WebThe fixed window algorithm is a method used by rate limiting tools to track and throttle requests by dividing time into fixed intervals, or windows. Requests are counted within each window and if the number of requests exceeds a predetermined limit, subsequent requests are throttled until the next window. WebRatelimiting algorithms. We provide different algorithms to use out of the box. Each has pros and cons. Fixed Window. This algorithm divides time into fixed durations/windows. For example each window is 10 seconds long. When a new request comes in, the current time is used to determine the window and a counter is increased.
