Problems solved by technology
The load balancing session synchronization can realize the mutual synchronization of the load balancing session between different load balancers. However, most load balancers do not have session synchronization at present, which will cause the load balancer to be abnormal or when the load balancer needs to be upgraded, resulting in the client sending Packet (business traffic) forwarding is abnormal, affecting normal business

The invention provides a method for session synchronization among a plurality of load balancers, and the plurality of load balancers comprise a first load balancer and at least one other load balancer. The method comprises the following steps: the first load balancer receives a first message sent from a client, and the first message comprises source information of the client; the first load balancer determines an actual server by using a predetermined algorithm according to the source information; the first load balancer performs load balancing processing on the first message to obtain a second message; the first load balancer generates a third message based on the second message according to the load balancing processing mode, and synchronizes the third message to each load balancer in atleast one other load balancer. According to the method, when the load balancer needs to be upgraded or is abnormal, even if a certain other load balancer fails, the flow transmission between the client and the server in which communication is established cannot be interrupted, so that the client does not perceive.
Description
technical field [0001] The invention relates to a session synchronization method and a load balancer among multiple load balancers. Background technique [0002] Usually, the message sent by the client is processed by a load balancer in the load balancer cluster for load balancing, and then sent to a certain server in the server cluster. The load balancing session synchronization can realize the mutual synchronization of the load balancing session between different load balancers. However, most load balancers do not have session synchronization at present, which will cause the load balancer to be abnormal or when the load balancer needs to be upgraded, resulting in the client sending Packet (service traffic) forwarding is abnormal, affecting normal business. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for session synchronization between multiple load balancers, the multiple load balancers include a first...
