Well, before answering I went to sources and I don't feel that
confident, but here:
The way token bucket alg. is tought is by making a paralel with a
leaky bucket, where you have a bucket of size bc+be, and every Tc
you leak Bc (if any) out of the bucket. Every time you tx, you add to
the bucket, capacity permiting (or else, you block).
In this algorithm, Be is not Tc related (and some configurations
just work like this, i.e. you can have Be larger than AR/Tc (access rate)
Some books, though, represent Bc+Be as a line in the same domain as Bc,
conceptually assigning Bc+Be the idea of PIR (Peak Information rate).
I guess that the difference is best understood in reading RFC2697
and RFC2698 (single rate and two rate three color markers).
Sorry if I added confusion...
