What are the variations of the exponential backoff algorithm?

What are the variations of the exponential backoff algorithm?

The exponential backoff algorithm is a strategy for handling retries in network communications. Variations include linear backoff, full jitter, and decorrelated jitter.

Can you explain how full jitter works?

Full jitter adds randomness to the backoff time, which helps to prevent thundering herd problems by spreading out retries.

What are the advantages of using decorrelated jitter?

Decorrelated jitter reduces the chance of repeated collisions by adjusting the backoff time based on previous attempts, making it more adaptive.

Are there any scenarios where exponential backoff is not recommended?

Yes, in real-time systems where low latency is critical, exponential backoff may introduce unacceptable delays.
