The invention discloses a software-defined industrial Internet of Things resource scheduling method, which allocates computing nodes and plans paths for the flow from task sources to computing nodes, and assists the calculation of algorithms by introducing sink nodes on the global view. The scheduling of each task is iterated on the global network view, and finally the allocation scheme of all tasks is obtained. The present invention can balance the occupancy of link resources and computing resources by tasks on the premise of ensuring the time delay of tasks, slow down the occurrence of link congestion to a certain extent, and at the same time make the load of computing nodes as balanced as possible; Under the task delay limit, the task is scheduled with the minimum cost as much as possible, reducing the impact on tasks under other nodes during the calculation offloading process; at the same time, the complexity of the method is low, and it can be effectively applied to the calculation of the actual software-defined industrial Internet of Things Uninstalling.
Description
technical field [0001] The invention belongs to the technical field of network resource scheduling, and in particular relates to a software-defined industrial Internet of Things resource scheduling method. Background technique [0002] Computing offloading technology refers to placing computing tasks on remote devices, which are usually called computing nodes. In actual IoT applications, considering the energy consumption and mobility of IoT terminals, the actual computing tasks of these terminals are often completed by computing offload. The real-time performance of task processing is a key indicator for an Internet of Things application, especially an industrial Internet of Things application, which requires that the time delay generated during the calculation offloading process must meet the requirements of the task itself. At present, common computing offloading technologies include cloud computing and fog computing. Considering real-time performance, the mainstream sol...
