Tools for Application Performance Measurement

Surya Chataut, Stan McClellan, Jill Gemmill, (Proceedings of the Society for Design and Process Science June 2000).

Electronic commerce, Internet-based sales/marketing, and the corresponding need for corporations to re-engineer in order to rapidly deliver goods and services are shifting the dependence of the modern enterprise onto increasingly distributed applications.  As a result, the end-to-end management of these applications has evolved from the realm of "simple capacity planning" to the realm of "mission critical business functions".  It has become essential for successful enterprises to monitor the performance of such critical applications, from end-to-end, and from business function to business function. Thus, the terminology and technology of "Application Performance Measurement" (APM) has been tapped by industry analysts to become a multi-billion-dollar market in the next 5 years. The purpose of this paper is to present some representative technologies available in the emerging field of network performance. Along with a brief comparison so some APM products, we include results from specific tests and discuss their interpretations.

   With the advent of the "next generation Internet" and various related technologies, we observe important trade-offs between emerging network capabilities and design related application requirements for network-based distributed healthcare systems.  One of the aspects of these emerging network capabilities is Quality of Service, or QoS.  QoS guarantees are a necessary characteristic of "next generation" networks which will have a profound impact on the deployment of advanced, network-sensitive medical applications. In this paper we discuss some of the underlying aspects of QoS technologies and possible considerations in designing network-based medical systems.

Issues and Techniques in Network-Based Distributed Healthcare: Advanced Network Technology

Stan McClellan, Gary Grimes, UAB; Ken Burst, BellSouth
(Proceedings of IDPT'99, July 1-5 1999)

With the advent of the "next generation Internet" and various related technologies, we observe important trade-offs between emerging network capabilities and design related application requirements for network-based distributed healthcare systems.  One of the aspects of these emerging network capabilities is packet switched routing. Packet switch routing is a particular aspect of  "next generation" network structure which will have a profound impact on the deployment of advanced, network-sensitive medical applications. Here we explore some of the underlying aspects of packet-switch routing technologies along with inherent capabilities and constraints which should be considered when designing network-based systems.
