Debates in the SDN controller space
Not too long ago, in all meetings with people close and less close to the matter there always was the same question… which controller do you work with? ONOS or Open Daylight? And why that one? Why not the other? Religious debates… where have they gone? Why has it become so quiet? And is there anything we can learn from them?
In a second blog Andreas Hegers takes a step back from software revolution
Really? What's going on with this guy, I hear you say. In his last blog he’s praising the beauty of standards, and now he’s going completely retro? Hardly anyone is talking about anything but the endless opportunities of software these days. It’s even difficult to find a decent webinar that talks about Hardware … how dare I?
Optics is Going Software
I recently gave a lecture at Georgia Tech to a group of graduate students. After the lecture, I had a student approach me and ask, “I am really interested in telecommunications. What areas should I study?” My answer was “Either the fundamentals of high speed optics … or software. Software is where the networks are moving.”
SDN and NFV Landscapes Have Not Gotten Any Clearer
The technical content of this year’s BCE was, as usual, presented by some of the best and brightest minds in telecom. Unfortunately, most of those minds were in agreement that the landscape for SDN and NFV, in particular, has not gotten any clearer in the last year. In fact, in many ways the clouds have gotten denser.
The Telecom Industry is Characterized by Ongoing Hype Cycles
Probably more than any other industry sector, the telecommunications market has the habit of jumping from one hype cycle to the next, with only short phases of realism and depression in between. As opposed to other industries, both vendors and customers seem to be participating in this vicious circle - ‘full steam’. Neither side wants to be woken up, let alone stopped.
Open Source Routers?
In the old westerns (often actually shot in Italy or Mexico, rather than the Western United States), when a new gunfighter strolls into town there will always be that fateful moment when someone will say, “this town ain’t big enough for the two of us.” Then some arrangement will be made to meet at dawn on the main street. In the routing world, the problem is often not too many gunfighters, but too few, particularly when it comes to routing stacks. There are a few, of course, including Cisco, Juniper, IP Infusion, Ericsson, and some other well-known names.
What Can Telecoms Learn from Artificial Intelligence?
The field of artificial intelligence (Al) has tickled human interest for decades. It began in earnest in the mid-20th century when a group of scientists and programmers presented the world’s first true “artificial intelligence program: the Logic Theorist”. Since then, top scientists and practitioners have proven repeatedly how we can teach computers to do human tasks.
Thoughts from MPLS+SDN+NFV Paris March 2017
Kudos to the organizers who do a great job of keeping this long running event fresh and relevant, even as they continue adding acronyms to its name. I had the distinct pleasure this year of presenting an opportunity for SPs to offer cyber security as a managed service to business customers, by exploiting network function virtualization.
The Latest in the SDN Series
So far in this series on Software Defined Networks (SDNs), I’ve discussed a basic taxonomy that can be used to classify SDNs, some of the challenges with actually building a control plane, and examined several SDN and SDN-like solutions through the lens of the southbound interface. In order to help you understand the problem space better, this post will consider the CAP theorem in relation to the concept of an SDN.
Why SDN Requires a Different Business Model
In consumer marketing we are familiar with the concept of giving a way one product (or selling it at a heavily discounted price) in order to build a market for even larger sales of another product. Giving away the razor to sell the blades is the classic example, and a more modern one is giving away the printer to sell the ink cartridges.
