Based on what we know about Space Networks like Starlink, I propose that next generation cars won't use 5G. Its doesn't make sense to deal with telcos.

Call it “trickle-down networking” if you like. But what has long been possible—and even best practice— in data center networking is now moving aggressively into and onto campus networking ecosystems. And with that move companies and organizations can realize numerous benefits in or on the campus networks they own or operate. As readers peruse this list of potential benisons, they’ll undoubtedly hit hot buttons with their users (thanks to increased features and functionality) and with management (thanks to cost savings and improved efficiencies that reduce staff time commitments and involvement).
With the adoption of data center tools and technologies in campus networks, a handful of key capabilities becomes available throughout. These include Power over Ethernet (PoE), which makes it possible to extend services more easily and affordably, and to integrate Internet of Things (IoT) capabilities more directly (such as sensors, surveillance cameras, ID badge readers and so forth). In addition, networks gain ready access to 802.1X capabilities when they adopt a data center model, including improved and more powerful authentication mechanisms, as well as access and security control.
Moving to data center-oriented networks usually also brings voice VLANs into the networking picture. This not only offers Continue reading

Crypto-regulation: A new law in China regulates the use of encryption, but it’s aimed at strengthening it, at least in some settings, Reuters reports. The law is aimed at aiding the development of a digital currency in China, and it is focused on “facilitating the development of the cryptography business and ensuring the security of cyberspace and information,” according to the official Xinhua news agency said. The law also that all state secrets be stored and transmitted using “core and common” encryption, Engadget says.
Build your own: Some rural Colorado communities are tired of waiting for large broadband providers to bring them service and are seeking grants or forming partnerships to build their own networks, the Canon City Daily Record says. Grants from the state at the Federal Communications Commission are helping communities build fiber networks.
Not so secure: Wyze Labs, the maker of a line of IoT-connected security cameras, has announced a data breach affecting 2.4 million customers. The breach included WiFi network details and customer email addresses, Salon reports. The security cameras don’t appear to be compromised, but compromised email addresses can lead to further customer data breaches, the story notes. Also, there’s this: “The blog Twelve Security Continue reading
A year ago I wrote about ipSpace.net plans for 2019. While we created over 50 hours of webinar content and over 20 hours of course content in 2019, let’s see how well we delivered on my promises.
Following AWS Networking webinar, we’ll do a similar one on Azure (in early autumn 2019) and GCP (late 2019 or early 2020)
Azure: done. GCP: postponed. Let’s see how serious Google is about that particular project.
Read more ...Welcome to another year of The Morning Paper! Over the holidays I spent
some time mapping out a partial conference calendar for the year, and thinking about the kinds of papers I want to be reading. In a typical year, I’ll cover somewhere north of 120 papers on this blog. That’s a tiny drop in the ocean compared to the amount of research published. And then as well as dipping my toes into the new, I also want to make more space for papers that have stood the test of time. Following the Lindy effect these are the ones most likely to continue giving ten years or more into the future. Where have we come from? Where are we now? And where are we heading? My only firm rule for paper selection is that I must find it interesting. As regular readers of The Morning Paper will know though, my interests are pretty broad and will no doubt take many twists and turns over the course of the year.
Through the course of a year I often have the pleasure of bumping into many readers of The Morning Paper. And very often they tell me apologetically that they don’t always Continue reading

Dear friend,
I hope you have a relaxing holiday period and now you are ready to kick off the new year. For us year has already started 2 days ago…
… With announcement that our blog is chosen to be Cisco Champion in 2020. We are very delightful to be a Cisco Champion two times in a row (2019 and 2020). Thank you very much for supporting us, for your interest and your questions.
The good news for you is that the application is yet opened for a couple of days, so you can try to apply yourself.
If you even more interested in your future, join our network automation training we start on 18th and 22nd of January, where we cover the details of the data modelling, NETCONF/YANG, REST API, Python and Ansible in the multivendor environment with Cisco, Nokia, Arista and Cumulus Linux as network functions.
I tend to assess automation tools in four different contexts which is, in fact, a very general networking and automation workflow: Discovery How easy is it to find out about the network, document its configuration (the configuration of a device itself) and state (show commands "snapshotting" its state)? Configuration Creation How easy is it to READ MORE

nornir (formerly brigade) - A new network automation framework Before getting started, let me say that I'm big fan of Ansible. It is one of my go-to automation frameworks. Having said that, there have been use cases where I've run into some of the limitations of Ansible and to be fair some of those limitations may READ MORE

We have exciting news: Cloudflare closed out the decade by reaching our 200th city* across 90+ countries. Each new location increases the security, performance, and reliability of the 20-million-plus Internet properties on our network. Over the last quarter, we turned up seven data centers spanning from Chattogram, Bangladesh all the way to the Hawaiian Islands:
A long while ago someone told me about a "great" idea of using multi-port server NICs to build ad-hoc (or hypercube or whatever) server-only networks. It's pretty easy to prove that the approach doesn't make sense if you try to build generic any-to-any-connectivity infrastructure... but it makes perfect sense in a small environment.
One can only hope Scale Computing keeps their marketing closer to reality than some major vendors (that I will not name because I'm sick-and-tired of emails from their employees telling me how I'm unjustly picking on the stupidities their marketing is evangelizing) and will not start selling this approach as save-the-world panacea... but we can be pretty sure there will be people out there using it in way-too-large environments, and then blame everything else but their own ignorance or stubbornness when the whole thing explodes into their faces.
