The difference between the core switch and ordinary switch: usually will direct user oriented connection or network access part of the network access layer is called, will be located between the access layer and core layer called the distribution layer or the convergence layer, the access layer is designed to allow the end user to connect to the network, so the access layer switch has the advantages of low cost and high port density characteristics; aggregation layer switch is multiple access layer switches together, it must be able to handle all the traffic from access layer equipment, and provide the uplink core layer, the convergence layer and access layer switch switch, need higher performance, less interface and higher exchange rate. The main part of network as the core layer, the core layer is the main purpose of communication through high-speed forwarding, optimization, providing reliable backbone transmission structure, so the core switch application reliability, performance and higher throughput.

Computers to achieve a certain number will be used on the core switch, and basically no need to use the core of the following 50 core switches, there is a router can be. The so-called core switches for network architecture, if a few computer small LAN, a 8 small switch can be called the core switch! And in the network industry core switch refers to the network management function, throughput of powerful 2 or 3 layer exchange machine, a more than 100 Taiwan computer network, if you want to stable and high-speed operation, the core switch is essential.
