1. **bits(物理层)**:数据以比特流的形式通过物理介质传输。 2. **frame(数据链路层)**:比特被封装成帧(例如以太网帧),包含MAC地址等信息。 3. **packet(网络层)**:帧解封为IP数据包,处理IP地址和路由。 4. **segment(传输层)**:数据包进一步拆分为TCP/UDP段,包含端口号和传输控制信息。

当数据再被往下传输的时候,就变成了packet,即“包”的意思。在这一层,Segment会被加上IP头部信息,然后就可以在三层传输了,而工作在三层的路由器会根据目的IP地址来转发这些”包“。 在往下,数据就会被加上MAC地址信息,名称就变成了Frame,”帧“。在这一层,就是交换机的世界了,交换机通常查找MAC地址表项来转发...
