Traffic optimization using network address and port translation in a computer cluster

摘要

Techniques are presented herein for optimizing and load balancing network traffic exchanged between devices in a network environment. At a first device in a cluster of devices in a network, a packet is received from a second device in the cluster. The packet comprises identifier information that is assigned to the first device. The identifier information is reassigned to the second device in the cluster such that subsequent packets with the identifier information are sent directly to the second device. A mapping table is updated to indicate that the identifier information is reassigned to the second device.

1. A method comprising:
at a first device in a cluster of devices in a network, receiving from a second device in the cluster a packet that is designated to be directly received by the first device from a device outside the cluster but is redirected to the second device from the device outside the cluster, wherein the packet comprises identifier information that is assigned to the first device, and wherein the identifier information comprises a public address assigned to the first device; reassigning the identifier information to the second device in the cluster making the second device a master device in the cluster such that subsequent packets with the identifier information are directly received by the second device; and updating a mapping table to indicate that the identifier information is reassigned to the second device.
