Abstract—Information networks are an important social infrastructure, and we should ensure their stable and sustainable operation. Since retry traffic greatly impacts network stability, we should, in particular, consider retry traffic when designing and controlling communication network systems. We previously proposed a hierarchical method that uses the quasi-static approach to evaluate system performance in the presence of retry traffic. This approach is based on the fact that system response times are much shorter than the users’ perceivable time-scales. For the sake of simplicity, previous work considered a specific model that assumed that all users’ behaviors were synchronized with respect to a certain time interval even though users behave independently. This paper introduces a performance evaluation method, based on the framework of the quasi-static approach, for networks in which retry traffic is generated by users autonomously.
