IP multicast is advantageous for high quality streaming applications and future needs in the Internet. However, it is generally recognized that IP multicast requires significant routing coordination and configuration, and hence its routing protocols are non-scalable. Recently, Source-Specific Multicast (SSM) has been standardized and proposed as the deployable IP multicast communication archite...

The use of an efficient multicast tree can substantially speed up many communication-intensive MPI applications. This is even more crucial for Grid environment since MPI runtime has to work on wide area network with very different and unbalanced network bandwidth. This paper proposes a new and efficient algorithm called, GADT (Genetics Algorithm based Dynamics Tree) that can be used to generate...

Multicast, or one-to-many, communication arises frequently in parallel computing and telecommunication applications. Multicast networks can simultaneously support multiple multicast connections between the network inputs and network outputs. However, due to the complex communication patterns and routing control in multicast networks, there is still a considerably large gap in network cost betwe...

Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes a efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used ...

Although multicast is an important communication primitive for parallel programming, many modern networks do not support it in hardware. Multicast can be implemented in software on such networks, using some spanning tree protocol. Making multicast reliable, however, is a difficult problem, even if the hardware point-to-point communication is reliable. The key issue is that a flow control mechan...

Group communication protocols are used in fault-tolerant systems to maintain strong replica consistency. The FaultTolerant Multicast Protocol (FTMP) described here is a group communication protocol specifically designed for the Common Object Request Broker Architecture (CORBA). FTMP operates over IP Multicast, and consists of the Reliable Multicast Protocol (RMP) that provides reliable source-o...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

IP multicast technology is highly advantageous for various applications and future needs in the Internet. Yet, it is generally recognized that the IP multicast routing protocol is fairly complex and nonscalable and requires additional maintenance and operational cost to network administrators. Although there has been much research related to IP multicast and most router vendors already support ...

This paper examines the performance benefits of employing multicast communication and application-level multithreading in the Brazos software distributed shared memory (DSM) system. Application-level multithreading in Brazos allows programs to transparently take advantage of available local multiprocessing. Brazos uses multicast communication to reduce the number of consistency-related messages...
