​The difference between a core switch and a common switch Apr 14, 2017

The difference between a core switch and a common switch:
Typically, a portion of a network that connects directly to a user or accesses a network is called an access layer.
The portion of the access layer and the core layer is referred to as the distribution layer or convergence layer, the access layer is designed to allow end users to connect to the network, so the access layer switches have low cost and high-end port density characteristics; Convergence layer switches are the convergence points of multiple access layer switches. It must be able to handle all traffic from the access layer devices and provide uplink to the core layer, so the convergence layer switches compare with the access layer switches, requiring higher performance, fewer interfaces, and higher exchange rates. And the backbone of the network is called the core layer, the main purpose of the core layer is to transmit high-speed communication, to provide optimized and reliable backbone transmission structure, so the core layer switch applications have higher reliability, performance and throughput.
The computer reaches a certain amount to use the core switch, and basically below 50 units without using the core switches, there is a router. The so-called core switches are for network architecture, if it is a small LAN of several computers, a 8-mouth small switch can be called the core switches! In the network industry, the core switches are network management function, the throughput of a powerful 2-storey or 3-tier switches, more than 100 computer networks, if you want to stabilize and high-speed operation, the core switches are indispensable.
