abstract

The lack of the IP multicast deployment and the increased interest of the multi-party applications promotes the use of application layer multicast. The existing many-to-many application layer multicast schemes, Narada, TBCP, and NICE do not concern the heterogeneity of the processing capability of the end systems. We propose the modification of the existing schemes that considers the processing delay in the delivery tree construction algorithm. The performance of the modified versions are evaluated and compared with the original version using the network simulator. The analysis results and the modification proposal can be used as the basis to design a scalable and adaptable application layer multicast schemes.
