每天早晨来到办公室的第一件事,就是给笔记本电脑插上电源、插上网线,然后开机。若干年后,有以太网的地方也许只要插上网线就可以开机。因为以太网不仅可以供电,而且未来几年供电功率有望超过目前的13W,并达到笔记本电脑的功耗要求。“第一英里”以太网在铜线上突破100m的传输距离,达到了1.5km,已经可以铺到人们的家门口,让每个家庭都能体验以太网的力量。这还不算完,未来几年家里也可以铺设适合多媒体应用的以太网,家庭以太网标准正在酝酿中。其实,早在“第一英里”以太网之前,以太网仅仅是局域网的观念就已经被打破,万兆标准就把以太网扩张到了城域网。现在,以太网还要延伸到广域网。……尽管以太网已经走过了31年的历史,2004年11月12日由《网络世界》主办的“以太网世界2004”大会仍然为人们带来了耳目一新的以太网最新技术。
The first thing that comes to your office every morning is to plug your laptop into the network, plug it in, and turn it on. A few years later, there may be a place with Ethernet network cable can be switched on. Because Ethernet can not only supply power, but also power supply in the next few years is expected to exceed the current 13W, and meet the power consumption requirements of notebook computers. “First mile” Ethernet over copper 100m transmission distance, reached 1.5km, has been shop to people’s homes, so that every family can experience the power of Ethernet. This is not too far off. In the coming years, Ethernet can also be deployed at home for multimedia applications. The standard of home Ethernet is under discussion. In fact, as early as the “first mile” before the Ethernet, Ethernet is only the concept of LAN has been broken, Gigabit standards put Ethernet expansion to the MAN. Now, Ethernet also extends to the WAN. ... Despite Ethernet’s 31-year history, the “Ethernet World 2004” conference, hosted by Networkworld on November 12, 2004, continues to bring refreshing newest Ethernet technologies to the world.
