Software-Defined Collaborative Scheduling of Computing and Network Resources

In the Industrial Internet of Things (IIoT) environment, time-sensitive tasks require efficient utilization of computing and network resources to ensure timely completion and fast processing. However, using existing scheduling schemes based on software-defined network (SDN), time-sensitive network (TSN), or information technology (IT) can lead to problems such as resource inefficiency, transmission delays, and task timeouts. To overcome these challenges, this paper proposes a collaborative scheduling method that combines SDN for global resource management and TSN for precise resource allocation. Additionally, a control plane algorithm is introduced to adapt task resources. This approach effectively schedules global computing and network resources, enabling timely and efficient task processing. Extensive experiments demonstrate the superiority of this method in terms of task completion rate and processing time compared to other baselines in various network environments.
