项目摘要

9314253 Hajek The principal investigator (PI) will focus on performance evaluation and design of communication networks of the future with emphasis on large, high-speed networks, both optical and electronic. The main topics are 1) Spectral Response of Queues and Diffusion Approximation, 2) Continuous Traffic in Packet Switches, 3) Multirate Circuit Switches, and 4) Optical Interconnections. The approach will be to perform modeling, analysis, and design. Models will be based on current and anticipated future technology and cover a broad spectrum of networks with circuit-switched to datagram packet networks at the extremes. Analysis will consist of a mixture of exact probabilistic methods and simulation. Design will be motivated by modeling and analysis and aided by optimization tools of both combinatorial and linear types. Finally, inequalities from information theory, mathematical physics, decision theory and combinatorics will be applied to yield new performance bounds, providing a bridge between design and performance evaluation. Successful completion of the proposed research would provide new network topologies and control strategies for high performance networks, improved means to predict performance to support the offering of guaranteed service, and techniques to extrapolate accurately performance observed for small experimental networks to large-scale networks. ***

9314253 Hajek 首席研究员（PI）将专注于未来通信网络的性能评估和设计，重点是大型高速网络（光学和电子）。主要主题是 1) 队列的频谱响应和扩散近似，2) 分组交换机中的连续流量，3) 多速率电路交换机，以及 4) 光互连。该方法将执行建模、分析和设计。模型将基于当前和预期的未来技术，并涵盖广泛的网络，包括电路交换到极端情况下的数据报分组网络。分析将包括精确概率方法和模拟的混合。设计将受到建模和分析的推动，并得到组合和线性类型优化工具的帮助。最后，信息论、数学物理、决策理论和组合数学的不等式将被应用于产生新的性能界限，在设计和性能评估之间架起一座桥梁。拟议研究的成功完成将为高性能网络提供新的网络拓扑和控制策略，改进的预测性能的方法以支持提供有保证的服务，以及将小型实验网络观察到的性能准确外推到大规模网络的技术。 ***
