P2p-based data distribution method, apparatus, and system

An apparatus, applied to a data distribution system, wherein the data distribution system comprises at least three devices and a server, and the apparatus comprises at least one processor and a memory;

• the memory stores one or more computer programs;
• and
• when the one or more computer programs stored in the memory are executed by the at least one processor, the apparatus is enabled to perform operations comprising:
• sending, by a first device of the at least three devices, request information to the server, and receiving response information sent by the server, wherein the request information is used to request to acquire related information of a second device that is connected to the first device via a peer-to-peer (P2P) channel, and the response information carries the related information determined based on a pre-generated acyclic graph of a data distribution path;
• and
• determining, by the first device, a first target device set from the second device based on the response information, and sending first data to a device in the first target device set, wherein the first data carries identification information of the first device, the identification information is used to indicate the device in the first target device set to distribute the first data to a device in a second target device set when determining the first data as to-be-distributed data, the device in the first target device set is a next-hop device of the first device, the device in the second target device set is a next-hop device of the device in the first target device set, and the to-be-distributed data is data that is to be distributed to all devices in the data distribution system.
