Abstract

Although the IP multicast can be solution for various new emerging services which require active participation from many users, it does not work well in the current Internet which is based on the unicast communications [5]. Various alternative methods are being developed to overcome this limitation of the current Internet. One such method is an overlay multicast method. Most overlay multicast uses bi-directional TCP connection between the end-systems. Although TCP guarantees the ordered sequence and reliable transmission, TCP does not satisfy all properties of the overlay multicast in viewpoint of reliable transmission which includes establishment of new connection from new end-system. This paper introduces reliable data delivery scheme for relay-based overlay multicast. The proposed method is based on the architecture for n-plex multicast service which realizes simultaneous communication between multiple senders and multiple receivers [1][2].
