Proxy address resolution protocol on a controller device

摘要

Techniques are presented herein for reducing network congestion in data center environments. A virtual switch, hosted by a server device in the network, registers with a controller device to enable the virtual switch to exchange address information with the controller device. The virtual switch generates mapping information comprising Media Access Control addresses of one or more virtual machines that are in communication with the virtual switch. The mapping information is sent to the controller device.

1. A method comprising:
at a top of rack (ToR) switch device connected to one or more virtual switches hosted by a server device in a network, sending a registration message to a controller device to enable an exchange of address request messages between the ToR switch device and the controller device; receiving, from the controller device, a configuration message that comprises instructions for the ToR switch device to send any address request messages received from the one or more virtual switches to only the controller device; and based on the configuration message, configuring the ToR switch device to send address request messages received from the one or more virtual switches to only the controller device.
