You need to have specifications that detail the target traffic flows, to select the appropriate switch for a layer in a hierarchical network,
Traffic flow analysis is the process of measuring the bandwidth usage on a network and analyzing the data for the purpose of performance tuning, capacity planning, and making hardware improvement decisions
