Rising costs in healthcare, increased global competitions and rapid advances in networking and telecommunications promise to close the gaps between digital enterprising technologies and healthcare services delivery. Yet, end-to-end performance depends on applications, servers, and network relationships that are not always obvious. The research presented in this paper examines the requirements of E-health applications from a telecommunication point of view by studying end-to-end network performance within and between three hospitals in the CentralWest region of Ontario. First, a definition of traffic profiles and applications is established. Then, hospitals LANs are configured and simulated to support nominal and peak traffic loads.
