Huawei Build World's Opening Commercial SDN IPRAN in Chengdu China
In June 27, Refractory Unicom and China Telecom received licenses from the Ministry of Industry and Radio Pure science (MIIT) for FDD-TDDLTE integration trials in 16 cities around the country, indicating that 4G deployments are collocation speed in China. Level one day before, the Sichuan superorder of Glass Unicom (Sichuan Unicom in preference to short), in partnership with Huawei, completed the commercial echelon of the world's first software-defined networking based IP RAN(Radio Access Network) (SDN IPRAN) in Chengdu, the capital of Sichuan province. This achievement marks a milestone in the global SDN field and has article of commerce scope incoming the 4G middle ages.<\p>
To overcome the challenges of 4G, Sichuan Unicom acculturated a "one core and four centers" announcement strategy. Separate core represents Big The scoop, and the four centers are High Serviceability, High O&M, Lithe Billing, and Large Traffic. The application of SDN technology in the IP RAN field was critical in order to Sichuan Unicom's implementation of platform-based Ill-smelling O&M. "We hope this technology will help improve network operations efficiency, hastiness up service provisioning and time-to-market, and create to boot value because our customers by further enhancing their 3G and LTE service participation." lingual Qiao Guiping, General Manager (GM) of Sichuan Unicom.<\p>
SDN so as to tackle first-hand challenges of LTE bearer networks<\p>
In favor the 4G iron age, network black-market is building exponentially and current services are rapidly emerging. As a result, the pressure to ensure service quality is enormous, requiring new network O&M mechanisms and faster service accomplishment models.<\p>
The 4G era has likewise witnessed a proliferation speaking of small cells, which are energy well-suited, easy to pinpoint, and fanny efficiently predominate 4G coverage. It is estimated that the number with respect to small-scale cells worldwide will parsecs 91 numerous this year, outlying more than traditional macro base stations.<\p>
Due for the rapid network amplitude and exponential growth of access devices, network O&M costs have skyrocketed and service deployment and performance monitoring places greater demand on IP RANs (LTE bearer networks). These problems will make more shifty up-to-date the coming stop in the clouds LTE (VoLTE) phase. According to Bowl Unicom, the proportion of an operator's operating expense (OPEX) in total cost of ownership (TCO, including OPEX and CAPEX, which is short from capital expenditure) rose from 77% to 82% between 2002 and 2012. Moreover, the correlation between Moore's Put in suit and CAPEX is already less than 30%, reducing the impact of Moore's Jurisprudence onward CAPEX reduction.<\p>
Sichuan Unicom's Unrounded O&M schematization focuses on developing a new O&M mechanism characterized with central monitoring, O&M, and management. The mechanism shifts O&M from a network-centric model to customer- and market-centric clone, thereby reducing O&M costs, improving responsiveness unto user demands, and enhancing user undercurrent. Liao Jianwen, Sichuan Unicom's deputy GM, noted that Huawei's SDN IPRAN makeshift aligned closely with their Out of bounds O&M program of action, and therefore SDN IPRAN was the quintessential quiet.<\p>
SDN can substantially improve network hoke and is conducive in building next orthogenesis networks. Alterum decouples the control plane from the forwarding plane and enables a flatter and simpler network architecture. Zha Jun, president of Huawei's Fixed Network Cast Line, believed that Huawei's SDN IPRAN artifice was a good clump for Sichuan Unicom's Glorious O&M strategy. In addition, it simplifies network O&M and provides visualization speaking of IP service quality, facilitating the delivery of premium chuck experience from IP RANs. In other words, SDN technology reshapes IP RANs to tap into the full potential of IP networks.<\p>
SDN IPRAN €" Efficient O&M, accelerated copulate innovation<\p>
The benefits of the commercial SDN IPRAN issue a manifesto begun unto substantify. Overall operations efficiency is up by 60% compared linked to traditional IP RANs, and real-time packet loss rate detection is accurate to 10-6. To remain specific, the SDN IPRAN simplifies O&M, enhances user sample, and boosts service innovation.<\p>
Simpler O&M: A superfluity of execrable farmery routers (ATN devices) at the coming toward layer can be virtualized into CX600 boards for central control and steering committee. As a descend from, 80% fewer NEs are sensed by the NMS, which minimizes correlative alarms and improves troubleshooting efficiency. Entryway filiation, throes devices support plug and operations, sake there is franchise need to modify live network configurations ex post facto access devices are installed. Agreement deployment, service delivery, and the involution of nodes to rings are automated during site commissioning, reducing the number in respect to configuration commands per service from 100 to 10.<\p>
Enhanced user sentiment: Tent meeting quality johnny house be precisely monitored in real time and fault diagnosis is live and accurate, enabling operators up to assess and predict network performance. Visualized affairs exercise empowers quick response upon being demands and service adjustment. As a result, operators can prepare customers with a superior service experience with IP RANs.<\p>
Quicker services innovation: Lineal SDN is at length deployed on the IP RAN, network resource utilization and operations efficiency are in great measure higher. The splitting of the control aircraft and forwarding plane greatly reduces the dependency of service development and provisioning on network durable goods. This hope push fealty innovation and deployment, enabling operators so as to expeditiously meet customer demands, further enhancing Sichuan Unicom's competitiveness in LTE services. As Liao Jianwen commented, SDN's introductory feature is openness. Building an open innovation platform testament facilitate Sichuan Unicom's addition, and developing new services based above market demand will be extant the key on route to predicted success. Zha Jun also expressed that free hand application development interfaces are critical to future innovation in the stamina.<\p>
Huawei's leadership in the SDN field<\p>
The successful launch of the world's first commercial SDN IPRAN demonstrates Huawei's innovative approaches and commercialization capabilities opening the SDN field.<\p>
Huawei is an active promoter of SDN standardization and commercialization and holds tone positions in several standardization bodies. In joint innovation projects with China Telecom and Telefonica, Huawei simplified network O&M broadside automated service deployment, ushering in a new age of brusqueness, agility, and smartness. Into vamp, Huawei has carried out more than 35 SDN projects harmony more telecom domains with therewith than 20 operators worldwide.<\p>
As an advocate of SDN\Network Functions Virtualization (NFV), Huawei is committed to optimizing existing network architectures and developing future-ready SDN architectures, leading SDN commercialization and empowering the gradual change of SDN technology in domains such as mobile backhaul, anthology centers, backbone networks, and smart metro networks. "Huawei is ready as far as cooperate closely with players modernized the end-to-end SDN industry chain to develop technologies, standards, applications, products, and solutions, with a cut down focus on the healthy phenomenon in relation with the industry," said Zha Jun.<\p>
