Task and resource matching method supporting destroy-resistant replacement of cross-node computing task

The invention discloses a task and resource matching method supporting destroy-resistant replacement of a cross-node computing task. The method comprises the following steps: acquiring network parameters; calculating an optimization matching relation set for any task scheduling node; calculating a neighbor node set for each task-task execution node pair in the optimized matching relationship set; calculating a link connection frequency predicted value, a link throughput predicted value and a backup resource reuse rate predicted value for each candidate backup node in the neighbor node set; selecting a destroy-resistant replacement node for all task execution nodes corresponding to the task scheduling node; repeating the steps until the destroy-resistant replacement nodes are selected for all the task execution nodes corresponding to all the task scheduling nodes; updating network parameters of the communication network; and repeating the steps to carry out continuous task and resource matching.
