WebLeaky bucket (closely related to token bucket) ... In a fixed window algorithm, a window size of n seconds (typically using human-friendly values, such as 60 or 3600 seconds) is used to track the rate. Each incoming request increments the counter for the window. If the counter exceeds a threshold, the request is discarded. WebA Token Bucket is fairly simple to implement. Start with a bucket with 5 tokens. Every 5/8 seconds: If the bucket has less than 5 tokens, add one. Each time you want to send a message: If the bucket has ≥1 token, take one token out and send the message. Otherwise, wait/drop the message/whatever.

Rate Limiting Part 1 - Hechao

The token bucket is an algorithm used in packet-switched and telecommunications networks. It can be used to check that data transmissions, in the form of packets, conform to defined limits on bandwidth and burstiness (a measure of the unevenness or variations in the traffic flow). It can also be used as a scheduling algorithm to determine the timing of transmissions that will comply with the limits set for the bandwidth and burstiness: see network scheduler.
