Most enterprise networks use at least two core switches for redundancy, with larger networks employing multiple high-capacity core switches in a full or partial mesh.
The core layer serves as the high-speed backbone of a network, connecting distribution layer switches and ensuring fast, reliable data transport across the network . Core switches are designed for high throughput, low latency, and fault tolerance, and they typically avoid complex packet processing to maintain performance .
In practice, two core switches are the minimum for redundancy, while larger networks may deploy three or more core switches in a meshed configuration to ensure high availability, fault tolerance, and efficient traffic handling. The number of core switches is determined by network size, traffic demands, and the desired level of redundancy .
There are several types of network switches and understanding the differences can help you make the right choices for your small
