中文摘要： 网络接口的高速化、信息交换的海量化、网络业务的多样化发展对传统的路由交换设备的交换能力和服务质量提出了新的挑战,交换技术作为路由交换设备中的关键技术成为制约互联网发展的瓶颈之一。从这一背景出发，本课题结合国内外该领域最新研究现状，依托所在单位的工程理论基础，进行交换技术的关键基础理论研究。本课题引入自适应负载均衡的概念，动态调整流量在交换系统内的路径取向，达到流量在交换系统内负载均衡的目的，以解决现有交换技术存在的问题，具体着重研究如下三个方面的问题：一是针对现有交换机制存在的不足，设计一种自适应负载均衡的交换调度算法；二是基于负载均衡交换机制，研究公平交换准则和评价准则，并设计自适应公平交换调度机制；三是研究复杂网络业务环境下（单播、组播、实时业务）交换机制的吞吐量、时延和服务质量的优化问题。本课题旨在通过交换技术的研究丰富和完善交换技术基本理论，指导满足网络发展需求的交换系统的设计。

英文摘要： With the trends that the network interfaces are developing into high-speed, the switching capacity is increasing continually, and the emerging of various new applications, the switching technology, which plays an important role in the routing and switching equipment, are facing great challenges and becoming one of the bottlenecks in today's internet. Departure from the background, combined with the latest research progress in the literature and the current theoretical and technical innovations we have achieved in in this field, we will conduct the key fundamental research on switching technologies. To solve the current problems, the adaptive traffic load balancing concept is introduced and the paths for traffic are dynamically adjusted internal the switch. In this way, the traffic arriving at the switch will be load-balanced. Our studies will concentrate on the following three aspects. Firstly, due to the deficiencies of current switching technologies, an adaptive load balancing switching and scheduling scheme will be designed. Secondly, based on the new scheme, we will set up fair switching principle and its' evaluation principle. Under these principles, an adaptive and fair switching scheme will be proposed. Thirdly, we will focus on the throughput, delay and QoS (Quality of Service)'s optimization of switchin
