Strategies for Assuring Low Latency, Scalability and Interoperability in Edge Computing and TSN Networks for Critical IIoT Services

Abstract

In recent years, there has been an exponential growth of IoT (Internet of Things) devices in the market and increasingly, they are being part of critical mission functionalities for many industries. For this reason, processes associated with these devices are generating new requirements at the level of interconnectivity, security, and scalability. Due to the large volume of devices, this growth process has tested the existing communications infrastructure, deployment architecture, different support services, technical requirements and the intrinsic characteristics of the services offered. In this sense, the use of Edge Computing schemes and TSN networks (Time Sensitive Networks), is proposed as a tool for supporting IIoT (Industrial Internet of Things) services to achieve optimization and assurance processes of latency, scalability and interoperability parameters required by critical mission services such as health, transportation and production. In this sense, we propose several strategies for assuring low latency, scalability and interoperability in Edge Computing and TSN networks for critical IIoT services. These strategies are evaluated considering different levels of congestion and considering different schemes such as best effort, TSN and Edge Computing.

Enhanced FRER Mechanism in Time-Sensitive Networking for Reliable Edge Computing

“…The reliability of the working path P w and the redundant path P w can be calculated using Equations ( 9) and (10).…”

“…It is also promising for TSN to be integrated with cloud computing and fog computing and leverage their respective strengths. Gomez et al [ 10 ] proposed several strategies that combine TSN and edge computing (EC) to ensure low latency, scalability, and interoperability for critical IIoT services. The paper also evaluated these strategies under different congestion levels.…”
