Title: MESSAGE TRANSMISSION METHOD AND APPARATUS
Abstract:
The present application discloses a message transmission method and apparatus, pertaining to the technical field of communications. The method comprises: broadcasting a first ID sending request in a first broadcast domain, the first ID sending request comprising a first ID number, and the first ID number being a message ID number used by each network node in the first broadcast domain at a current moment to identify the message; sending a first message to a second network node if an ID sending request sent by another network node is not received within a preset period of time, the first message comprising the first ID number, and the other network node being a node in the broadcast domain other than the first network node; updating the ID number synchronously with the other network node in the first broadcast domain after the first message is sent to the second network node, to obtain a second ID number, the second ID and the first ID number satisfying a preset change rule, and the change rule being a monotonic increase rule or a monotonic decrease rule. The present application resolves the problem of a low reliability in determining a duplicate message in a large-scale network. The present application is used for message transmission.
