SDN/NFV Technology

Through software and hardware decoupling, Network Functions Virtualization (NFV) proposes using IT virtualization related technologies, to virtualize entire classes of network node functions into building blocks that may be connected, or chained, together to create communication services. NFV focuses on optimizing the network services and decouples the network functions, SDN separates the network’s control and forwarding planes and provides a centralized view of the distributed network for more efficient orchestration and automation of network services.

SDN/NFV Technology Application

Through the SDN/NFV technology ,to implement network cloud in a unified physical infrastructure. Function reconstruction: constructing an“agile and open”service function layer. Operation reconstruction: creating a“smart operation”orchestration and management layer. ZTE's ElasticNet, a 5G-oriented open network architecture based on the SDN/NFV technology, enables operators to achieve the above reconstructions, provides them with end-to-end telecom cloud solutions, and assists them in network transformation.

SDN/NFV Solution of ElasticNet

ElasticNet is ZTE’s next-generation network solution. It uses software-defined networking (SDN) and network function virtualization (NFV) technologies, both of which enable elastic network configuration. This helps an operator meet the changing demands of customers and quickly implement new business models. ElasticNet integrates SDN and NFV technology to create a flat network that suits diverse functions and demands. With cloud computing technology, ElasticNet provides functions and systems for network control. It decouples the control and forwarding functions so that network control is centralized, and it makes the network comply with open, standard protocols.

SDN/NFV Technology for Network Reconstruction

The SDN/NFV technology has been used for operator`s network reconstruction. To achieve digital transformation, operators need to reconstruct networks by adopting SDN/NFV technologies, focusing on data center, and building an open, agile and intelligent cloud network. Network reconstruction with SDN/NFV technology is generally divided into three phases: Infrastructure reconstruction: building a“cloud-network convergence”infrastructure layer. Function reconstruction: constructing an“agile and open”service function layer. Operation reconstruction: creating a“smart operation”orchestration and management layer. ZTE's ElasticNet, a 5G-oriented open network architecture based on the SDN/NFV technology, enables operators to achieve the above reconstructions, provides them with end-to-end telecom cloud solutions, and assists them in network transformation.
