Token Bucket Model The rate limiting technique that the Dashboard API implements is based on the token bucket model. The token bucket is an algorithm used to check that the data that is transmitted in a certain amount of time complies to set limits for bandwidth and burstiness. Based on this model, if the number of API requests crosses the set threshold for a certain amount of time, you will have to wait a set amount of time until you can make another request to the API. The time you must wait depends on how many more requests you performed above the allowed limit, with the more requests you have performed, the more time you would have to wait.

What is the technique used in Cisco Meraki Dashboard API to limit the rate of API calls? Sliding Window Model Token Bucket Model Fixed Window Model Token Cluster Model
