Abstract

In one embodiment, a method includes receiving a request packet at a flow director in communication with a plurality of servers, each server comprising a virtual load balancer module and one or more virtual machines and forwarding the request packet to one of the virtual load balancer modules at one of the servers. The virtual load balancer module is configured to select one of the virtual machines to receive the request packet and transmit a response packet. The response packet is transmitted without passing through the flow director. An apparatus for load balancing in a virtual machine environment is also disclosed.
