Network Planning And Design Of SouFun

With the rapid development of the national economy, showed a modern enterprise group, a diversified development trend of enterprises are often the same across different regions, countries, the production, management products are often involved in many areas. They need to keep abreast of scattered around the branch of the operation, the same companies in different sectors, between different regions of the employees need to share in a timely manner, a large number of enterprises to exchange information. In addition, the business and its customers, as well as its business partners there are a lot of information exchange. All of this enterprise networks into practical business related to the survival and development of the issue. The computer technology, communications technology, to control the rapid development of technology, and enterprise networks to accelerate the application process, gone through a network of businesses from the terminal - the way the host to the client - server mode, and eventually to the evolution of the Intranet. Intranet is the use of Internet technologies and products of the establishment of a dedicated in-house corporate networks. Computer networks have the information and use of human civilization has brought a revolutionary change, since 1995 China Education and Research Network (CERNET) following the completion of the corporate network has entered a phase of vigorous development. The main local area network, including a variety of technical ideas, network design, network topology, cabling system, Intranet / Internet applications, network security, network maintenance and so on. The passage of the graduation project on the subject, so I hope the reader will understand the process of building the corporate network and involved in a variety of network technology and the future of everyone in the network to learn technical knowledge or corporate network to carry out the project in reference .SouFun have China's largest, most complete, up-to-date database of real estate projects, providing more than 45,000 national projects, the details of a strong housing search engine provides users with fast, accurate access to search properties for sale. China have the largest, most complete, up-to-date database of real estate information, daily news updates 1200, "recorded in the property sector here every exciting moment! Focus on the real estate sector all the man of the hour! The first time to grasp the pulse of real estate!" SouFun Chinese real estate industry has a technical level, the highest level of design of IT professionals, the most understanding of the real estate needs, cumulative national planning and design, production type of real estate Web site for more than 1,500. With the growing scale of business enterprises and the gradual popularization of Internet, intranet network to the information technology business is an inevitable choice, the enterprise network system is a very large and complex system, not only for the development of modern, integrated information Management and office automation applications, such as a series of basic operating platform, but also provides a wide range of applications, so that the information in a timely manner and accurately transmitted to the various systems. The internal network construction in the main application of network technology to the important branch of the local area network technology to the construction and management, this article will SouFun to the internal network planning and design process may be used in a variety of technical and implementation options for the design The direction of the enterprise network to provide the theoretical basis and practical guidance.In this paper, the use of computer network technology and the principle of SouFun for real estate information to businesses in transition planning and corporate network construction program carried out a preliminary technical analysis and discussion. The third tier backbone using Gigabit Ethernet technology exchange. SouFun building on the network backbone and structured cabling systems for the detailed design. According to the different requirements of long-distance network, the network's headquarters in Beijing on the proposed link with Internet access and two DHCP, VPN technology solutions. At the same time, this article on network security strategies and PDS made the initial program.The first chapter introduces the subject of the background of the company's profile, such as SouFun.The second chapter describes the company's internal network design, network-building goal, and that is the headquarters and branch offices in the building of local area network, wide area network connection and on the basis of Internet technology will be the introduction of a corporate intranet, so as to establish a unified, Fast, efficient Intranet system. In the whole system is safe, reliable, stable, in line with the principle of economy that is to achieve a reasonable investment, the largest output. Beijing headquarters as the center, and building on each floor, connected through fiber-optic, constitute a large-scale local area network classification. To Gigabit Ethernet as a backbone, the use of the third layer switching technology to achieve large-scale LAN VLAN division. Planning a 5 second node using Gigabit, and the main switching center (the main node) networks pose a gigabit backbone, the second unit (three-node) 100M using fiber-optic transceiver node access through the second backbone. Taking into account the loop network to connect up to effect redundancy, to increase reliability of the system, as far as possible between the secondary nodes connected to form a loop.The third chapter is talking about the internal network design, as a point of information throughout the planning of large-scale, up to more than 2700 clients, so we use DHCP distribution. SouFun 5-story office building, every floor of the core switches used HUAWEI 3600, this 5 HUAWEI 3600 final switch to converged Cisco 4506 switches. Each floor in order to be connected to the fiber layer together. VLAN information between departments can forward it to reduce the burden on the core layer switches, the switches in the core layer through the ACL (Access Control List) for the corresponding control, allows users to access the full control. Finally, the entire network of a security policy program.Chapter IV is the choice of equipment and detailed configuration. Outside the network devices used by the Cisco 2811, Cisco2811 series is suitable for large and medium-sized enterprises smaller Internet service providers to a series of modular multi-service access platform. The use of switches and Cisco 4506 models HUAWEI 36002. Every floor of the core switches used HUAWEI 3600, this 5 HUAWEI 3600 final switch to converged Cisco 4506 switches.Chapter V is the PDS. First of all, on the principle of cabling and wiring systems, wiring design put forward ideas on the transmission wiring design a detailed description, according to the integrated wiring system design specifications, we have the cabling system work area subsystem level Sub-systems, management sub-system, 3 sub-systems, equipment between sub-systems, such as sub-floors 6 module design, a complete set of systems to meet user requirements. At the same time, according to the actual situation when the building farthest from the point of information between devices (seat of the switch) less than 94 meters, the management sub-system and subsystem devices can be combined, the level of sub-systems and subsystems 3 can be combined, so Simplify the structure cabling system, facilitate the management of equipment, saving space and renovation costs. Finally, note the laying of the line.
