The application discloses a dynamic message aggregation and distribution method and system. The destination address of an original message in a received message is judged. If the destination address is local, the message is directly sent. If the destination address is not local, it is judged whether the message is repeated according to the message type and content. For the repeated message, message aggregation is performed. The message aggregation includes counting the message identifier of the repeated message and determining the forwarding server list of the aggregated message. The aggregated message is sent to the remote server closest to the local server in the server list. The aggregated message in the received message is dis-aggregated.
