D. Bandwidth Consumption
The preconfigured network speed selection simply results in a different
Compression and Color Depth configuration in order to match the different
bandwidth limitations of the network type (UMTS, ISDN, etc.)
The following suggested network bandwidth planning table for IP-KVM installation
is from the test results with 3D-Labyrinth screen saver at Resolution 800x600, the
worst case consuming the highest network bandwidth.
