Using Generic Traffic Shaping
and Frame Relay Traffic Shaping
.. FRTS and GTS both use a token bucket, or credit manager, algorithm
to service the main queuing mechanism and send packets out the
interface. FRTS is commonly used to overcome data-rate mismatches.
.. FRTS and GTS act to limit packet rates sent out an interface to a mean
rate, while allowing for buffering of momentary bursts.
.. Recall that queuing mechanisms will only kick in when there is
congestion, so we need a mechanism to create congestion at the headend.
This is a common need on Frame Relay networks where the home
office has much more bandwidth than any individual remote office.
