US 2021/0342178 A1 · METHOD AND DEVICE FOR INSTANTIATING VIRTUALIZED NETWORK FUNCTION

Abstract

A method includes: a first network element receives first information used to indicate to instantiate a VNF. The first network element obtains hardware resource information used to indicate an available resource of a network functions virtualization infrastructure, where the available resource includes a resource of at least one piece of hardware, and the hardware represents a minimum physical resource set used to bear a virtual machine. The first network element determines, based on the first information and the hardware resource information, a one-to-one mapping relationship between at least one virtual machine corresponding to the VNF and at least one piece of hardware corresponding to the VNF. The first network element determines, based on the mapping relationship, to instantiate the at least one virtual machine on the at least one piece of hardware.

Dependent claims

A method for instantiating a virtualized network function (VNF), comprising:

receiving, by a first network element, first information used to indicate to instantiate a VNF;
obtaining, by the first network element, hardware resource information used to indicate an available resource of a network functions virtualization infrastructure, wherein the available resource comprises a resource of at least one piece of hardware, and the hardware represents a minimum physical resource set used to bear a virtual machine;
determining, by the first network element based on the first information and the hardware resource information, a one-to-one mapping relationship between at least one virtual machine corresponding to the VNF and at least one piece of hardware corresponding to the VNF;
and
determining, by the first network element based on the mapping relationship, to instantiate the at least one virtual machine on the at least one piece of hardware.

A network element device for instantiating a virtualized network function (VNF), the network element device comprising:

a communications unit configured to receive first information used to indicate to instantiate a VNF, wherein
the communications unit is further configured to obtain hardware resource information used to indicate an available resource of a network functions virtualization infrastructure, wherein the available resource comprises a resource of at least one piece of hardware, and the hardware represents a minimum physical resource set used to bear a virtual machine;
a resource orchestration unit configured to determine, based on the first information and the hardware resource information, a one-to-one mapping relationship between at least one virtual machine corresponding to the VNF and at least one piece of hardware corresponding to the VNF;
and
a deployment unit configured to determine, based on the mapping relationship, to instantiate the at least one virtual machine on the at least one piece of hardware.
