What is WAN acceleration?
Short answer: WAN acceleration is the set of techniques that aim for a long-distance transfer to use contracted bandwidth despite latency, packet loss and TCP behaviour.
Definition
WAN acceleration answers an operational question: why a multi-gigabit link moves a dataset as if it were narrow. TCP waits for acknowledgements; the greater the distance and loss, the more idle time. Classic techniques (compression, deduplication, cache, error correction) attack part of the problem. Accelerating is not buying more bandwidth, and it is not storing the data.
Why it matters
Replication, cloud migration and applications across the WAN turn a network delay into a project. The business sees a transfer that will not finish; infrastructure sees a protocol that will not fill the pipe.
Without a design for latency and loss, the default answers are more bandwidth or more time. Often the bottleneck remains the protocol.
What it is not
It is not object storage or backup. Moving is not keeping or recovering.
It is not a time calculator. A speed multiple in a brochure does not prove the result on a specific link. This site does not publish that tool.
In the Azuba model
Data and AI infrastructure treats WAN acceleration and large-dataset transfer alongside storage: distinct capabilities in the same solution.
In Data and AI infrastructure, Bridgeworks covers data acceleration and movement. It does not replace storage or backup; it complements the portfolio.

Is more bandwidth WAN acceleration?
No. More bandwidth helps if the limit was capacity. If the limit is latency and loss, the link stays under-used. Acceleration attacks that behaviour, not only the carrier contract.
Does this site estimate how long my transfer will take?
No. V1 explains the problem. It does not calculate times or recommend a product from a number.
