The large capacity of optical fibers suggests that circuit-switching may become a more attractive switching method in future communication networks. We show, however, that under some reasonable assumptions the delays associated with circuit-switching make the technique inferior to packet-switching in a high-performance, distributed environment. A network design that demonstrates the feasibility of packet-switching in high-performance environment is also presented.

光纤的大容量表明电路交换可能会成为未来通信网络中更具吸引力的交换方法。但是,我们表明,在某些合理的假设下,与电路交换相关的延迟使该技术在高性能,分布式环境中不如数据包交换。 p> rn
