Overview:
Downloading large files can congest your network. You can detect large data transfers with Kerio Control's bandwidth management.
Configuring Kerio Control
When configuring the bandwidth management rules, set the traffic type to Large data transfer.
Detecting large data transfers
Kerio Control tests:
- The volume of the transferred data
- The duration of the longest idle interval
If Kerio Control detects at least 1000 KB of data (200 KB for Kerio Control 8.6.2 and older) without interruption of at least 5 seconds, then the transfer is considered as a large data transfer.
See the following examples for details.
Examples of large data detection
After transferring the third data load, Kerio Control detects the transmission as a large data transfer.
The connection has transferred 1000 KB of data with the longest idle interval of three seconds.
Kerio Control does not detect the transmission as a large data transfer.
The connections have transferred 750 KB of data followed by a five-second interval.
After transferring the third data load, Kerio Control detects the transmission as a large data transfer.
The first data load is followed by a six-second idle interval > Kerio Control does not detect the transmission as a large data transfer and sets the data counter to zero.
When the second and third data load is transferred (1000 KB), the longest idle interval is three seconds > Kerio Control detects a large data transfer.
