Management method, device and system for virtualized network function network element

Abstract

Embodiments of the present invention provide a management method, device and system for a virtualized network function network element, wherein the method includes: the VNF resource pool management device receives a VNF network element request message sent by a VNF resource pool user device, and the VNF network The element request message includes the attribute information and location policy of the VNF network element to be requested; the VNF resource pool management device selects the VNF resource pool from the VNF resource pool according to the VNF network element request message and the location information of the VNF network element in the VNF resource pool Determine the first VNF ​​network element conforming to the attribute information and location policy, the first VNF ​​network element includes at least one VNF network element; the VNF resource pool management device sends the VNF network element to the VNF resource pool user device A response message, where the VNF network element response message includes identification information of the first VNF ​​network element. Therefore, the risk that the function group formed by the VNF network elements cannot work normally can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a management method, device and system for virtualized network function network elements. Background technique [0002] At present, major operators pay more and more attention to virtualized network functions (Virtual Network Function, VNF for short). VNF includes virtualization of L3 functions and virtualization of L4-L7 functions, wherein virtualization of L3 functions may include: virtual provider edge equipment (virtual Provider Edge, vPE for short), virtual broadband network gateway (virtualBroadband Network Gateway, vBNG for short) and virtual Date Center Gateway (vDC GW for short), etc. The virtualization of L4-L7 functions can include: virtual load balancer (virtual Load Balance, vLB for short), virtual WAN optimization controller virtual Wan optimizationController, referred to as: vWoC) and virtual firewall device (virtual Fire Wall, ...

AI Technical Summary

Problems solved by technology

[0004] However, if at least two VNF network elements constituting a functional group run on the same VM or the same Hypervisor or the same server, when the VM or the Hypervisor or the server fails (also known as the risk sharing problem), it will Make the functional group composed of these VNFs not work normally
