Robustness metrics for optical networks

Abstract

Telecommunication networks are vulnerable towards single or simultaneous nodes/links failures, which may lead to the disruption of network areas. The failures may cause performance degradation, reduced quality of services, reduced nodes/links survivability, stability, and reliability. Therefore, it is important to measure and enhance the network robustness, via the use of robustness metrics. This paper gives an overview of several robustness metrics that are commonly used for optical networks, from the structural, centrality and functional perspectives.

Application of the Jaya algorithm to solve the optimal reliability allocation for reduction oxygen supply system of a spacecraft

“…One of the first researchers to take up the reduction oxygen supply system (ROSS) study of a spacecraft system for the first time by Aggarwal [1], and due to the importance of the topic in terms of engineering and science, light was re-shed by several researchers such as Hassan et al [2]- [9] where the researchers discussed the reliability of this system and the study of mean time to failure (MTTF) using the engineering properties of many reliability limits. Also Abed et al [10] discussed the issue of optimizing the reliability of this system has solved by using a genetic algorithm.…”
