The time difference between expected signal arrival and actual signal arrival times is called latency. It happens because of processing delays that happen inside network equipment. It is important to know magnitude and consistency of the latency. Modern applications require low latency for higher performance due to higher communication to computation ratio than in older applications. Low latency is essential to financial applications; high latency would create delay which might result in revenue loss. Evolving network traffic gets more latency-sensitive with introduction of cloud services. Design of the network, number of equipment and nodes between two servers, all that affects consistency of latency.
