E. 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.
