Learn about the OSI Layer 2. The Data Link Layer. MAC; VLAN; Encapsulation and synchronization of package frames. Including all the relevant Data link layer protocols
In the TCP/IP-based layered network, layer 2 is the data link layer. This layer is also called simply the link layer. The actual protocols encompassed in the link layer are numerous, and the implementation details can be found in various documents throug
传到第二个交换机,交换机2会去查表,表里没有且知道了从哪个端口发过来的,会更新地址表,会认为AA在交换机2的F0/2端口。然后连他的pc广播。 注意:交换机只会学习源mac地址。 AA给DD发: DD给AA回包: 交换机2收到更新地址表,然后按着MAC表转发,转发到交换机1,1的地址表更新,然后查表发给AA 如果300秒内...
Open image in new window The Data Link Layer (sometimes abbreviated to Link Layer) provides transparent transfer of data link service data units between network entities. The Physical Layer described in the previous chapter provides transparent transmission of physical service data units between data ...
【KN1】week 2-Data Link Layer -2 thinkingaboutzu 达姆施塔特工业大学 分布式软件系统硕士3. Flow Control and Error Treatment 流量控制:因为发送者发送太快、接受者相对较慢。 介绍了从简单到完善的协议: Utopia: 假设buffer无限大,接收进程无限快,传输无差错。就直接传就完事了。 Stop-and-Wait: ...
第2 层或者数据链路层(Data Link layer)机器间通信 名字:数据链路层 作用:使局域网中的机器互相连接 辅助作用:侦测传输错误 相关设备:交换机(也就是常说的 Switch) 第二层的作用是:使局域网中的机器互相连接。 数据链路层还有一个作用:侦测传输错误。 MAC 地址:
Layer 2 – Data Link Layer Thedata link layerenables the physical transmission of data. The data protocol unit name at data link layer is Frame. This layer mainly works with physical addressing (MAC address) and error notification. Ethernet, PPP, andFrame Relay, and so on are examples of ...
