The double leaky bucket meter, shown in figure 2.3, is similar to the single leaky bucket meter. The only differences are that tokens must be simultaneously available in two distinct buckets, and that tokens are removed from both buckets if the packet is found to be conforming.
DLB has the following parameters:
|cbs||Bytes||Committed burst size|
|cir||bps||Committed information rate|
|mpu||Bytes||Minimum policed unit|
|pbs||Bytes||Peak burst size|
|pir||bps||Peak information rate|
Only mpu is optional, all other parameters are required.
The functions for testing a double leaky bucket meter are described in the previous section.
