Overview of the Three Gorges Power Plant
Three Gorges power plant is the world's largest hydroelectric power plant, the world's most magnificent Three Gorges Dam and the Three Gorges Reservoir, more than 1,000 Internet users. Yangtze River Three Gorges Project, is the key to harnessing and developing the Yangtze River project, and the construction of the Three Gorges power plant is a core part of the Three Gorges Project. Three Gorges Dam nearly 200 meters high, making the Three Gorges abundant water resources can be fully used. Three Gorges Dam and the Three Gorges Reservoir is based on the Three Gorges power plant is the world's largest hydropower station, the total installed capacity of 18.2 million kilowatts. Annual power generation capacity of 84.7 billion kwh, equivalent to 40 million tons standard coal energy.
Network-building needs
The enormous size of the Three Gorges Project has its various departments scattered layout. The power plant has eight large office areas, far more than 40 km apart, each office and the office buildings to be connected. Three Gorges Power Plant (chip) is attached to the Three Gorges Corporation, a large department, there are three office buildings scattered within the range of two kilometers, more complex network applications, the high bandwidth requirements, is the Three Gorges Project Corporation internal network (Intranet) one of the branches.
Technology Solutions
Why 3Com
3Com Corporation as a global market leader in networking, network products, has been leading technology and market share, widely praised by users as the Three Gorges power plant equipment selection, of course the network of choice.
In the choice of equipment manufacturers to take into account the maintenance of products, services and upgrades, integrators and users have to consider the company's strength and business conditions, compared with other vendors, 3Com Corporation has a more solid strength, always have a good results of operations, to the user to stronger confidence. 3Com is also a major reason for selection.
True to the Three Gorges power plant and inviting experts and leaders is the 3Com Switch 4007 switches are the "five guarantees":
1. Practicability to ensure:
3Com 4007 switch is designed to meet the needs of modern business design, and application of the latest switch technology products, providing network backbone and high-density integration of the desktop build high-speed local area network access solutions. She will support the latest enterprise business applications to ensure network availability, and can access the network anytime, anywhere. The most important thing is that it's a direct forwarding and pre-set function makes installation and commissioning is also very convenient.
3Com 4007 switches are designed to be very flexible, ideal for building backbone (or as the core switch) the best choice. 3Com 4007 switch can provide customization, priority queue service and network security control, and can adapt quickly to changes in data growth and the need to meet the needs of users. Demand for more network, 3Com 4007 switch not only mass data and control information can be conveyed, more scalable hardware and software redundancy features to ensure users a highly reliable network.
2. Scalability ensure that:
Starting from the selected 3Com 4007 users can easily expand its backbone network to meet the needs of business growth. Users can install the redundant management module to increase power and reliability, can increase the optional I / O modules to further customize the 3Com 4007 switch. 3Com 4007 switch can support up to 216 Ethernet / Fast Ethernet port or to support up to 54 Gigabit Ethernet ports.
3. Openness and standardization:
3Com 4007 switch to the network administrator to provide more tools to control data flow, optimizing customer service. The logical layer, 3Com 4007 switch supports IEEE 802.1Q VLAN (Virtual LAN), allowing administrators to limit the local flow of data to ensure the sector, the Working Group on data flow security. The system also supports sub-switch port or protocol based VLANs. Full support for IP, IPX and AppleTalk routing function, the third sub-network management layer, providing a third layer of data transmission between the various segments of security control. Since the switch can interpret the data packets in the high-level information to support packet-based MAC address, IP address, port number and other information set packet filter, complete management and control data Liu.
4. Reliability and advanced nature of assurance:
3Com 4007 switch in the device layer and network layer to support critical business networks provide high availability. At the device level, 3Com 4007 switch with exchange and management of distributed processing features, so the data flow of the operation and management does not depend on any single part. Important parts of the system, such as management modules, power supplies, fans, etc. can be configured for redundancy. When a fault occurs, can be restored in the second-level system uptime. All modules are hot-swappable, hardware replacement guarantee does not affect the network during normal operation.
5. Management, operational simplicity:
At the device level, 3Com 4007 switch to the distributed agent model, in exchange engines, I / O modules, and other equipment level components with independent 3Com SmartAgent intelligent devices, it conducted a special for each device optimization. The embedded management devices and systems to support a wide range of standard Simple Network Management Protocol layer (SNMP), management information base (MIBs), so, so that 3Com 4007 switch can manage specific information, such as buffer management of data, data traffic statistics, exchange / routing status information and so on. This distributed network management agent also allows the switch is independent of central control of decision management applications. For example, when testing the network event occurs, for local processing operations or direct access to special resources such as RMON (remote monitoring) probe.
