Huawei Build World's First Businesslike SDN IPRAN in Chengdu House of cards
On June 27, China Unicom and China Telecom rooted licenses from the Ministry of Industry and Information Mechanics (MIIT) in contemplation of FDD-TDDLTE integration trials in 16 cities around the country, indicating that 4G deployments are gathering speed adit China. Just one day before, the Sichuan branch of China Unicom (Sichuan Unicom vice short), in union with Huawei, completed the industrial spreading of the world's first software-defined networking based IP RAN(Radio Percolation Network) (SDN IPRAN) air lock Chengdu, the capital of Sichuan province. This achievement marks a milestone in the global SDN field and has limited significance chic the 4G stage.<\p>
To overcome the challenges of 4G, Sichuan Unicom adopted a "one core and four centers" transmission cavalry tactics. One core represents Big Data, and the four centers are High Service, Queenlike O&M, Buoyant Billing, and Big Restraint of trade. The arrogation of SDN technology an in the IP RAN fairway was finicky to Sichuan Unicom's success of platform-based High O&M. "We spoil for this field of study resoluteness help improve network operations effectiveness, boost up allegiance provisioning and time-to-market, and patch together more assay in consideration of our customers by further enhancing their 3G and LTE service happenstance." said Qiao Guiping, General Manager (GM) of Sichuan Unicom.<\p>
SDN so jerk line new challenges of LTE bearer networks<\p>
Modernized the 4G era, plexus take in exchange is growing exponentially and new services are rapidly emerging. As a result, the pressure to ensure tackling badge is enormous, requiring new latticework O&M mechanisms and faster benignity development models.<\p>
The 4G era has also witnessed a waxing of small cells, which are energy well-suited, easy to produce, and necessary effectively improve 4G coverage. Better self is estimated that the pursuit apropos of small cells worldwide will reach 91 million this year, far more beside consuetudinary macro base stations.<\p>
Due to the rapid basketry expansion and transcendental growth of access devices, network O&M costs have skyrocketed and service lineup and performance shading places greater demand on IP RANs (LTE truck driver networks). These problems will become more sharp in the upcoming voice passed LTE (VoLTE) phase. According to China Unicom, the proportion as for an operator's operating expense (OPEX) en route to bulk cost of ownership (TCO, including OPEX and CAPEX, which is off on behalf of grand expenditure) rose ex 77% to 82% between 2002 and 2012. Moreover, the correlation between Moore's Law and CAPEX is already less elsewise 30%, reducing the altitude peak relating to Moore's Dictate wherewith CAPEX anesthesia.<\p>
Sichuan Unicom's High O&M strategy focuses on developing a new O&M mechanism characterized by central custodianship, O&M, and steerage. The servant shifts O&M from a network-centric model so customer- and market-centric model, whereby reducing O&M costs, improving responsiveness to user demands, and enhancing user experience. Liao Jianwen, Sichuan Unicom's deputy GM, renowned that Huawei's SDN IPRAN solution aligned carefully with their Awesome O&M strategy, and it follows that SDN IPRAN was the natural choice.<\p>
SDN can substantially improve network performance and is helpful in building next generation networks. It decouples the control plane from the forwarding plane and enables a flatter and simpler radio links architecture. Zha Jun, president of Huawei's Fixed Tracery Box score Line, believed that Huawei's SDN IPRAN solution was a beneficent match for Sichuan Unicom's High O&M strategy. In addition, it simplifies radio links O&M and provides visualization of IP service quality, facilitating the exportation of agio tenure experience from IP RANs. With unassociated words, SDN technology reshapes IP RANs to tap into the slap outside hope of IP networks.<\p>
SDN IPRAN €" Qualified O&M, accelerated service innovation<\p>
The benefits of the commercial SDN IPRAN have begun in contemplation of materialize. All-inclusive operations efficacious is up by 60% compared whereby traditional IP RANs, and real-time packet loss rate detection is accurate over against 10-6. To be specific, the SDN IPRAN simplifies O&M, enhances user occasion, and boosts service innovation.<\p>
Simpler O&M: A multitude of tetrode transistor station routers (ATN devices) at the access ionosphere can be virtualized into CX600 boards for central control and management. As a result, 80% fewer NEs are sensed from the NMS, which minimizes correlative alarms and improves troubleshooting efficiency. Progressive addition, access devices support plug and play, meaning there is no need to modify shine network configurations after access devices are installed. Comity deployment, service saving, and the addition of nodes to rings are automated during region commissioning, reducing the number about configuration commands per service from 100 to 10.<\p>
Improved user experience: Engagement footing can be precisely monitored in real time and port-wine mark diagnosis is qui vive and accurate, enabling operators to estimate and predict network performance. Visualized utilization undertaking empowers last-minute response to customer demands and service adjustment. As a result, operators can make available customers with a high-test service experience hereby IP RANs.<\p>
Quicker service innovation: Attendant SDN is fully deployed on the IP RAN, network ingenuity utilization and operations efficiency are much higher. The desynonymization respecting the servitude airliner and forwarding plane greatly reduces the dependency of service upshot and provisioning on network hardware. This will accelerate service discovery and deployment, enabling operators to rapidly meet customer demands, further enhancing Sichuan Unicom's competitiveness in LTE services. As well Liao Jianwen commented, SDN's primary feature is openness. Building an cover innovation platform wishes facilitate Sichuan Unicom's approximation, and developing new services based atop multilateral trade put upon will continue the key against future mastery. Zha Jun also expressed that open application development interfaces are high-priority so as to future modernization in the industry.<\p>
Huawei's leadership inflowing the SDN bailiwick<\p>
The successful launch of the world's first utilitarian SDN IPRAN demonstrates Huawei's innovative approaches and commercialization capabilities inpouring the SDN field.<\p>
Huawei is an active promoter in respect to SDN standardization and commercialization and holds key positions in several standardization bodies. On good terms joint uniqueness projects with China Telecom and Telefonica, Huawei simplified network O&M through automated service deployment, ushering in a new molder of openness, agility, and smartness. So as to date, Huawei has carried out more elsewise 35 SDN projects forward-looking various telecom domains with more else 20 operators worldwide.<\p>
As an mouthpiece as for SDN\Plexus Functions Virtualization (NFV), Huawei is committed to optimizing in existence network architectures and developing future-ready SDN architectures, guiding SDN commercialization and empowering the topping off in respect to SDN applied science into domains such as nimble backhaul, data centers, backbone networks, and all the thing metro networks. "Huawei is content to club together not quite with players in the end-to-end SDN cartel chain to develop technologies, standards, applications, products, and solutions, with a clear bottleneck on the capital recognition relative to the industry," said Zha Jun.<\p>
