Abstract

This paper presents a reliability and availability evaluation of a large network based education (NBE) system called NovaNET. NovaNET is a wide area NBE system which serves thousands of users on a daily basis. A successful NBE system is expected to provide appropriate Quality of Service (QoS) guarantees to its users. Among the most important extended QoS parameters are system reliability and availability. Ever since its inception NovaNET has been providing its users with daily reports on system reliability and availability during scheduled user hours of operation. We present results from a study of NovaNET using 9 years of operational reliability and failure data. The data are used to discuss practical bounds on reliability and availability of a viable and successful NBE system
