There is more talk these days on mice and elephants.  One option to give these elephants special treatment is to deploy a separate physical network to handle the top talkers and elephant flows.  How can OpenFlow help in a design like this to increase the overall performance of the network?

It's been nearly a week since the Insieme launch and I've yet to write a post about it, but wanted to share the following excerpt that was originally posted in a recent Network World article where Martin Casado comments on Cisco's ACI vs. VMware's NSX.

"NSX supports Citrix XenServer and Red Hat KVM as well as VMware ESX, he says. Support for Microsoft Hyper V is coming. And if the point Cisco's trying to make is that software overlays require a hypervisor, well, NSX can also run on bare metal servers without one, Casado claims. It can create tunnels from a Linux endpoint, he says."

Tunnels to bare metal servers.  Interesting to say the least.

SDSec – have you heard that one before?  This is actually what startup vArmour is preaching – Software Defined Security.  I had the opportunity to talk with one of their guys at ONUG to learn a little bit more about them.  Here is what I found out.
