Design, Performance Evaluation and Implementation of New Network Architectures for High Speed Optical LANs: Tree Networks with Collision Avoidance

苏达教授将研究一类新的使用冲突避免交换机的局域网体系结构。这些交换机允许实现随机访问协议，而不会造成分组之间的冲突。它们结合了随机接入的优点(即，流量较少时的低延迟；简单的分布式，因此具有健壮的协议)与出色的网络利用率和传输的并发性。在这个研究项目中，首席研究员将通过分析和仿真来研究(1)站点协议和交换结构的几种变化，(2)使用光子器件的交换机的设计和原型实现，以及(3)网络体系结构的性能(例如，延迟和吞吐量)。

Professor Suda will investigate a new class of local area network architectures that use collision avoidance switches. The switches allow the implementation of random access protocols without the penalty of collision among packet. They combine the benefits of random access (i.e. low delay when traffic is light; simple distributed, and therefore robust protocols) with excellent network utilization and concurrency of transmission. In this research project, the principal investigator will investigate (1) several variations for station protocols and switch architectures, (2) design and prototype implementation of a switch using photonic devices, and (3) performance (e.g. delay and throughput) of the network architectures through analysis and simulations.
