What Does Core Switch Mean?

A core switch is a high-capacity switch generally positioned within the backbone or physical core of a network. Core switches serve as the gateway to a wide area network (WAN) or the Internet – they provide the final aggregation point for the network and allow multiple aggregation modules to work together.

A core switch is also known as a tandem switch or a backbone switch.

Techopedia Explains Core Switch

In a public WAN, a core switch interconnects edge switches that are positioned on the edges of related networks. In a local area network (LAN), this switch interconnects work group switches, which are relatively low-capacity switches that are usually positioned in geographic clusters.

As the name implies, a core switch is central to the network and needs to have significant capacity to handle the load sent to it. There isn’t a precise definition as to how powerful this is, but clearly it is much bigger than an average desktop switch.

What Is Core Switch?

If we spend some time looking up dictionaries for the meaning of core switch, we will find a definition similar to “A core switch is a high-capacity switch generally positioned within the backbone or physical core of a network. Core switches serve as the gateway to a wide area network (WAN) or the Internet—they provide the final aggregation point for the network and allow multiple aggregation modules to work together (An excerpt from Techpedia).” The definition explains its high-capacity feature, the physical location and its function of connecting multiple aggregation devices in network.

A core switch, also known as a tandem switch and a backbone switch, is a high-capacity switch positioned in the physical core, or backbone, of a network. In a public Wide Area Network (WAN) a core switch serves to interconnect edge switches, which are positioned at the network edge. In a Local Area Network (LAN), a core switch serves to interconnect workgroup switches, relatively low capacity switches that serve groups of workers in geographic clusters. See also switch.
