The invention relates to the technical field of
Internet of Things communication transmission, and discloses an
Internet of Things data intelligent transmission method and
system, and the method comprises the steps: abstracting the performance of a multi-source heterogeneous link through a
software defined network controller, dynamically generating a slice template, carrying out the traffic marking and
priority scheduling, constructing a multi-path target constraint optimization model, and carrying out the optimization of the multi-path target constraint optimization model. And in combination with a network function
virtualization mechanism, multi-level intelligent transmission is implemented at edge nodes, and a final transmission control instruction is generated. In the prior art, in a heterogeneous multi-network environment, low-
delay, high-reliability and high-bandwidth transmission cannot be guaranteed at the same time, and especially in an industrial
automation scene, technical problems that a control instruction is easy to
delay and a
monitoring data bandwidth is limited exist. According to the invention, the overall transmission reliability and
bandwidth utilization efficiency are improved through the dynamic priority traffic scheduling based on network slices, the multipath reliability
product model and the dynamic
batch processing and progressive compression technology based on real-time link feedback.
