Core switch

Core switch definition

A core switch is the primary switch in a network, built to transfer data fast. A core switch sits at the top of a network’s structure. It handles more data and offers enhanced reliability compared to other switches. The core switch acts as the main artery of a network. It ensures efficient data circulation across the network’s entirety.

Key aspects:

  • Structure: In general network setups, there are three tiers: access, distribution, and core. The core switch resides at the top. It links to distribution switches and facilitates rapid data transfer throughout the network.
  • Designed for efficiency and capacity. Core switches boast quick switching speeds and ports optimized for rapid data transmission.
  • Stability. Given their importance, core switches are engineered for consistent performance. They also come with backup mechanisms.
  • Prioritization. Core switches are tailored for speed. It often bypasses features like Quality of Service (QoS) or Access Control Lists (ACLs) to ensure prompt data relay. More intricate functionalities are typically assigned to other network switches.
  • Versatility. Besides interconnecting local network sections, core switches can also bridge to larger networks or even the internet, depending on the setup.
  • Adaptability: As network demands increase, core switches can be interconnected to cater to the augmented traffic.
