DEFINITION: A disruption-tolerant network (DTN) is a network designed so that temporary or intermittent communications problems, limitations and anomalies have the least possible adverse impact. There are several aspects to the effective design of a DTN, including: The use of fault-tolerant methods and technologies. The quality of graceful degradation under adverse conditions or extreme traffic loads. The  …

FAULT TOLERANT DEFINITION (continued): …  ability to prevent or quickly recover from electronic attacks. Ability to function with minimal latency even when routes are ill-defined or unreliable.Fault-tolerant systems are designed so that if a component fails or a network route becomes unusable, a backup component, procedure or route can immediately take its place without loss of service. At the software level, an interface allows the administrator to continuously monitor network traffic at multiple points and locate problems immediately. In hardware, fault tolerance is achieved by component and subsystem redundancy.Graceful degradation …
