Customer background
Founded on December 29, 2002, State Grid Corporation of China is a key state-owned backbone enterprise that is responsible for the national energy security and the lifeline of the national economy. Its business covers an area of ​​88% of China's land area and its power supply population exceeds 1.1 billion. The company ranked No.7 in Fortune Global 500 in 2012 and is the world's largest utility company.
Customer challenges
The data communication network of the State Grid is an important infrastructure of the smart grid. The entire power generation, transmission, substation, distribution, electricity and dispatching are all supported by the information and communication network and belong to the entire power system's nervous system. At present, the development of smart grid urgently needs the leapfrogging of information communication platform based on the next generation Internet technology. The main problems are:
The rapid increase of smart grid terminal, IPv6 load is imperative
In addition to the traditional communication terminals and computer terminals of the public network, more are intelligent meters with industry characteristics, interactive terminals for power consumption, power grid control terminals, and scenery storage sensing devices. These devices are currently Every year, the scale of IPv4 is increasing. The IPv4 technology used in traditional networks is limited by the problem of address space. Therefore, it is urgent to expand network IPv6 capabilities to carry more services.
High reliability requirements, network transformation can not affect the business
First of all, the power communication network carries all aspects of the smart grid, which has a direct impact on the safe, reliable and stable operation of the power grid. Therefore, not only the performance requirements are relatively harsh, but also the requirements on the real-time, security and reliability of the entire information and communication network are also very strict At the same time, as the network structure of power private network is closely related to the power grid, the network topology is greatly affected by the power grid. In the power communication private network, the means of communication, communication equipment, communication models, interfaces, and switching modes are also complicated , IPv6 transformation can not affect the power grid business.
The next generation of the Internet is the key to ensuring the construction and operation of smart grids, enhancing business carrying capacity, business service capabilities, business support capabilities, security assurance capabilities and integrated management and control capabilities. SGCC responded positively to the call of NDRC in 2012 to launch the next generation of Internet in Smart grid applications.
solution
Through full communication with the national grid and demonstration of solutions, the advancedness and maturity of Huawei's IPv6 transition solution are affirmed. Finally, the NE40E high-end router serves the data communication backbone network and upgrades the existing backbone IPv4 MPLS integrated data network to support IPv6 Access and hosting. At the same time, we have renovated the substation LANs, application platforms, platform LANs and access networks in five pilot units in Shanxi, Ningxia, Qinghai, Liaoning and Jiangsu so that they all support IPv6 services. The overall Huawei network solutions have the following features:
IPv6 evolution of the best partners to support the successful completion of transformation of the grid
Huawei has long-term technology accumulation in IPv6 and its evolution. It not only provides end-to-end IPv6 solutions in areas such as Internet access, 3G, NGN, IMS / FMC, etc., but also fully supports dual stacks, tunnels and protocol translations Class IPv4-IPv6 transition technology. Huawei's DAQ equipment, boards and interfaces have all been tested by international authoritative IPv6 and have the capability of smooth upgrade to IPv6. At the same time, Huawei provides IPv6 professional services to help the national power grid to smoothly evolve to the IPv6 network through systematic and professional methods.
Reliability layers of protection, the whole network to further enhance the stability
The backbone of the transformation of the state selected the NE40E, which has a strong reliability, redundancy of key components at the device level backup, key components to support hot swap and hot backup, through ISSU, NSR, NSF and other technologies to improve business resilience and achieve non-stop business operations .
The network layer provides IP / LDP / VPN / TE fast reroute, fast detection of hardware BFD links, MPLS / EthernetOAM and other technologies to further improve the stability of the entire network while revamping the network. The network provides 200ms protection switching and reaches the global advanced level .
Since the research chip to create the industry's most powerful 400G routing platform to support the future expansion of the power grid business.
Based on the latest scalable 400G platform, the Huawei NE40E is a 40G to 400G / slot smooth expansion that is compatible with all line cards in the network. Currently, the NE40E is the most compact high-end routing device with the highest port density. The single slot supports 240G interface cable Card, a single cabinet up to a maximum density of 1320 * GE, give the network great. While the NE40E provides an H-QoS five-stage scheduling mechanism for the access side to meet the QoS guarantee of diversified and differentiated services. As the greenest 400G platform, each GE port consumes less than 9W and is 10% % Or more, supporting the ongoing business expansion of the power grid for the future.
