Example 3: Stream 1 configured for VBR / BURST as follows:
: 50.00 Mbps
PCR
:10.00 Mbps
SCR
: 10.00 Cls,
MBS
CDV LIM
A fast, high-speed burst followed by a slow sustained rate and a tight CDV.
Notice that the transmission rate runs at Mbps for a very short time (equivalent to
10 cells being transmitted).
Then the transmission rate runs at 5.0 Mbps to drain the "bucket" and returns to the
SCR for the rest of the transmission queue.
The queue then immediately restarts with a high burst.
