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. WebFixed Window Rate Limiter. This is the simplest technique and it's based on setting a limit for a given interval of time (e.g. 5,000 requests per hour or 3 login attempts every 15 …

Token Bucket vs Bursty Rate Limiter - DEV Community

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.
