Question
Answer
How is bandwidth used in
KVM-over-IP systems?
Dominion KX II offers next-generation
KVM-over-IP technology the very best video
compression available. Raritan has received
numerous technical awards, confirming its high
video quality transmissions and the low
bandwidth utilization.
The Dominion KX II digitizes compresses and
encrypts the keyboard, video and mouse
signals from the target server and transmits IP
packets over the IP network to the remote
client to create the remote session to the user.
The KX II provides an at-the-rack experience
based on its industry-leading video processing
algorithms.
Screen changes, i.e., video accounts for the
majority of the bandwidth used and keyboard
and mouse activity are significantly less.
It is important to note that bandwidth is only
used when the user is active. The amount of
bandwidth used is based on the amount of
change to the server’s video display screen.
If there are no changes to the video the user
is not interacting with the server there is
generally no bandwidth used. If the user moves
the mouse or types a character, then there is a
small amount of bandwidth used. If the display
is running a complex screen saver or playing a
video, then there can be a larger amount of
bandwidth used.
How does bandwidth affect
KVM-over-IP performance?
In general, there is a trade-off between
bandwidth and performance. The more
bandwidth available, the better performance
can be. In limited bandwidth environments,
performance can degrade. The Dominion KX II
has been optimized to provide strong
performance in a wide variety of environments.
