Patent ID: 10326653

Abstract:
A method for upgrading a network functions virtualization application includes creating, by a virtualized infrastructure manager (VIM), a network resource according to an upgrade plan for the network functions virtualization application; creating, by the VIM, a virtual machine for a new-version virtualized network function (VNF) according to the upgrade plan; configuring, by the VIM, the virtual machine on a test network according to the network resource; performing, by the VIM, upgrade configuration on the virtual machine according to an upgrade configuration script to obtain the new-version VNF; and switching, by an NFV orchestrator, an earlier-version VNF to the new-version VNF after determining that a function test of the new-version VNF on the test network is successful. In the embodiments of the present disclosure, an automated upgrade procedure and upgrade steps for a network functions virtualization application are defined, so that upgrading the network functions virtualization application can be automated.
