Tapping into a Goldmine of Information

--Huawei's WAN Project for CNPC

The China National Petroleum Corporation (CNPC) has been implementing the national strategy of converging modern industrialization with an increasingly information-based economy and society. CNPC has committed to an information-based enterprise transformation to meet its objectives of growing into a multinational comprehensive energy corporation. As the Chief Information Officer (CIO) of CNPC explained, informatization has become a part of CNPC's system and culture.

Recipe for Relieving the Pain of the CIO

Currently, CNPC has a unified information network, which is large enough to cover 12 regional network centers in China and five regional network centers outside China. The network supports seamless connection of more than 200 member companies, laying a foundation for the efficient and stable running of information systems. The CIO, as the executive with overall responsibility for CNPC's information issues, has a long list of responsibilities, as well as his share of worries. The wide area network (WAN) of CNPC is required to carry important data and applications for daily business and operation of the corporation. Such data and applications include the e-mail system, antivirus system, enterprise resource planning (ERP) data, teleconferencing, e-business, Internet access, and office automation. In addition, there is other data from exploration and production companies.

As the company and its business become increasingly information-based, the enterprise network has to carry more applications and data. The CNPC WAN has been limited by weak infrastructures and insufficient link resources, falling short of the requirements for various applications to go live. As a result, CNPC was in urgent need of network reconstruction.

To address this issue, CNPC initiated the WAN reconstruction project. According to the CIO of CNPC, WAN reconstruction would be a huge project involving many aspects and complicated technologies. Based on the current status of the WAN and the future requirements for data transmission, a hierarchical network architecture would be adopted to suit the future development of the WAN. According to the design, the 200+ regional companies would connect to the 12 regional centers nearest to them. These regional centers would, in turn, connect to the CNPC headquarters in Beijing. In this manner, the current network links, devices, and human resources of CNPC would be fully utilized. The overall quality of service (QoS) of the CNPC network would be improved and network benefits maximized.

Tapping into a Goldmine of Information

Starting from 2008, the project took three years to complete.

The project exclusively deployed approximately 100 sets of NE80, NE40, and NE20 routers across the WAN. The carrier-grade core router NE80 is deployed at the CNPC headquarters in Beijing. The universal switching router NE40 is deployed at regional centers. In both cases, Resilient Packet Ring (RPR) is used for WAN reconstruction. The high-end multiservice router NE20 is deployed at regional companies. The three series of routers cooperate closely with each other, forming an IP network with a complete structure and clear layers. The redundant deployment of all nodes and links enables the entire network to be highly reliable and free of single-point failures.

The Huawei NE40 series inherits the design concept and key technologies of the core router NE80. The NE40 is a highend network product for large enterprise networks, industry networks, IP Metros, and IP backbones. Based on distributed hardware forwarding and non-blocking switching technologies, the NE40 boasts line-speed forwarding performance,

excellent scalability, an effective QoS mechanism, and good service processing capabilities. In addition, the NE40 is superior in its convergent access capability. By virtue of its diverse features, L2VPN, L3VPN, multicast, multicast VPN, MPLS TE, and the QoS mechanism can be deployed on the NE40 so that the network can carry services in a reliable way. Moreover, the NE40 supports IPv6 so that the network can smoothly evolve from IPv4 to IPv6. As a result, the NE40 can be flexibly deployed at the edge or core of an IP/MPLS network. Simplifying the network architecture and providing diverse and reliable services, the NE40 is regarded as an important driver for the IP/MPLS bearer network to undergo a secure, intelligent, broadband-based, and service-oriented transformation.

Voice of the Customer

"Huawei has provided us a manageable WAN transmission solution featuring high security, high performance, and low cost. This solution can fully meet CNPC's requirements for handling multiple services and 'big data', enhance our business processing efficiency, and sharpen CNPC's competitive edge."
