14.1 Fundamentals of Network Reliability

A computer network finds widespread applications in multiple fields. One of the major criteria to determine whether a network system can be used for a certain purpose is the reliability of the system. It is essential to understand what reliability means for a network system, the idea behind various concepts related to it, and the different methods that can be adopted to calculate the reliability of various systems. Today, computer systems and networking have become the backbone of society. No matter if the field of application be big or small, networking and computer systems have found their way into each one of them. New technologies are being proposed and developed at a rapid pace, each with its own set of characteristics [1]. But for the new technologies to supersede the previous ones, it is important for them to be better off than previous technologies in terms of some ...
