设想一下今天的Pentium级应用软件在几年前才使用的老386微处理器上运行情况.有些应用软件运行得那么慢,以至您在等待出结果时可以去吃饭.另外一些应用软件因受存储器的限制,根本就不能运行.今天的LAN性能与此有点相似、今天的主干LAN技术对于用户在今后五年增加的应用将不能胜任.为了与新应用的发展并驾齐驱,LAN的千兆比速度将是必不可少的.很多趋势正在成为增加LAN通信量的因素.多媒体、视频和intranet应用是经常被引证的驱动因素.然而,没有单一的因素会驱使我们去满足提高速度的要求.相反,半导体技术的不断进展却允许提高性能水平.这种按GordonM00re定律所描述的改进,允许每两年或三年以相同的价格使性能提高三倍.
Imagine today’s Pentium-class applications running on the old 386 microprocessor, which was only used a few years ago. Some applications run so slowly that you can eat while waiting for results. Some other applications suffer from memory LAN performance today is somewhat similar to today’s backbone LAN technology for users in the next five years will not be able to increase the application to keep pace with the development of new applications, LAN Gigabit speed will be Is a must. Many trends are becoming a factor in increasing LAN traffic.Multimedia, video and intranet applications are the most frequently cited drivers.However, there is no single factor that drives us to meet the demand for speedup.On the contrary, semiconductors While advances in technology allow for higher levels of performance, this improvement, described by the Gordon-Murre law, allows performance to be tripled at the same price every two or three years.
