The invention discloses a software-defined industrial Internet of Things resource scheduling method, which aims at traffic from a task source to a computing node to perform allocation and path planning of the computing node, performs iteration on a global network view for scheduling of each task through computation of introducing a sink node on a global view to assist algorithm, and finally obtains an allocation scheme of all the tasks. The method provided by the invention can balance situations of occupation to link resource and computing resource by tasks under the premise of guaranteeing time delay of the tasks, can ease generation of link congestion to a certain degree and simultaneously enables the load of the computing node to be balanced as much as possible; moreover, the method canschedule the tasks with the lowest cost under limitation of the task time delay, and can reduce influence on the other nodes in a computing unloading process; meanwhile, the method has low complexityand can be effectively used in computing unloading of the actual software-defined industrial Internet of Things.
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...
