According to the requirement IgnaceBazigaHospital owns a 5-story building and houses many departments that span multiple floors. Its Radiology department is spread across the first and second floors, connected by a dedicated LAN. The department has recently deployed a new “Radiology Images” application as part of their initiative to digitize patient records. However, the department staff sometimes faces long application delays during busy hours. It also experiences regular delays in Internet connectivity, FTPS services, web services, and email services. As per the case study, we have to build a prototype of a network that will support a medium-size network for 200 to 1000 devices. It will provides high speed and good quality of the service for the organization. To build the strong network, I am using a good quality and good feature network devices like router, switch etc. Computer user system should be free from a virus so we might be used antivirus tool. Another idea from my side, we should use IDS system which is a helping to provide the security and help to identify the internal and external attacker. A network should be reliable so that in future we can be easily modified and enhance the system as the company requirement and user demand without disturbing existing network and we can also increase the scalability of the system.
Router: Routers is another significant part of the network and it helps to link various network to each other. There is a different type of network topology available in the network architecture. A router is a very valuable part because it helps to data communication by using a method of packet switching. Routers help to reduce the collision in the network. Routers are also helped to decrease the traffic in the network.
Laptop: It is a host of the network
Switch: A switch also helps to avoid the collision of the network. Switches are also helped to connect the different workstation with each other.
Desktop PC: It is also a host of the network
File Server: It is a server which is a help to transfer a file from source to destination

Security configuration helps the administrator to control and monitor the system and fulfill all the objects of the network.
To maintain the quality of service, we have to maintain time to time network configuration and for better security use the network security tool. We have to create the protocol of the network according to human factor means all the user can access a network with reliable and get the secure and good bandwidth [4]. Time to time update the devices of the network and keep data security and the backup. Give the proper IP address so then there should not be any conflict in the network.

As per the case study in this project network has to be designed such that it should be flexible and reliable, it must also be secure and data need to be protected from outside attackers. To maintain the quality of the network, it must be using best network devices such as routers, switches available in the market, we will analyze the requirement and design the network. Before designing the network in the packet tracer and simulating we need to add sufficient modularity, resiliency, and flexibility into the design

In this project the network is designed for IgnaceBaziga Hospital that owns a 5-story building and houses many departments that span multiple floors. Its Radiology department is spread across the first and second floors, connected by a dedicated LAN. We have used class A IP address so that it can have at least 1000+ devices connected through the network. The human factors are studied and used in the network so that the network is reliable, secure and flexible for future development of the network. The routers and switches are most important network devices that need to configured and optimized in a proper way. The simulation of the network is done in Packet tracer and network is optimized and tested .
