An All-Optical Multicast Heuristic (AOMH) method is proposed to perform all-optical multicasting on WDM networks, AOMH first divides the members of a multicast group into MCG (multicast-capable group) and MIG (multicast-incapable group). If MCG is empty or the fanout constraints are not satisfied, AOMH will add some Proxy MC (PMC) nodes in MCG to satisfy the constraints. Then the multicast tree...

In this paper, we propose and evaluate the performance of a continuous media delivery technique, called threshold-based multicast. Similar to patching, threshold-based multicast allows two clients that request the same video to share a channel without having to delay the earlier request. It ensures sharing by permitting the client with the later arrival time to join an ongoing multicast session...

The Multicast Backbone (MBone), the Internet's multicast research infrastructure, has existed since the early 1990s. Since its inception, there have been few formal studies investigating the “state of multicast”, i.e. the success of multicast deployment. Our work attempts to understand (1) how the MBone is used, (2) how multicast deployment has progressed, and (3) what barriers exist for the co...

This paper addresses the problem of one-to-many, or multicast, communication in wormhole-routed, n-dimensional torus networks. The proposed methods are designed for systems that support intermediate reception, which permits multi-destination messages to be pipelined through several nodes, depositing a copy at each node. A key issue in the design of such systems is the routing function, which mu...

We study the problem of localizing repair packets when packets are lost. When repair packets are multicasted, a highly lossy receiver may swamp the entire multicast “group” with duplicate repair packets thereby wasting bandwidth; thus, the protocols need repair locality. We present a multicast layering scheme where the sender proactively distributes FEC repair packets among multiple multicast g...

In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. When more than one receiver is interested in receiving a transmission from a single or a set of senders, multicast is the most efficient and viable mechanism. In the protocol stack of the network, multicast is best implemented i...

The paper presents an efficient approach to providing fault-tolerant capability for mobile multicast. In multicast communication, packets can be concurrently sent from a source node to all members by a multicast tree. If failures occur in nodes (links) of the multicast tree, the faulty tree will be partitioned into several disconnected subtrees. For the subtrees without the source node, it cann...

An atomic multicast facility guarantees that a multicast message is delivered to the multicast group, and that every process receives messages in the same order. The availability of an atomic multicast facility greatly simpliies the implementation of many distributed system functions. Atomic multicast can be built on top of a reliable causal multicast by waiting until each processor in the grou...

Bluetooth is a low power, low cost, and short-range wireless technology developed for Personal Area Networks (PANs). A Bluetooth multicast group is a set of Bluetooth devices that desire for periodically receiving the multicast messages from the same source. For reducing the propagation delay and saving the bandwidth and energy consumptions, a multicast tree which connects all multicast members...

There are scenarios in which an IP multicast tree traverses an MPLS domain. In these scenarios, it can be desirable to convert the IP multicast tree "seamlessly" into an MPLS Multipoint Label Switched Path (MP-LSP) when it enters the MPLS domain, and then to convert it back to an IP multicast tree when it exits the MPLS domain. Previous documents specify procedures that allow certain kinds of I...
