Abstract
The invention discloses a message withdrawal method for preventing withdrawal conflict. The method comprises the following steps: firstly, selecting a message transmission path with minimum number of intermediate nodes as an optimal message transmission path, and when a message needs to be withdrawn, determining whether a message withdrawal request needs to be sent or not by judging whether the intermediate nodes of the message transmission path have a record that a feedback message sent by a destination node passes through the nodes or not; when source nodes send the message withdrawal request and the withdrawal request reaches a next node of the source nodes in the message transmission path, judging whether the node has a record that the feedback message sent by the destination node passes through the node or not to further determine whether the message can be withdrawn or not. Therefore, the situation that the message withdrawal request is invalid as the message withdrawal request and the message feedback information are not at the same node but the message feedback information is sent due to cross transmission is avoided.
