Heartbeat detection message sending method and equipment

The invention discloses a heartbeat detection message sending method, which comprises the following steps: judging whether the corresponding data flow rate exists at a client or not by accession equipment; sending a heartbeat detection message to the client by the accession equipment if the corresponding data flow rate does not exist at the client; and determining that the heartbeat detection message does not need to be sent to the client by the accession equipment if the corresponding data flow rate exists at the client. In the invention, the sending times of the heartbeat detection message are reduced, the performance of the accession equipment is improved, and the waste of the network bandwidth is reduced.
