SDN: The Game Changer

I saw a demo of what the capabilities of SDN is going to be like. I have a feeling that was just the tip of the iceberg.  I saw a packet get routed from one vlan to another in a L2 switch.  Not L3, L2! I'm thinking William at nycnetworkers.com probably had some good info on this. But I'm planning on diving in. More to come.

    Did the packet leave the L2 switch and then return back to it on the other VLAN? If not, then you are right...this is a game changer.

      Thats the thing Brad. We had a 10Meg link up to the L3 core (so that we could verify what we saw), and 100Meg to each PC. Once we pushed that policy, we verified that our FTP transfer went from 10Meg to 100Meg through a monitor we had setup. The L2 did the re-write after we pushed the policy to that switch (a Brocade 6610 with L2 code). All of a sudden, a whole new world was opened up.

    You and I, and whole bunch of network engineers, are going to have to relearn a bunch of stuff.

      You got that right. It may be time to retire. :)
