Abstract
An example operation may include a system, comprising one or more of: receiving a status failure notification for a VNFCI, retrieving a peer VNFCI admin state and a peer VNFCI operational state, taking no action when one or more of: the peer VNFCI admin state is not online, the peer VNFCI is not reachable, and the peer VNFCI operational state is active, retrieving current issues reported on resources associated with the peer VNFCI when one or more of: the peer VNFCI admin state is online, the peer VNFCI is reachable, and the peer VNFCI operational state is not active, sending a state change request message with an active state to the peer VNFCI when the current issues do not exist, and starting a retry timer for the peer VNFCI.
Claims20
A system, configured to:
- receive, by a virtual network function manager (VNFM), a status failure notification for a virtual network function component instance (VNFCI);
- retrieve, by the VNFM, an administrative (admin) state of a peer VNFCI and an operational state of the peer VNFCI;
- take no action, by the VNFM, when one of a following condition is identified:
- the admin state of the peer VNFCI indicates that the peer VNFCI is not online,
- the peer VNFCI is not reachable by the VNFM, or
- the operational state of the peer VNFCI indicates that the peer VNFCI is active;
- send, by the VNFM, a state change request message, indicating a next state as active, to the peer VNFCI when current issues related to resources associated with the peer VNFCI do not indicate a critical issue;
- and
- start, by the VNFM, a retry timer for the peer VNFCI based on the state change message being sent.
A method, comprising:
- receiving, by a virtual network function manager (VNFM), a status failure notification for a VNFCI;
- retrieving, by the VNFM, an administrative (admin) state of a peer VNFCI and an operational state of the peer VNFCI;
- taking, by the VNFM, no action when one of a following condition is identified:
- the admin state of the peer VNFCI indicates that the peer VNFCI is not online,
- the peer VNFCI is not reachable by the VNFM, or
- the operational state of the peer VNFCI indicates that the peer VNFCI is active;
- sending, by the VNFM, a state change request message, indicating a next state as active, to the peer VNFCI when current issues related to resources associated with the peer VNFCI do not indicate a critical issue;
- and
- starting, by the VNFM, a retry timer for the peer VNFCI based on the state change message being sent.
A non-transitory computer readable medium comprising instructions that when executed by a processor of a first virtualization network function manager (VNFM) cause the processor to perform:
- receiving a status failure notification for a VNFCI;
- retrieving an administrative (admin) state of a peer VNFCI and an operational state of the peer VNFCI;
- taking no action when one of a following condition is identified:
- the admin state of the peer VNFCI indicates that the peer VNFCI is not online,
- the peer VNFCI is not reachable by the VNFM, or
- the operational state of the peer VNFCI indicates that the peer VNFCI is active;
- sending a state change request message, indicating a next state as active, to the peer VNFCI when current issues related to resources associated with the peer VNFCI do not indicate a critical issue;
- and
- starting a retry timer for the peer VNFCI based on the state change message being sent.
