A resilient application-level failure detection system for distributed computing environments
B. Welch, Sumi Helal, Ramez A. Elmasri · 2002
A methodology for detecting failures that occur in distributed computer systems connected by a communications network is described. The methodology utilizes active polling of monitored systems. The entities polled must be service entities that function at the application layers of service providing machines. A prototype system has been implemented to test this methodology.
