The convergence ratio is the ratio of switch downlink bandwidth to uplink bandwidth, and the convergence ratio between the aggregation layer and the core layer is typically 3:1 in a data center network architecture. Together, these layers can offer consumers a network that is safe, reliable, and affordable. "Feature Typical Configuration Examples" provides. Function: Connection point for all devices on a segment of segment of a network that breaks down and absorbs the data flow between all of the connected devices rather than flooding it to all connected devices. Fault Tolerance and High. An Aggregation or "Top-of-Rack" switch is designed to connect everything in a rack at high speeds, then have an even bigger pipe out to the rest of the network. The Pro Aggregation does this with it's SFP28 25Gbps ports. The campus network involving one building usually uses the two-layer architecture, that is, only the access layer and. A flexible data center design requires solid initial planning and thoughtful consideration in the areas of port density, access layer uplink bandwidth, true server capacity, and oversubscription, to name just a few.
