Heartbeat detection message sending method and equipment

Abstract

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.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for sending a heartbeat detection message. Background technique [0002] In a traditional network environment, users can access devices or resources in the network as long as they can access LAN devices. In order to strengthen the security control and operation management of network resources, it is necessary to control user access in many cases. For example, in some public places, residential areas or network access points of companies, providers who provide access services hope to only allow paid legal users to access. Therefore, the provider needs to provide each user with an account for accessing the network and password. In addition, some enterprises will provide some internal key resources for external users to access, and hope that only users with valid authentication can access these resources. [0003] Based on the above situation, existing a...

Problems solved by technology

[0030] However, when using ARP or DHCP periodic handshake to determine whether the client is abnormal, the heartbeat detection message (ARP heartbeat detection message or DHCP heartbeat detection message) may be lost due to the instability of the wireless network, resulting in Clients that go online normally may be forced to go offline

[0031] And frequently send ARP heartbeat detection message or DHCP heartbeat detection message from BRAS control plane, can cause the CPU (Central Processing Unit, central processing unit) occupancy rate of BRAS is very high, influence system performance; In this case, the client may go offline abnormally due to the loss of heartbeat detection packets.
