Abstract:
1. A computer-implemented method to perform direct server return in a cloud computing platform, the method comprising: receiving a message addressed to a public interface of a load balancer connected to multiple servers; selecting one of the servers to process the message; modifying the message to include a media access control address of the selected server as the destination media access control address and retaining the internet protocol address of the load balancer as the destination internet protocol address of the message; transmitting the modified message to the selected server associated with the destination media access control address, wherein the server has a loopback interface configured to match the internet protocol address of the load balancer and is configured to communicate a reply to a source of the message without traversing the load balancer; and not responding to address resolution protocol requests that specify the internet protocol address of the load balancer even if the servers have a loopback interface configured to match the internet protocol address of the load balancer.
