- Similar to the token bucket algorithm, except that the requests are processed at a fixed rate.
- Implemented with a first-in-first-out (FIFO) queue
How it works?
Pros and Cons
Pros
- Memory efficient due to the limited queue size
- Suitable for cases where stable processing rate is desired
Cons
- Not suitable for a burst of traffic
- Difficult to tune the two parameters: Bucket size, Outflow rate
