Episode 3 – The Unique Challenges of Working in SMB
In this episode of Network Collective we dive in to the challenges of working as a technologist in a small or medium sized business (SMB). We look at things like staffing, budgets, and small business mindsets that make working in this space very different than working in mid-market or enterprise organizations. Matt Haedo, John Duprey, and Kevin Blackburn join the Network Collective hosts in talking about this common, but often under the radar topic.

Failure Is Inevitable – Deal with It!
Last week a large European financial institution had a bad hair day. My friend Christoph Jaggi asked for my opinion, and I decided not to focus on the specific problem (that’s what post-mortems are for) but to point out something that’s often forgotten: don’t believe your system won’t fail, be prepared to deal with the failure.
Time to Overhaul Your Campus Network
Over the last few years cloud service providers have steadily adopted white-box Ethernet switches and modern, flexible Network Operating Systems into their ecosystems. Mega data center operators, such as Google, Amazon, and Microsoft, have replaced their proprietary gear with white boxes in their production environments. The major benefit of this paradigm shift is significantly reduced CapEx and OpEx, a more reliable environment, and customized traffic flows for efficiency. According to IDC, the worldwide ODM direct Ethernet switch (white box) market was $677 million in 2016 and is expected to exceed $900 million in 2017. That’s a growth rate of 33%, and the trend is accelerating.
The shift in white-box adoption started as early as 2012, but has been limited to data centers for many reasons. Even though Enterprise IT executives are motivated to adopt white-boxes, the migration has been slow and challenging. Essentially, the Enterprise network is distinctly different from data center network in many ways.
- The data center network is usually homogeneous, while the Enterprise network is heterogeneous. Typically, Enterprises require a variety of speeds ranging from 100Mbps to 100Gbps, and run over different cables, including various types of copper and fiber. The increasingly deployed Power over Ethernet (PoE) Continue reading

Open vSwitch Day at OpenStack Summit 2017
This is a “liveblog” (not quite live, but you get the idea) of the Open vSwitch Open Source Day happening at the OpenStack Summit in Boston. Summaries of each of the presentations are included below.
Kubernetes and OVN on Windows
The first session was led by Cloudbase Solutions, a company out of Italy that has been heavily involved in porting OVS to Windows with Hyper-V. The first part of the session focused on bringing attendees up to speed on the current state of OVS and OVN on Hyper-V. Feature parity and user interface parity between OVS/OVN on Hyper-V is really close to OVS/OVN on Linux, which should make it easier for Linux sysadmins to use OVS/OVN on Hyper-V as well.
The second part of the session showed using OVN under Kubernetes to provide networking between Windows containers on Windows hosts and Linux containers on Linux hosts, including networking across multiple cloud providers.
Lightning Talks
The lightning talks were all under 5 minutes, so a brief summary of these are provided below:
- Joe Stringer showed how to set up OVS with an OpenFlow controller (Faucet) to do networking between multiple hosts in 5 minutes or less.
- A gentleman (I didn’t catch Continue reading
