Abstract

An example operation may include a system, comprising one or more of receiving a virtual network function component instance (VNFCI) status notification resumption message with an active state when a peer VNFCI operational state is active, retrieving a timestamp of a VNFCI state change to an active state from an element VNFCI state database, retrieving a timestamp of a peer VNFCI state change to active from an element VNFCI state database, sending one or more of: a request to a virtual network function manager (VNFM) to determine if the VNFCI network is isolating while an operating state was active, and a request to the VNFM to determine if the peer VNFCI network is isolating while an operating state was active, sending a state change request with standby state to the peer VNFCI when the VNFCI is not network isolated and the peer VNFCI is network isolated, and a VNFM response is received regarding the VNFCI, a timeout response from the VNFM, and a VNFM response is received regarding the peer VNFCI, and sending a state change request with standby to the VNFCI with one or more of: the VNFCI network isolate and peer VNFCI is not network isolated, and the VNFCI is network isolated or the peer VNFCI is not network isolated, and the VNFCI is not network isolated and the peer VNFCI is network isolated and the VNFCI is in preferred standby.
