Installed in the middle of the network architecture, the aggregation switch is in charge of controlling the data sent from the lower layer (access layer switch), while also reporting data to the upper layer (core layer switch). As the physical part of the aggregation layer, aggregation switches typically play a crucial part in the overall network architecture. The aggregation layer serves as the convergence point for multiple access layer switches and is responsible for handling all. An aggregate switch is a high-capacity network switch that consolidates connections from multiple access switches, acting as a central point for managing network traffic and providing enhanced bandwidth capabilities. It is essential for larger networks requiring efficient data flow. This arrangement increases throughput beyond what a single relationship could sustain, offers redundancy in case one of the links.
