It’s that time of the year again -- time for some computer and human networking at Cisco Live Milan! This year I’m taking the unusual and somewhat risky step of blogging about the network infrastructure before the event. This is because we’re going to try something interesting for the networking folks. We are going to try and get rid of the Legacy IP, otherwise known as IPv4.
Before you get too worried -- no, the dual stack network setup does not disappear. Lots of critical parts of our everyday lives still need the old and proven protocol to successfully operate, so removing it would be irresponsible to say the least. But some of you may be interested to try (in a controlled fashion) exactly how strong the ties to the old good legacy. If you are one of these people, this post is for you -- because this blog entry is one of the few places, if not the only one, to find the IPv6-only SSID name and access credentials.
First of all, what’s the big deal with IPv6-only access network, wasn’t this tried before?
Sure, it is not all new. The first time we tried an IPv6-only network was at IPv6 World Congress conference in Paris, early spring 2012. We also had an IPv6-only SSID in one of the Cisco Live US conferences. We discovered that the subset of the operating systems that could successfully operate in this kind of environment was pretty small. But as time passed, evidence suggests the situation was slowly improving. Read More »

Tuesday of CiscoLive Milan (#CLEUR for the Twitter among you) the keynotes will be wall to wall Rob with Rob Lloyd at 9:30 followed by Rob Soderbery at 11:15. These should be pretty interesting and give you a good foundation to where Cisco is headed overall and specifically in our core networking.
Opening Keynote with Rob Lloyd,President of Development and Sales, Cisco
Tuesday, Jan 28, 9:30 – 10:45AM
Hear from Rob Lloyd on how Cisco and the ecosystem of Cisco’s partners are uniquely positioned to connect the unconnected with an open standard and an integrated architecture from the cloud to end devices. Rob will share his vision of the Internet of Everything and examine the industry trends and technologies that are making that vision a reality.

Cisco Live Milan is around the corner and I’m getting my session, The Hitchhiker’s Guide to onePK, ready for it’s European debut. While it’s lovely to be in the CiscoLive Distinguished Speaker Hall of Fame, putting a good presentation together hasn’t gotten any easier. The hard questions still need to be asked: Do I have too many slides? Have I crossed the line between technical and boring? Will the demos work? Will anyone laugh at my jokes?
And perhaps most importantly for this session: does anyone read Douglas Adams any more?
Here’s why. I borrowed the title of Douglas Adam’s iconic Hitchhiker’s Guide to the Galaxy for good reason. The original Hitchhiker’s Guide follows an ordinary guy, Arthur Dent, as he is unwillingly dragged into an intra-galactic adventure, with little more than the Guide, a pint of beer and a packet of peanuts to see him through. Faced with the vast and confusing world of Software Defined Networking (SDN) and programmability, network engineers are in a position to know exactly how Arthur Dent felt. New buzzwords, emerging standards, an abundance of marketing slides with vague but brightly colored blobs, and a lot of talk about programming languages can be disorienting to the best of us.
Enter the Hitchhiker’s Guide to onePK.
Notice that I did not call my session the Hitchhiker’s Guide to SDN. SDN calls for more of an Encyclopedia Galactica than a Hitchhiker’s Guide, if you know what I mean. Instead, my aim is to take a deep dive into one aspect of network programmability that network engineers can really relate to: onePK. Read More »

Autonomic Networking is well understood in theory, but real, consistent and extensible implementations don’t exist. In this post I suggest a reason for the lack in execution, and our vision to provide a working, implementable Autonomic Networking Architecture.
Wipe off the dust…
When asking a researcher about autonomic systems, (s)he might blow the dust off a stack of papers, or proudly pull a couple of old books off his shelf. Or point to IBM’s IEEE paper from 2003. From a research perspective, autonomics is well understood. It’s this self-management thing, with all those self-* properties. Self-configuration and self-optimisation for example. Distribution, control loops, and so on. Even the Wikipedia articles are written. So, we’re done, aren’t we?
No we’re not.
Ask your friendly neighbourhood network engineers about Autonomic Networking. The one that proudly hacks expect scripts at night to make his admin database talk to his routers. Or the front line engineer who applies a network service class to one of his customers. Likely, both of them would look at you with big eyes, and after explaining that the network manages itself, intelligently, you’d hear back: “That’s like Skynet, isn’t it?”
No it’s not. Read More »

I am sitting and reflecting here at the start of Cisco Live London. As I walk the halls, I continue to be amazed by the size, depth, and breadth of this event. Networking continues to grow, and thousands of people are eager to come together to see the latest. Read More »
