Question
Routers are equipped with a dual leaky and token bucket. In one sentences explain:
(a) The role of the leaky bucket (ATM).
(b) The role of the token bucket (IP).
(c) Is it important which one is implemented first? and why?
(d) Consider the following burst arrival times to a leaky bucket followed by a token bucket with the following parameters: Leaky bucket departure rate: 1 packet per second. Leaky bucket size: 3, initially empty. Token bucket size: 5, initially full. Token arrival rate: 1 every 2 seconds. Determine the content of the buckets and packet drops for the following time interval. Note: operations are performed at the end of each cycle.

role of leaky bucket
It can be used to check that data transmissions, in the form of packets,[note 1] conform to defined limits on bandwidth and burstiness
