Embodiment Construction

[0027] The embodiment of the present invention provides a data transmission method, device, device and storage medium based on load balancing, which obtains the response data packet returned by the first client and extracts the corresponding target address; according to the target address, the first rule The flow table performs flow matching on the response data packet to set the connection tracking item corresponding to the response data packet; set the kernel address corresponding to the response data packet according to the connection tracking item and whether it conforms to the preset identification information format; if so, according to the kernel address, Use the preset second rule flow table to perform flow matching on the response data packet to set the corresponding target channel address for receiving the response data packet; according to the target channel address, send the response data packet to the corresponding second client through the target load balancing ser...

Abstract

The invention relates to the field of artificial intelligence technology and big data, and discloses a data transmission method and device based on load balancing, equipment and a storage medium. The method comprises the following steps: collecting a response data packet returned by a first client and extracting a corresponding target end address; according to the target end address, adopting a first rule flow table to perform flow matching on the response data packet so as to set a connection tracking item corresponding to the response data packet; setting a kernel address corresponding to the response data packet according to the connection tracking item and judging whether the kernel address accords with a preset recognition information format or not; if yes, performing flow matching on the response data packet by adopting a preset second rule flow table according to the kernel address so as to set a target channel address corresponding to the response data packet receiving; and sending the response data packet to a corresponding second client through the target load balancing server according to the target channel address. According to the invention, the target client or the load balancing server of the data packet backhaul can be correctly selected in the DNAT mode.

Description

technical field [0001] The present invention relates to the field of big data, in particular to a data transmission method, device, equipment and storage medium based on load balancing. Background technique [0002] The L4LB (Level 4 Load Balance) gateway is an essential component in the cloud network, and the typical application is the LVS (Linux Virtual Server, Linux virtual server) in the traditional network; DNAT (Destination Network Server) is used in the financial cloud Address Translation (destination address translation) mode load balancing is particularly important, the purpose is to allow the client IP to be transparently transmitted to RS (Real Server, real service). [0003] When using the DNAT mode, the client (Client) can directly access the RS, or access the RS through the L4LB node. Under the condition of the host Overlay cloud network based on the tunnel mode, the RS can distinguish whether the data packet is from the client or the L4LB node; RS can use src...
