Data Processing Method, Apparatus, and System

A data processing apparatus, wherein the apparatus is applied to a controller in a data center network, and comprises:

• one or more communications interfaces configured to:
• receive a processing request that is for a specified calculation task and that is sent by a specified node, wherein the processing request comprises identifiers of a plurality of computing nodes configured to execute the specified calculation task, and the plurality of computing nodes comprise the specified node;
• and
• separately send routing information corresponding to the specified calculation task to a target switching device and the specified node, wherein the routing information is used to indicate data forwarding paths between the plurality of computing nodes and the target switching device;
• a processor;
• a memory storing a computer program;
• the processor being execute the computer program to:
• determine the target switching device from switching devices configured to connect to the plurality of computing nodes,
• wherein the routing information is used for the target switching device to send, after the target switching device combines data reported by the plurality of computing nodes, the combined data to each computing node based on the routing information.
