Internal Rate Limiting

Definition of Internal Rate Limiting:

Internal rate limiting is a technique used in software systems to control the rate at which requests are processed. It involves setting a limit on the number of requests that can be processed within a specified time interval. This helps to prevent the system from being overloaded and ensures that all requests are processed in a fair and timely manner.

How Internal Rate Limiting Works:

  1. Request Arrival: When a request arrives at the system, it is checked against the rate limit.
  2. Limit Check: If the request is within the rate limit, it is processed immediately.
  3. Rate Limit Exceeded: If the request exceeds the rate limit, it is either queued or dropped, depending on the system’s configuration.
  4. Queue Management: If a queue is used, requests are processed in a first-in, first-out (FIFO) manner.
  5. Rate Limit Reset: The rate limit is typically reset at regular intervals, allowing the system to process new requests.
