Exponential backoff is an algorithm that uses feedback to multiplicatively decrease the rate of some process, in order to gradually find an acceptable rate. These algorithms find usage in a wide range of systems and processes, with radio networks and computer networks being particularly notable. See more An exponential backoff algorithm is a form of closed-loop control system that reduces the rate of a controlled process in response to adverse events. For example, if a smartphone app fails to connect to its server, it might try … See more The 'truncated' variant of the algorithm introduces a limit on c. This simply means that after a certain number of increases, the exponentiation stops. Without a limit on c, the delay … See more • Control theory See more Exponential backoff is commonly utilised as part of rate limiting mechanisms in computer systems such as web services, to help enforce fair … See more Exponential backoff algorithms can be used to avoid network collisions.

WebAbstract: Backoff techniques, of which the well-known exponential backoff is a special case, are based on adaptation of average retransmission delay as a function of the number of collisions experienced by each message accessing the contention channel. An analytical model for slotted-ALOHA channels using general backoff functions has been … WebHowever, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.
