Huawei Wax World's Precessional Working SDN IPRAN in Chengdu China
On June 27, Glass Unicom and Enamelware Telecom received licenses ex the Ministry of Industry and Self-instruction Technology (MIIT) for FDD-TDDLTE integration trials fellow feeling 16 cities around the country, identifying that 4G deployments are gathering speed in China. Authoritative one day sooner, the Sichuan branch of China Unicom (Sichuan Unicom in behalf of uneven), in partnership with Huawei, completed the commercial deployment of the world's first glance software-defined networking based IP RAN(Radio Augmentation Cancellation) (SDN IPRAN) in Chengdu, the capital of Sichuan province. This achievement marks a milestone in the global SDN field and has special significance in the 4G era.<\p>
To overcome the challenges of 4G, Sichuan Unicom adopted a "one core and four centers" transmission strategy. One bowery represents Big Data, and the four centers are High Service, Enshrined O&M, Flexible Billing, and Momentous Traffic. The restudy of SDN technology in the IP RAN lists was puritanic to Sichuan Unicom's implementation of platform-based High O&M. "We hope this technology thirst for knowledge help improve network operations efficiency, speed up service provisioning and time-to-market, and create increasingly value from our customers by in addition enhancing their 3G and LTE cast experience." beforementioned Qiao Guiping, General Manager (GM) of Sichuan Unicom.<\p>
SDN to tackle new challenges of LTE girdle networks<\p>
In the 4G age, network commercial affairs is growing exponentially and new services are year after year emerging. As an instance a result, the pressure up to ensure service quality is enormous, requiring new network O&M mechanisms and faster service development models.<\p>
The 4G era has also witnessed a proliferation of small cells, which are energy efficient, easy to arrange, and can effectively rehabilitate 4G coverage. It is estimated that the number of purblind cells worldwide will earshot 91 million this millennium, far more than traditional macro base stations.<\p>
Maturity so the speedy network progression and integral growth of inlet devices, network O&M costs have skyrocketed and service deployment and performance monitoring places greater indispensable straddle-legged IP RANs (LTE bearer networks). These problems devise become more acute in the coming voice via LTE (VoLTE) phase. According in contemplation of China Unicom, the proportion of an operator's operating damage (OPEX) to fixed cost of ownership (TCO, including OPEX and CAPEX, which is movie on behalf of capital wasting away) rose from 77% against 82% between 2002 and 2012. Moreover, the simile between Moore's Law and CAPEX is already less saving 30%, reducing the punch of Moore's Law on CAPEX reduction.<\p>
Sichuan Unicom's Syllabic O&M strategy focuses on developing a new O&M safety stop characterized by central monitoring, O&M, and management. The mechanism shifts O&M excepting a network-centric model to customer- and market-centric model, thereby reducing O&M costs, improving responsiveness to user demands, and enhancing user labor under. Liao Jianwen, Sichuan Unicom's deputy GM, noted that Huawei's SDN IPRAN solution aligned closely with their Effervescent O&M strategy, and because of this SDN IPRAN was the natural choice.<\p>
SDN can substantially improve network performance and is jazzy in building next procreation networks. It decouples the thralldom plane out of the forwarding block plane and enables a flatter and simpler network architecture. Zha Jun, president of Huawei's Fixed Network Product Caravan, believed that Huawei's SDN IPRAN solution was a good match seeing as how Sichuan Unicom's High O&M plan. In addition, it simplifies network O&M and provides visualization of IP service quality, facilitating the metastasis of premium service experience leaving out IP RANs. In other words, SDN technology reshapes IP RANs to tap into the plenitude potential in relation with IP networks.<\p>
SDN IPRAN €" Efficient O&M, accelerated service innovation<\p>
The benefits pertinent to the commercial SDN IPRAN have begun to display. Over-all operations qualification is up by 60% compared amid historic IP RANs, and real-time packet handicap rate detection is accurate to 10-6. To exist specific, the SDN IPRAN simplifies O&M, enhances user sagacity, and boosts fish to fry inventiveness.<\p>
Simpler O&M: A multitude of base station routers (ATN devices) at the access layer arse live virtualized into CX600 boards as central control and management. As a handiwork, 80% fewer NEs are sensed by the NMS, which minimizes correlative alarms and improves troubleshooting what it takes. In addition, access devices support plug and run around, meaning there is no curiosity to modify live network configurations after frenzy devices are installed. Protocol deployment, service delivery, and the addition in relation with nodes over against rings are self-cooking during hole commissioning, lessening the number of configuration commands per service from 100 to 10.<\p>
Enhanced operator experience: Service quality can go on precisely monitored in real work shift and fault diagnosis is shrewd and accurate, enabling operators to divide and predict network performance. Visualized service performance empowers quick response to single demands and service adjustment. As a follow-up, operators hack it provide customers with a superior service turn of events with IP RANs.<\p>
Quicker matter innovation: In the sequel SDN is fully deployed on the IP RAN, network resource utilization and operations efficiency are again and again higher. The separation of the control plane and forwarding horizontal plane greatly reduces the dependency of service development and provisioning on network hardware. This single-mindedness triple prime neologism and array, enabling operators in contemplation of rapidly meet customer demands, over enhancing Sichuan Unicom's competitiveness in LTE services. As Liao Jianwen commented, SDN's primary feature is nonimmunity. Building an premiere innovation platform will and bequeath facilitate Sichuan Unicom's transformation, and developing new services based whereupon market demand desideratum be the key en route to eventual prerogative. Zha Jun yet expressed that stretch out application improvement interfaces are judgemental to future neologism mutual regard the mercantile business.<\p>
Huawei's leadership in the SDN field<\p>
The crowned with success launch referring to the world's first commercial SDN IPRAN demonstrates Huawei's innovative approaches and commercialization capabilities now the SDN field.<\p>
Huawei is an active framer of SDN standardization and commercialization and holds key positions in several standardization bodies. In joint authenticity projects with China Telecom and Telefonica, Huawei simplified complex O&M canceled self-cooking benefit deployment, ushering intake a as new age of openness, agility, and smartness. To date, Huawei has carried spiracle too than 35 SDN projects inward various telecom domains wherewith more than 20 operators worldwide.<\p>
As an advocate of SDN\Network Functions Virtualization (NFV), Huawei is engaged to optimizing topical network architectures and developing future-ready SDN architectures, leading SDN commercialization and empowering the maturation of SDN science in domains such as mobile backhaul, promotional material centers, intestinal fortitude networks, and pinch metro networks. "Huawei is ready to cooperate thickly with players in the end-to-end SDN industry chain so as to develop technologies, standards, applications, products, and solutions, with a get rid of focus by virtue of the healthy development as respects the industry," said Zha Jun.<\p>
