On the efficiency of multicast
IEEE/ACM Transactions on Networking, 2001The average number of joint hops in a shortest-path multicast tree from a root to m arbitrary chosen group member nodes is studied. A general theory for all graphs, hence including the graph representation of the Internet, is presented which quantifies the multicast reduction in network links compared to m times unicast. For two special types of graphs,

A secure multicast protocol for the internet's multicast backbone
International Journal of Network Management, 2001AbstractIn this paper we propose a secure and efficient multicast protocol where the key management is distributed to local groups. The proposed protocol takes advantage of MBone topology to maintain scalability and efficiency at the same time. Copyright © 2001 John Wiley & Sons, Ltd.

Multicast delivery based on unicast and subnet multicast
IEEE Communications Letters, 2001In spite of the numerous works previously made, IP multicasting has not been widely deployed in the public Internet. We present a realistic alternative scheme for IP multicasting, which is based on the unicast transport from a remote sender to a local subnet and the multicast forwarding to receivers within the subnet.

Multicasting in a class of multicast-capable WDM networks
Journal of Lightwave Technology, 2002Multicast is the ability to transmit information from a single source node to multiple destination nodes. Multicast can be supported more efficiently in an optical domain by utilizing the inherent light splitting capacity of optical switches than by copying data in an electronic domain.

A multicast congestion control mechanism for reliable multicast
Proceedings Third IEEE Symposium on Computers and Communications. ISCC'98. (Cat. No.98EX166), 2002This paper evaluates a congestion control mechanism for reliable multicast applications that uses a small dynamic set of group members, or representatives, to provide timely and accurate feedback on behalf of congested subtrees of a multicast distribution tree. Through simulations, we evaluate our algorithm with and without TCP cross traffic.

Aggregated multicast: an approach to reduce multicast state
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002IP multicast suffers from a scalability problem with the number of concurrently active multicast groups because it requires a router to keep the forwarding state for every multicast tree passing through it and the number of forwarding entries grows with the number of groups. In this paper, we propose an approach to reduce the multicast forwarding state.

Multicast Cryptosystem: A Cryptosystem for Secure Multicast Communication
2008 IFIP International Conference on Network and Parallel Computing, 2008The recent growth of multimedia group of applications is driving the need for secure multicast communication. Secure multicast communication in dynamic environments like wireless networks and grids are potentially of critical concern. As multicast group members move in and out of the group, in order to preserve confidentiality, it becomes imperative to

Opportunistic Multicast Scheduling with Multiple Multicast Groups
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011The use of opportunistic multicast scheduling (OMS) for systems with multiple multicast groups is examined in this work. Here, a general downlink scenario where a single basestation is to transmit independent data streams to multiple groups of users is considered.

Construction of a Robust Multicast Tree for Application-Level Multicast
IEICE Transactions on Communications, 2005Application-level multicast (ALM) is a feasible alternative to IP multicast. In ALM, multicast related features, such as group membership management, multicast routing and packet replication, are implemented at end-hosts instead of routers. A multicast distribution tree is constructed in the application layer, so all nodes in this tree are end-hosts ...

ACM SIGOPS Operating Systems Review, 1990
We begin by outlining a new protocol that efficiently implements a reliable, causally ordered multicast primitive and is easily extended into a totally ordered one. Since measurements show that the dominant cost of this protocol is message transport, the design of a lower level multicast transport protocol is ...
