When data that requires more computation resources is being processed, the data is usually divided, and then multiple pieces of partial data obtained through division are allocated to multiple computation nodes for processing. After processing the allocated partial data to obtain partial computation results, the computation nodes collect the partial computation results obtained by these computation nodes through processing, to obtain a computation result corresponding to the data, which is distributed computing.
In the prior art, when distributed computing is used, a scheduler platform first decomposes a received computation task submitted by user equipment (UE), and then sends a computation resource application request to a computation resource manager. The computation resource application request includes at least a quantity of computation nodes. After receiving the computation resource application request, the computation resource manager allocates computation nodes for the computation task according to the quantity of computation nodes, and then feeds back, to the scheduler platform, a computation resource application response that carries an allocation result. The allocation result includes information about the allocated computation nodes. The scheduler platform sends each piece of partial computation subtasks obtained through decomposition to the corresponding computation nodes and then collects partial computation results from the computation nodes, thereby completing processing of data that requires more computation resources. One computation node executes one piece of partial computation subtask.
However, when a prior-art manner is used to process data (a computation task) that requires more computation resources, after a scheduler platform delivers computation subtasks to allocated computation nodes, a network device (for example, a switch or a router) can perform routing control only according to a pre-configured static policy when there are more data exchanged between the computation nodes. As a result, communication congestion may occur between network devices.
