The impact of failure management on the stability of communication networks
In this work we deal with communication networks in which links may fail. We propose an adversarial model for describing the traffic pattern occurring in this type of faulty systems and study properties concerning their stability, especially under (nontrivial) underloaded worse-case scenarios. We show that, depending on how the system is organized and prepared to deal with failures, the dynamics of the system change and thus the conditions for stability. We propose three different ways of failure management and study how they influence on the stability of faulty communication networks under the adversarial model proposed. We show that some failure managements can provoke the instability of even very simple networks.
The structure of GMA is introduced. Static displacement-force model and magnetism-machine coupling model for helping understand the magnetostriction and establishes simulation model are given. Simulation result shows that response time of machine part is slowness. It brings some disbennifit affection if minish damp. For example,exceed quantity and undulation will argument. It is important to ameliorate dynamic characteristic of the system to append a reasonable adjustor.
