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

NCR-9502582 Konstantopoulos，Takis这是一项关于开发一种严格的网络管理方法和高速网络性能分析的建议，该方法考虑了网络管理系统的局部和全局方面。局部方面包括在网络边缘设计流量控制器，该流量控制器考虑了网络交换机中服务质量的提供和用户之间的交互。研究人员将扩展最近开发的基于所谓反射映射的技术，开发测试技术和模拟，并将这些技术与现有方案进行比较。调查员还将研究交通建模。他将开发严格的方法来验证综合业务高速网络运行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。研究管理系统的全球方面涉及使用调查员目前正在开发的网络的宏观图景。这幅图剥离了网络运行的细节，同时保留了它的动态特征(它不是静态的)。调查者建议网络管理系统使用这样的画面来预测、防止和纠正可能导致整个网络上的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.
