How does exponential backoff affect latency?

Can you explain how exponential backoff works in networking?

Exponential backoff is a strategy used to space out repeated attempts to communicate over a network, especially after failures. It increases the wait time exponentially after each failed attempt.

How does this affect latency in a network?

It can increase latency initially, as the wait times grow longer after each failure. However, it helps reduce congestion and can lead to faster recovery in the long run.

Are there scenarios where exponential backoff is not effective?

Yes, in highly dynamic environments or when the failure rate is very high, exponential backoff may lead to excessive delays.

What are some alternatives to exponential backoff?

Alternatives include linear backoff, where wait times increase by a constant amount, or adaptive backoff, which adjusts based on network conditions.
