Next-generation Internet providers face high expectations, as contemporary users worldwide expect high-quality multimedia functionality in a landscape of ever-expanding network applications. This volume explores the critical research issue of turning today’s greatly enhanced hardware capacity to good use in designing a scalable multicast protocol for supporting large-scale multimedia services. Linking new hardware to improved performance in the Internet’s next incarnation is a research hot-spot in the computer communications field. The methodical presentation deals with the key questions in turn: from the mechanics of multicast protocols to current state-of-the-art designs, and from methods of theoretical analysis of these protocols to applying them in the ns2 network simulator, known for being hard to extend. The authors’ years of research in the field inform this thorough treatment, which covers details such as applying AOM (application-oriented multicast) protocol to IPTV provision and resolving the practical design issues thrown up in creating scalable AOM multicast service models.

This book constitutes the refereed proceedings of the 6th International IFIP-TC6 Networking Conference, NETWORKING 2007, held in Atlanta, GA, USA in May 2007. The 99 revised full papers and 30 poster papers were carefully reviewed and selected from 440 submissions. The papers are organized in topical sections on ad hoc and sensor networks: connectivity and coverage, scheduling and resource allocation, mobility and location awareness, routing, and key management; wireless networks: mesh networks, mobility, TCP, MAC performance, as well as scheduling and resource allocation; next generation inte.

Master's Thesis from the year 2012 in the subject Computer Science - Internet, New Technologies, grade: 9, , course: M.TECH - Algo Networks, language: English, abstract: Abstract: Multicasting is the ability of a communication network to accept a single message from an application and to deliver copies of the message to multiple recipients at different locations. Our research in Multicasting, as to design a Multicast Model, which provides reliability & scalability with best path for data delivery. Reliability means guaranteed Delivery of packets. Scalability means capability to serve growing needs .In this context, a few concepts of Proactive-Routing technique are used to make available this model in Infrastructure wireless also. Minimum Spanning path and combo-casting is used to reduce the cost & delay and thus to deliver the packets. The main characteristic of RSM2 model is, to provide complete multicasting, i.e. at the same time more than one node can act as sender. This model provides one-to-many communications as well as many-to-many communications. The goal of thesis is to design an algorithm describing the function and behavior of Multicast Model (RSM2).

Several emerging applications of the current and next generation Internet, e.g. IP radio, IP TV, and video and audio conferencing, etc., involve one-to-many and many-to-many data communications called multicasting. Many real-time applications over IP, such as IP Telephony and video conferencing, can not operate with the best effort service provided by current IP networks. To support such applications, IP networks need to provide certain quality of service (QoS) assurances. Most of QoS-based multicast routing protocols are based on a "flat" routing model that do not scale well for large size networks. This thesis proposes QHMRP, a novel QoS-aware hierarchical multicast routing protocol. The scalability issue is addressed by organizing the network as a hierarchy of domains using the full-mesh aggregation technique. The concept of domain 'controller' is used for coordinating the creation and maintenance of multicast trees. The protocol uses a novel reverse flooding approach to connect host routers with the tree while satisfying end-to-end QoS constraints. This is a distributed algorithm, which uses only local state information at each router. The worst-case connection time and message overhead are estimated and analysis shows that QHMRP constructs loop-free multicast trees. Simulation results show that the message overhead of QHMRP is much smaller than that of the flat routing protocol using reverse flooding.
