With the improvement of people's own quality, reports are closely linked with our lives, and reports have the characteristics of two-way communication. Actually, writing a report is not as difficult as you think. The following is the opening report of campus network planning and design compiled by me for reference only. Let's have a look.
Campus Network Planning and Design Opening Report 1 I. Basis of Topic Selection
With the development of computer network to 2 1 century, the planning and construction of global information expressway has reached a climax. As its embryonic form, there are nearly ten million computers connected to the Internet, and hundreds of millions of people all over the world exchange information and handle various businesses on the Internet. A large number of information resources have been accumulated on the Internet, involving the information of various fields, industries and social public services that human beings face and engage in. Become the world's largest information base in the information age.
Campus network is the main branch of all kinds of networks and has a very wide range of applications. As the birthplace of new technology, schools, especially colleges and universities, have a close relationship with the network. The network was first successfully experimented in the campus, and many new network technologies were first successful in the campus network before being introduced into the society. On the other hand, as a "high-tech incubator", schools are rich in knowledge and human resources, and are more eager for information than other industries, hoping to obtain all kinds of information through channels and promote their own research and academic progress.
Because of the close relationship between network and schools, China has been connected with hundreds of schools in China since 1994 CERNET was officially launched. It provides a brand-new network environment for teachers, students and researchers. 1998 10, the second phase of China education and scientific research network (CERNET) was officially launched, and the second phase was completed in 2000, which not only achieved the goal of 1000 colleges and universities networking, but also provided internet services for qualified primary and secondary schools. Indeed, with the rapid development of information technology, the construction of campus network in primary and secondary schools has been gradually put on the agenda. However, at present, most of the campus network applications in China are not rich, and some computer business systems in schools have not been fully utilized. Low application level is a great waste of campus network resources. Only by improving the application level of campus network can we effectively improve the school's business level and adapt to the requirements of the information age.
At present, with the support of the 2 1 1 project of the State Education Commission, all colleges and universities in China basically have their own campus networks. At the same time, the campus network construction of professional/vocational colleges and primary and secondary schools around the country is also in full swing. Therefore, how to plan, design and maintain the campus network is the primary problem faced by all schools at present, and how to make efficient and full use of the resources of the campus network is related to the overall value of the campus.
Second, the research objectives and main contents
1. Principles and objectives of campus network construction;
(1) system design principles:
(1) practicality: it refers to proceeding from the actual situation, so as to achieve the purpose of convenient use and benefit.
(2) Advanced nature: refers to the adoption of the current international advanced and mature mainstream technologies and relevant international standards. If the equipment selection is advanced and serialized, the system should be scalable and easy to upgrade.
(3) Security: refers to adopting various effective security measures to ensure the safe operation of network systems and application systems. Security includes four levels: network security, operating system security, database security and application system security.
(4) Scalability: refers to the adoption of protocols and interfaces that meet international and domestic industrial standards, so that the campus network has good openness, realizes interconnection with other networks and information resources, and can increase nodes and subnets at different levels of the network.
(2) Network design objectives:
Mainly used in multimedia teaching, administrative office, student status and personnel management, book management, financial management, information sharing, video on demand, WEB services, electronic bulletin, scientific research and technical exchanges, and Internet applications.
2. Overall framework of campus network
Use drawing tools to draw the plan and network topology of the whole campus. It provides a basis for network planning and design.
3. Campus network planning and construction scheme
According to the campus planning and network topology diagram, the specific implementation scheme is planned and designed reasonably by using the learned knowledge.
4. Design of campus network application system.
According to the actual situation of school teaching and teachers' work and study, the campus network should have the following application systems:
1. E-mail function and office automation
The campus network information platform should have a powerful mail system and OA system, which can establish its own mailbox and OA account for each user, which is safe and confidential and greatly facilitates communication. Many transactions can be reminded by email and OA, which is efficient and convenient.
2. Electronic library
With the electronic library, all materials can be stored in the form of electronic documents on a large-capacity server, and opened to the library or even the clients in classrooms, offices or dormitories through the network, so that teachers and students can consult the required materials at any time without the limitation of time and space, and the same resource can be shared by many people.
3. Online video
VOD(VideoonDemand) is the abbreviation of video-on-demand technology, also known as interactive TV on-demand system. When you turn on the TV, you can directly order the program you want to watch at any time, without watching advertisements or running for a program, just like playing a new movie that has just been put into your home video recorder or VCD player, but you don't need to buy a video recorder or VCD disk, nor do you need a video recorder or VCD player. This is your dream brought by information technology, sending video programs to thousands of households according to personal wishes through multimedia networks. For campus network users, the school can provide multimedia video-on-demand teaching services. By putting good courseware on VOD server, students can flexibly carry out on-demand teaching services and turn boring classroom teaching into rich media services.
4. Wireless network
Generally speaking, it is impossible to set too many information points in classrooms, libraries, conference rooms, playgrounds, canteens, campus parks and other places. However, with the popularization of notebook computers among students and modern teaching, there are often a large number of computers in these places at the same time, and the current wired campus network can not make students surf the Internet in these areas. By connecting wireless access devices at limited information points in a wireless way, it can be easily expanded from one information point to hundreds of information points.
5. Broadband Internet access
In today's information age, people have regarded the network as an important source of information, and WEB applications have played a decisive role. Most people gain new knowledge by browsing the web. Campus network should be the forefront of broadband internet access. Students can gain a wealth of knowledge through the Internet, and increase opportunities to communicate with students from other schools and even other countries.
5. The security design of campus network
According to the economic ability of the school, you can choose to install firewall software and hardware and some technical means of safety management to complete it together.
1. Security functions of routers and switches
Various authentication and packet filtering. For example, authentication of PPP protocol: PAP, CHAP.
2. Safety measures
A. firewall technology based on packet filtering B. Log function
C.NAT network address translation technology d.IP address -MAC address binding technology
E. dynamic routing protocol authentication technology F. access control G. ARP attack prevention
3. The security of the host
Keep the operating system and antivirus software updated in time; Install the appropriate tested patches.
6. Campus network system budget.
The construction cost of the whole campus network must be within the financial capacity of the school, and the overall performance of the network system should be improved as much as possible.
Three. Research methods, research means, technical route and experimental scheme to be adopted.
The planning and design of campus network is related to a series of problems such as teachers' teaching, principal's office management, teachers' and students' lives, so planning and designing campus network is a problem that must be solved. This topic mainly solves the following problems of campus network:
1. Functional design of campus network
The main functions to be realized are: multimedia teaching, electronic library and internal information sharing to meet the daily management of various departments of the school.
2. Campus network wiring design
According to the school environment and the school's economic ability, choose all kinds of cables reasonably. In order to realize high bandwidth transmission, the backbone network will take 10 Gigabit Ethernet as the backbone, Gigabit optical fiber to the building, and 100 Gigabit bandwidth to the desktop.
3. Campus network security issues
Campus network, especially the campus network connected with the Internet, network security is particularly important. Because a malicious destruction or the wrong operation of managers will bring huge losses. Therefore, on the one hand, it is necessary to strengthen the technical training and relevant legal and moral education of managers and users, on the other hand, it is necessary to establish an effective software and hardware monitoring and protection system.
4. Campus network maintenance
In order to ensure the stable operation of the campus network, daily maintenance is essential. Regular inspection and maintenance of network equipment, backup and update of network system mainly solve the problem by the following means:
1. Dividing VLAN in the whole network is not only convenient for management, but also can enhance the security of the network. VLAN(VirtualLocalAreaNetwork) is a technology based on switching technology, which divides the machines and equipment in the local area network into different network segments logically rather than physically, and realizes the division and management of logical working groups by software.
2. Subdivision can use the addressing of each type of network more efficiently and solve the problem of address waste.
3. Address translation. Generally, we can only get a limited number of public IP addresses from ISP, which is far from enough. In order to meet the network needs of all teachers and students, address translation is necessary. In other words, the private address assigned by the user is converted into a * * * address, so that the Internet can be accessed.

Fourth, the writing outline
Chapter 1 Campus Background and Status Quo
This paper briefly introduces the enterprises that implement network engineering projects, including the general situation of the school, the introduction of various departments and functions of the school. The application status of campus network and the demand of the school for network development.
Chapter II Demand Analysis
Including network application requirements, security requirements and technical requirements, the application requirements include how to access the network, so that all students can obtain resources and information through the Internet, and the school network needs to realize office automation; Security requirements need to select a certain amount of traffic to pass through, use firewalls to ensure the security of enterprise networks, divide security subnets, and strengthen access control of network boundaries. Technical requirements, in order to ensure the performance and safety requirements of the school network, the information points of the main buildings of the school are coordinated and planned. Establish a network center and install corresponding servers and routing switching equipment.
Chapter III Network Design and Planning
Practicality is the first principle of network system construction, and the network must meet the demand to the maximum extent and ensure the quality of network service. In order to standardize the design, technology and equipment selection of the whole network, and ensure the future requirements of different manufacturers' equipment, different applications and different protocols, it is necessary to support international standard network interfaces and protocols to provide a high degree of openness. The advanced nature mainly aims at the design idea, network structure, software and hardware facilities and selected technologies of the network system. Scalability means that the network system can adapt to the changes in demand. With the development of technology, the increase of information and the expansion of scale, the network will expand in scale and performance to a certain extent. The network requires high reliability, high stability and sufficient redundancy, and provides redundancy and backup of topology and equipment. Network security should be adopted in the construction of network system.
Control the security of the network through certain means to ensure the normal operation of the network. Manageability In order to ensure the normal operation of the network center, the network must be easy to manage, support the monitoring of network segments and ports, the statistics of network traffic and errors, and the location, diagnosis and repair of network faults.
Chapter IV Network Topology and Equipment Parameters
Construct physical topology and network topology according to enterprise requirements, and ensure their reliability, security and redundancy. Build a logical topology to ensure the feasibility of the topology. Select the equipment according to the topology and school requirements, and list the equipment parameters.
Chapter V IP Address Planning
Chapter VI Full Realization
Through the analysis of enterprise network requirements and topology structure, the feasible scheme is adopted to build the network, and the GNS simulator is used to simulate the network architecture, configure the equipment and list the configuration commands.
Chapter VII Network Testing
After the full realization of network requirements and the command configuration of topological devices, it is necessary to test the network performance of the whole network and a single device. For the whole network topology, it is necessary to test the connectivity of the network to ensure the smooth flow of the network. The redundancy test of the network can ensure the normal operation of the network when the equipment in the network fails.
Verb (abbreviation of verb) abstract
This design is aimed at the planning and design of campus network. For its network planning, we need to know the background and scale of the school first. After mastering the scale of the school, we can determine the specific functions of the network according to the needs of the school, and build the network topology and select the equipment with the lowest communication quality and cost.
After the whole network equipment is configured, it is necessary to test the network to ensure smooth traffic and normal access to external information. When a device fails, it can also ensure rapid diagnosis and normal operation of the whole network.
The above is the overall planning process of the campus network, and the specific implementation can be applied flexibly. According to the actual requirements, the selection and formulation of equipment and topology should also go through a lot of investigation and comparison, and select a set of the most suitable scheme to ensure the ideal effect of its design.
