Abstract

The invention discloses a load balancing method, load balancing equipment and a load balancing system. The method comprises the following steps of: acquiring an address resolution protocol (ARP) request from a client; selecting a load balance node meeting preset load conditions from a load balance cluster, and acquiring a media access control (MAC) address of the load balance node meeting the preset conditions; and transmitting ARP response information to the client, wherein the ARP response information comprises the MAC address of the load balance node meeting the preset load conditions, so that the client transmits a service request to the load balance node meeting the preset load conditions for balancing processing after receiving the ARP response information. In the method, the equipment and the system, the ARP request is acquired from the client, and the load balance node meeting the preset load conditions is selected for the client for the service balancing processing according to the ARP request so as to realize the effective management of the load balance cluster and better the overall balancing processing effects of the load balance cluster.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a load balancing method, device and system. Background technique [0002] A server cluster system gathers multiple servers together to provide services for clients. Clients served by the server cluster system include network access server (Network Access Server, hereinafter referred to as NAS) equipment, packet data serving node (Packet Data Serving Node, hereinafter referred to as PDSN), and gateway general packet radio service technical support node (Gateway GPRS Support Node, hereinafter referred to as GGSN) and other network routing devices. [0003] The server cluster shares the same virtual IP address externally. From the perspective of external clients, it is equivalent to a server providing services for it. In order to avoid unbalanced load borne by each server, it is necessary to use a load balancer (Load Balance, hereinafter referred to as LB) to perform loa...
