Patent ID: 11175955

Abstract:
Provided is a network function virtualization system. The system includes a single-domain virtualized network function manager (VNFM), a single-domain virtualized network function (VNF) entity, and a virtualized infrastructure manager (VIM); one or more network function virtualized single-domain orchestrators (NFV-DO), which are in one-to-one correspondence with single-domains. The NFV-DO includes a virtualized network function orchestrator (VNFO), which is configured to manage one or more of the following functions in the single-domain where the VNFO is located: a network service instance, a network service life cycle, VNFM instantiation, VNF instantiation and a VNF life cycle. The above solution can meet requirements for phased evolution implemented by a current NFV system and requirements for cross-border, cross-regional, multi-vendor service provision and multi-layer management.
