PPPoE represents a point-to-point protocol on the Ethernet. It is a network tunnel protocol that encapsulates the point-to-point protocol (PPP) in the Ethernet framework. It enables Ethernet hosts to connect to a remote access concentrator via a simple bridging device.Us...

POE power supply is achieved through the network cable, and the network cable is composed of four pairs of twisted pairs (8 core wires), so the eight core wires in the network cable are the PoE switch to provide data and power transmission media for the receiving device....

Step 1: Detect the receiving device (PD). It is mainly to detect whether the connected device is a real receiving device (PD) (in fact, it is to detect the receiving device that can support the Power over Ethernet standard). The PoE switch will output a small voltage at ...

Under the development trend of the Internet of everything to build a smart world of things, users' demand for IoT devices is increasing, and POE switches have become an effective medium to provide power and data transmission for PD devices through network cables. PoE swi...

With the deployment and implementation of the optical transformation of broadband network, the network quality is improved, the failure rate is reduced, and the user's favorable impression is increased. At present, the formation of broadband access network is dominated b...

The core layer switch is mainly used for route selection and high-speed forwarding, providing an optimized and reliable backbone transmission structure, so the core layer switch application has higher reliability and throughput. The aggregation layer switch is the conver...
