telnet route-server.ip.att.net
最近在写流量工程的东西,就是做一个开学以来对这些东西的总结啦,已经写一些了,准备过一段时间发布到blog上来~着手开始写QOS,!!!前几天累得不行,在和秋月去大力嘉的车上,路上都在想这个问题,现在可轻松多了,刚刚,忙完年级网站(http://mcs.fjnu.edu.cn/mcs2002/) 不知道外网能不能看哈~~,如果可以看到,可以在相关留言簿上发表看法哈~
做很多事情心态很重要,就像dt说的一样:
如果你可以认真做好一枚别针，你赚的钱会比你制造出一台丑陋的蒸气机还要多...
如果做事都可以有这样的心态,那我们可以保持很好的心情,可以把事情做好,不要对那些所谓的编程高手对学网络的不屑所动摇自己的决心.坚持!!!
下面据说是Internet backbone的路由器的路由哦~看看哈!!!
也可以免费登陆的!!!

Ping and traceroute delay figures measured with this box are unreliable,
due to the high CPU load this box experiences when complicated "show" commands
are being executed.
