Message transmission method and device

The embodiment of the invention provides a message transmission method and device, and relates to the technical field of communication. The method is applied to network equipment, and comprises the following steps: receiving a message which corresponds to a plurality of output ports; determining a target output port from the plurality of output ports, and determining a target aggregation scheduling queue from a plurality of aggregation scheduling queues; determining a target local scheduling queue corresponding to the target aggregation scheduling queue from a plurality of local scheduling queues corresponding to the target output port; caching the message to the target local scheduling queue; and when the scheduling period of the target local scheduling queue is reached, forwarding the message cached in the target local scheduling queue through the target output port. By applying the technical scheme provided by the embodiment of the invention, the bandwidth of message transmission can be improved, and the m
