The modern educational system, in one way or another, aims to train students’ ability to work with information. It is no coincidence that the prior areas of development of education pay big attention to information processing skills, which later will become the pillar of the professional activity of graduates in the information society, a necessary component of information culture In such circumstances, students will acquire the knowledge necessary to express themselves creatively, learn how to evaluate the accuracy of information, develop critical thinking and distinguish information and knowledge. Local networks are common in the field of education. The majority of schools and education institutes have PCs linked to a LAN network. At the same time, modern technologies allow you to connect computers that are located in multiple continents, and not just in the same room or building. Many educational institutes have branches in multiple countries, with PCs connecting to local area networks. In addition, local networks can connect computers from different colleges or universities.
Through the Internet, each student can get public access to educational materials that can be given in the shape of simple textbooks (e-text), as well as complex interactive systems, computer models of virtual learning environments, etc. The number of users and sources of information on the Internet is continuously increasing. Furthermore, there is a constant quality in the improvement of telecommunication services. Because of this, not only companies and organizations operating in the economic sector and other fields have high-quality access to the Internet, but also educational institutions.
Many systems are prone to a number of risks that can take full control of crucial resources (e-mail systems, network equipment management and others). Crucial risks are usually come because of the uses of out-to-date versions of applications and operating system. Studies have shown that modern business networks are rather vulnerable to attacks by internal and external intruders. The ability to access the critical resources of most of the systems examined leads to the conclusion on the need to improve information security measures, in particular in the field of password policies, web application protection, periodic security updates and protection of privileged account. For early detection of security deficiencies, the system administrator must regularly perform, security analyzes, including penetration tests. (2018). Campus Area Networks (CAN).

Project proposal overview:
Campus Area Network (CAN) is a computer network that provides wireless Internet or LAN access for users located in two or more buildings in the limited geographic area, or in the open space surrounding these buildings. The area University network is usually regulated on the campus of a university or a university {Look at the Diagram A} but the same type of design and design can be applied for other purposes, for enterprises, office buildings, military bases, and complexes. Public places like supermarkets, entertainment centres, etc. Another form of the thunderstorm can exist during some special events such as rallies, music festivals. The area network of the elementary campus can also arise spontaneously, due to the extension distance the radio signals of the access points, which are not limited by the walls of the buildings. It also makes sense to have additional access points for larger and more complex CANs, located in specially chosen places to cater to customers. (2018). Campus Area Networks (CAN).

Network goals description:
Oman International University’s network as it launches on its early stage and while the University’s budget is not sufficient, it is reasonably consists of four branches in Bahrain, Qatar and Kuwait besides the main campus, which is located in Sultanate of Oman.
On the other hand, The University’s network must be complete, including information about the campus’s administrative office and other integrated systems of business information management for most teachers and students to provide a network environment for teaching and Advanced Search platform work.
The campus network covers the entire campus, and network design follows the following basic principles of ?ve:
Reliability and high-performance networks must be reliable, including network-level reliability such as routing, switching aggregation, redundant coupling and load balancing. The network must have a Su?cient performance to meet the needs of the business.
System scalability and scalability to be scalable and scalable, with business growth and application level, the data network and information flow will grow exponentially, the need for good network scalability, and can continue Improve with the development of technology. The equipment must be used in accordance with international standards of systems and products to ensure that the system has a long vitality and scalability to meet the future requirements of the system upgrade.
Easy management, easy maintenance as the campus’s backbone network system is large, rich and complex usage, network management system need has good manageability, network management system with control, error detection and Isolation, filter settings and other functions to facilitate the management of the system and maintain. At the same time, as much as possible to choose a high level of integration, the module can be a common product for easy management and maintenance. Here we use the equipment are Cisco switch, ?rewalls.

Security, the confidentiality of the network system must have good security. As the backbone campus for multiple Intranet users to provide interconnection and support to a variety of companies that require flexible and effective security control, but also must support the virtual private network to provide the security of various options of levels. In the design of the system, not only consider the full exchange of informative resources, but also pay attention to the protection and isolation of information, so that the system should be different for different applications and the environment of various network communications, take several di?erent measures, including system security mechanisms, access to the control authority data. To the secondary construction of the campus network, can through subnets and VLAN switches to achieve network security.
Using structured shapes and modular design with ? and complete, to meet the system and di?erent reference needs of users to adapt to changing needs. Meet the goals and functions of the system as a goal, to ensure that the overall design of the program is reasonable to meet the needs of users while maintaining the use of system maintenance as well as the future system of Secondary development and transplantation.

Chapter Two
Literature study

The best appropriate methodology that we are going to use for Literature study is through applying a survey of campus issues. published a survey study done by the National Research and Education Networks (NREN) of the some interesting issues on CAN networks, the results shows as fallows.

Low bandwidth to the NREN:
In the survey, the available bandwidth between the institutions and their NRENs shows a very broad spectrum, ranging from 2 MB/s to 10 GB/s. These figures are not easy to interpret. The low bandwidth can often be suitable for small institutions with few end users. However, a significant number of medium-sized institutions also have a low bandwidth for their NRENs; It seems that this is mainly two to its obligation to use an intermediate network to connect with the NRENs.
In an attempt to make meaningful Cross-institutional, the average bandwidth available to the computer has been calculated. The results range from 8 KB/s to 100 MB/s for the equipment. This has a large bandwidth difference, and it is not easy to explain how an institution that provides 10-50 KB/s for computers can cope with this situation. It is not possible to draw clear conclusions from the survey, but it is clear that end users with a reduced bandwidth cannot take advantage of the full range of network services.

Satisfaction with low-bandwidth:
Connections of the institutions that participated in the survey, 25% reported that they had a relatively low bandwidth between their campuses and the NRESs, i.e. less than 34 MB/s. Some of them were small institutions with few students, but some were not, with more than 5,000 students enrolled. One would expect that larger institutions would be less content with the bandwidth available to their user community. Surprisingly, however, 81% of respondents felt that the bandwidth for the NRENs per user was sufficient.
It is likely that many end users, particularly those of Class A, do not directly access external services, but through proxy servers, cache servers, central mail servers, and so on. This way you can cope, many thousands of Class A users in low-bandwidth connections. However, it is very important to properly manage these servers.
It was not able to investigate more deeply because these institutions seem to be satisfied with their low bandwidth. This can be an important object for further studies. One possible explanation is that the expectations of the user community in these institutions are unusually low and that these users are only content with basic network services.

High bandwidth at NRENs but little use of network services:

The serious reporting of campus subjects, the serious study of researchers ‘ investigations and the latest edition of the annual Compendium of national Research and L networks for Educating in Europe indicates that the low-bandwidth problems identified in the serene study are now resolved to a large extent. Today, many institutions have adequate bandwidth (or better than the right one) to meet the current needs of their user communities. The phenomenon of network bottlenecks – on both campus and elsewhere – is now rare.

Performance of the main campus network:
In general, there have been great improvements over the last few years in campus network infrastructure. However, there are still isolated pockets where there is adequate bandwidth; this may be for a number of reasons, including obsolete equipment, construction problems, fragmented institutional management, geographic remoteness, and lack of funding for networking.

Progressing to improvements:
The survey shows that the institutions are offloading Gigabit networks on their campuses. However, their availability is limited. About 5% of the institutions can provide 90% of its end users with a Gigabit connection. This will not be a major problem for most users in Class A. However, there will be serious repercussions if this distribution is uniform and only 5% of class B and class C users have access to Gigabit networks.
One of the recommendations in {Table 1} indicates that a high percentage of new end-point equipment must provide Gigabit serial connections. There may be a slight additional cost to purchase these switches today, but labor costs for installation and their management will be similar to those of lower grade equipment, and investment will now be depreciated later as the DEM Increases is more bandwidth. It is also strongly recommended that institutions with an obsolete wiring plan be reinstated as soon as possible.

Network backbone performance on campus
In general, there have been great improvements over the last few years in campus network infrastructure. However, there are still isolated pockets where there is adequate bandwidth; this may be for a number of reasons, including obsolete equipment, construction problems, fragmented institutional management, geographic remoteness, and lack of funding for networking.

Inter-Campus connectivity within institutions responses
To the survey, indicate that some institutions have difficulty connecting remote campuses. Interconnection links seem to work at unacceptable data rates. The survey shows that only 25% of the response institutions have an internal connectivity of more than 1.2 GB/s, while 35% of the institutions participating in the survey have connectivity to their NRENs of more than 1.2 GB/s. There may be several reasons for this Disparity in connection speed. It could be that there is a big difference in the size of the different campuses and that the smaller ones deserve lower connectivity rates. It could also be that the growth rate of external connectivity has exceeded that of the internal network. Another reason for the low-bandwidth between campuses might be the obligation to use regional networks in cases where remote campuses are a certain distance from the main site. It is also possible that the costs of telecommunications for better connectivity are prohibitively expensive.

Storage Devices:
Storage devices are one of the main components of any computer device. Virtually store all the data and applications on a computer, except for the hardware firmware. They are available in different formats depending on the type of device below. For example, a standard computer has several storage devices that include RAM, cache, and hard drive, as well as having possibly optical drives and externally connected USB drives.
There are two different types of storage devices:
Primary storage devices, typically smaller, are designed to temporarily maintain data and are internal to the computer. They have the fastest data access speed, and include RAM memory and cache.
Secondary storage devices typically have a large storage capacity and store the data permanently. They can be internal or external to the computer, and include hard drives, optical disk drives and USB storage devices. (2018). What is a Storage Device? – Definition from Techopedia. online Available at: Accessed 22 May 2018.

Network-Attached storage (NAS)
Network-Attached storage (NAS) is a kind of dedicated file memory device that gives local space Network (LAN) nodes with file based shared storage on a regular LAN connecting.
NAS devices, that do not commonly have a keyboard or displaying, are configured and managed with a browser-based utility. Every NAS resides on the local area network as a separate network node and has its own information processing address.
A major advantage of NAS is its ability to supply multiple users over the network with access to identical files. Before NAS, corporations generally had a whole bunch or maybe thousands of distinct file servers that had to be configured and maintained individually. Today, once additional storage capability is required; NAS devices will merely be equipped with larger disks or clusters to give scaling and scaling. Several NAS vendors work with cloud storage suppliers to supply customers with an extra level of redundancy for file backup.

CISCO Access Points
Wireless access points (APS or WAP) are network devices that enable wireless Wi-Fi devices to link to a wired network. They create wireless local area network networks (WLANs). An access point acts as a central transmitter and wireless radio wave receiver. The most stream of APS supports Wi-Fi and is most typically utilized in households, to support public web hotspots and in business networks to accommodate the proliferation of wireless mobile devices currently in use. The access point may be embedded within the wired router or it can be a standalone device.
