TCP/IP协议采用4层结构,分别是应用层、传输层、网络层和链路层,每一层都呼叫它的下一层所提供的协议来完成自己的需求。由于大部分时间都工作在应用层,下层的事情不用操心;其次网络协议体系本身就很复杂庞大,入门门槛高,因此很难搞清楚TCP/IP的工作原理,本文通俗的解析一个主机的数据要经过哪些过程才能发送到对方的主机上。
TCP / IP protocol using four-tier structure, namely the application layer, transport layer, network layer and link layer, each layer calls its next layer to provide the agreement to complete their needs. Because most of the time working in the application layer, the underlying things do not have to worry about; Second, the network protocol system itself is very large and complex, high barriers to entry, it is difficult to figure out the working principle of TCP / IP, the popular analysis of a host of data To go through what process can be sent to each other’s host.
