Peter Welcher looks at trends reshaping enterprise and data center networks.
I got tons of questions about the upcoming Building Network Automation Solutions online course. It always starts with the same one:
Is access to the self-study material granted upon enrollment?
Absolutely. You also get access to everything we did in January, and the new self-paced Ansible for Networking Engineers online course.

It’s easy to look at vendor gross margins, and assume that there is plenty of fat. But remember that Gross margin is just Revenue minus cost of goods sold. It’s not profit. It doesn’t include sales & marketing costs, or R&D costs. Those costs affect net income, which is ‘real’ income. Companies need to recoup those costs somehow if they want to make money. Gross margin alone doesn’t pay the bills.
A “four-legged sales call” is when two people show up for sales calls. The usual pattern is an Account Manager for the ‘relationship’ stuff, with a Sales Engineer acting as truth police. These calls can be very useful. It’s a good way to talk about the current business challenges, discuss product roadmaps, provide feedback on what’s working, and what’s not. The Sales Engineer can offer implementation advice, maybe help with some configuration issues.
Often a sales call includes lunch or dinner. Breaking bread together Continue reading

In Information Technology, we commonly hear the mantra of “doing more with less.” That may sound great, and in some cases it can actually be beneficial. It obviously drives the requirement of streamlining performance and the simplification of processes. It can drive innovators to innovate and the attrition of unnecessary systems. The predominate reason for this philosophy is cost cutting.
My argument would generally be that IT should NOT simply be keeping the lights on, it should be adding value by creating competitive differentiators for the business. Being able to execute on that effectively SHOULD change the perspective of IT as it is viewed by the rest of the leadership team. One particular concern I have in regards to those businesses that continue aggressively down this path of cost cutting (or don’t proper initially fund) IT, is in regards to Cybersecurity.
In many cases smaller shops, or shops that don’t fully understand the risks, tend to place their technical team members into split roles. Maybe the view is that someone should be a part-time security person and a part-time network or system administrator. This introduces several concerns and I wanted to quickly share three that are top of mind.
We at Cloudflare strongly believe in network neutrality, the principle that networks should not discriminate against content that passes through them. We’ve previously posted on our views on net neutrality and the role of the FCC here and here.
In May, the FCC took a first step toward revoking bright-line rules it put in place in 2015 to require ISPs to treat all web content equally. The FCC is seeking public comment on its proposal to eliminate the legal underpinning of the 2015 rules, revoking the FCC's authority to implement and enforce net neutrality protections. Public comments are also requested on whether any rules are needed to prevent ISPs from blocking or throttling web traffic, or creating “fast lanes” for some internet traffic.
To raise awareness about the FCC's efforts, July 12th will be “Internet-Wide Day of Action to save Net Neutrality.” Led by the group Battle for the Net, participating websites will show the world what the web would look like without net neutrality by displaying an alert on their homepage. Website users will be encouraged to contact Congress and the FCC in support of net neutrality.
We wanted to make sure our users had an opportunity to participate in this Continue reading
Demonstration of the ESnet research on a research project using intent based networking including an ontological engine for plain english requests. While this is specific to the ESnet requirements there is some really interesting ideas around interpreting user intent and the architecture of an intent-based system.

I love using VIRL to do quick self-check of a config, personal education, and learning the behavior of particular features. I also love using the iTerm2 Terminal Emulator on the Mac. Unfortunately, it isn’t obvious how to make the two play well together. I have had to re-educate myself on this over and over again as I get new computers, mess up my settings and do certain upgrades. I’m pretty sure I copied some of this configuration and the script that I will share from somewhere. So if this looks familiar, reach out to me and I will link back to the source.
This post meant to both share the config and caveats with others as well as to document the nuances for my future reference. In short, there is a standard configuration and a custom configuration for the terminal settings in VIRL’s VMMaestro. These are found in “VMMaestro -> Preferences.”
These settings control whether the built-in (VMMaestro’s client) is used or an external terminal client should be used. I much prefer an external client and iTerm2 is my current client of choice. To eliminate the need of manually launching and connecting, I have customized the Applescript code found below. Continue reading

The July 2017 issue of the IETF Journal is now online at http://www.ietfjournal.org/journal-issues/july-2017/. With IETF 99 in Prague just over one week away, this is the perfect time to get caught up on what's been happening in the world of Internet standards lately.
Global cloud security spend predicted to hit $3.5B by 2021.
