Sažetak
IT support will be provided through the administrative segment of the CHIS. The administrative segment would include hardware, software and personnel needed for governing and administration support to the CHIS as a whole. Hardware implies generic servers like mail, www, and DNS, data bases and specific application servers. Software implies appropriate business applications needed for every-day operations like administration, accounting, and procurement. Distinct care should be taken when purchasing or developing such applications. Standardized and widely adopted solutions that enable transparent implementation into broader information environments should be aimed. Required prerequisite for successful implementation of IT support is continued restructuring of the Croatian public healthcare system and comprehensive standardization of its business processes, and documentation. Technical preconditions include warranted belt widths and service quality parameters, QoS (Quality of Service), for directed real-time traffic course.The communication platform will include local computer networks, LAN (Local Area Network), connected into a unique intranet by use of widespread network, WAN (Wide Area Network), telecommunication service provider at the national level. In practice, LAN networks are merely a part of the communication infrastructure of the healthcare computer system. Logical division into the telemedicine and administrative segments, and other possible segments should be carried out by use of appropriate network functionalities at both LAN and WAN networks. The LAN segment architecture will be defined according to a particular case, always following the existing technical standards in the field of LAN network design. At the access level, quality L2 switches with additional functionalities for VLAN configurations (Virtual LAN) should be installed. At this level, the needs will be met by use of Fast Ethernet (IEEE 802.3u) technology. The distribution level will consist of L3 switches at which all advanced communication functionalities will be configurated, e.g., VLANs, ACL, QoS mechanisms, IP direction, etc. At this level, Fast Ethernet and Gigabit Ethernet (IEEE 802.3ab and IEEE 802.3z) technologies will be combined. Server computers will be located at this level of the LAN network. The axis of a particular LAN network will be accomplished if there is real need for it, and will be based on optic medium. An advanced solution would be Metro Ethernet concept with the use of Gigabit Ethernet (IEEE 802.3z) and DWDM (Dense Wavelength Division Multiplexing) technologies, depending on the distance and specific characteristics of particular locations. The use of such LAN axis is expected to be only required in large cities (Zagreb, Split, Rijeka, Osijek). A necessary redundancy should be ensured at the level of distribution and in LAN axis. The use of wireless LAN, WLAN (Wireless LAN) technology is possible within controlled areas of particular institutions and is acceptable for administrative purpose, whereas the use of cable media (UTP, optic fiber) should be preferred for transfer of information that may by its contents be critical for patient health and privacy. In order to reduce the cost of system construction, network resources of the telecommunication service provider at the national level will be used. In the initial stage of the system development, until the telecommunication activities reach a certain level of intensity and frequency, ISDN technology will be used in the video communication part of the telemedicine segment. Later in the course of the system development, ISDN will probably be used for video communication with distant international parties. The VPN concept accomplished by use of IP/MPLS (Internet Protocol/Multi Protocol Label Switching) technologies will ensure high flexibility and scalability of the overall health information system, and will to a certain extent warrant the users' traffic safety. In this terms, the VPN concept has been anticipated as a logical evolutional step. In addition, such a concept provides an opportunity for transparent accomplishment of extranet with relevant services other than healthcare and beyond the Croatian national territory. In this way, openness of the system is achieved, which is of utmost importance in the light of current globalization processes. The mobile elements of the telemedicine segment and health information system as a whole, such as emergency teams on field interventions, physicians at home or travel will need access to internal resources of the health information system. Such a remote access to the intranet can be provided by use of any of the access technologies available, including POTS (Plain Old Telephone Service), ISDN (Integrated Services Digital Network), ADSL (Asymmetric Digital Subscriber Line) and GPRS (General Packet Radio Service). Activities on the construction of national UMTS (Universal Mobile Telecommunications System) that opens rather real possibilities of audio visual information transmission, are under way. In this way, the mobile elements of the system will have access to relevant data and applications on the intranet at any moment. Analytical methods will be used to define the main traffic directions and required traffic parameters. Based on these parameters, the network architecture will be developed, the capacity determined, the QoS parameters created, the safety mechanisms implemented, etc.
