Network bandwidth that must be maintained between each Pod and layer 2 switch
Calculate the total throughput corresponding to the red, blue, and green arrows for a Pod in
"Small-scale 3-Pod configuration" (page 35).
Calculation equation
Required bandwidth (T
(Eqn. A)
+ Throughput of content display Pod sharing from each Pod to the main unit
(one blue
+ Throughput for content display Pod sharing to each Pod from main unit
(one green
= (6 Mbps × 1 + 1 Mbps × 5)
+ 6 Mbps
+ 6 Mbps
= 23 Mbps
Adding the margin of 30%, 23 Mbps × 1.3＝29.9 Mbps
Network bandwidth that must be maintained between main unit and layer 2 switch
Calculate the total throughput corresponding to the pink, blue, green, orange, and light blue
arrows in "Small-scale 3-Pod configuration" (page 35).
Calculation equation
Required bandwidth (T
+ Total throughput from Pods to main unit
+ Total throughput from main unit to Pods
+ Total for video conferencing
+ Streaming output
= (6 Mbps × 2 + 1 Mbps × 4)
+ (6 Mbps × 0 + 1 Mbps × 3)
+ (6 Mbps × 3)
+ (4 Mbps + 4 Mbps)
+ 6 Mbps
= 51 Mbps
Adding the margin of 30%, 51 Mbps × 1.3＝66.3 Mbps
Note that if a presentation is predominantly composed of still images, the throughput will be
lower and hence the required bandwidth will also be lower. Estimate the network bandwidth to
match the intended use.
