●Separate of virtual resource management and service management causes two views of OSS and NFVO, and it is inconvenient for corporation management;
●Virtual management operations are lack of the unified portal and need to switch in several systems (NFVO/VNFM/VIM), so in practice it’s quite difficult to use;
●As separate of EMS and VNFM, repetition of some generic functions might go against the unified management of network elements.
ZTE NFVO+ solution is the expansion and enhancement of NFVO. It implements vertical integration of NFVO/VNFM/VIM and unified portal; horizontal integration of VNFM/EMS; unified management of virtual and physical network; integration with traditional OSS; E2E network cooperation and unified management provided for carriers, and improving O&M efficiency.
●Unified views: vertical integration of NFVO/VNFM/VIM, unified portal, simplified O&M.
●Unified management of virtual network and physical network: horizontal integration of VNFM/EMS/vEMS, unified management of PNF/VNF.
●Integration of O&M: integration of NFVO and OSS, correlation analysis of services, virtual resource and physical resource, E2E management of network.
