Healthcare Network Solution | Introduction

At the end of the 20th century, computers and the technologyfield overall began embracing the idea of being ‘open.’ With this, we saw the development of new interoperable platforms and the advent of more healthcare-focused technologies, such as the computerization of roentgenography, CT, and sonography scanning and x-ray communications tools. At the same time, centralized computer systems downsized and tools such as electronic medical charts began operating onstandard software such as Windows and UNIX. Meanwhile, with the explosive spread of the Internet, hospital networks began standardizing on IP (Internet Protocol) and shifting away from more conventional protocols, such as SNA. It has now become possible for individual hospitals to operate on a single IP network, as the systems have become more convenient and economical. However, as electronicmedical charts have become more commonplace, hospital operations have shifted to a paperless environment where all the information is managed as electronic data.This means if the network shuts down, all medical treatment stops. Furthermore, the network, which is set up across all corners of a hospital, is large-scale and increasingly complex.The global penetration of Windows, UNIX, and IP networkshas rendered them more inexpensive, but security issues are now more of a concern. In keeping with these developments in hospital network administration, this booklet explains important features about hospital network construction based on three key concepts: ‘Non-stop Network,’ ‘Secure and Reliable Network,’ and ‘Ease of Operation.’

Importance of the network
Today, hospitals generally conduct business with use of multiple integrated healthcare information systems. However, a network does not exist for each system; rather, it must be designed, constructed, and operated as a single, common infrastructure. Since a network system failure can lead directly to entire hospital routines and operations coming to a halt, a‘Non-stop Network’ is one of the most important components within hospital administration.

Meanwhile, as a result of the explosive spread of Internet in the latter half of the 1990’s, previously closed IP networks became more open and inexpensive.This has made the technology more readily available, but at the expense of exposing a variety of security vulnerabilities. As a result, hospital...
