Updated:2015/12/15 16:31

China Future Network Development and Innovation Forum 2015 was held in Nanjing recently, Zhang Yunyong, vice president of China Unicom Network Research Institute, revealed China Unicom’s planning ideas in SDN/NFV field. He said that China Unicom will launch SDN/NFV pilot verifications in 2016 and expand from the edge networks to core networks.

Zhang Yunyong said, operators have faced increasing downward pressures in recent years, including weak income growth, rapid growth of data traffic, unmatched hardware expansion speed with the traffic data growth rate and other problems, but they can improve the network capacity and save cost through the SDN. Therefore, China Unicom has started researches on SDN.

Judging from the industry view, the first is to set up the standards, China Unicom has actively cooperated with all the major standards organizations in setting the standards, the cloud computing standard Y.3512 (Y.CCNaaS) led by China Unicom has been formally approved by ITU-T and become the first international cloud computing-network service standard. The second is to start the tests, China Unicom has completed tests of 6 mainstream vendors and 7 solutions and formed test reports. The third is R&D, including platforms, business and other aspects. China Unicom’s platforms includes WoCloud and WoMusic; the WoCloud-based VPC service is developed on the VPC business of Amazon and the management system of business chain is developed independently.

In addition, China Unicom has also conducted in-depth analysis of DCI. Zhang Yunyong pointed out that Future Network will take data center as its core and the data center architecture will become more important. China Unicom has already conducted prototype verification of the data center through WAN SDN. China Unicom’s Future Network architecture will also take data center as the core, including large scale core DC and wide coverage edge DC, the data centers of different levels will bear different VNFs and realize virtualization of the network element.

He also revealed China Unicom’s SDN/NFV development schedule of the next 5 years, according to the plan, China Unicom will launch SDN/NFV pilot verifications in 2016, including realization of the SDN-based multi-user virtual network and business chain management system, optimization of the network forwarding path among different data centers, realization of the NFV supporting platforms such as IMS and others; complete the NFV prototype systems including IMS, EPC and others; China Unicom will also carry out SDN-based IPRAN separation of control and bearing, realize verifications and unified low-cost deployment of SDN/NFV-based vCPE gateway and vOLT/smart ONT.

2017-2018 will enter the product development and deployment stage, China Unicom will complete the upgrading of computer rooms and DC rooms in first-tier and key second tier cities and expand the scope of DCI interconnection planes; in addition, it will also achieve the customized define, combine and open of the services, as well as plan, expansion and addition of new services according to their needs.

During 2019-2020, China Unicom plans to realize output of SDN/NFV to the core network, transmission networks and access networks, promote the collaboration of DC with networks, synergetic arrangement of the business and intensive management and control of data.

To support this schedule, China Unicom Network Research Institute will collocate its personnel in a matrix way to carry out technology researches and experimental work, and the R&D group will reach more than 200 people. In addition, China Unicom will cooperate with external agencies to jointly promote implementation of relevant business.
