The hospital’s backbone network structure for the entire hospital is 1000Base T. Some of the other individual sections of the departmental network use different standards such as 1000Base F. The areas that use the 1000Base T are responsible for the administrative side of things. These areas are: hospital executive management, human resources, operations, facilities, finance, and IT data center. The areas that use the 1000Base F are responsible for the clinical areas. They include: radiology, operating rooms, wards, ICU’s, emergency rooms, labs, and pharmacy. For a failsafe, the entire hospital has a complete power backup system that automatically cuts over to a large diesel motor generator set.
The hospital uses a network bridge to interconnect its logical network. A network bridge connects multiple network segments at the data link layer, which is Layer 2 of the OSI model. The Data Link Layer enables data to be transferred between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. The hospital’s network is an Ethernet network. The Ethernet network uses a protocol called CSMA/CD which stands for Carrier Sense, Multiple Access with Collision Detection. The computers that use 1000Base T are networked with Cat. 6 cable. This cable allows for backward compatibility with the Cat. 5 and Cat. 3 cable standards but offers an increase in performance of up to 250 MHZ. The computers that use the 1000Base F are
