The Services Provided by the Link Layer(链路层所提供的服务) 链路层所提供的最基本的服务就是在两个相邻节点见得单个通信链路上转移datagram 成帧(Framing) 在发送端将构造数据帧,将datagram放入数据域,加头加尾(尾部是用来检测及纠错的),打包成帧 在接收端解开收到的数据帧,将datagram传递给上层 链路接入(Link...
The Data Link Layer, which is the second layer in the communication protocol stack, has two sub-layers: the Medium Access Control (MAC) sub-layer, which sits on top of the Physical Layer, and the Logical Link Control (LLC) sub-layer, which interfaces the DLL with the upper layers. ...

One of the primary purposes of this layer is to essentially abstract away the need for any other layers to care about the physical layer and what hardware is in use. By dumping this responsibility on the data link layer, the Internet, transport and application layers can all operate the same...
