In the design of the webpage inside the shopping mall, I will design and implement it from the aspects of demand analysis, overall planning of the shopping center webpage, server construction, webpage management and webpage security. In the process of website construction, we will try our best to select stable and mature technologies and products, so that the website of the shopping mall will be in a stable state after it is fully operational. The popular three-layer web page structure will be adopted in the structure, as well as the core layer, communication layer and access layer. A star web topology will be used to access the main web page through the firewall. Taking into account the small scale of the shopping mall, fewer information contacts, and low information traffic, during implementation, the core layer mainly uses hardware and application technology to achieve its functions, and does not only use expensive hardware to achieve its functions. To realize web page functions, we must make full use of existing resources, do not waste, and do not blindly pursue high-end equipment. At the same time, taking into account the usage environment of the shopping mall, a rich application server should be established to meet the needs of information sharing. At the same time, taking into account the future development of the shopping mall, we adopt an open structure and technology to make the shopping mall website have good promotion capabilities and openness to meet the future development requirements of the shopping mall for the website.

Chapter 2 Key Technologies
2.1 Shopping Center Network Analysis
For the headquarters, a local area network should be constructed. Assume that there are two office buildings, the old and the new, the first conference building, the second conference building, a staff activity center, a multimedia center, and a shopping mall. In addition to the personnel activity center, each building has conference video services, and wireless Internet services can be implemented in the multimedia center and shopping malls. Outgoing police officers can visit the company's internal network. The old and new office buildings are about 460 meters apart, and the new office building and the two conference buildings are about 120 meters apart. The straight-line distance between each equipment building is between 60 and 460.

Figure 2.2 Network environment diagram
2.2 Existing networking technology
For the headquarters, is there a wired AP as the networking technology that should be adopted? , VLAN technology, virtual private network (VPN), hybrid fiber optic coaxial cable network.
2.2.1 Wireless AP technology
In wireless local area network (WLAN), wireless access point (AP) mainly completes the seamless integration of wireless web workstation and WLAN , which plays the role of relay expansion for wireless signals and provides wireless access services. Expanded spectrum communication technology is mainly used. The advantage of using this technology is to spread the signal to a wider frequency band to reduce the chance of blockage and interference.
2.2.2 VLAN technology
VLAN technology is an important part of switch technology and one of the important advances in switches. It is used to logically divide physically connected web pages into multiple subnets. Each VLAN corresponds to a broadcast domain, and hosts on different VLANs cannot communicate. Can be used to ensure message security.
2.2.3 Virtual Private Network (VPN)
A communication web page established on a public network and dedicated to an organization or a group of users, and its virtual performance There is no dedicated physical connection between any pair of VPN users. Instead, communication is accomplished through a dedicated web page provided by the ISP. Its specificity is demonstrated in that users outside the VPN cannot access web resources within the VPN, but users within the VPN can achieve this. Safe Communication. To facilitate corporate VIP users and business traveling staff to safely access corporate LAN resources through the public Internet.
2.2.4 Hybrid Fiber Coaxial Cable Network (HFC Network)
Uses digital and analog transmission technologies to provide general access to the Internet, telephone, analog and digital broadcast television and digital interactive transactions and other transactions. It combines computer web pages, cable TV networks and telephone networks to achieve "three networks in one", which has the advantages of rapid network construction, low cost, large transmission bandwidth and higher resource utilization rate.
2.3 Backbone network technology suitable for large shopping malls
2.3.1 ATM asynchronous transmission mode
ATM is used by people to satisfy their broadband needs Produced by the communication needs of the integrated business digital network, it provides a transmission, multiplexing and exchange technology for broadband integrated business digital signals, allowing language, data, graphics and video to be transmitted in a single cell with a constant cell length. Transmission in the network improves the transmission speed.
ATM’s unique bandwidth and predictable performance adopts cell switching technology, which can provide users with unique bandwidth (can support between 1.5Mbps and 2.4Gbps). transmission speed), adjustable bandwidth, small web page delay and other features. As the backbone of large shopping malls, ATMs have the following advantages:
1) ATMs are easy to expand to extremely high speeds;
2) ATMs provide VLAN functions and can provide equipment-to-device communication Extremely high throughput;
3) ATM provides extremely strong error redundancy function;
4) ATM provides minimal error for real-time voice and image transmission Delay;
At present, WAN basically uses ATM equipment, and the backbone of large shopping malls uses ATM technology to easily achieve seamless continuity with WAN.
ATM is highly regarded for its perfect service and quality. In addition to providing general instant communication services, ATM also provides some advanced services, such as long-distance video conferencing, real-time image transmission, etc. However, ATM is a brand-new technology. Users who adopt the ATM website must purchase new experimental tools, train staff, and the ATM fee is relatively high. At present, most ATMs are only used in backbone networks with high requirements, to desktop or Ethernet. net.
2.3.2 Gigabit Ethernet
Since most local area networks currently use Ethernet, and all web operating systems and surface protocols are compatible with Ethernet, This makes Ethernet still the mainstream of the future. It accounts for a huge proportion of many Fast Ethernet networks, so upgrading from 10BASE-T to 100BASE-TX is easy and can be completely seamless. Therefore, the standards for Gigabit Ethernet have been basically set. Today, Gigabit Ethernet has become the first choice for the backbone of various enterprises.

Chapter 3 Requirements Analysis
3.1 Business Requirements
During the entire web development process, it should be ensured that the designed web page can meet the user's business needs. . The web system provides services for a group. In this group, there are independent functions and different business needs.
3.1.1 Determine the organizational structure and network investment scale
The shopping mall system adopts a management plan that combines intensive and distributed management, that is, at the headquarters Establish WEB services and install corresponding management programs. Install real-time transmission tools in each branch and connect to the headquarters server through the web page. Complete the entry, interrogation, accounting, etc. of general transaction notes. Core web pages, converged web pages, access networks, centralized cabling, computer room construction, etc. are one-time investments. From the increase in sales volume and the increasing number of consumer groups, business demand continues to rise, and branches may be opened in several other provinces. The scope of the web page has also expanded, and the scalability of the current web page needs to be taken into consideration. Clear long-distance communication or clear telecommunications rental, training fees, web page maintenance fees, equipment maintenance fees, etc. are all prices that shopping malls need to consider. Not just the price of core switches and routers.
3.1.2 Communication volume requirements
The communication volume of shopping malls mainly comes from two aspects. One is the sharing of ordinary files or printing and sharing. These are only A bandwidth of 1Mbit/s is enough. Shopping mall surveillance systems or multimedia video services have high communication requirements, which generally require bandwidth above 10Mbit/s.
Considering that shopping malls may build powerful remote purchase systems, some backbones within and outside the province have higher bandwidth requirements. Single-mode optical fiber should be used to ensure long-distance cabling.
3.1.3 Determine the reliability and availability of the network
Considering that there are multiple branches in a city, ensure the timely transmission of web data and there will be no warehouse products It has been shipped out of the warehouse, but the system has not yet recorded the event. When there is a clear obstacle, clear switching is immediately realized. In particular, core switches should adopt link redundancy technology.
3.1.4 Determine the security of the network
If the information of the Ministry of Finance is not disclosed to the outside world, it will only be disclosed to some internal personnel. Different VLAN strategies can be used in shopping malls. It can not only enable all departments to work normally, but also conceal information. But the information of most web users is not confidential, so it is enough to provide common security technical errors. For web pages with special transactions, strict security controls are required for personnel.
3.1.5 Determine the remote access method
Consider that large shopping malls may have stores in cities across the province and other provinces, which can be implemented at any time and at any location. To access the web resources of the headquarters, you can use encryption technology and VPN technology to access internal web pages from remote sites.
3.2 User needs
3.2.1 Collect user needs
Find out the important services or functions that users need. These services may require a web page to be implemented, or they may only require a local computer to be implemented. For example, it is necessary to install an automatic query system in each shopping mall. For example, a certain user can use a computer in the shopping mall to query the location and cost information of the items he wants to buy.
3.2.2 User Service Table
Similar to a memo, the user service table should be used to correct mistakes and errors in information network work at any time when network users need it.
3.3 Application requirements
Common application requirements in large shopping malls include Internet access, email, images, video transactions, voice transactions, office automation, etc.
3.4 Network requirements
3.4.1 LAN function
The previous LAN page consisted of a Layer 2 switch as the backbone of the LAN. A web page is a broadcast domain. In such a web page, the network segment is formed by a shared device connected to a port of the switch. Communication between users within the network segment does not need to go through the switching device, but inter-segment communication needs to be stored and forwarded through the switching device. Modern LANs are composed of three-layer switching equipment to form the backbone of the LAN. There are multiple broadcast domains in this kind of network, which are actually multiple small LANs. These small LANs are interconnected through the routing switching function of the three-layer equipment.
Regardless of the network segment, it is a method of distinguishing computer nodes. However, the current network segment separation methods based on three-layer switch technology are gradually becoming more and more popular.
During a day's trading in shopping malls, the highest transaction traffic is generally concentrated around 9 a.m. and 8 p.m. at night. We can obtain web traffic analysis on existing web pages through various experimental tools (such as HP OpenView, IBM Tivoli NetView) to obtain the current web page load as a reference for web page upgrades.
3.4.2 Data backup and disaster recovery center requirements
For some specific industries, data is very important. Once the data is lost, it will lead to disaster. Recovered loss. Shopping malls are no exception. Data such as the Ministry of Finance, Purchasing Department, and daily business volume are key contents. It adopts network access storage (NAS) and storage area network (SAN), and can also use high-end IP SAN technology.
