We are conducting a series of experiments that will lead to the development of policies for adaptability at the application, system, and network layer to meet the quality of service requirements. We are conducting experiments that study the impact of various applications on the network/communication resources. Next we study the impact of network constraints in determining the quality of service that can be guaranteed to the user. Based on these experiments, we identify guidelines and expertise that will allow the applications and network to meet the quality of service requirements at all layers. We focus on three fundamental research problems: quality of service provisioning and control; policies for efficient and reliable transmission of multi-media data; and expert rules/guidelines for adaptability and its impact on various applications. This allows the research on the behavior of communication software which is suitable for next-generation Internet and its impact on various emerging applications such as multimedia, digital libraries, and video conferencing systems. This research provides advanced network services, protocols, techniques and their experimental evaluation. This enables researchers in building integrated-service communication subsystems that satisfactorily implement applications requiring different levels of quality of service. This knowledge is applicable to various system software used in collaborative computing, distributed file systems, multimedia application, and real-time processing.
