•
Each rule's bandwidth is 15/3 = 5000 Kbps.
• Since Rule 1 maximum clipping was set to 4000 Kbps, and minimum bandwidth has already
taken 2500 bytes, it will use 1500 Kbps more before reaching the maximum clipping. The
leftover 3500 Kbps (5000-1500=3500) is again given to the main pool.
•
Rule 2 does not have enough traffic coming in, so it will use only 2500 kbps (5000-2500);
the remaining bandwidth (5000-2500=2500) is again given to the main pool.
• Rule 3's input stream is 7000 bytes; it will take its share of the 5000 allocation. Still, it needs
7000-5000=2000).
•
After serving the fair share, the total leftover bandwidth is 6000 kbps (3500+2500=6000).
•
Since Rule 3 needs the bandwidth, the leftover bandwidth is applied to that rule.
•
After serving Rule 3, the leftover bandwidth 4000 Kbps will be applied to the default queue.
•
The default rule will see the data rate of4000 Kbps.
