Availability Modeling for a Networking Device using MEADEP

Availability and reliability are major concerns for networking devices. This Application Note describes an example of such modeling with the MEADEP Tool. The example model addresses not only device reliability but also software failures and integration of capacity with availability in a single model.

Availability Analysis of a Large Web Site

Availability is one of the most important attributes of online information systems – such as in e-commerce, ERP, and medical information. This application note describes the use of MEADEP for predicting the reliability and availability of an example large three-tiered e-commerce site. We also demonstrate how the results can be translated into business terms.

Modeling Operational Availability using MEADEP

Operational Availability is the actual availability of a system under logistics constraints including technician, travel time, sparing level, and restocking time. It is often the most important measure of availability for users who utilize the system in an environment of constrained resources. This Application note describes the use of MEADEP to model Operational Availability.

Using the Weibull Distribution in MEADEP

Weibull distribution is used where a non-constant (typically increasing) failure rate has been observed. The application note describes the use of the Weibull distribution in creating MEADEP models.
