Importance-aware SDN Control Mechanism for Real-time Data Distribution Services

摘要

Digital twin technology is applied to various industrial domains. It provides diverse and dynamic services to support user's demands. A large number of virtual and physical objects are connected to the network to exchange data to provide various services. Each data of digital twin services has different communication features, which may not meet all of them in a limited network. If high important services fail to operate normally due to communication problem, they can cause fatal errors. We propose a novel SDN control mechanism that can dynamically configure a network by considering the importance and communication quality of services of data. It recognizes the importance and real-time of data from OMG DDS as a communication middleware and allocates network resources to satisfy the requirements. As a result, it can show the good performance in terms of real-time, reliability and stability for various application using DDS.
