Gabriel Terhorst, in Computer Networks, 2022 2.2 Link layer The link layer (LL) handles low-level tasks like reception, processing and forwarding of protocol data units (PDUs). To achieve a responsive RF communication through the physical layer, all time-critical tasks are also done by the ...

In subject area: Computer Science The Data Link Layer is a layer in the OSI model that is responsible for controlling device interaction and addressing in a network. It combines data bits into frames and handles network topologies like Ethernet. Network switches are commonly found at this layer....
Link-layer Switches (链路层交换机) 几种常见网络设备区别 中继器(repeter):物理层设备 =>将信号放大后转发 集线器(hubs):物理层设备 =>不能隔离冲突域(集线器是一种特殊的中继器) 网桥(Bridge):二层网络设备 =>可隔离冲突域 交换机(Switches):二层网络设备 =>可隔离冲突域 ...
You may have noticed the gap between the numbering system and the conceptual model. Layer two is the data link layer. This covers communications over individual links. The easiest way to see the difference is in a network using hubs. Hubs are obsolete, thanks to the rise of switches. A hu...
In this attack, the attacker is considered a hardware intruder that deceives data link layer apparatus like the switches of layer two or three, taking advantage of a vulnerability in the MAC address table of the network nodes. That leads the network switches to send all the network traffic to...

However, when a BS switches to on/off mode in binary sleep mode, there is a transition delay between activation and deactivation time and throughput degradation. Several studies have divided BS’s sleep mode into stages to address this issue and described the energy consumption at each stage. ...
Broadcast networks have an additional issue in the data link layer: How to control access to the shared channel. A special sublayer of the data link layer, the Medium Access Control(MAC) sublayer, deals with this problem. ← Prev
