Method and system for handling DSR load balancing utilizing a loopback interface in a virtual network environment

摘要

A method to process load balancing via a hypervisor node in a virtual network environment includes: generating one or more backend virtual machine servers and a virtual switch responding to the one or more backend virtual machine servers, the virtual switch including a loopback interface; receiving, from a load balancing node via a virtual network, a request packet of a client received at the load balancing node through a router, the load balancing node including an L4 direct server return (DSR) load balancer; generating a response packet by processing the request packet through a backend virtual machine server selected by the L4 DSR load balancer among the one or more backend virtual machine servers, the request packet including an address of the client; and transmitting, according to the loopback interface, the generated response packet to the router of a real network based on the address of the client.
