KVM (Keyboard, Video, Mouse) over IP

What it is

KVM over IP extracts the keyboard, video, and mouse signals of a target machine and ships them across an IP network to an operator console. The operator interacts with the remote machine as if it were sitting under the desk; the actual hardware lives in a secured server room.

How it works

Two modes are common:

• Hardware KVM — a transmitter appliance attached to the target's HDMI/DP + USB ports digitises and packetises the signals for an IP fabric (often 1 GbE or 10 GbE).
• Software KVM — agents on the targets stream the framebuffer over RDP, VNC, or proprietary protocols. Cheaper, more flexible, slightly higher latency.

Why it matters in control rooms

In a NOC or situation centre, operators switch among dozens of target machines per shift. KVM-over-IP lets a single console reach every target without physical cable runs, scales horizontally (add operators, not workstations), and keeps the actual servers in a hardened room. Combined with a video wall, the same target can be projected and manipulated by several people at once.
