Availability

View this topic in
In telecommunications and reliability theory, the term availability has the following meanings: The degree to which a system, subsystem, or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, i.e. , a random, time. Simply put, availability is the proportion of time a system is in a functioning condition. (Wikipedia.org)

This paper investigates the availability requirement for the fault management server in high-availability communication systems. This study shows that the availability of the fault management server does not need to be 99.999% in order to guarantee a 99.999% system availability, as long as the fail-safe ratio (the probability that the failure of the fault management server does not bring down ...

Because of the fast pace of information technology, an electronic product may be in the field for just a couple of years. Therefore, instantaneous availability and interval availability during its operational lifetime are more important metrics than the steady-state availability. The paper presents a stair-step approximation to the instantaneous availability and interval availability for systems with time-varying failure rates. The ...

  • Complex High Availability System Analysis

    This chapter applies many techniques we have explored in this chapter to a more complicated but practical system architecture frequently employed in the telecommunications industry. We consider a variety of techniques - including Markov analysis, Monte Carlo simulation, fault tree analysis, sensitivity analysis, and Matlab simulation. We see firsthand how state space explosion in Markov analysis can occur. Although with a variety of tools available, extracting information from the model is not difficult, understanding all of the possible interactions becomes increasingly difficult with state space explosion. We see that many of these interactions are either insignificant or nonexistence. By partitioning and/or simplifying the model, we lose little but gain valuable information on the system behavior and how we might improve it. We compare both the more complex models and the simplified models to show this. With the approach to solving complex analysis problems provided in this chapter, as well as the many other techniques for solving reliability problems and improving reliability explored in this text, the reliability analyst will be able to successfully tackle a wide variety of reliability analysis and design problems. These techniques applied optimally will help contribute to the improvement of the reliability of the systems and products the analyst encounters.
