NAPALM: Integrating Ansible with Network Devices on Software Gone Wild Jun 12, 2015

Show notes

What happens when network engineers with strong programming background and focus on open source tools have to implement network automation in a multi-vendor network? Instead of complaining or ranting about the stupidities of traditional networking vendors and CLI they write an abstraction layer that allows them to treat all their devices in the same way and immediately open-source it.

Network Monitoring in SDN Era on Software Gone Wild May 29, 2015

Show notes

A while ago Chris Young sent me a few questions about network management in the brave new SDN world. I never focused on network management, but I know a few people who do, including Terry Slattery and Matt Oswalt. Interop brought us all together, and we sat down one evening after the presentations to chat about the challenges of monitoring and managing SDN networks.

We started with easy things like comparing monitoring results from virtual and physical switches (and why they’ll never match and do we even care), and quickly diverted into all sorts of potential oscillations caused by overly-dynamic load balancing caused by flow label-based ECMP and flowlets.

Segment Routing 101 on Software Gone Wild May 22, 2015

Show notes

With all the hype around Segment Routing we said: “let’s chat about it, what could possibly go wrong”. The result: Episode 33 of Software Gone Wild. We didn’t get very far into the technical details, but you might still find the overview useful (or not – do tell me how good or useless it is).

Build Your Development or Lab Environment with Ravello Systems May 15, 2015

Show notes

When preparing for my Simplifying Application Workload Migration workshop (coming in webinar format in autumn) I tried to find a solution that would allow me to recreate existing enterprise virtual network infrastructure in a cloud environment. Soon I stumbled upon Ravello Systems, remembered hearing about them on a CloudCast.net podcast, and got in touch with them to figure out whether they could help me solve that challenge.

It turned you might use Ravello Systems’ solution to implement disaster recovery, but I got way more excited about the possibility to use their solution for labs or testing. To learn more about that, listen to Episode 32 of Software Gone Wild.

OpenFlow in HP Campus Solutions on Software Gone Wild May 08, 2015

Show notes

When I finished my SDN workshop @ Interop Las Vegas (including a chapter on OpenFlow limitations), some attendees started wondering whether they should even consider OpenFlow in their SDN deployments. My answer: don’t blame the tool if people use it incorrectly.

Two days later, I discovered HP is one of those companies that knows how to use that tool.

PF_RING Deep Dive with Luca Deri on Software Gone Wild Apr 30, 2015

Show notes

Whenever software switching nerds get together and start discussing the challenges of high-speed x86-based switching, someone inevitably mentions PF_RING, an open-source library that gives you blazingly fast packet processing performance on a Linux server.

I started recording a podcast with Luca Deri, the author of PF_RING, but we diverted into discussing ntopng, Luca’s network monitoring software. We quickly fixed that and recorded another podcast – this time, it’s all about PF_RING, and we discussed these topics:

NSONE – Data-Driven DNS on Software Gone Wild Apr 17, 2015

Show notes

DNS is a crucial component in modern scale-out application architectures, so when Alex Vayl and Kris Beevers from NSONE contacted me just as I was starting to work on my Active-Active Data Centers presentation, I was more than interested to hear what their solution can do.

The result: Episode 29 of Software Gone Wild in which we discussed a number of topics including:

ntopng Deep Dive with Luca Deri on Software Gone Wild Apr 10, 2015

Show notes

PF_RING is a great open-source project that enables extremely fast packet processing on x86 servers, so I was more than delighted when Paolo Lucente of the pmacct fame introduced me to Luca Deri, the author of PF_RING.

When we started chatting, we couldn’t resist mentioning ntopng, another open-source project Luca is working on.

Microsegmentation in VMware NSX on Software Gone Wild Mar 27, 2015

Show notes

VM NIC firewalls have been around for years (they’re also the reason I got my first invitation to the awesome Troopers conference), but it sounds so much better when you call them Microsegmentation (not the one I talked about @ Troopers this year).

Marketing gimmicks aside, VMware NSX includes an interesting in-kernel stateful firewall, and Brad Hedlund was kind enough to explain the intricacies of that feature in Episode 27 of Software Gone Wild

Networking Field Day 9 Wrap-up on Software Gone Wild Mar 20, 2015

Show notes

A few days after the Networking Field Day 9 event Nick Buraglio organized a virtual meetup with Brandon Carroll, Brandon Mangold, Bob McCouch and myself, and we discussed the presentations from NEC, Cumulus, Cisco and Brocade. Nick recorded the conversation and so Episode 26 of Software Gone Wild was born.
