KVM over IP

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.
