Method for processing request message, sending method, node and system thereof

The present invention provides a method for processing request message, sending method, node and system thereof. Said method comprises: receiving the request message sent by a remote node; judging whether said request message is a champion message, and processing said request message if the judging result is yes, otherwise refusing said request message; wherein, said champion message is the request message that local node can process preferentially. In the technical solutions of embodiments of the invention, a node can just process the champion message and refuse to process the message which is not a champion message, thus decreasing the hardware resource consumption of the node processing the request message.
