Communication environments are becoming increasingly heterogeneous. This imposes new challenges on communication support for multimedia and collaborative applications. AMnet (Active Multicasting Network) provides multi-point communication support for large-scale groups with heterogeneous receivers. Active Multicasting nodes inside the network include so-called QoS filters that remove informatio...

A scalable QoS aware multicast deployment in DiffServ networks has become an important research dimension in recent years. Although multicasting and differentiated services are two complementary technologies, the integration of the two technologies is a non-trivial task due to architectural conflicts between them. A popular solution proposed is to extend the functionality of the DiffServ compon...

Mobile agents compete with multicasting for applications in distributed military systems. Systems such as unmanned aerial vehicles (UAVS) and automatic target recognition (AiTR) devices utilize intelligent agents to sense the environment and make decisions regarding reporting or firing on a target. Mobile agents migrate between these distributed components and assist in the learning and deducti...

Recent advances in multicasting present new opportunities for improving communication performance for clusters of workstations. Realizing collective communication over multicast primitives can achieve higher performance than over unicast primitives. However, implementing collective communication using multicast primitives presents new issues and challenges. Group management, which may result in...

In this paper, we address the problem of multicasting in military “ad-hoc” wireless networks. Since such networks lack a fixed cellular infrastructure, multicast algorithms that are based on the availability of fixed, known topologies cannot be used effectively. Even when lhe locations of the nodes are fixed and known, the properties of the wireless medium create a networking environment that i...

Despite its obvious suitability for distributed multimedia applications, multicasting has not yet found widespread application. Having analyzed shortcomings of today's approaches, we devise in the GCAP project a new endto-end transport architecture for multimedia multicasting that supports partial order and partial reliability. In this paper, we argue that, at the network layer, single-source m...

The significant growths of group communications and QoSaware applications over the Internet have accelerated the development of two key technologies, namely, multicasting and Differentiated Services (DiffServ). Although both are complementary technologies, their integration is a non-trivial task due to several architectural conflicts between them. The inherent heterogeneous nature of QoS multic...
