Communication method, communication network, switch node, and storage medium

A communication network, comprising:

• switch nodes at a plurality of layers, wherein the plurality of layers comprise a first layer and a second layer, different first-layer switch nodes communicate with each other via at least one second-layer switch node, the first-layer switch nodes comprise a plurality of first target switch nodes, and the at least one second-layer switch node comprises at least one second target switch node;
• wherein the plurality of first target switch nodes are configured to:
• receive to-be-computed data of a same periodic compute task and target communication task identities (IDs) corresponding to the to-be-computed data that are sent by a plurality of compute nodes, wherein the plurality of compute nodes generate a plurality of communication tasks during execution of the compute task, each target communication task ID indicates one of the plurality of communication tasks, and the target communication task IDs sent by all of the plurality of compute nodes are the same;
• and
• compute the to-be-computed data, to obtain intermediate data, and send the intermediate data and the target communication task IDs to the at least one second target switch node;
• wherein the at least one second target switch node is configured to:
• receive the intermediate data and the target communication task IDs;
• compute the intermediate data corresponding to the same target communication task IDs, to obtain a data compute result;
• and
• send the data compute result to the plurality of first target switch nodes;
• and
• wherein the plurality of first target switch nodes are further configured to send the data compute result to the plurality of compute nodes that execute the compute task.

A switch node in a communication network, comprising:

• at least one processor and memory, wherein the memory stores instructions, and the at least one processor executes the instructions stored in the memory, to cause the switch node to:
• perform the following:
