An Overview Resilience in Computer Networks and Network Topologies Using Different Metrics

Abstract

The physical infrastructure, as well as the protocols and applications that computer networks use to communicate, is increasingly convergent and distributed, which allows the generation of hybrid network configurations that use proprietary software with open-source solutions. Therefore, this physical infrastructure represented by connections between different nodes is exposed to fault tolerance or resilience or elastic computation, which means a continuous operation in the time and space determined with the minimum of failures between their links. In this paper, we present an analysis of resilience in computer networks considering the position of different authors. It also provides an idea about the utility offered by the metrics of resilience in network topologies from a series of metrics that make up network topologies, including direct and indirect links, node degrees, regularity, symmetry, diameter, diversity of routes, etc. In addition, a model based on resilience metrics is proposed that allows to be the use of empirical data and simulation. The main contribution of my proposal is the results obtained through experimentation that allow obtaining relevant information regarding the behavior of resilience in computer networks with different types of network topologies.
