Non-real-time data transmission method and device based on cloud edge collaboration

The invention relates to a non-real-time data transmission method and device based on cloud edge collaboration, and the method comprises the steps: a data source end transmits a connection message to a target server end through a control center, and the target server end transmits a connection confirmation message to the data source end through the control center according to the connection message; based on a path available idle bandwidth measurement mechanism, the data source end and the target server end determine a transmission path through detection; the data source end sends a non-real-time data packet to an edge node based on a path transmission mechanism, and the edge node sends the non-real-time data packet to a cloud virtual machine forwarding node; and the cloud virtual machine forwarding node forwards the non-real-time data packet to the target server end. Through combination of cloud edge collaboration of the edge node and the cloud virtual machine forwarding node, path available bandwidth measur
