BUSINESS CASE: The Hospital information system has been in use to improve Hospital Networks efforts to become more competitive.

Main Parameters of the Hospital system :

There are three buildings in three different cities

Hospital Building in City 1: 150 Patients Room, and 25 offices (Main Building has the all Databases)

Hospital Building in City 2: 95 Patients Room, and 15 offices

Hospital Building in City 3: 80 Patients room, and 30 offices

All buildings have their own IT Datacenter.

IT system Hardware: Personal PCs, Server, Cables, Memory, Printer, X-ray, Big screen monitors, card readers, Scanners

IT system Software: MS Office, Financial /Accounting,

IT system Databases: Database for Patients, Database for Doctors, Database for Building, Database for Employees

IT system Network: Internet and Dedicated data communication lines between all four Buildings.

Dedicated data communication lines between all Buildings are private fiber-optic communication lines

Supplier Companies: Blood Test Lab, Bank, Medical Equipment Supplier, Medication Supplier.

QUESTION 1: You were given the following LAN in one of the hospitals . You should list the device and TCP/IP layer(s) that have been in used in each device on this network

You would write the name of the device and the TCP/IP layer(s)layer in that device ( Client Computer, Server, Switch, and router ).

QUESTION 2: Develop a network diagram illustrating the hospital IT network's key elements, including the following two different connection types.

a) Each Building has Internet communication from the local Internet service provider (ISP) . So it will communicate with local supplier companies and local patients

b) There is a dedicated data communication lines (fiber) among all three Buildings to prove access to all databases from each hospital.

This private connection is not open to the public to use.

QUESTION 3:

The hospital IT system has dedicated Fiber data communication lines among all three Buildings. On Monday morning, one of the fiber optic cables was damaged by a construction company. Telcom Company informed the Hospital that, it will take a week to repair the fiber cables. But the Hospital cannot wait one week to do business-to-busses transactions among all three Buildings. No fiber communication for one week is a big problem.

What would be your solution for this network connection problem?
