Podcast/Software Gone Wild
Software Gone Wild
Are you sick and tired of SDN, NFV, SDDC and network programability hype? You came to the right place - Software Gone Wild is focusing on architectures, solutions and technologies that real networking engineers use in production networks.
Show 72: OpenConfig: From Basics to Implementations
17 February 2017
In 2013, large-scale cloud providers and ISPs decided they had enough of the glacial IETF process of generating YANG models used to describe device configuration and started OpenConfig – a customer-only initiative that quickly created data models covering typical use cases of the founding members (aka “What Does Google Need”).
Show 71: Linux Networking Update from NetDev Conference
3 February 2017
When I recorded the first podcast with Thomas Graf we both found it so much fun that we decided to do it again. Thomas had attended the NetDev 1.2 conference so when we met in November 2016 we warmed up with What’s NetDev and then started discussing the hot new networking stuff being added to Linux kernel:
Show 70: To Drop or To Delay, That’s the Question
27 January 2017
A while ago I decided it's time to figure out whether it's better to drop or to delay TCP packets, and quickly figured out you get 12 opinions (usually with no real arguments supporting them) if you ask 10 people. Fortunately, I know someone who deals with TCP performance for living, and Juho Snellman was kind enough to agree to record another podcast.
Show 69: VXLAN Ping and Traceroute
13 January 2017
From the moment Cisco and VMware announced VXLAN some networking engineers complained that they'd lose visibility into the end-to-end path. It took a long while, but finally the troubleshooting tools started appearing in VXLAN environment: NVO3 working group defined Fault Managemnet framework for overlay networks and Cisco implemented at least parts of it in recent Nexus OS releases.
Show 68: Snabb Switch with vMX Control Plane
9 December 2016
In Software Gone Wild Episode 52 Katerina Barone-Adesi explained how Igalia implemented 4-over-6 tunnel termination (lwAFTR) with Snabb Switch. Their solution focused on very fast data plane and had no real control plane.
No problem – there are plenty of stable control planes on the market, all we need is some glue.
Show 67: StackStorm 101
25 November 2016
A few weeks ago Matt Oswalt wrote an interesting blog post on principles of automation, and we quickly agreed it’s a nice starting point for a podcast episode.
Show 66: Becoming a Programmer
11 November 2016
During our summer team-building podcast we agreed it would be fun to record a few episodes along the “how do I become a programmer” theme and figured out that Elisa Jasinska would be a perfect first candidate.
A few weeks ago we finally got together and started our chat with campfire stories remembering how we got started with networking and programming.
Show 65: NAPALM Update
28 October 2016
We did a podcast describing NAPALM, an open-source multi-vendor abstraction library, a while ago, and as the project made significant progress in the meantime, it was time for a short update.
NAPALM started as a library that abstracted the intricacies of network device configuration management. Initially it supported configuration replace and merge; in the meantime, they added support for diffs and rollbacks
Show 64: Fast Linux Packet Forwarding with Thomas Graf
14 October 2016
We did several podcasts describing how one could get stellar packet forwarding performance on x86 servers reimplementing the whole forwarding stack outside of kernel (Snabb Switch) or bypassing the Linux kernel and moving the packet processing into userspace (PF_Ring).
Now let’s see if it’s possible to improve the Linux kernel forwarding performance. Thomas Graf, one of the authors of Cilium claims it can be done and explained the intricate details in Episode 64 of Software Gone Wild.
Show 63: Distributed On-Demand Network Testing (ToDD) with Matt Oswalt
30 September 2016
In March 2016 my friend Matt Oswalt announced a distributed network testing framework that he used for validation in his network automation / continuous integration projects. Initial tests included ping and DNS probes, and he added HTTP testing in May 2016.
Show 62: Whitebox Switching at LinkedIn with Russ White
15 September 2016
It took us a long while (and then the summer break intervened) but I finally got it published: Episode 62 is waiting for you.
Show 61: OpenStack on VMware NSX
8 September 2016
Does it make sense to run OpenStack on top of VMware infrastructure? How well does NSX work as a Neutron plug-in? Marcos Hernandez answered these questions (and a lot of others) in the Episode 61 of Software Gone Wild (admittedly after a short marketing pitch in the first 10 minutes).
Show 60: Software-Defined Navel Gazing
26 August 2016
Software Gone Wild podcast is well into its toddler years and it was time for a teambuilding exercise. Just kidding – we wanted to test new tools and decided to discuss the vacation experiences and podcast ideas while doing that.
On a more serious note: we’re always looking for cool projects, implementations and ideas. Contact us at podcast (-the weird sign-) ipspace.net.
Show 59: Build Your Own Service Provider Gear
24 June 2016
A few days after I published a blog post arguing that most service providers cannot possibly copy Google’s ideas Giacomo Bernardi wrote a comment saying “well, we managed to build our own gear.”
Show 58: Big Chain Deep Dive
17 June 2016
A while ago Big Switch Networks engineers realized there’s a cool use case for their tap aggregation application (Big Tap Monitoring Fabric) – an intelligent
patch panel traffic steering solution used as security tool chaining infrastructure in DMZ… and thus the Big Chain was born.
Show 57: Using Macvlan and Ipvlan with Docker
3 June 2016
A few weeks after I published Docker Networking podcast, Brent Salisbury sent me an email saying “hey, we have experimental Macvlan and Ipvlan support for Docker” – a great topic for another podcast.
Show 55: Model-Driven Networking
20 May 2016
The Model-driven Networking seems to be another buzzword riding on top of the SDN wave. What exactly is it, how is it supposed to work, will it be really vendor-independent, and has anyone implemented it? I tried to get some answers to these questions from Jeff Tantsura, chair of IETF Routing Area Working Group, in Episode 55 of Software Gone Wild.
Show 56: More Open-Source Network Management Tools
29 April 2016
After listening to Open-Source Network Engineer Toolbox Nick Buraglio sent me an email saying “we should do another podcast on open-source network management tools…” and so we did. In Episode 56 of Software Gone Wild Nick, Elisa Jasinska and myself discussed a whole range of network management challenges and open-source tools you can use to address them.
Show 54: Shortest Path Bridging (SPB) and Avaya Fabric
15 April 2016
A few months ago I met a number of great engineers from Avaya and they explained to me how they creatively use Shortest Path Bridging (SPB) to create layer-2, layer-3, L2VPN, L3VPN and even IP Multicast fabrics – it was clearly time for another deep dive into SPB.
It took me a while to meet again with Roger Lapuh, but finally we started exploring the intricacies of SPB, and even compared it to MPLS for engineers more familiar with MPLS/VPN. Interested? Listen to Episode 54 of Software Gone Wild.
Show 53: Palo Alto Integration with Cisco ACI and OpenStack
1 April 2016
A while ago Christer Swartz explained how a Palo Alto firewall integrates with VMware NSX. In the meantime, Palo Alto announced integration with Cisco ACI and OpenStack, and it was time for another podcast with Christer deep-diving into the technical details of these integrations.
