System, method, and computer program for managing fault recovery in network function virtualization (NFV) based networks

A non-transitory computer readable medium storing computer code executable by a computer processor to perform a method, the method comprising:

• identifying a first network component of a network function virtualization (NFV) based network, the first network component being a first hardware unit having one or more computer processors for executing a plurality of virtual network functions (VNFs);
• selecting a plurality of second network components to be used for replacing the first network component in the NFV based network, based on a respective load of the plurality of second network components, the plurality of second network components each being a second hardware unit having one or more computer processors for executing one or more VNFs installed thereon;
• installing duplicate instances of the plurality of VNFs across the plurality of second network components, including at least installing a duplicate instance of a first VNF of the plurality of VNFs on one second network component of the plurality of second network components, installing a duplicate instance of a second VNF of the plurality of VNFs on another second network component of the plurality of second network components, and creating at least two duplicate instances from a third VNF of the plurality of VNFs by splitting the third VNF into the at least two duplicate instances and distributing the least two duplicate instances across two or more second network components of the plurality of second network components.

A system comprising:

• a memory system;
• and
• one or more processing cores coupled to the memory system and that are each configured for:
• identifying a first network component of a network function virtualization (NFV) based network, the first network component being a first hardware unit having one or more computer processors for executing a plurality of virtual network functions (VNFs);
• selecting a plurality of second network components to be used for replacing the first network component in the NFV based network, based on a respective load of the plurality of second network components, the plurality of second network components each being a second hardware unit having one or more computer processors for executing one or more VNFs installed thereon;
• installing duplicate instances of the plurality of VNFs across the plurality of second network components, including at least installing a duplicate instance of a first VNF of the plurality of VNFs on one second network component of the plurality of second network components, installing a duplicate instance of a second VNF of the plurality of VNFs on another second network component of the plurality of second network components, and creating at least two duplicate instances from a third VNF of the plurality of VNFs by splitting the third VNF into the at least two duplicate instances and distributing the least two duplicate instances across two or more second network components of the plurality of second network components.
