Network Requirement Analysis And Plan

Project Scope

The scope of the project is to provide a wireless connectivity throughout the Calasanz School to enable following features:

Internet access

Data and information sharing

Improved learning capability

Remote access to documents and resources for students as well as teachers.

The aim of this project is to provide a wireless network for the school. The wireless network needs to be scalable and secure. It should ensure data transmission efficiency with improved reliability. Furthermore, the project will also ensure that the network must not succumb due to traffic congestion and must keep out malicious intruders.

Challenges

Some of the challenges that the school face and needs to be addressed are:

Lack of reliable and secure networking

Lack of centralization of resources

Scalability issues.

User Centric Design Concept and Logic Design

Rationale

As already stated, the basic objectives of the respective LAN design is the integration of the efficiency, functionality, scalability, adaptability, and manageability. Moreover, the elements of cost efficiency and the effectiveness are also considered greatly when opting for certain devices and components such as the wiring options, hubs, and switching choices.

The devices used for the designing of the LAN are also readily available, easy to deploy, convenient to configure and inexpensive to be used at the larger scale, in case the LAN is to be enhanced in the future. The later factor will also be true for the Hybrid topology, i.e. the enhancement of the LAN in the future. Furthermore, it has already been stated that how the respective LAN design offer considerable extent of the reliability, sharing options, robustness, troubleshooting, debugging, management, etc.

Recommendation

Critically analyzing the LAN design, it is observable that following weaknesses exist, such as in case any fault occurs in the main bus topology line, it can halt the entire associated start LAN. Therefore, in the proposed solution, the respective weakness has to be addressed. Enhancing the available resources, the respective objective can be achieved by granting the exclusive as well as dependent autonomy to each of the star topology associated by the bus topology connection. In this way, in case of a failure of connectivity with the central server, the start server can act as an exclusive and independent LAN sub-unit.

Required Hardware

Following are the enlisted specifications of the devices to be purchased for the deployment of the LAN design:

1841 model Router is purchased;

Generic – PT hubs and the servers are purchased;

Hub 3Com Dual having 8 auto sensing ports10/100 Mbps was obtained;

2950 – 24 switches are obtained;

The PC’s and the Printers are also of Generic – PT type.

As per the price details provided by the online Cisco dealer and with respect to the number of devices deployed, following cost were spent over the respective LAN design:

Switches 2950 – 24 => $1048 x 6 = $6288

Hub 3Com=> $67 x 4 = $536

1000 ft Cat 5 100mHz PVC 4 – pair solid UTP => $33

4’’ Patch Cable => $5 x 7 = $35

Network Devices

Network devices can include a wide range of the devices such as the printers, PC’s, etc. Analysts also describe the network devices as the communication devices involving the deployment of the connection devise such as the switches, routers, hubs and the gateways. These devices are more likely to be associated with the Physical and the Data Link layers of the OSI model.
