Abstract
There is provided a method of resilient operation of a virtual network function (VNF) and a host platform configured to host VNF. The host platform comprises: first PMB configured to host first virtual platform (VP) with the help of first hypervisor, the first VP is configured, when the first hypervisor is in operational mode, to execute the VNF under primary VNF configuration; second PMB configured to host second VP with the help of second hypervisor with substantially less processing power than processing power of the first hypervisor, the second VP is configured, when the first hypervisor has failed, to execute the VNF under emergency VNF configuration. Second PMB is further configured to execute system controller operatively connected to first hypervisor, second hypervisor and I/O switch, the system controller configured to monitor status of first hypervisor and, responsive to a failure of first hypervisor, enable executing the VNF on second VP.
