Core switch is designed to meet the most demanding enterprise network requirements such as reliability, high speed, and scalable. It supports the next-generation Ethernet speeds with 10/25 Gigabit Ethernet at the aggregation and 40/100 Gigabit Ethernet to meet the high volume of traffic driving from the edge into the core.This article provides some understanding of core switches.

What is Core Switch?
A core switch is the network switch installed at the backbone of the layered or hierarchy network. It is routing and data switching at the core layer of the network.

Three Hierarchical Inter-Networking Design
Three hierarchical inter-networking design consists of core, distribution, and access layers. A core layer switch functions as a backbone switch for LAN\WAN access and centralizes multiple aggregation devices to the core. The distribution layer switch ensures that the packets are routed between subnets and VLANs in networking. The access layer switch facilitates the connection of end-node devices, such as APs and wired devices, to the network.
In these three layers, the core switch requires most highly in the switch performance. Core switch manages high-speed connections, such as 10/ 40G/100G Ethernet.

Benefits of Using Core Switch
● High capacity
The core switch has a high capacity, which can meet the needs of data centers and work in the case of a large volume of services.
● Large cache
The core switch has distributed cache architecture, which can improve the memory of the device.
● Virtualization
The core switch can virtualize the data and convert it into resources that can be managed online.

Applications
Core switch is used in data centers, LAN/MAN/WAN, etc.

Conclusion
A core switch is used in the hierarchy Ethernet network. It facilitates strategic installation, management, and maintenance.Sun Telecom specializes in providing one-stop total fiber optic solutions for all fiber optic application industries worldwide. Contact us if any needs.
