How to plan and calculate the bandwidth of the link between WLC, CMX and DNAC?

[yaoszhan]

 If customer require a network deployment, DNAC is deployed in data center, WLCs and CMXs are deployed different sites across country? How to plan and calculate the bandwidth of the wan link between them? Do we have the guide on this? How to plan and calculate the bandwidth of the link between CMX and DNAC? How to plan and calculate the bandwidth of the link between WLC and DNAC? How to plan and calculate the bandwidth of the link between CMX and WLC?

For cmx, would consider it similar to DNA spaces and WLC, Look at table 2 and 3 from link below.

for DNAC refer time this document

Thanks Ammahend, 

  Good advise.  I still look for the bandwidth estimation between DNAC and WLC or switch.

bandwidth is often refereed as point to point, so I am not sure if it would be a good metric for a connection which transverses multiple networks or service providers. Round trip time is a more sustainable estimate for such situations since its end to end. In the link I shared it talks about RTT between DNAC to all device types e.g. ISE or WLC or switches etc. see enclosed.
