每当看到有人的简历上写着熟悉 tcp/ip, http 等协议时, 我就忍不住问问他们: 你给我说说, 端口是啥吧! 可惜, 很少有人能说得让人满意... 所以这次就来谈谈端口(port), 这个熟悉的陌生人. 在此过程中, 还会谈谈间接层, naming service 等概念, IoC, 依赖倒置等原则以及 TCP ...

Well, if you consider the application layer as part of the suite, then I supposed it IS part of the TCP/IP suite. You certainly don't see HTTP implemented over IPX - or at least I haven't.
