The present application provides a message scheduling method, device, and network chip, which are applied in a network chip. The network chip includes a classification layer, and the classification layer includes a plurality of classification nodes; and the method includes: when the classification node obtains After the scheduling task of the network message, obtain the node identification of the classification node; according to the mapping relationship between the stored node identification and the queue identification of the output queue, determine the queue identification corresponding to the node identification of the classification node; determine the determined queue Identify whether the corresponding output queue satisfies the backpressure condition; when the backpressure condition is met, the scheduling task is abandoned; when the backpressure condition is not met, the scheduling task of the network message is executed so that the above network message is written to Determine the output queue. By adopting the above method, the dispatching of network messages is realized at the L3 layer, which effectively avoids the congestion problem caused by the excessive buffer size of the output queue, and reduces the buffer pressure of the corresponding output queue.
