Abstract:
We find that existing multicast protocols require either the participation of hosts in group management or partial address lists of the group members to be sent to end-points (hosts), thus creating a privacy issue. Many services suitable for multicast are transmitted via massive unicast for technical or management reasons outside the sphere of influence of the sender. The large amount of identical payload transmitted constitutes a significant waste of network resources. We address these issues by presenting MEADcast, a multicast protocol intended to support a smooth transition from massive unicast to sender-centric multicast over the Internet. Senders perform all group management while receivers do not require explicit support for the protocol. The protocol copes with varying degrees of support by routers in the network and avoids the disclosure of end-point addresses to other end-points. Performance evaluation shows a decrease of the total traffic volume in the network of up to 1:5 as compared to unicast, suggesting suitability for applications, such as Internet Protocol Television (IP-TV), video conferences, online auctions and others.
