Automating your network can seem like a daunting task. But the truth is that automating Cumulus Linux with Ansible can be easier than many of the things you’re probably already automating.
In this post, I’ll show you how to get started on your network automation journey using a simple, four-step process:
To illustrate, I’ll be using the following simple, bare-bones topology based on the Cumulus Reference topology. You can follow along by spinning up your own virtual data center for free using Cumulus in the Cloud.
The first step is to pick one thing to automate. Just one! The only caveat is that it needs to be something you understand and are comfortable with. Trying to automate a feature you’ve never used is sure to scare you away from automation forever, unless of course you have someone guiding you through the process.
Preferably, pick something that’s quick and simple when done manually. Configuring the OSPF routing protocol between two switches falls into this category. When done manually, Continue reading
Security researchers tied the malware to a Russian group responsible for hacking incidents during the 2016 U.S. presidential campaign.
Newly released SDxCentral 2018 report on the VNF Ecosystem finds SD-WAN and vCPE are top use cases for NFV and the driving force behind service providers virtualizing their networks.
Many companies are looking at ways to accelerate their SDN adoption so they don’t risk falling behind.
Dustin Phillips, Co-Executive Director of ICANNWiki, is traveling across the United States in his red Toyota Corolla, making connections with the people who are making their communities – and the Internet – a better place. He visited the Bay Area, first making a stop at the Redwood National and State Parks, where he learned about redwood communities and how their survival is dependent on interconnection, a metaphor for the Internet itself.
What is the Internet Ecosystem?
The Internet affects nearly every aspect of society, creating an extremely wide range of stakeholders. There is still a community of stakeholders engaged directly with the Internet’s policymaking processes, but increasingly there are Internet-related discussions occurring at what would traditionally be considered unlikely venues.
CITRIS and the Banatao Institute
Meeting with Dr. Brandie Nonnecke at the University of California, Berkley’s Center for Information Technology Research in the Interest of Society (CITRIS) and the Banatao Institute was a fitting way to kick off my time in the Bay Area. We had a great discussion on the important role of civic participation and collaborative processes for informed decision-making in key issue areas.
Like the incredibly diverse plant life that grows in the understory Continue reading
This is a short article on creating a self-signed root certificate which can be used to self-sign certificates for the purposes of treating our telemetry and instrumentation exploration with the security love it deserves. I also cover configuration of mutual SSL for gRPC on Junos. An article of dual purposes!
One of the things I see far too often is clear-text transport being used in demonstrations, labs and even production. This isn’t acceptable. We live in a world where security has to be woven in from the ground up. How do you really know your system works if you leave out all of the security controls?
I hear your teeth grinding. Why do you want to do this? First of all, even though we can bypass security on gRPC with Junos by going for insecure connectivity with clear-text, we shouldn’t. The world we live in is all about the data and the smallest amount of it can give the ‘bad guys’ a lead.
Now we’re done with the why, we need to deal with the how. There are three approaches to PKI that are common:
We often treat security as an absolute, “that which must be done, and done perfectly, or is of no value at all.” It’s time to take this myth head on, and think about how we should really think about security.
The software is targeted at large-scale enterprises looking to make the jump from legacy or proprietary systems like those from Cisco.
AT&T rebranded its AIC. And 5G will be the first new use case to run on its evolved network cloud.
It turns out you can t do it all in the cloud. And thus, we have the rise of edge computing, in which data is collected, processed, and analyzed close to the source of its creation and close to where people and systems need it.
The goals of edge computing include improving performance, reducing the costs and time of data transmission, and creating new applications to take advantage of that data.
Our guide to edge computing is Alex Marcham. Alex is a technologist, writer and researcher. You can find his work at NetworkArchitecture2020.com.
We level-set with a working definition of edge computing, examine the notion of locality and what it means for edge computing, and discuss latency issues.
We explore edge computing use cases such as industrial processes and video surveillance, and dive into the infrastructure that drives this technology.

On May 14, a group of young people who are currently working on or are studying tech, politics, computer science, and the Internet of Things (IoT) met for a two-hour Youth Advocates for IoT Security round table. This event was a part of the Internet Society’s year-long initiative, the Canadian Multistakeholder Process – Enhancing IoT Security in partnership with Innovation, Science and Economic Development, the Canadian Internet Registration Authority, CANARIE, and CIPPIC. It serves as just one of several workshops that will be held during the process to develop recommendations for a set of norms and policies to secure the IoT in Canada.
The round table offered an opportunity for young people in school or their early careers to voice their opinions and provide unique inputs for consideration on the following aspects of IoT security:
The group discussed the ways in which IoT devices have become seemingly ubiquitous in youth’s lives. IoT devices have also become integral, and often required, parts of classroom learning and workplaces. Now, the lines Continue reading
