NAPA: An algorithm to auto-tune unicast reliable communications over DDS

Abstract

This paper proposes NAPA (Non-supervised Adaptative Publication Algorithm) a framework for a uto-tuning unicast reliable communications over DDS. We provide the NAPA design rationale, and some implementation details. After the experimental conducted evaluation, we demonstrate how using the subscriber's feedback, as NAPA does, the publisher can vary its sending rate in order to improve the overall performance in terms of end-to-end latency and throughput in DDS applications.
