Therefore, there is great inconvenience in the deployment of load balancing devices, and some business-critical systems cannot even deploy load balancing devices
Moreover, because the existing deployment method cannot make the load balancing device transparent and invisible to other devices in the network during deployment, once the load balancing device fails, it is difficult for maintenance personnel to restore the normal state of the entire network in a short time. operate

Embodiment Construction
[0058] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0059]The invention provides a method for processing data based on a load balancing device. When deployed in the network, the load balancing device is transparent and invisible to the client and the server, and the IP addresses and login port numbers of multiple servers can be configured in the load balancing device in advance, so that the virtual IP It can be the IP address of multiple servers, and the port number can also be the login port number of the server, of course, it can also be the same as the IP address and login port number of some servers; moreover, the gateways of multiple servers always point to the firewall. After the client sends the data packet, the data packet sent by the client is intercepted by the load balancing device, and the data packet is forwarded, answered, and load-balanced according to t...

The invention discloses a data processing method based on load balancing equipment. The method includes the steps of receiving a data package sent by a client, judging the type of the data package, if the data package is an access data package containing the address of the load balancing equipment, performing protocol processing and load balancing scheduling on the data package, and forwarding a response data package returned by a server to the client. The invention further provides the load balancing equipment. The access data package which has access to the server and is sent by the client is intercepted and scheduled, so that the address of the load balancing equipment contained in the access data package is the IP address of the server, and a source address in the response data package returned by the sever is consistent with the address of the load balancing equipment in the access data package. Thus, the load balancing equipment is transparent and invisible to the client and the server, and when the load balancing equipment has a fault, continuity of services can still be ensured.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for processing data based on a load balancing device and the load balancing device. Background technique [0002] At present, when deploying load balancing equipment, it can only be deployed in "routing mode", "bypass mode", and "triangle transmission mode". Devices are transparent and invisible. Using the existing deployment method, when deploying the load balancing device to the network, it is necessary to modify the configuration of other devices in the network (such as the server to be loaded), and even modify the server or client code. Therefore, it is extremely inconvenient to deploy load balancing devices, and some business-critical systems cannot even deploy load balancing devices. Moreover, because the existing deployment method cannot make the load balancing device transparent and invisible to other devices in the network during deployment, once the load...
