NEC, Friday announced the completion of the deployment of Network Functions Virtualization (NFV) solutions, including virtualized Evolved Packet Core (vEPC) and a Virtual Network Function Manager (VNF Manager) for NTT DOCOMO's commercial networks. This week, DOCOMO started providing its commercial mobile communication service by using the NFV technologies.
According to NEC, the vEPC virtualizes the functions of a LTE core network, including the Mobility Management Entity (MME), the Serving Gateway (S-GW), and the Packet Data Network-Gateway (P-GW). A VNF Manager from Netcracker, a wholly owned NEC subsidiary, handles lifecycle events, such as creation, activation, termination and updates of Virtualized Network Functions (VNF). The NFV solutions delivered by NEC open the way both for flexibly increasing or decreasing the processing capacity of the core network according to the load and for automatically recovering from hardware failure in a short time. This will help improve the stability and reliability of the core network, said NEC.
