In popular terms, data is transmitted in multiple paths in a distributed manner.
The path available idle bandwidth measurement mechanism is different from the path transmission mechanism in that the path available idle bandwidth measurement mechanism is a path for detecting the nearest or secondary near and the like, and the multipath transmission mechanism is that data is transmitted in a plurality of paths; one for probing and one for transmission.

The above rules are also followed for transmitting non-real time data packets to cloud virtual machine forwarding nodes that are secondarily close to the caching node, and the specific need for transmitting to how many cloud virtual machine forwarding nodes is ascertained depending on how much the aggregate rate exceeds the rate at which the edge nodes collect data. The preset threshold value is set at 80% to reserve sufficient buffer space, so as to prevent the whole buffer space from being occupied and leading to non-real-time data loss.
In this embodiment: the available bandwidth measurement of the path is combined with the multipath transmitter, so that the network bandwidth resource is fully utilized, the transmission efficiency is improved, and the network congestion is effectively avoided.
