摘　　要：在介绍交换原理的基础上分析了传输技术和交换技术对通信网络容量的影响，并细致地讨论了网络瓶颈现象的变迁原因。回顾并比较了传统交换技术－电路交换、虚电路交换和数据报交换的特征及适用环境，最后详细地阐述了未来交换技术－光路交换和光包交换的工作原理及发展趋势。The paper analyzes the effects of Capacity of communication network made by the technologies of transmitting and switching. Secondly, the causes of vicissitude for network bottleneck are stated carefully.Traditional switching technologies such as circuit switching, virtual circuit switching and datagraph switching is characterized and compared and the situation adapted by them is pointed out At last the mechanism and trendancy of switching technologies in future, ie: optical circuit switch and optical packet switch, is demonstrated in detail.
