Nokia and Jiangsu Telecom, a regional branch of China Telecom, are deploying China's first commercial Carrier WAN-SDN project in data centers in Yangzhou, Changzhou and other cities in Jiangsu, a neighboring province of Shanghai. The deployment will help Jiangsu Telecom achieve seamless, transparent and flexible management of Internet Data Centers (IDC) in a unified manner.
The popularity of cloud technologies has revealed the limitations of previous IDC router technology, showing that it fails to support a seamless connection with the WAN and meet ever-growing data demand. Older technology also keeps IDC management and maintenance efficiency at a low level, hindering the development of Internet services.
Jiangsu is deploying Nokia's Networks Services Platform (NSP) to program its powerful core network router, the next-generation 7950 XRS (Extensible Routing System). The XRS provides the large capacity along with programmability to build the core that connects the datacenters. The NSP is then able to program the core to optimize the use of the resources by load-balancing the traffic and adjusting to changing traffic demands. As a result, Jiangsu Telecom will dramatically increase the flexibility of its network, reduce overhead costs, meet the ever-growing data demands of its subscriber base and support various application scenarios such as accessing and connecting IDCs. Jiangsu will also be able to pave the way for the future development of applications including High Definition video, IoT and smart homes.
Wit the Carrier WAN-SDN, Jiangsu Telecom can achieve unified, seamless, transparent and flexible IDC management to strengthen network flexibility and efficiency, while reducing operational costs.
The 7950 XRS, based on a highly programmable Network Processor (NP) architecture, provides the capacity and capabilities needed as service requirements evolve.
Nokia's NSP adjusts and optimizes network traffic using standard protocols such as OpenFlow, optimally directs network traffic to balance load and maximize efficiency and performance. Nokia's NSP and 7950 XRS help Jiangsu stay ahead of increasing data requirements and support various IDC application scenarios.
“As IDC network loads get heavier, operators are turning to cloud-based technologies to balance their network and make IDC management more efficient, flexible and seamless,” said Mike Wang, head of the joint management team of Nokia Networks China and ASB. “Our NSP and 7950 XRS will let Jiangsu Telecom distribute its broadband resources intelligently and dynamically, and make its networks more agile, scalable and efficient.”
