Problems solved by technology

However, this method needs to send a large number of heartbeat messages, wasting network resources, and requires complex heartbeat configuration. The more network elements, the more complex, and the inconsistent detection time and results of different protocols may cause inconsistent disaster recovery and bypass actions, affecting the effect.
NFVO (Network Functions Virtualization Orchestrator, network function virtualization orchestrator) of virtualized network can statically manage VNF (Virtualized Network Function, virtualized network function) topology, but lacks dynamic management means

Embodiment Construction

[0034] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0035] figure 1 A flow chart showing a VNF state detection notification method according to an embodiment of the present invention. Such as figure 1 As shown, the method mainly includes:

[0036] Step 100, the virtualized network function module manager VNFM conducts unified state detection on virtual network function VNF network elements, and judges whether the state of the VNF changes, wherein the state of the VNF includes a fault state and a fault recovery state.

[0037] Specifically, a module with status monitoring and notification functions is set in the VNFM to detect the status of the VNF. If a VNF is in a fault state, it can be considered that the VNF is in an out of service state at this time, and if a VNF is in a fault recovery state, it can be considered that the VNF is in a service ...

Abstract

The invention discloses a VNF state detecting notification method, a VNF state detecting notification device and a VNF state detecting notification system, wherein the method, the device and the system relate to the field of network function virtualization, wherein the method comprises the steps of performing unified state detection on a VNF network element by a VNFM, determining whether the state of the VNF changes, wherein the VNF states comprise a fault state and a fault recovery state; if the state of a certain VNF changes, determining the current state of the VNF; and reporting the current state of the VNF to an NFVO so that the NFVO updates network topology according to the current state of the VNF and furthermore notifies the updated network topology to other VNFs and VNFMs. According to the method, the device and the system provided by the invention, unified detection is performed on the VNF state, thereby realizing simple operation, reducing a large amount of heartbeat information between the VNFs, saving network resource, realizing consistent disaster recovery and bypass operations of the VNF, and realizing dynamic representation of VNF network topology and automatic recovery operation of the NFVO.

Description

technical field [0001] The invention relates to the field of network function virtualization, in particular to a VNF state detection notification method, device and system. Background technique [0002] State detection between network elements is the basic means of network element disaster recovery and bypass technology. The current detection method is mainly to use service protocols between network elements to carry out meshed bidirectional detection. However, this method needs to send a large number of heartbeat messages, wasting network resources, and requires complex heartbeat configuration. The more network elements, the more complex, and the inconsistent detection time and results of different protocols may cause inconsistent disaster recovery and bypass actions, affecting the effect. The NFVO (Network Functions Virtualization Orchestrator, Network Function Virtualization Orchestrator) of the virtualized network can statically manage the VNF (Virtualized Network Funct...
