*This round is triggered immediately upon entering the Pausing state when a new session is created and the session table was previously empty.

In this scenario, the small number of frames seen during each block does not have any overall effect in slowing down the sending of the Hello frame. This is acceptable since the chance of congesting the network is small with the low volume of traffic being generated.
