This proposal deals with the dynamic control of large networks that integrate real-time and non-real-time applications with heterogeneous Quality-of-Service (QoS) requirements. To meet these requirements, adaptive algorithms are needed for the routing, scheduling and admission control components. Routing provides a selection of routes, which should have sufficient resources to satisfy the applications' QoS. Scheduling allocates link resources (bandwidth, buffers, etc.) among the different service classes. Admission accepts or rejects a new incoming application, based on the requested QoS and the available resources. Because each control component causes and reacts to changes in the network state, there is a strong time-dependent interaction among them. By taking this interaction into account, the proposed work will develop QoS routing algorithms that will provide significant improvements in performance. To this end, we will develop dynamic integrated models. A novel numerical-analytical technique, called "Z-iteration", will be used to solve these models. The Z-iteration promises to provide rapid and accurate solutions to transient performance of integrated networks consisting of both wired and wireless links. Networks based on ATM and integrated services IP will be considered. The proposed work will develop software educational tools and projects for integrated networks, and will experiment with providing QoS support to educational multimedia applications.

该提案涉及对大型网络的动态控制，这些网络将实时和非实时应用程序与服务质量（QoS）要求（QoS）的要求集成在一起。 为了满足这些要求，需要自适应算法来进行路由，调度和入学控制组件。 路由提供了一系列路线，该路由应该具有足够的资源来满足应用程序的QoS。 计划在不同的服务类中分配链接资源（带宽，缓冲区等）。 根据请求的QoS和可用资源，入学接受或拒绝新的传入申请。 由于每个控制组件都会导致网络状态变化并反应，因此它们之间存在很强的时间依赖性相互作用。 通过考虑这种互动，拟议的工作将开发QoS路由算法，从而提供大幅改进性能。 为此，我们将开发动态的集成模型。 一种称为“ z透度”的新型数值分析技术将用于解决这些模型。 Z材料有望为包括有线和无线链接组成的集成网络的瞬时性能提供快速准确的解决方案。 将考虑基于ATM和集成服务IP的网络。拟议的工作将开发用于集成网络的软件教育工具和项目，并将试验为教育多媒体应用提供QoS支持。 有关此项目的更多信息，请参见http://www.ccs.neu.edu/home/matta/proj/proj/project.html
