这是中国最早的网络信息. "Across the Great Wall we can reach every corner of the world" .

对中国这是一个时代的开始: 1987年9月14日北京时间21点07分. 网络世界来自于中国的第一份电子邮件是用英文和德文这样开始的: "越过长城我们能够到达世界所有的角落".

这是从机械部国家电脑应用研究中心发往德国 Karlsruhe 大学计算机研究中心的一份电子邮件. 由于当时 main frame 和 unix 上采用 uucp 来传递电子邮件, 一直到6天后德国方面才收到.

这份电子邮件标志着一个新时代的开始. 短短的二十来年, 网络为中国社会带来了翻天覆地的变化. 我们有幸见证了这一科技的奇迹.

许多年前笔者在德国的普郎克研究所从事研究工作的时候开始接触互连网技术.

科技的创新和生产力的进步才是人类社会进步真正的推手. 今天中国政府对网络施加各种不应该有的限制. 当我们回顾网络的发展和在中国的普及, 我们还记得这一份来自中国最早的网络信息吗?

"越过长城我们能够到达世界所有的角落"

At the pre-scheduled date and time, the UUCP system would activate the modem to make a long distance phone call and connect to the remote host. Depended on how the system administrator set up the system, and also depended on how many intermediate systems the message needed to traverse through, it could take a long time. Sounds unbelievable right?

john.doe@abc!milkway!beattheodd!forgetme!cde

1) in most of scenarios, emails are still saved in spools at the last hop of emails servers until one fetches his.her mails.
2) back then, there were no full scale internet yet. so-called internet was purely point-to-pont:unix servers to unix servers. if no one checks the mail spool, emails would sit there forever...

routing protocols were born with tcp/ip protocols!!!

the way of emails shows that way gotta nothing to do with routing protocols!!!

The email header has all the timestamps. You can take a look at it by yourself. Unless, one side's clock was set wrong.

back then there were very few long haul links and there were no "professional" routers. every thing was hop by hop. if one hop didn't do anything (i.e., didn't relay the email), then that email sat there until someone did something with modem and sent it to next hop...

The first PC email clients were written by one of my friends; The first oversea chinese input software BYX (下里巴人 by 严永欣); The first unix X term chinese input software; The first chinese news group; The first oversea chinese website: CND. I was working at University of Chicago and put together a BOT tool that visits all major chinese web sites in far eastern to grab newspaper articles and forward them to CND.
