There’s been a lot of talk about “layers” in SDN and even in NFV, and I’ve blogged in the past that most of it is at the minimum inconsistent with real OSI model principles. Some is just nonsense. Interestingly, given that we seem to want to invent layer behaviors ad hoc, we’re ignoring a real…
Policy Management for SDN and NFV
One of the things about hot trends that my surveys tell me frustrates users is the tendency to talk about something but never really define it properly or explain how it would work. We’ve all seen that with things like SDN and NFV. It doesn’t have to be one of the super-revolution trends either; I’ve…
Three Steps to Prove NFV is Justified
NFV is all about hosting virtual functions, and justifying it means that the process of hosting functions is somehow better than creating network services by interconnecting fixed devices and custom appliances. The question is whether that’s true, and it’s a question that’s becoming increasingly important to service provider executives who have to decide whether to…
Could the Next SDN Battleground be the Branch?
It’s hard not to see the VMworld show as anything other than a VMware-versus-Cisco extravaganza, partly of course because that’s how it tends to be portrayed in coverage. Underneath, there is surely good reason to see the networking developments in particular as being contra-Cisco, but I wonder whether there’s more to it. Cisco might be…
Amazon’s Influence Might Change OTT Opportunities, and Create Carrier Opportunities
Amazon isn’t just your mother’s online retailer anymore, obviously. The company has evolved through its position as an ebook provider and public cloud provider, into a video and online music streamer, and now it’s looking at gaming and advertising. Could all of this revolutionize the OTT market? Certainly it could revolutionize Google, but the OTT…
Why SDN and NFV Could Still Fail Utterly
There’s a popular view that as we move into the future, operators will build networks from commodity/commercial off-the-shelf servers (COTS) rather than specialized network equipment. Network Functions Virtualization (NFV) is the poster child for the notion, and there have been a flood of announcements from vendors who have made hosted network functionality available under the…
Brocade Says a Lot About NFV: Is it the Right Stuff?
Most of our discussions of the competitive landscape in networking involve the larger firms; Alcatel-Lucent, Cisco, Ericsson, Huawei, Juniper, and NSN. While it’s true these firms have the most influence and the greatest resources, they also have a powerful incentive to take root in the current market and become trees. Mammals may be smaller, but…
HP’s and IBM’s Numbers Show a Faceoff–On NFV?
HP reported its results and the numbers were favorable overall, with the company delivering year-over-year revenue growth for the first time in three years. The only fly in this sweet ointment was that the great majority of the gains came in the PC division, which saw a 12% increase in revenue that management attributes to…
A Carrier’s Practical View of SDN
Yesterday I talked about the views of a particular operator on NFV trials and evolution, based on a conversation with a very knowledgeable tech guru there. That same guru is heavily involved in SDN evolution and it’s worthwhile to explore the operator’s SDN progress and directions. A good place to start is with the focus…
A Look at an Operator’s NFV Position
I had an interesting discussion late last week with a true thought leader in the service provider networking space. Not a VP but a senior technical person, this individual is involved in a wide range of both SDN and NFV activities for his company, and also involved with other operators in their own efforts. It…
