Method and system for forwarding data, virtual load balancer, and readable storage medium

A virtual load balancer, the virtual load balancer comprising a memory, a processor, a data forwarding program stored in the memory and performed by the processor, the processor being configured to execute the data forwarding program stored in the memory to perform the following operations:

• when receiving a pending response data packet sent by a Linux virtual server LVS from a front terminal sub interface, sending the pending response data packet to a real server RS through a rear terminal sub interface, wherein the forward network port of the VLB corresponds to at least one front terminal sub interface, and one of the front terminal sub interface corresponds to a carrier's data interface;
• and;
• receiving a response data packet from the RS, the RS obtaining the response data packet after receiving and responding to the pending response data packet;
• and
• transmitting the response data packet to the LVS from the front terminal sub interface that receives the pending response data packet.

A computer-readable storage medium that stores one or more programs, which can be executed by one or more processors to perform the following operations:

• when receiving a pending response data packet sent by a Linux virtual server LVS from a front terminal sub interface, sending the pending response data packet to a real server RS through a rear terminal sub interface, wherein the forward network port of the VLB corresponds to at least one front terminal sub interface, and one of the front terminal sub interface corresponds to a carrier's data interface;
• and
• receiving the response data packet from the RS, the RS obtaining the response data packet after receiving and responding to the pending response data packet;
• and
• transmitting the response data packet to the LVS from the front terminal sub interface that receives the pending response data packet.
