Bandwidth requirements for Splunk

[evinasco08]

hi team

What minimum bandwidth is necessary between indexers and the rest of the platform elements (Heavy Forwarders, Search Heads, Master Cluster, License, Deployment Servers, etc.) for different communications?

It truly depends on many factors, like number of events, number of forwarders, as well as stakeholder expectations/requirements, and how much time and money you have!
