AN HOMOGENEOUS MEDICAL TELE-WORKING DOMAIN SUPPORTED BY A NEW REMOTE EXPERT CONSULTATION CONFERENCING SERVICE

This paper proposes a new multimode communication service, denoted as Remote Expert Consultation Service (REC-Service) which determines the way group teleworking is realized among distributed entities (workstat ions, data bases, etc) during a conference for medical diagnosis. The REC-Service organizes the involved operations into five different type s, called Conferencing Modes (CM). where each CM yields a traffic with variable attributes and requires of the network a special quality of service. Moreover, the structure of a Broadband user-Network Interface Unit (BNIU) is defined. BNIU statistically multiplexes the traffic of the entities working in different CMs into an Integrated Broadband Co mmunication (IBC) network. The maximum number of entities served per B NIU and the bandwidth usability have been calculated for several opera ting modes by modelling the BNIU as a queueing system and by applying special quality criteria, delay demands and traffic assumptions.
