Smart or Dumb NICs on Software Gone Wild

9/21/2018
More
Hardware vendors are always making their silicon more complex and feature-rich. Is that a great idea or a disaster waiting to happen? We asked Luke Gorrie, the lead developer of Snabb Switch (an open-source user-land virtual switch written in Lua) about his opinions on the topic. TL&DL version: Give me a dumb NIC, software can do everything else. If you want to know more, listen to Episode 93 of Software Gone Wild. Listen to the podcast

Is BGP Good Enough with Dinesh Dutt on Software Gone Wild

8/31/2018
More
In recent Software Gone Wild episodes we explored emerging routing protocols trying to address the specific needs of highly-meshed data center fabrics – RIFT and OpenFabric. In Episode 92 with Dinesh Dutt we decided to revisit the basics trying to answer a seemingly simple question: do we really need new routing protocols? Read more ...

Network Automation with Nornir (formerly Brigade) on Software Gone Wild

8/10/2018
More
David Barroso was sick-and-tired of using ZX Spectrum of Network Automation and decided to create an alternative with similar functionality but a proper programming language instead of YAML dictionaries masquerading as one. The result: Nornir, an interesting network automation tool formerly known as Brigade we discussed in Episode 90 of Software Gone Wild. Read more ...

Snabb Switch Update on Software Gone Wild

6/8/2018
More
In 2014, we did a series of podcasts on Snabb Switch (Snabb Switch and OpenStack, Deep Dive), a software-only switch delivering 10-20 Gbps of forwarded bandwidth per x86 core. In the meantime, Snabb community slowly expanded, optimized the switching code, built a number of solutions on top of the packet forwarding core, and even forked a just-in-time Lua compiler to get better performance. To find out the details, listen to Episode 91 of Software Gone Wild in which Luke Gorrie explained how...

OpenFabric with Russ White on Software Gone Wild

4/20/2018
More
Continuing the series of data center routing protocol podcasts, we sat down with Russ White (of the CCDE fame), author of another proposal: OpenFabric. As always, we started with the “what’s wrong with what we have right now, like using BGP as a better IGP” question, resulting in “BGP is becoming the trash can of the Internet”. Read more ...

Data Center Routing with RIFT on Software Gone Wild

3/30/2018
More
Years ago Petr Lapukhov decided that it’s a waste of time to try to make OSPF or IS-IS work in large-scale data center leaf-and-spine fabrics and figured out how to use BGP as a better IGP. In the meantime, old-time routing gurus started designing routing protocols targeting a specific environment: highly meshed leaf-and-spine fabrics. First in the list: Routing in Fat Trees (RIFT).

Linux Interfaces on Software Gone Wild

3/9/2018
More
Continuing the Linux networking discussion we had in Episode 86, we focused on Linux interfaces in Episode 87 of Software Gone Wild with Roopa Prabhu and David Ahern. We started with simple questions like “what is an interface” and “how do they get such weird names in some Linux distributions” which quickly turned into a complex discussion about kernel objects and udev, and details of implementing logical interfaces that are associated with ASIC front-panel physical ports.

Packet Forwarding on Linux on Software Gone Wild

1/19/2018
More
Linux operating system is used as the foundation for numerous network operating systems including Arista EOS and Cumulus Linux. It provides most networking constructs we grew familiar with including interfaces, VLANs, routing tables, VRFs and contexts, but they behave slightly differently from what we’re used to. In Software Gone Wild Episode 86 Roopa Prabhu and David Ahern explained the fundamentals of packet forwarding on Linux, and the differences between Linux and more traditional...

How Did NETCONF Start on Software Gone Wild

12/2/2017
More
A long while ago Marcel Wiget sent me an interesting email along the lines “I think you should do a Software Gone Wild podcast with Phil Shafer, the granddaddy of NETCONF” Not surprisingly, as we started discovering the history behind NETCONF we quickly figured out that all the API and automation hype being touted these days is nothing new – some engineers have been doing that stuff for almost 20 years.

Ethernet History on Software Gone Wild

10/27/2017
More
During Cisco Live Berlin 2017 Peter Jones (chair of several IEEE task forces) and myself went on a journey through 40 years of Ethernet history (and Token Bus and a few other choice technologies). The sound quality is what you could expect from something recorded on a show floor with pigeons flying around, but I hope you’ll still enjoy our chat. Listen to the podcast

In June 2017, we concluded the Building Next Generation Data Center online course with a roundtable discussion with Andrew Lerner, Research Vice President, Networking, and Simon Richard, Research Director, Data Center Networking @ Gartner. In the second half of our discussion (first half is here) we focused on these topics: Read more ...

Self-Driving Networks with Kireeti Kompella

9/23/2017
More
A while ago I got a kind email from Kireeti Kompella, CTO @ Juniper Networks, saying “A colleague sent me an email of yours regarding SDN, the trough of disillusionment, and the rise of automation. Here's a more dramatic view: the Self-Driving Network -- one whose operation is totally automated.” Even though Software Gone Wild podcast focuses on practical ideas that you could deploy relatively soon in your network, we decided to make an exception and talk about (as one of my friends...

Packet Fabric on Software Gone Wild

6/9/2017
More
Imagine a service provider that allows you to provision 100GE point-to-point circuit between any two of their POPs through a web site and delivers in seconds (assuming you’ve already solved the physical connectivity problem). That’s the whole idea of SDN, right? Only not so many providers got there yet. Read more ...

Start Using OpenConfig with NAPALM on Software Gone Wild

5/26/2017
More
OpenConfig sounds like a great idea, but unfortunately only a few vendors support it, and it doesn’t run on all their platforms, and you need the latest-and-greatest software release. Not exactly a set of conditions that would encourage widespread adoption. Things might change with the OpenConfig data models supported in NAPALM. Imagine you could parse router configurations or show printouts into OpenConfig data structures, or use OpenConfig to configure Cisco IOS routers running a decade...

Snabb Switch with vMX Control Plane on Software Gone Wild

5/18/2017
More
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. Read more ...

Network automation and orchestration is a great idea… but how do you verify that what your automation script wants to do won’t break the network? In Episode 78 of Software Gone Wild we discussed the intricacies of testing network automation solutions with Kristian Larsson (developer of Terastream orchestration softare) and David Barroso of the NAPALM and SDN Internet Router fame.

Ansible, Puppet, Chef, Git, GitLab… the list of tools you can supposedly use to automate your network is endless, and there’s a new kid on the block every few months. In Episode 77 of Software Gone Wild we explored Salt, its internal architecture, and how you can use it with Mircea Ulinic, a happy Salt user/contributor working for Cloudflare, and Seth House, developer @ SaltStack, the company behind Salt.

Programmable ASICs on Software Gone Wild

4/14/2017
More
During Cisco Live Europe 2017 (where I got thanks to the Tech Field Day crew kindly inviting me) I had a nice chat with Peter Jones, principal engineer @ Cisco Systems. We started with a totally tangential discussion on why startups fail, and quickly got back to flexible hardware and why one would want to have it in a switch. Read more ...

NETCONF on Cisco Campus Switches on Software Gone Wild

4/2/2017
More
During Cisco Live Europe (huge thanks to Tech Field Day crew for bringing me there) I had a chat with Jeff McLaughlin about NETCONF support on Cisco IOS XE, in particular on the campus switches. We started with the obvious question “why would someone want to have NETCONF on a campus switch”, continued with “why would you use NETCONF and not REST API”, and diverted into “who loves regular expressions”. Teasing aside, we discussed: Read more ...
