In What Conditions Is DES Recommended?

You can estimate the transmission time by using the following formula. If data transmission cannot be complete by the Internet within the time you expect, try DES. The data transmission time is calculated as follows:

Transmission time (days) = [Total capacity (KB)]/[Bandwidth (Mbit/s) x 125 x Network utilization rate x 60 (seconds) x 60 (minutes) x 24 (hours)]
