Webinars in May 2020
Being stuck at home like most everyone else we’re continuing the increased pace of content production in May 2020:
- I’ll continue the Introduction to Containers and Docker update. We got through the basics the last time and will cover Linux namespaces and how Docker uses them on May 5th.
- We finally found an independent guest speaker familiar with Cisco ACI. Mario Rosi will start the Cisco ACI series with an introductory webinar on May 12th.
- Dinesh Dutt will continue his Network Automation Tools update on May 19th.
- Hoping to get through Introduction to Docker on May 5th, I plan to do a deep dive into Docker Networking on May 26.
- Finally, I’m positive I won’t cover all the bridging and routing material I created in today’s webinar, so we’ll continue with routing protocol basics on May 28th.

Discussion Paper Now Available about the New-IP Proposal
In the run up to the ITU World Telecommunication Standardization Assembly (WTSA-20) later this year there has been some discussion about a proposal called the “New IP.” It is positioned as a top-down architecture to solve a number of use cases that are currently been developed in the ITU-T’s Future Network 2030 Focus Group.
The Internet Society is carefully following the developments in the run-up to WTSA-20. We are trying to understand if and how the New IP works with the Internet as we know it, if it actually solves problems that cannot be solved in the Internet, and, if the ITU-T is developing standards, where other standards development organizations (SDOs) have change control.
In order to get a sense of the environment we commissioned a discussion paper, “An analysis of the ‘New IP’ proposal to the ITU-T.” The paper helps inform us and the broader community whilst the public debate around these proposals shapes up. It also aims to inform and shape the discussion from the Internet’s Society’s perspective. Eventually the debate around it will inform our position and the potential further evolution of the discussion paper itself.
We would like to thank Chip Sharp for authoring the paper, with input Continue reading

Equipment shortages: As schools in the U.S. and other countries attempt to switch over to virtual learning during the COVID-19 pandemic, some are still trying to get students Internet access or devices to use to access the Internet. In Chicago, only about half of the 115,000 public school students who need a computer have received one, WBEZ reports. Another 43,000 computers will be handed out, and 10,000 have been ordered and will be coming “over the next few weeks.”
Equipment shortages, part 2: In California, the state is planning to distribute laptops, Chromebooks, or tablets to more than 70,000 students so they can participate in distance learning, MercuryNews.com reports. The state has requested funding and devices from companies, business leaders and philanthropists around the state.
Getting creative: Some schools are exploring alternatives when students don’t have Internet access or devices, NBC News says. A teacher in Tennessee turned to using a copy machine to print out packets and mail them to students. In Arkansas, where 23 percent of households lack Internet service, a local PBS affiliate is providing daily television programming tied to the state’s distance learning curriculum.

Releasing kubectl support in Access
Starting today, you can use Cloudflare Access and Argo Tunnel to securely manage your Kubernetes cluster with the kubectl command-line tool.
We built this to address one of the edge cases that stopped all of Cloudflare, as well as some of our customers, from disabling the VPN. With this workflow, you can add SSO requirements and a zero-trust model to your Kubernetes management in under 30 minutes.
Once deployed, you can migrate to Cloudflare Access for controlling Kubernetes clusters without disrupting your current kubectl workflow, a lesson we learned the hard way from dogfooding here at Cloudflare.
What is kubectl?
A Kubernetes deployment consists of a cluster that contains nodes, which run the containers, as well as a control plane that can be used to manage those nodes. Central to that control plane is the Kubernetes API server, which interacts with components like the scheduler and manager.
kubectl is the Kubernetes command-line tool that developers can use to interact with that API server. Users run kubectl commands to perform actions like starting and stopping the nodes, or modifying other elements of the control plane.
In most deployments, users connect to a VPN that allows them to run commands against that Continue reading
HS. Part 4. Forging Microsoft SONiC configuration out of the network graph.
Hello my friend,
The visualisation of the network graph is an important part of the network development and management, but we need to move on. Today we will focus on the configuration for Microsoft SONiC running as Docker containers.

Network Automation and Hammer of Thor
Imagine that you just stumbled upon the hammer Thor carelessly dropped, and you’re so proud of your new tool that everything looks like a nail even though it might be a lightbulb or an orange.
That happens to some people when they get the network automation epiphany: all of a sudden CLI and manual configuration should be banned, and everything can be solved by proper incantation of Git and Ansible commands or whatever other workflow you might have set up… even though the particular problem might have nothing to do with what you have just automated.
I’m not saying we should keep using box-by-box CLI for daily operations or mundane configuration tasks. I’m just saying that the world is not as binary as some people want it to be.

MUST READ: When Programming a System with High Kinetic Energy
Kode Vicious (aka George V. Neville-Neil ) wrote another brilliant article on reducing risk in systems that can do serious harm. Here are just two of the gems:
The risks involved in these systems come from three major areas: marketing, accounting, and management.
There is a wealth of literature on safety-critical systems, much of which points in the same direction: toward simplicity. With increasing complexity comes increasing risk …
For whatever reason most networking- and virtualization vendors joined a lemming-like run in the opposite direction years ago.
