Aggregated multicast: an approach to reduce multicast state

GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002
IP 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, 2008
The 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

Multicasting in a class of multicast-capable WDM networks

Journal of Lightwave Technology, 2002
Multicast 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.

Multicast delivery based on unicast and subnet multicast

IEEE Communications Letters, 2001
In 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.

Opportunistic Multicast Scheduling with Multiple Multicast Groups

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
The 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, 2005
Application-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 ...

Aggregated Multicast for Scalable QoS Multicast Provisioning

2001
IP multicast suffers from scalability problem with the number of concurrently active multicast groups, while scalability of QoS multicast is even further from being solved. In this paper, we propose an approach to reduce multicast forwarding state and provision multicast with QoS guarantees. In our approach, multiple groups are forced to share a single

The Stability Problem of Multicast Trees in Layered Multicast

2003
In this paper, we study the stability problem of an one-to-many multicast tree in the context of cumulative layered multicast system. Especially, “How does the number of links change as the number of users in a group changes when congestion occurs?” First, we introduce a stability index to evaluate and quantify the stability of the tree.

BO-Multicast: Boolean Operation Multicast

2006 Asia-Pacific Conference on Communications, 2006
Multicast is a multiuser communication scheme. Till now, multicast has been studied to handle one multicast group at a time. However new applications such as online games need to handle multiple groups simultaneously. This paper proposes BO-Multicast; Boolean operation multicast.

Fast causal multicast

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 ...
