3.5.5.1.1 Network Load Control

Network load control and scalability of the enumeration process are handled by an algorithm called RepeatBAND (see section 3.5.6.2). Responders send Hello frames in the Pausing state, but they do not send them immediately. Instead, responders MUST measure the network load over a number of loosely synchronized rounds, also called blocks, of approximately fixed duration Tb (the "block time").

Section 4.4 has several examples of the RepeatBAND algorithm in effect during different scenarios.
