Title
Modeling user-perceived service availability
Abstract
Service availability is an important consideration when carriers deploy new, packet-based services. In this paper we define the service availability based on user behavior, and derive formulas to compute service availability starting with the user behavior model and the system model. To automatically generate high fidelity user and system models, we use Stochastic Reward Nets (SRNs) and demonstrate how to combine the user SRN model and the system SRN model to analyze the service availability. We apply our approach to an SAF compliant media gateway controller (MGC) architecture in VoIP system. By building and numerically solving the combined SRN model of the MGC and the user, we compute the service availability, and evaluate various factors that influence it.
