  • The Role of Aggregation 10 Gigabit Layer Switches

    The Role of Aggregation 10 Gigabit Layer Switches

    The aggregation layer serves as the convergence point for multiple access layer switches and is responsible for handling all the communication traffic from the access layer devices and providing uplink connectivity to the core layer. Together, these layers can offer consumers a network that is safe, reliable, and affordable. It facilitates the connectivity because it would rapidly become impractical to. The aggregation (sometimes also called distribution) layer is a real crossroad.
