The growth of the Internet in recent years is resulting in a rapid increase in the demand for network bandwidth. As this growth continues, the Internet will be expected to support an increasing number of high-speed real-time applications, such as Internet telephony, video conferencing, and video distribution, which not only require significant bandwidth, but also have quality of service requirements with respect to delay and reliability of transmitted data. Recent advances in optical transmission technology and wavelength division multiplexing (WDM) systems have enabled the development of advanced communication systems which are capable of providing large amounts of bandwidth in the core of emerging telecommunications networks. Similar advances in optical switching technologies will enable the deployment of highly flexible all-optical networks in the near future. Existing optical switching technology allows for the creation of networks in which all-optical circuit-switched connections can be established end-to-end. As optical switch technology evolves, networks in which packets are switched optically at each node will become possible, offering an even greater degree of flexibility. Through the intelligent design of switch architectures and dynamic protocols, these photonic packet-switched networks have the potential to fulfill the diverse requirements of emerging broadband applications. This proposal outlines a career development plan for research and education in the area of photonic packet switching. The research plan will investigate the feasibility and suitability of photonic packet-switched networks for supporting the traffic requirements of emerging Internet applications. Emphasis will be placed on the design and evaluation of protocols and architectures for improving photonic packet network performance, while also addressing the unique physical-layer properties of optical networks. The specific objectives of the research project will be to 1) investigate protocols for resolving contention and providing differentiated levels of service in photonic packet-switched networks, 2) investigate new techniques for contention resolution in optical burst-switched networks, 3) investigate static and dynamic approaches for avoiding contention and for reducing congestion in photonic packet-switched networks, and 4) develop an integrated framework for evaluating the performance of these networks on both the physical layer and networklayer in terms of metrics such as delay, packet loss, and signal quality. This research will provide a foundation for the deployment of high-speed photonic packet-switched networks, and will identify key design parameters and trade-offs associated with the implementation of such networks. The education plan will focus on 1) developing new networking and telecommunications curriculum at both the undergraduate and graduate level, 2) organizing activities such as seminars and workshops to facilitate the transfer of knowledge from the university to surrounding industry, 3) developing new methods for providing education over the Internet, and 4) developing an outreach program to encourage under-represented minorities to seek careers in science and engineering.

近年来互联网的发展导致对网络带宽的需求迅速增加。随着这种增长的继续，互联网将有望支持越来越多的高速实时应用，如互联网电话、视频会议和视频分发，这些应用不仅需要大量的带宽，而且对传输数据的延迟和可靠性也有服务质量要求。光传输技术和波分复用（WDM）系统的最新进展使能够在新兴电信网络的核心提供大量带宽的先进通信系统的发展成为可能。光交换技术的类似进步将在不久的将来实现高度灵活的全光网络的部署。现有的光交换技术允许创建可以建立端到端全光电路交换连接的网络。随着光交换技术的发展，在每个节点上以光方式交换数据包的网络将成为可能，从而提供更大程度的灵活性。通过对交换机架构和动态协议的智能设计，这些光子分组交换网络有可能满足新兴宽带应用的各种需求。本提案概述了在光子分组交换领域的研究和教育的职业发展计划。该研究计划将调查光子分组交换网络的可行性和适用性，以支持新兴互联网应用的流量需求。重点将放在改善光子分组网络性能的协议和架构的设计和评估上，同时也解决光网络独特的物理层特性。该研究项目的具体目标是：1)研究解决争用的协议，并在光子分组交换网络中提供不同水平的服务；2)研究光突发交换网络中解决争用的新技术；3)研究避免争用和减少光子分组交换网络中拥塞的静态和动态方法。4)开发一个综合框架，以评估这些网络在物理层和网络层的性能，如延迟、数据包丢失和信号质量等指标。这项研究将为高速光子分组交换网络的部署提供基础，并将确定与实现此类网络相关的关键设计参数和权衡。教育计划将侧重于1)在本科和研究生阶段开发新的网络和电信课程；2)组织研讨会和讲习班等活动，以促进知识从大学向周边行业的转移；3)开发通过互联网提供教育的新方法；4)制定外展计划，鼓励未被充分代表的少数民族寻求科学和工程方面的职业。
