Path optimization in multi-node virtual switch with orphan ports

摘要

Embodiments provide techniques for optimizing paths in a network environment with a virtual network device that includes a first physical network device and a second physical network device, connected using a virtual network device layer link. Embodiments receive a first data packet belonging to a first data flow, at the first physical network device, from the second physical network device, over the virtual network device layer link. An adjacent network device from which the second physical network device received the first data packet is determined. Embodiments also determine one or more links connecting the first physical network device and the adjacent network device. A network message is transmitted to the adjacent network device, where the adjacent network device is configured to transmit subsequent data packets from the first data flow to the virtual network device, using only the determined one or more links, responsive to receiving the network message.

1. A method of optimizing paths in a network environment containing a virtual network device, the virtual network device including a first physical network device and a second physical network device, connected using a virtual network device layer link, and the method comprising:
responsive to receiving a first data packet belonging to a first data flow, at the first physical network device, from the second physical network device, over the virtual network device layer link:
determining, by the first physical network device, an adjacent network device from which the second physical network device received the first data packet;determining, by the first physical network device, one or more links connecting the first physical network device and the adjacent network device; andtransmitting a network message from the first physical network device to the adjacent network device, wherein the network message specifies the determined one or more links, and wherein, responsive to receiving the network message, the adjacent network device is configured to transmit subsequent data packets belonging to the first data flow to the virtual network device using only the determined one or more links.
