第4层,传输层,在该层上跑的协议,大家熟知的就是TCP和UDP.
标识源和目的网络和主机,使用的是IP,即layer 3网络层
identifies the destination network
identifies source and destination hosts
标识通过本地介质连接的设备,当然是MAC地址,即layer 2数据链路层
identifies the devices communicating over the local media
标识会话和程序的,是通过对应的端口号,即layer 4传输层
identifies the communicating applications
identifies multiple conversations between the hosts
