Dependability analysis of a commercial high-speed network

Abstract

This paper presents an injection-based approach to analyze dependability of high-speed networks using the Myrinet as a n example testbed. Instead of injecting faults related to network protocols, we injected faults into the host interface component, which performs the actual send and receive operations. The fault model used was a temporary single bit flip in an instruction executing o n the host interface's custom processor, corresponding to a transient fault in the processor itself. Results show that more than 25% of the injected faults resulted in interface failures. Furthermore, we observed fault propagation from a n interface to its host computer or to another interface to which it sent a message. These findings suggest that two important issues for high-speed networking in critical applications are protecting the host computer from errant or malicious interface components and implementing thorough message acceptance test mechanisms to prevent errant messages from propagating faults between interfaces.

Software-based adaptive and concurrent self-testing in programmable network interfaces

“…However, the majority of errors displayed a high degree of repeatability. Such repeatability has also been reported elsewhere [23].…”

Research on reliability evaluation of high-speed railway train control system based on fault injection

“…Fault Injection domestic research began in the mid eighties, Current research focused on under the high-end Fault-Tolerant Computer System, such as the on-board computer system, 1arge-scale weapons systems and aerospace systems, in developing the credibility of the 978-1-4244-7388-511 0/$26.00 C2010 mEE 288 evaluation of needs, software or hardware fiwlt injection system to verify the evaluation system features [5][6][7].…”

Design and Realization of Fault Injection Based on CTCS-3 Simulation

“…This technology is to inject trouble mode sample into system to evaluate system function design [1]. Software implemented fault injector (SWIFI) [2][3][4][5][6][7][8] is to simulate hardware or software failure by modify the content of memory or register based on some kind of fault model.…”
