 According to Cisco's product literature, IOS XR shares very little infrastructure with the other IOS trains, and is instead built upon a "preemptive, memory protected, multitasking, microkernel-based operating system". The microkernel was formerly provided by QNX; versions 6.0 onwards use the Wind River Linux distribution.
