Main difference Token Bucket allows traffic burst by nature. If tokens are not … 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. bishop lyles cogic
