The report is prepared for an IT institute for connecting the different floors of the campus building and prepare a scalable design of the network. The budget required for developing the network framework is estimated with the identification of the hardware that are required for the development of the network. The number of Pcs that should be installed in the labs and areas that should be covered for creating the network should be analysed for the development of the network. The needs of the current standards that should be followed for the network development is analysed and maintained throughout the development process for eliminating errors in the configuration of the network.
The main scope identified for the developing the network solution for the IT institute are listed below:
The network is designed for the development of the network solution for the It institute and connect the four classroom, library and the computer labs with each other for enabling transfer of data packets between the PCs connected in the network. The wireless access point is installed in the network for enabling the user to connect their handheld devices with the wireless access point. The area of coverage of the wireless signal should be analysed for deployment of the wireless access point. The network device are placed according to the structure of the building and the wireless access point is secured with the application of WPA PSK2 for limiting the access of the wireless access point to the illegal users to reach the different points of the network. The network is subnetted for reducing the wastage of the IP address and reducing the congestion of the network such that the efficiency of the network is improved. The configuration of the network is done in cisco packet tracer and the hardware that is used for the development of the network is given in the report for the estimation of the requirement of the project. The router is also configured with IP telephony such that the network supports the VOIP service and the cost of communication in the network can be reduced. Serial connection is used for interconnecting the two routers and enabling communication between the two floors of the network. A firewall is used connecting with the ISP router such that the unknown sources cannot be reached the internal network of the campus.

Conclusion
From the above report it can be concluded that with the identification of the current needs of the network solution the accuracy of the configuration can be improved and thus it reduces the risk of access of the network from any external agents. For the development of the campus network design the main focus is given on the security of the network and availability of the network for all the users. The network device that are used for the development of the network is selected based on the industry standards that is suitable for the IT institute. A simple IP addressing plan is used for the configuration of the network device and a local DHCP server is used for automatically assign the IP address to the network device connected with the library switch. Each of the classroom and the computer are labs are kept in separate vlan for increasing security and reducing collision of the data packet in the network. Wireless device are connected with each of the switch for allowing the user to connect their wireless device and increase the efficiency of the network.
