Nobody is sending an MRI to a residential cable customer. That's what this discussion is about, limiting customers abilities to access products that compete with the ISPs own, like video. Hospitals already buy dedicated private networks for their information systems, and I suspect that's driven more by billing than MRI images.
I'm interested in it for telecom networks. We've got thousands of miles of network and a lot of techs and 'engineers' that don't really understand the technology. Even for the guys who do understand it through and through, creating or making changes to a circuit/service can take hours today. What I want to see is an application running on an SDN stack that makes it easy to create MEF type circuits, especially across different vendors and technologies. If I need to build an EVPL from A to D, I may have a simple QinQ Cisco switch network from A to B, an 802.11qay Cyan packet-optical switch network from B to C, and full-on Juniper MPLS from C to D. If I have one tech who can go in, select his port and VLAN on both ends, approve or modify the suggested path, and then push the provisioning out to all the devices then I have saved hours at least, possibly weeks of muddling between different departments. Add in seamless control of OTN switches, DWDM optical switches, we're talking a huge benefit without doing anything technically that we aren't already doing today, just doing it in a less manual fashion.
I can see where a large network would need a few million rules, but each individual device shouldn't except for the core of the network, and those are going to need to be on the scale of the MX series anyway to support the bandwidth. Then again, my perspective is from Telecom. Most of my network is relatively few flows, but each at a pretty high volume.
Not sure what you mean by 'useful amount'. Hell, Google has been using SDN for years. Where SDN really shines today is top of the rack datacenter switches like the HP 5900 series. Those cost about as much as a power supply for one of those Juniper MXes.
Oh, and I'm replying to myself here, Cyan has been doing SDN for years, although not necessarily with OpenDaylight. They've got a centralized control plane for provisioning and operating DWDM, Sonet, Carrier Ethernet, and has integration with other vendor equipment, mostly Overture and Accedian.
Coriant did an SDN demo at OFC that was pretty slick, building on-demand carrier Ethernet services and controlling both the layer 1 optical and layer 2 Ethernet devices from one GUI. It may be on Youtube or their website.
This is likely to make Cisco a no-go once SDN starts taking off. A lot of the demos and projects from other layer 1, 2 and 3 equipment manufacturers use OpenDaylight, and it could give us seamless multi-vendor networks in the future. This is why Cisco doesn't support it, and others like Juniper, Coriant, Ciena do (just naming vendors I deal with, haven't even bothered to check the OpenDaylight list).
Netflix doesn't compete with Akamai, Limelight, et cetera. They are cutting out the middle-men. Everyone benefits except the middle-men CDNs, including the ISP in the form of reduced operating costs.
There are large US ISPs that are playing ball, setting up 10GE peering points and also deploying caching appliances. This includes the one I work for. It's only the dickhead ISPs that are trying to 'monetize' their customers. Netflix gives you the caching appliance for free and it immediately reduces your backhaul/transit needs. It's literally a no brainer. You have to have negative values of brain to not do this.
They're both very expensive if you have to have the best of everything, or at least higher end. They're both pretty affordable if you want to pick up used gear and mess around locally.
I'd mod you up if I had points. Augusta National != Golf. The course down the road from me costs $9. Most of the others in the area range from $13 to $25. This is not an expensive hobby, compared to my other hobbies of home-brewing or motorcycling. My 'rich man' hobby is cheaper than my 'redneck' hobbies.
They must just be asking a lot of people who are understand math and have a little discipline. A carpenter can become a millionaire by retirement, all you have to do is start saving and keep saving.

Yeah, I see what you mean. Right now I am pretty focused on EPL and EVPL, but E-TREE and ELAN could be several orders of magnitude more flow entries.
Also, most health care providers are already paying vast sums for VPN services, this stuff doesn't hit the public internet.

Why would they offer the service at all if they would be losing money on it?
To stop google fiber from expanding, hence the article.
You're right, but Aaron was prosecuted not for what he did, but for HOW he did it. Scary computer stuff. This is also scary computer stuff.

So go pick a fight with Boko Haram.
"That 'virtually impossible' part was said before they built those plants as well" Of course, they are all so old it was said in Latin at the time.

They solved the puzzle, but didn't compare their solution to the one printed upside down on the bottom of the page yet.
By that reasoning, I really wish you had voted for the current president.
So you would need a way to lock up the wood after the tree is cut down.
Where do you think coal comes from?
Toxins are almost as bad as Chemicals!
You should use my Windows 7 laptop. It's takes several minutes to get my email open when I come in to work.
