The goal of any communication network is to support an end-to-end solution or business process. Resiliency of the system requires the resiliency of the end-to-end solution, not just the resiliency of the communication network component of the system. Analysis of network traffic can be used to improve the resiliency of the end-to-end solution that is running on the network. In this paper, we propose a solution for the end-to-end resiliency of IoT systems that we are building at IBM Research, and discuss the insights we have gained from this investigation. These insights should be applicable to a wide variety of solutions to monitor client resiliency.
