In this thesis, we will present solutions for end users on how to profit from efficient data transmission and dissemination using multicasting with Quality of Service (QoS) support. Multicasting is one of the most efficient mechanisms to distribute data from one sender to multiple receivers concurrently. Since IP Multicasting is not widely deployed in the Internet today, Overlay Multicast has b...

The allocation of router resources among competing multicast ows is an open question. In this paper, we introduce a hierarchical multi-cast scheduling protocol in which each router independently prioritizes multicast packets based upon the number of downstream receivers interested in listening to the multicast stream. We describe our protocol design and evaluate the protocol's scalability, opti...

This paper presents a performance analysis of topological and geographical multicast routing algorithms for mobile wireless ad hoc networks. Flooding and On-Demand Multicast Routing Protocol (ODMRP) are simulated and compared with two novels protocols proposed: Topological Multicast Routing Protocol (ToMuRo) and Geographical Multicast Routing Protocol (GeMuRo) in pedestrian and vehicular scenar...

The Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the protocols used by hosts and multicast routers to exchange their IP multicast group memberships with each other. This document describes ways to achieve IGMPv3 and MLDv2 protocol optimization for mobility and aims to become a guideline for the tuning of IGMPv3/MLDv2 Queries, timers, and counter values.

This paper studies the performance of an application layer multicast protocol, namely Adaptive Overlay Multicast (AOM) protocol. We introduce the concepts of fan-outs and foster limit in building application layer multicast tree, and exemplifies the performance and adaptability characteristics of AOM to network dynamics with extensive simulation results.

Multicast address assignment is a limiting factor in multicast deployment, and previous research has shown that dynamic prefix-based addressing outperforms other models. In this paper we expound on the requirements for a scalable IPv6 multicast address allocation protocol, compute thresholds for security policies, and detail our protocol DAOMAP, which fulfills our listed requirements.

OVERLAY MULTICAST FOR REAL-TIME DISTRIBUTED SIMULATION This report provides a top-level architecture for an overlay multicast service in support of distributed real-time virtual simulations over an open network environment. The top-level architecture for the overlay protocol was developed based on key concepts identified in the laboratory performance studies, the analytical model, and the studi...

A Cartesian network is a modified two-dimensional mesh network consisting of horizontal and vertical networks. At present, two 'traditional' protocols exist for the network: a unicast protocol, and a loop-free broadcast protocol. With the increasing number of multicast applications, there is a clear need for Cartesian Networks to support multicast communications. This paper presents three Carte...

The Multicast Dissemination Protocol (MDP) provides reliable multicast file and data delivery on top of the generic UDP/IP multicast transport. Early work on MDP was deployed across the global Internet Multicast Backbone (Mbone) as part of the publicly available Image Multicaster (IMM) application. This paper describes more recent work on MDP resulting in the MDP version 2 (MDPv2) toolkit. This...
