A method to load balance via a load balancing node in a virtual network environment, the method including: receiving a request packet from a client through a router; selecting, via a load balancer of the load balancing node, a backend virtual machine server to receive the received request packet; generating, via a virtual switch of the load balancing node, a packet for virtual networking by overlaying information for transmitting the received request packet to the selected backend virtual machine server through a virtual network to the received request packet; and transmitting the generated packet for virtual networking to a hypervisor node including the selected backend virtual machine server.

Method and system for processing load balancing using virtual switch in virtual network environment

A computer device forms a scope controller for a cloud network, including: memory configured to store a computer-readable instruction; and at least one processor configured to execute the instruction, wherein the cloud network may include: hypervisors classified as a plurality of scopes including a first scope; and virtual machines generated by the hypervisors, wherein the at least one processor is configured to: switch, using a virtual switch of the scope controller, a packet communicated between virtual machines generated by hypervisors classified as the first scope, and a packet received from an outside of the first scope, and route, using a virtual router of the scope controller, a packet communicated between the scope controller and a router for connecting to an outside of the cloud network, and a packet communicated between the scope controller and a different scope controller assigned to a different scope other than the first scope.

Cloud network architecture

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.
