Abstract

The National Board of Medical Examiners (NBME) is a non-profit, independent organization which, since 1915, has prepared and administered qualifying test examinations that have been accepted by the legal agencies governing the practice of medicine within each state as sufficient proof of a candidate's depth of medical knowledge. The Federation of State Medical Boards of the United States (FSMB), Inc. is a non-profit organization that was founded in 1912. Its membership is comprised of the medical licensing boards of all the states, the District of Columbia, Guam, Puerto Rico, and the Virgin Islands. The United States Medical Licensing Examination (USMLE), which began in 1992 and is administered by both the NBME and the FSMB, provides a common evaluation system for all candidates for medical licensure. The USMLE is a single examination with three steps that together assess a physician's ability to apply knowledge important for effective patient care. The results of the USMLE are reported to medical licensing authorities for use in granting physicians the initial license to practice medicine in the United States, Guam, Puerto Rico, and the Virgin Islands.

The NBME and the FSMB are connected by a leased line link this link allows both organizations to exchange data and share databases of information relevant to the medical licensure process. In order to accommodate current and future information needs, a scalable, expandable, and secure network infrastructure was required. The network architecture that resulted supported document imaging, multimedia, client/server applications, and interconnections from other networks. Using the FDDI and Ethernet protocols coupled with switching technology, over a structured cable system, a network was created facilitating access to network resources of all interconnected computing platforms from any point within the network. The dissertation designing the Intelligent Network: An Architectural Model for the Enterprise Information System chronicles the design and installation of a switched virtual network infrastructure. Using multiple media access protocols concurrently, a network was created which supported 250 workstations, 15 PC based file servers, 3 V AX systems, asynchronous connections, and a direct connection to the Internet, with less than 5% of the total network capacity utilized.
