I have tested it in a lab environment and used several different
controllers. I agree it seems to be great for a data center and possible
as a Metro switching environment. I have been trying it agains other
carrier mpls/mef hardware. It really can't match the switching times and
resiliency that current hardware and standard deployment. The main
problem becomes the latency between the controller and the device. They
have some tricks to make fast fail over sub 50ms switches operate as
efficiently as the current offerings of most vendors mpls. Give it a few
years though and I am sure that it will be a new story. The management
and human error elimination will be worth it for most carriers.

I’m hearing the opposite, great in the core, not as necessary on fringes.
I’ve got friends migrating core data center switches and routers to
OpenFlow.
So the hardware concentrates on the actual packet flows only (Data
layer) and let’s a controller define the complicated stuff across
multiple devices.
I’m thinking it could be useful for fiber providers running multiple
network segments selling capacity with less complication and hard coding.
I’m already spanning my small fiber network with several services and
tunnels for other providers.
Static entry tables for loopbacks and VPLS paths are becoming cumbersome
already.
Maybe this stuff will help a bit with that?
Not sure.
Maybe it’s still too fringe.

From what I've read it is better for places where you need to manage
flows and not so much in the core, mainly due to whatever is hardware
accelerated.

Anyone implemented OpenFlow in anything?
What are the advantages to an ISP?
I just bought a switch with OpenFlow capabilities to play with.
Not sure what I'm doing, lol!
