KVM in Air Traffic Control Centres ► Preventive monitoring, Redundancy and Fallback
Customer benefits using KVM - Full safety thanks to redundancy and fallback
// 5
Coordinating departures and arrivals and controlling overflying
traffic requires the maximum reliability of all IT components.
Air Traffic Control Centres are sensitive security areas that can
enjoy major benefits through deploying a KVM extender such
as DL-Vision. This allows computers to be removed from the
control centre, improving working conditions and enabling pre-
ventative monitoring and event reporting.
Regulatory safety demands can be met by integrating the Dev-
Con-Center. This provides centralized proactive monitoring and
configuration of network-capable G&D devices. Depending on
results or predefined thresholds, the DevCon-Center triggers
and sends a message to the system administrator, allowing
them to react before any failures occur.
Redundant and fallback systems are essential for
the controller´s work. To prevent a total breakdown,
three independent systems (primary, redundant, and
fallback) are applied to the controller’s desk. Each sys-
tem consists of a computer and a KVM extender line.
By pressing a button at a KVM switch installed next to
the desk, switching between systems is made easy.
The unlikely event of a system breakdown despite preven-
tive monitoring requires a concept that allows controllers
to continue their work safely and intuitively in their fami-
liar environment.
This requires a redundant system that is safeguarded by
another fallback system. Now two functional lines are still
available even if the primary connection fails.
Three independent but identical systems per controller
desk serve for a primary, a redundant and a fallback sys-
tem. Each of these three systems consists of a computer
and a KVM extender line. The controller only needs to
switch between the three systems by simply pressing a
button on the KVM switch, e.g. DL-MUX4.
Screen freeze function “freezes” the image last displayed
on the monitor. Users are provided with the information
last received before switching to a redundant system.
