Edge Transport (ETRA): Edge Transport Protocol Architecture for Next Generation Mobile IoT Systems

Next generation mobile IoT systems such as autonomous vehicles, mobile robotic and drone systems demand new ways to integrate programmable edge compute and networking resources to manage and control them in real time. Current solutions to support real-time information delivery and sharing, handling mobility, multicasting and service migration need to evolve. In this paper, we look at the unique features of these IoT systems that take advantage of high bandwidth wireless communications and edge computing. To address these challenges, we examine the capabilities needed in a new transport architecture for edge networks (ETRA) to handle low latency (and high bandwidth) real-time data streams from mobile IoT systems that also require services to handle mobility, service migration, data replication and reliability. We exemplify ETRA's functionality considering the case for augmented vehicular reality, wherein autonomous vehicles share their sensors' point clouds with each other over a managed edge infrastructure.
