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。 5. **data(应用层)**:最终的应用数据(如HTTP、FTP等)。
bitframepa..datagram(数据报) – 在网络层中的传输单元(例如IP)。一个datagram可能被压缩成一个或几个packets,在数据链路层中传输。 packet(数据包) – 封装的基本单元,它穿越网络
根据OSI七层模型,一个数据包的封装过程为bit—frame-packet—data-segment。( ) A、正确 B、错误 查看答案
数据链路层协议数据单元PDU俗称为___。(补充知识:PDU的全称是Protocol Data Unit即协议数据单元。PDU是指对等层次之间传递的数据单位。物理层PDU是数据位(bit),数据链路层的 PDU是数据帧(frame),网络层的PDU是IP数据报(packet),传输层的 PDU是数据段(segment),其他更高层次的PDU是数据(data)。(提示:PDU在概述...

In addition, due to high bit error rate and severe packet loss in underwater acoustic communication, traditional routing protocols need to continually retransmit packets, which further increases the network overhead. In this context, opportunistic routing is proposed to enhance data transmission without...
