The bucket is a buffer of packets. So if you have bucket full with tokens,
you can send some packets very fast. The rate determines the speed that new
tokens are put in the bucket. Without a peakrate, you can use the tokens in
the bucket to send packets at wire speed. To prevent this, you can specify a
peakrate so you can limit the speed that tokens in the bucket can be used.
