Based on the world's first ONOS (Open Network Operating System) open architecture SDN IPRAN green business enterprises in Tianjin Unicom successful opening, which is an important outcome of China Unicom, Huawei and ONOS SDN open source community in the field of joint innovation.

According to a "software-defined networking market in North America, including solutions (SDN switches, SDN controllers, virtual cloud application), end-users (businesses, telecom service providers, cloud service providers)," the survey report, as of 2019, North American software-defined network (SDN) market will grow from $ 1,478,300,000 in 2014 increased to $ 4,604,400,000, compound annual growth rate (CAGR) to reach 25.5 percent.

All-optical switching is the future direction of development, but also from the current development trend, this "future" is not far away. Many in the industry view: ROADM-based networking and scheduling is not sensitive to the rate applicable to ultra-high-speed optical networking and scheduling transmission systems, but also can greatly reduce power consumption and floor room. After years of gradual improvement technology, functionality and performance, CDC-F ROADM (ie colorless and directionless without conflict and supports flexible grid capacity reconfigurable optical forked Multiplexer) device has matured, basically solved the light layer networking encountered many problems. Some foreign operators in the deployment of 100G networks have begun to do large particles using ROADM traffic scheduling, a direct transition to an all-optical network. March 2015, Verizon announced the adoption of Ciena and Cisco's packet optical transport platform Metro 100G deployment, CDC-F ROADM technology for the first time to get a commercial scale. In the same month, Alcatel-Lucent announced that Verizon will use its latest CDC-F ROADM technology to upgrade Verizon's long-haul optical transport network.

Recently, ZTE was awarded the SDN OpenFlow 1.3 ONF conformance testing certification, becoming the first manufacturer to receive this certification. ZTE Bearer Network Products M6000-S in the test performance, stability, and other vendors controllers successfully docking site, excellent test results.

For carriers, SDN, NFV and Cloud has become the ICT transformation keywords. And in order to "separate data and control, software and hardware decoupling" is characterized by SDN already determined the status to the next generation network architecture evolution direction. China Telecom Group, Wei Leping CST has pointed out, SDN open network IT process, is an important breakthrough in the direction to telecommunications technology, as well as IT and software business breakthroughs channel telecommunication barriers, suggesting a large adjustment of industrial structure pattern.

Open Networking Foundation (ONF) Executive Chairman Dan Pitt in September 8, 2015 ONF Member Workday officially announced, Huawei, ZTE, H3C, Digital Network (DCN) and other four companies formally through five SDN switch by the BII - OpenFlow v1.3 conformance certification testing center for testing and certification of global SDN, becoming the world's first through OpenFlow v1.3 protocol conformance certified equipment.

Software-defined networking (Software Defined Network, SDN), is a new kind of network innovation Emulex network architecture, network virtualization is an implementation of its core technology OpenFlow network devices through the control and data planes separated, in order to achieve the flexible control of network traffic, the network as a conduit to become more intelligent.
