Calculation equation of throughput from main unit to Pods
Calculate the throughput corresponding to the green arrow in "Network bandwidth diagram for
active learning" (page 22).
Required bandwidth = Throughput of content display Pod sharing from main unit to a Pod
(T )
pod_content
× Number of Pods (N
= 6 Mbps × 1
= 6 Mbps
From the above calculation equation, the required network bandwidth that must be maintained
between Pod and layer 2 switch is given below.
Required bandwidth (T
× Number of Pods
+ Total throughput from Pods to main unit
+ Total throughput from main unit to Pods
= 7 Mbps + 6 Mbps + 6 Mbps
= 19 Mbps
Adding the margin of 30%, 19 Mbps × 1.3＝24.7 Mbps
