My Cisco Live Milan IPv6 Firsts

That is it, Cisco Live Milan is over! The “before” of anticipation, seemingly a moment ago, is replaced by the “after” of takeaways and accomplishments for the week. Some passed their CCIE certification, some met a new business partner, but it’s likely that everyone learned something new. I am not an exception. During the week, […]

Touching / Seeing / Feeling IPv6 in the World of Solutions at Cisco Live Milan

As Cisco Live Europe 2014 draws to a close I wanted to reflect on what has (for me) been a personal campaign to raise the visibility of IPv6 in the World of Solutions / WoS (the demonstration / show floor of the event) Last year at Cisco Live London I heard some comments that there […]

Programmability in Python: Confessions of a Networking Guy

I am not qualified to discuss it much, but can you guess what this does? ne = NetworkElement("172.16.66.1", "JasonsApp") conn = ne.connect("admin", "cisco", sc) intf1 = ne.get_interface_by_name("FastEthernet0/1") intf1.shut_down(1) sleep(5) intf1.shut_down(0)   If you guessed that it logs into a switch at 172.16.66.1 and disables interface F0/1 for 5 seconds and re-enables it, then you guessed […]

My App anywhere: On devices, on controller, on both!

Current differences in app development on devices and controllers disappear. Devices and controllers will share a common programming environment – offering a unified development and deployment experience. While SDN is moving from concept to reality, we notice that many deployments which focus on creating new network features interpret the role of the “controller” very pragmatically. […]

Autonomic Networking at Cisco Live Milano!

Welcome to Milano! Wow, what an activity on the first day at the Cisco Campus / World of Solutions. It’s great to see all these people thirsty for knowledge, and all these people looking for intelligent solutions for their business needs. One of those business needs is removing complexity from networks by making networks self-managing, […]

Hands On with SDN in Milan

Those of you who follow me know that one of the milestones I have for SDN is when we start turning those unicorns into plough horses.  While I don’t think we are quite there yet, the partner demos you can check out on the floor in Milan show that we are certainly moving the needle […]

Top Things to Know About DFA Before Cisco Live Milan

Two weeks ago, I presented a webinar on Dynamic Fabric Automation (DFA) and went over the allocated 1 hour to cover the content.  Yesterday, as I was doing follow up with a hands-on demo, I went over time too. This illustrates how rich DFA is, and how much there is to say about it! Dynamic […]

Building a useable Autonomic Networking Infrastructure from the Ground Up

Yep, that’s what we did, and yes we are shipping it today! As Michael’s blog explained, autonomics are all around us, both in feature implementation (e.g. a routing protocol like OSPF) as well as in architectural frameworks like GANA.  But while the former has created isolated, per feature domains of autonomicity, the latter has never […]

Quitting the Legacy IP at Cisco Live Milan

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...
