CAREER: Flow Control and Traffic Modeling: A Rigorous Approach Toward Network Management

NCR-9502582 Konstantopoulos，Takis 这是一个关于开发一个严格的方法来进行网络管理和性能分析的高速网络，考虑到网络管理系统的局部和全局方面的建议。 本地方面包括在网络边缘处的流量控制器的设计，该流量控制器考虑到服务质量的提供和网络交换机中用户之间的交互。 调查人员将扩展最近开发的技术，这些技术是基于所谓的反射映射，开发测试技术和模拟，并将其与现有的计划进行比较。 研究人员还将研究交通建模。 他将开发严格的方法来验证从综合服务高速网络的操作中产生的自相似流量过程，并使用这些模型来建立性能分析方法。 研究一个管理系统的全球方面涉及到使用一个宏观的网络图片目前正在开发的调查。 这幅图去掉了网络运行的细枝末节，同时保留了它的动态特征（它不是静态的）。 研究人员建议网络管理系统使用这样的图片，以预测、预防和纠正可能导致网络服务降级的不良行为。

NCR-9502582 Konstantopoulos, Takis This is a proposal about the development of a rigorous approach toward network management and performance analysis for high-speed networks considering local and global aspects of a network management system. Local aspects include the design of flow controllers at the edges of the network that take into account the provision of quality of service and the interaction between users in a network switch. The investigator will extend recently developed techniques that are based on the so-called reflection mapping, develop testing techniques and simulations, and compare these to existing schemes. The investigator will also study traffic modeling. He will develop rigorous methods for validating self-similar traffic processes arising from the operation of an integrated services high-speed networks and use such models in establishing performance analysis methods. Studying the global aspects of a management system involves using a macroscopic picture of the network currently being developed by the investigator. The picture strips out the minutiae of the operation of the network, while retaining its dynamic character (it is not static). The investigator proposes the use of such a picture by a network management system in order to predict, prevent, and correct undesirable behavior that might lead to degradation of services across the network.
