METHOD AND SYSTEM FOR PROCESSING DSR LOAD BALANCING USING LOOPBACK INTERFACE IN VIRTUAL NETWORK ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a method and system for processing DSR load balancing using a loopback interface in a virtual network environment.SOLUTION: The method includes: a step of generating at least one backend virtual machine server and a virtual switch responding to the at least one backend virtual machine server and having a loopback interface set thereto; a step of receiving a request packet received via a router by a load balancing node including an L4 DSR load balancer, via a virtual network; a step of generating a response packet by processing the request packet through a backend virtual machine server selected by the load balancer, out of the at least one backend virtual machine server; and a step of, according to the loopback interface, transmitting the generated response packet to the router of a real network on the basis of an IP address of a client which the request packet includes.SELECTED DRAWING: Figure 4
