This work proposes enhanced hybrid frame work for reliability analysis for Safety Critical Network Infrastructure. The proposed frame work enables design and development of web service for the safety critical systems to identify the component failures in the network infrastructure. The enhanced hybrid frame work of reliability analysis for multilayer in Safety Critical Network Infrastructure results in accuracy of identifying the failure of the component, failure modes of the component that makes the system more reliable and reduces the error rate in the network infrastructure. The Safety Critical Network Infrastructure requires a monitoring mechanism that can be used for public sector enables to detect failures as early as possible in the layers of the network. In order to work as a service provider for the critical components to the user a web service was designed and these failure results are used as database for efficient utilization of the data. © 2006-2015 Asian Research Publishing Network (ARPN).
