An aggregate switch consolidates traffic from access switches, while a core switch forms the backbone of the network, interconnecting multiple aggregate switches and providing access to external networks. Core switches typically have even higher bandwidth capabilities than aggregate. Knowing the roles of core, aggregation, and access switches in contemporary network topology becomes essential to create effective and scalable networks. It is essential for larger networks requiring efficient data flow. The primary function of an aggregation switch is to aggregate and forward data from multiple network devices, such as access. Due to all traffic in a system is transmitted to the core switch, it is required to have high reliability, high efficiency, manageability, and low latency. Generally, it adopts the managed switches in the core layer.
