Abstract

In this paper, a holistic approach to realize survivability of distributed information network systems for critical applications(DISCA) based on three basic states, processed, stored, and transmitted, of information (called a PST-based system model), is proposed and its evaluation method and some experiment results are given as an example of its application. A PST-based system model brings all three parts together and coordinates them through the services supported by them, in which whole system’s survivability is embodied by system services and their interdependency relations. With this model, a multi-layer survivability framework based on the information states is formed and the complexity of a DISCA system in implementation and evaluation can be conquered in the most prevalent approach—“divide and conquer” approach.
