Distributed processing has provided a number of advantages to network designers. These service advantages include better performance, backup and availability potential. This paper uses simulation to predict network performance of three host models: single host, dual hosts and dual hosts with mirrored file systems. The results indicate that the dual models(More)
Healthcare organizations face rising costs in effective management of hospital information systems. Adding to this burden is the Joint Commission’s mandate for disaster preparedness, which demands restoring access to information after unexpected catastrophes. Disaster recovery within healthcare organizations is essential because of its inherent critical(More)
The paper was designed to determine the effect that nesting Ethernet switches had on round trip delay of packets sent from a client to a server and back. A test bed of switches nested seven layers deep was used to collect data. Four experiments were run using both single client server pairs and four simultaneous client server sessions following the same(More)
The advent of distributed processing and global information systems has driven the need for fast, efficient and secure global authentication systems. Typically distributed processing implies that any given application will require computing resources from multiple computing nodes, and hence for the sake of convenience will require single sign-on capability(More)
