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 was not enough IPv6 in the WoS. I decided to see if I could encourage Cisco Business Units and Partners to enable demonstrations for Dual Stack operation and highlight that fact. I wrote previously we would be “awarding” an “IPv6 Enabled Logo” to all Cisco and Partner demonstrations that took the step of enabling Dual Stack and highlighting the same fact.

How did we fare ? Cisco Live 2014 Milano showcased over 15 IPv6 enabled demonstrations including two which were enabled as “IPv6 only”. These were spread between Cisco and Partner booths and were mainly marked with the newly created green “IPv6 Enabled Logo”.

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 right.

Let us talk a little about putting the “ability” in programmability.  Did I code in college? Yes. Was I good at it? Not really. Dijksta’s algorithm (the actual coding bit) drove me crazy, however, actually using and operating networks quickly became my cup of tea. I became a network geek. Subnets? Awesome! Cisco CLI? Sweet. Using Enhanced Interior Gateway Routing Protocol (EIGRP)? Yay! AVVID? Even better. But I never wanted to see C++ or another “program” again.

Fast forward to 2014.  I’m still a networking guy but now I’m seeing code again.  The good news is, maybe like you, I hang out with some really cool people. I challenged a couple of them to help me demonstrate program “ability” to networking people on the show floor at CiscoLive Milan…with me as the test subject! Read More »

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

January 29, 2014 at 12:41 am PST

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. In these deployments, the controller is not used as an independent layer of software which abstracts the entire underlying infrastructure as in the traditional view of SDN (see for example ONF’s SDN Definition). The pragmatic approach to network programming simply extends the distributed development environment of the network devices using a set of qualities offered by the controller.  Developers move those components of their distributed apps to the controller that benefit from the logical centralization or the enhanced resources (CPU, memory) that a controller typically offers while keeping other components on the network devices. Example use cases fall into the categories of distributed network analytics, DDoS thread mitigation, or routing optimization based on performance measurements. What does this mean for our development environment?

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, or in other words Autonomic Networking.  2014 will be the year that we are shipping the first sets of functionality in this space, so that makes us really exited.  After all we have been working on this for more than 3 years internally, and its great to finally see the fruits of that hard work.

Michael has explained in his blog that Autonomics is all around us, but until now there wasn’t a solution that allowed other applications to leverage a common autonomic infrastructure.  Finally it is here!  The Autonomic Networking Infrastructure allows Service Providers to bootstrap new devices completely zero touch, in a secure fashion, without pre-staging the devices and/or a back-end DHCP Server, and this totally topology independent!  Just plug in the device, and watch it getting authenticated, receiving a Domain Certificate, joining the Autonomic Domain, and joining the Autonomic Control Plane, which provides indestructible IPv6 end-to-end connectivity!  If an mdns-enabled TFTP server is connected to the network, it will leverage the Autonomic Control Plane to announce its service, upon which the devices will pull in their configuration!

Hands On with SDN in Milan

January 26, 2014 at 11:49 pm PST

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 with SDN: Read More »
