The demand for access layer switches is the largest, and the layer 2 network switch connected to the terminals need to meet the multi-port and low-cost characteristics, so the main consideration is the cost-effectiveness factor.
Because of its position, its performance must ensure that the access layer is higher and the switching speed is faster to meet the needs of upload and download. So need more ports and better performance.
When choosing a core switch, you should focus on comparing the throughput, bandwidth, and other factors of the switch, and choose a manageable switch with a Gigabit or even 10 Gigabit or more.
