The Token Bucket Algorithm
The algorithm can be conceptually understood as follows:
- A token is added to the bucket every seconds.
- The bucket can hold at the most b tokens. If a token arrives when the bucket is full, it is discarded.
- When a packet (network layer PDU) of n bytes arrives, n tokens are removed from the bucket, and the packet is sent to the network.
- If fewer than n tokens are available, no tokens are removed from the bucket, and the packet is considered to be non-conformant.

Famous quotes containing the words token and/or bucket:
“The token woman carries a bouquet of hothouse celery
and a stenographer’s pad; she will take
the minutes, perk the coffee, smile
like a plastic daisy and put out
the black cat of her sensuous anger
to howl on the fence all night.”
—Marge Piercy (b. 1936)
“Dear fellow-artist, why so free
With every sort of company,
With every Jack and Jill?
Choose your companions from the best;
Who draws a bucket with the rest
Soon topples down the hill.”
—William Butler Yeats (1865–1939)
