Resilience Evaluations of a Wide-area Distributed System with a SDN-FIT system

A geographically wide-area distribution is a technique to improve fault tolerance of an information communication technology (ICI) application. Geographically wide-area distributed applications can be affected by network failure due to natural disasters and disasters by human error. Failure Injection Testing (FIT) is a method to verify and evaluate a fault tolerance of a geographically wide-area distributed application. In this paper, the authors propose a system that produces whole FIT scenarios for a wide-area distributed application. Exhaustive evaluations of fault tolerance can show how the scenarios can degrade the application. The authors also propose a probabilistically quantitative evaluation method from the aspect of topological constraint conditions.

I. Introduction

Because of the development of information communication technology (ICT) and with the widespread of electronic devices such as smartphones, people frequently use Information communication services. ¹
