IT College Network Design Project: Logical, Efficient And Scalable Network Design Essay.

In this project you are required to design a network for an IT College that has recently leased a building in Melbourne CBD with the aim of offering IT related courses to its students.

Upon initial planning, you have identified that there are 400 users in the college, 300 users in building 1 and 100 users in building 2. Every building has a spacious lobby for users which is 200 meters open space where wireless access is required. Only authorized users should have the access to this wireless network. Distance between these college buildings is 500 meters. A high speed internet connection is required which needs to be shared among the users. Selection of appropriate standards and technology for network implementation plays a vital role in this project.

Building 1 has four computer labs and building 2 has three computer labs. Each lab uses 35 computers. Each lab will also have a server in the closet located inside the lab. IP phones are located in each lab to communicate to service desk. The IT Institute also wants to setup four classrooms, each containing one computer which requires internet connectivity.

Your task is to come up with a logical, efficient and scalable network design that will be suitable for this institute. The institute has allowed an adequate budget to purchase any networking devices that may be required, yet obviously does not want to spend more than necessary. In addition, industry-specific standards must be used and apply to IT infrastructure and services.

Write a report and include:

1. Build a document giving all the necessary network designs (enough information should be provided that will allow any technician to build your network structure from scratch).

2. Simple IP addressing solution (step by step workout of the calculations) that leaves room for growth, is easy to administer and has the minimum wastage of available IP address space.

3. Write configurations of each networking device which are included in the network.

4. Configure two switches and two PCs on physical networking devices and demonstrate the working model.

The scope of development of then network solution identified are listed below:

• The area that should be covered by the network and the number of users connected with the network should be identified for the development of the subnet plan
• The types of cables used for the interconnection of the network device should be managed
• A network diagram should be prepared with all the details of the network and each of the department should be assigned with separate VLAN
• The voice and the data channel should be separated for increasing the efficiency of the network and reduce congestion
• The subnet plan should be created with keeping extra IP address such that the network can support the growth of the college
• A prototype of the network should be configured for the identification of the error and resolve it for increasing the efficiency of the network.

The network design is created following the requirement of the IT college where the college needs to connect its 400 number of users of different departments. For the development of the network solution a subnet plan is prepared and separate switches are used for each of the Labs. The switches are configured with VLAN such that congestion is avoided and the communication cost is reduced. The building and 2 router are configured with IP telephony for reducing the communication cost between the departments and the Labs and each of the routers are connected using the serial cable. A wireless router is connected with the core switch of the building for increasing the scalability of the network and enabling the user to connect their wireless device in the network. The development of the detailed network diagram helps in identification of the hardware needed for the development of the network framework.  The router needs to be configured with access control list such that the unknown packets cannot reach the servers connected in the network and the network is secured from the external agents. The development of then network also helps to identify the type of cable and the ports used for interconnecting the network devices.

Major Network: 10.10.30.0/24

Available IP addresses in major network: 510

Number of IP addresses needed: 253

Available IP addresses in allocated subnets: 442

About 91% of available major network address space is used

About 57% of subnetted network address space is used
