Link Aggregation in OpenFlow Environment
One of my readers couldn’t figure out how to combine Link Aggregation Groups (LAG, aka Port Channel) with OpenFlow:
I believe that in LAG, every traditional switch would know how to forward the packet from its FIB. Now with OpenFlow, does the controller communicate with every single switch and populate their tables with one group ID for each switch? Or how does the controller figure out the information for multiple switches in the LAG?
As always, the answer is “it depends”, and this time we’re dealing with a pretty complex issue.

and after it a new dawn, but as any wise person will tell you, not before the last light of the sun casts long shadows across the landscape. I often wonder at the sequence of events, coincidences, accidents, opportunities and more that led to the formation of the person that is now my wife. The character […]

For those who do not know, today, in the United States we hold a day of memory — Memorial Day — for those who have fallen in the defense of the freedom of our Nation. This is different from Veteran’s day, a day which honors those who either are or have served in the US Military, in that it is focused on those who have died in the actual service of the United States — in the course of duty, as it is often said.

On this Memorial Day, as we honor the memory of brave men who have borne our colors in war, we pray to God for His mercy. We pray for the wisdom to find a way to end this struggle of nation against nation, of brother against brother.
