Cooperative probability storage method

The invention provides a cooperative probability storage method. The method comprises the following steps: determining a current edge server and auxiliary storage equipment; according to the coverage areas of the edge server and the auxiliary storage devices, dividing the auxiliary storage devices which are not covered by the edge server and covered by the edge server into a first type and a second type respectively; the first type of auxiliary storage equipment is set as an independent storage network, and the second type of auxiliary storage equipment does not store the content stored by the edge server and then stores the content. The auxiliary storage devices are divided into the first class and the second class, repeated storage is avoided, the storage space is saved, and the overall storage efficiency is improved. And meanwhile, the second type of equipment does not store the content stored on the edge server, so that the network transmission quantity can be reduced, and the network load can be reduced.
