The simple answer is when that is the behavior you want :)
It is interesting though to look at what that actually does though.
Starting off looking at generic shaping configured with MQC.
Shape average has a burst setup that allows the Be amount of bits to be
sent in addition to the Bc amount of bits on the first interval of a
second.
Shape peak allows Be amount of bits to be sent along with Bc amount of
bits at every time interval.
Frame shaping behaves like the shape average, in that Be is only sent on
the first interval.
So really if you want to have an additional burst of say 1000 bits per
second, configure FRTS with a Be of 1000, as this will allow the shaper
to send an additional 1000 bits once per second on the first time
interval.
I have seen solutions to questions that have Be = Bc for FRTS when the
requirement is to have the burst rate equal to the committed rate, but
that I believe is incorrect. As Be is only added on the first time
interval and not on every time interval, that would not work.
