Aggregation switches also require relatively high forwarding performance and are typically Layer 3 switches. This article looks at what each such tool does, compares how they differ from each other, and offers suggestions as to what sort of network each. Core switches and aggregation switches serve different purposes, have distinct characteristics, performance requirements, and are suited to different use cases. A core switch is primarily responsible for routing and fast forwarding, providing a highly reliable and optimised backbone transmission. As the aggregation point of access switches, the aggregation switch is required with the ability to process the access layer information and submits it to the upstream chain of the core layer. And it needs the function of network isolation and segmentation as well.
