Problems solved by technology

However, during the deployment of virtual network function network elements, it was found that the implementation details of various vendors were quite different, and the ideal elastic scaling effect could not be achieved.
In particular, the expansion and contraction of virtual machines involving network address allocation is generally inseparable from the intervention of manual configuration and cannot be implemented automatically

Abstract

The invention discloses a network address allocation method and system for a virtual network function and a VNFM, and relates to the field of data communication. The method comprises the steps that aVNFM sends a network address pool application request to a DHCP server; The VNFM receives a network address pool distributed by the DHCP server; And the VNFM allocates network addresses to the networkcards of the active virtual machine according to the number of the network addresses in the network address pool and the number of the network cards of the active virtual machine. According to the method and the device, a plurality of network addresses are applied for the network cards of the virtual machines in the virtual network function in advance, and then the network addresses are equally distributed to the network cards according to the load balancing principle, so that the flexibility of network address distribution can be improved.

Description

technical field [0001] The present disclosure relates to the field of data communication, and in particular to a network address allocation method and system for a virtual network function, and a VNFM (Virtualized Network Function Manager, virtual network function manager). Background technique [0002] During the promotion and implementation of network reconfiguration, NFV technology has been gradually introduced into the live network. However, during the deployment process of virtual network function network elements, it was found that the implementation details of various manufacturers were quite different, and the ideal elastic scaling effect could not be achieved. In particular, the expansion and contraction of virtual machines involving network address allocation is generally inseparable from the intervention of manual configuration and cannot be implemented automatically. Contents of the invention [0003] A technical problem to be solved in the present disclosure ...
