First decoupling and interconnection test of ZTE’s ZENIC SDN controller

ZTE has announced that it has completed the industry’s first decoupling and interconnection test of ZTE’s ZENIC SDN controller with the carrier-grade CloudOS of China Mobile.

ZTE helps China Mobile introduce SDN to NFV deployment so as to accelerate the core network 3-layer decoupling and NFV process and promote the NFV and SDN interface standardization, thereby building up a new and more flexible infrastructure for the future-oriented 5G network of China Mobile.

The joint test involves environment installation inspection, basic function and stability test, and verifications of over 20 particular protocol extensions in NFV scenario. It successfully implements automatic launching and dynamic adjustment of NFV sites.

During the entire life cycle of the NFV network elements, SDN technologies can continuously enhance network resource utilization efficiency, improve network virtualization, simplify the compatibility with the existing network, and increase the network agility in various service automation scenarios. During the test, Openflow is used as the standard protocol for SDN control, forwarding and separation, and OVSDB is used as the standard protocol for vSwitch management, meeting requirements of decoupling and interconnection and vigorously promoting the NFV and SDN interface standardization.

Compatible with mainstream virtualized software, ZTE’s ZENIC SDN vDC controller is applicable to the scenarios of hybrid overlay, hardware overlay and software overlay. It has also been employed to complete the interconnection with the third-party OpenStack cloud platforms such as RedHat in addition to China Mobile’s CloudOS case. By virtue of unified resource planning and deployment, it can quickly construct new virtualized data centers.

China Mobile has initiated virtualization tests and pilots by gradually integrating SDN technologies to implement automated network configuration, enhance network service capability and horizontal scalability. Its newly-built core network and network elements delivering value-added services will adopt virtualized network elements in NFV architecture to substitute the traditional ones, intending to realize hardware resource sharing and further extend the scope of sharing in the resource pool by decoupling software from hardware, thereby accelerating the network virtualization transformation.

As China’s first platinum member of OpenDaylight, ZTE has already deployed 360 SDN/NFV commercial and POC projects with world-leading operators. It has built a large number of virtualized data center projects for international and domestic operators and enterprises, including China Mobile’s Hohhot private cloud, China Telecom Shanghai’s LSN, China Telecom Guangxi’s CO re-architecting, etc.

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
