The OSI model implies the Open Systems Interconnection model that contains seven layers. These seven layers are required in order to send a piece of information from one system to another across a network, and so these layers form an important part of functioning of the hospital and the communication of the different departments. Taking the given data into consideration, the analysis of the overall framework of the network connections in the hospital is conducted. The formation of the network shall first be analyzed keeping in mind the working of the hospital. The entire hospital is connected through the Ethernet connection.
The network has a tree topological connection and so the Ethernet has a centralized connection. The different branches of the hospital are connected to each other through this Ethernet cable. On one hand where the administrative branches are connected by a 1000 BaseT using a CAT cable, the clinical functions are done through the 1000 BaseF connectivity fiber cable Ethernet. There is a difference between these two Ethernet connections probably because of the difference in the work load and also the nature of work in the clinical and the administrative sections.
The physical layer of the OSI model governs the type of internet cable to be used for such connections (Surhone, 2009). The two Ethernet cables are connected to each other through the network bridge, and so the network bridge is used as a connection between the two departments. The type of hardware that would be involved in the transmission of data that includes not just the computer systems or the topology involved but also the cables and the other switches and the coolant and ventilation used are the issues that are governed by the Physical Layer.
Since the messages get transmitted in an encrypted form and Health Insurance Portability and Accountability Act (HIPAA) is being strictly adhered to, the role of the Presentation layer comes into picture. The presentation layer has the responsibility of encrypting the entire data using the desired algorithm (Advanced Encryption Standard) in this case. The protocols like the TLS and SSL are used so that the data travels through an encrypted traffic and the security is also enabled. Since, HIPPA is applied in the Hospital, it is important to keep the data of every patient private.
Hence, the data of every person is kept in the encrypted format so that the information of the patients can be kept secrets and health of the patients may not be viewed by any other person without the prior concern of the concerning patient who owns that data. This is taken care of by the IT and Data Center section and the Human Resources. Those sections that transfer their data to these sections are also responsible for transferring their data to these sections in a secure manner.
