the design of a highly scalable differentiated services (DS) tested and its associated network monitoring, visualization, and control (NMVC) middleware. This integrated system is designed to allow end-users, applications, and administrators to monitor, visualize, and control the performance of their quality of service (QoS) across multiple autonomous networks (AN)s by integrating (1) advanced networking hardware, (2) QoS-enabled middleware, and (3) scalable visualization algorithms to support differentiated services across ANs. This document also describes the first of a series of NMVC demonstration systems, each building on the experience gained by its predecessor. The initial demonstration system combines our real-time CORBA Audio/Video Streaming, Trading, and Naming services, Distributed Object Visualization Environment (DOVE) framework, and Distributed Object-Oriented Reliable Service (DOORS). This demonstration system will build our experience integrating these advanced components, define a rapid prototyping environment from which we can obtain valuable baseline performance and resource costs, and provide feedback on the middleware components and hooks necessary to extend the system capabilities statically and dynamically. The key benefits of our NMVC middleware are to (1) ensure adequate end-to-end QoS to applications while (2) maintaining high levels of network and endsystem resource utilization. In addition, NMVC allows network administrators to calibrate and fine-tune network and application parameters in real-time according to observed traffic patterns. These capabilities of NMVC help to ensure that network elements, middleware network services, and applications adapt efficiently to dynamically changing conditions.
