In recent years, Internet INTERN has a wide range of concerns arising from enterprises. To form an enterprise internal network intranetETTET to quickly use the idea of Internet technology in society (on the Internet, the advancement of Internet technology is applied to the enterprise LAN (LAN) In someone calls it, it is called a fashion.
As a unit of intranet in a unit, it has established an internal information of the enterprise, and some methods and strategies of the enterprise have been used, and some methods and strategies using a project are inspired: the technical backbone of the heart, I am fortunate Independently completed the development of some software. The solution system and FTP file transfer system, and VPN technology uses Internet network energy access and some of our measures to introduce the overall plan design, and after organizing, the original business application system and subordinate units are integrated. A network interconnection is implemented, and the Intranet of the head office is realized. Now, this will be implemented, hoping to build a small and medium enterprise intranet
Basic situation: 1. Application order is a group's distribution of the group to be the main combined logistics as a customer service. A foreign transport group is mainly engaged in the transportation of import and export goods in a certain port branch. Trade and transportation enterprises, is a business transfer agent to enter and export goods.
2. Computer application: The current enterprise has a bureau to lose agent business system, for Visual FoxPro 5.0 statistics software, office software (Office). City Network, NT 4.0 platform, running core application software for container development network multi-user systems. There are other personnel, finance, and there are 4 special computer applications.
The implementation of the Intranet network of this unit is mainly for the process of the case, we mainly carry out the following policy options in the system of information in the system. In the implementation:
1. Network Construction Plan: Single far can't meet the needs. The unit has a warehouse and a container station phase, first of all the lines of the office building, 100M bandwidth, 125 letter HUB adopts several 3COM 16 HUB units and box stations, and use dialing methods). Since the unit is more PC, intranet's basic protocol TCP / IP bit has a city network, 25 information points 6 layers of office buildings, requires people to do one machine, the same. The leadership, middle-level cadres, etc. have requested integrated wiring projects due to non-interest points of office buildings. The switch uses a 12-port 3COM 3C5. The Cisco 3600 is used as a router. The combination of frame relay FR with Beijing has a huge Windows user group, so network protocol. . However, with the high requirements of information construction, it has been required to meet with three grassroots units (teams, outside the corresponding data and various queries. For this order, the concentrated line is set, using 092A 10 / 100M Adapt to equipment, sharing, 4 wide area network ports are connected to 4 remote base headquarters (because of funds, there is no new platform for Temporary platforms.
In addition, the office building can be used in a scheme with junction work. If there are several building groups to implement P & S wiring. Configuration wiring, big logarithmic cable is the main dry, the main workshop, each with a campus network, can be used to do the main network (FDDI), then in each
2, the selection of the software platform: Source code OS) C, based on Microsoft, support Microsoft platform soft Windows NT4.0 as a network fucking intranet online browsing platform. Phase Server is with NT platform and excellent SQL Server6.0 As a database, it is entirely competent, just considering the current popular Intranet platform, there is a platform Windows NT. Considering that SME manufacturers and make it easy for users to easily operate, with the small large database of Sybase, ORCALE, INFORMIX, with the Sybase, Orcale, Informix, in addition, using Linux platform technology to learn To break the time, and use, Based on UNIX, B, based on Linux (the characteristics of the open industry, the available third-party software for the GUI interface, we have chosen as the web platform, IE4.0 as customers, DB2 Wait for large databases because SQL small and medium-sized enterprises are more suitable, they will choose the current is also very popular. It is also not adopted from technology. 3. Some web applications should be developed because of our own technology Intranet Web application and technology, server page), ODBC (Open number above, taking into account the software in the future, and facing the software in the foreign industry. Development platform for Visual Basic / The number of procedures, the number of original application systems, such as CGI ( 冢 (by library interconnection), RDO / ADO (ActiveX degree and efficiency, I suggest adopting ASP plus ADO mainstream development technology. Goods. Product The software is less. We plan to open Front Page / HTML Editor, due to importance. You need to grasp the corresponding interactive development technology application programming interface), ASP (active Data Object active data object). The technology is developed. And This is current and
4, the interoperability of the internal network and the external network will not exceed 15 people. We use (Proxy), you can achieve on-demand and security considerations: due to the less expensive ISDN-line communication method, the number, HTTP proxy, FTP Agent, telne, the number of concurrent users in the Internet generally uses a PC installed a proxy server software T agent, SMTP / POP
Mail agent, user management, etc., can be able to have a fast slow way, but due to the reasons for funding, it will make the company's internal data, machine, and application system. Of course, use DDN mode, apply for legal IP addresses to set up the agent. Due to the interworking of the internal and external network, if there is no certain security machine to be a virus or hacker attack or unauthorized access.
The security technology in the inside and outside has a pack filtering, and the fireproof appliance has some security mechanism and internal data has more funds in this regard. In the internal local software, there are many companies that are safely installed in the server side and the client, such as Wang Jiangmin's KV series, Rui Wall, security agent service, etc., due to our choice of soft security measures, management system, backup OK can be done. Therefore, we haven't online, we chose the NET VRV (50 users) network version of the anti-virus to ensure the security and reliability of the intranet. Currently, you can choose from a network star.
5, the original system and the I-type database, the selected Web should be used by a software to be used from application system servr to the background, and the integration of web interaction NTranet technology: Since the original application development environment does not directly operate FoxP The data inquiry system to be managers and leadership will be in the middle. The system is based on FoxPro, the database is a text RO database. In this regard, we have additionally prepared in the introduction of SQL Server, and SQL
6. The connection with the Group's headquarters is not high and the funds are difficult to build intranet network, and the LAN users of the branch by using the inhernet network, and in this basis. It is changed to the Web application: now WIONDOWSNT4.0 supports an application, it is undoubtedly a more router is straight through DDN and Internet. Based on this link, run the PPTP protocol (and verification Realize the web site of the Intranet network of the head office. New technology is the VPN (virtual private network), for the implementation plan, due to the headquarters of the headquarters, the company has the company's company Non-PPP protocols), virtualized a data channel, connection with the branch lan. The current application is a bit. At the same time, after the full-system business statistics software also runs in the company, the process of the company's users. At the same time, the construction of the network It is very convenient to carry it very convenient. The original application system data is also reduced in maintenance cost. At the same time, intranet successfully received the single system of customer interface (IE), simplifying user training learning, information and documents Flow speed, file, data is uploaded, and IE browse. Some web applications have enabled the client's operation, which also enhances our information department.
However, due to the nature of the unit, some applications have passed the simple, utensils, and one primary domain NT server, which is seriously used by better method, generally used all parties to improve; perhaps, using software public Many limitations of scale, such as cost, use, and low strategy. We only have fewer machines, no domain allocation;, we have simplified handling; use the total company's total sales period; in addition, in the cooperation of the company, ISP, etc. System Analysis Ability, etc. Web server, one SQLServer service is connected to the application system department of the original file type database, the speed is slightly, and the peak block leadership spending money and pays attention to the attention of the company. Intranet network. Great.
In view of the above reasons, I think our company's intranet network will make the following improvements in the future:
1. Improvement of communication lines: Head, branches and base units will use DDN / FR and even optical cables, and the gradual decline in DDN / FR or even optical cables, and branches and special lines.
2. Software application mode is developed from DOS single users, file secondary direction, our unit, future should be widely used in object-oriented OOP, COM / DCOM composition, also take cooperation reliability, etc. It is difficult to reach the high software engineering to use UML modeling technology), strengthen project management, team-type database multi-user, C / S, to B / S structure, three-layer structure, and multi-layer upgrade can directly use B / S structure , Three-layer structure, in development technical parts, ADO database connection object, ASP technology. And the development side or the form of development, otherwise, the quality of the software has been developed, and in addition, it is necessary to analyze and rebuild the mold in the development of medium weight demand (can be collaborated.
3. In 1-2 years, the firewall is established between the densely intermoded.
