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.

该建议涉及大型网络的动态控制，集成实时和非实时应用与异构的服务质量（QoS）的要求。 为了满足这些要求，需要自适应算法的路由，调度和接纳控制组件。 路由选择提供了一个路由选择，这些路由应该有足够的资源来满足应用程序的QoS。 调度分配链路资源（带宽、缓冲区等）在不同的服务类别中。 Admission根据请求的QoS和可用资源接受或拒绝新的传入应用程序。 由于每个控制组件都会引起网络状态的变化并对其做出反应，因此它们之间存在强烈的时间相关交互。 考虑到这种相互作用，拟议的工作将开发QoS路由算法，将提供显着的性能改善。 为此，我们将开发动态综合模型。 一种新的数值分析技术，称为“Z-迭代”，将被用来解决这些模型。 Z迭代有望为由有线和无线链路组成的综合网络的瞬态性能提供快速准确的解决方案。 将考虑基于ATM和综合业务IP的网络。拟议的工作将开发软件教育工具和项目的综合网络，并将试验提供QoS支持的教育多媒体应用。 有关此项目的更多信息，请访问http://www.ccs.neu.edu/home/matta/proj/project.html
