Video: Kubernetes Calico Plugin
November is turning out to be the Month of BGP on my blog. Keeping in line with that theme, let’s watch Stuart Charlton explain the Calico plugin (which can use BGP to advertise the container networking prefixes to the outside world) in the Kubernetes Networking Deep Dive webinar.

Intelligent spaces technology provides important data points that can make a significant difference in the work environment for all employees—and keep them wanting to return to the office.The Bottom Line on Upcoming Non-Terrestrial Network (NTN) Services
Are the latest NTN developments, led by the FCC and LEO bird owners, milestones on the road to broadened use of satellite services by Enterprise IT?SPCOR Exam Experience by Nick Russo
On 31 October 2023, I took and passed the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) exam on my first attempt. Most of you know that I am recognized as an expert on Cisco Service Provider technologies given that I was one of the first to pass the new CCIE SPv4 exam in early 2016. Three months later, I released book of nearly 3,000 pages detailing all the technologies involved in that blueprint, going extremely deep into every topic. I later partnered with two other Service Provider experts to sell an ultimate study bundle that combined my textbook with their lab workbook. I think it’s fair to say that I should have crushed this exam, and although I did pass, it was far more difficult than I anticipated.
A few years ago, I also took the SCOR exam, but didn’t write a blog about it because I felt the exam was unremarkable. My friend Craig Stansbury has an excellent SCOR learning path at Pluralsight that I used to pass the exam on the first try, but on balance, it felt like a regular CCNP exam. SPCOR was a whole new class of difficulty. When I Continue reading
How We Measure: RPKI ROA Signing and Route Origination Validation
t APNIC Labs we publish a number of measurements of the deployment of various technologies that are being adopted on the Internet. Here we will look at how we measure the adoption of the signing of Route Origination Attestations (ROAs) as part of the framework for securing inter-domain routing on the Internet using the digital credential framework provided by the Resource Public Key Infrastructure (RPKI).How We Measure: DNSSEC Validation

What if you could have a multi-cloud network that was cloud-native, but you didn’t have to know the nitty-gritty details for each of the clouds? That is, you work with a single cloud network interface, and that platform handles the networking so you can focus on things like improving the velocity of application rollouts, architecture, security, and efficiency? Sponsor Prosimo says its platform can do this. On today's show we look under hood to get details on its multi-cloud networking platform.

That is, you work with a cloud network interface, and that platform handles the networking–in a cloud-native way–for you. You wouldn’t need to know the nuances of AWS, Azure, and...

A while ago, the Networking Notes blog published a link to my “Will Network Devices Reject BGP Sessions from Unknown Sources?” blog post with a hint: use Shodan to find how many BGP routers accept a TCP session from anyone on the Internet.
The results are appalling: you can open a TCP session on port 179 with over 3 million IP addresses.

AI Is Making Data Cost Too Much
You may recall that I wrote a piece almost six years ago comparing big data to nuclear power. Part of the purpose of that piece was to knock the wind out of the “data is oil” comparisons that were so popular. Today’s landscape is totally different now thanks to the shifts that the IT industry has undergone in the past few years. I now believe that AI is going to cause a massive amount of wealth transfer away from the AI companies and cause startup economics to shift.
Can AI Really Work for Enterprises?
In this episode of Packet Pushers, Greg Ferro and Brad Casemore debate a lot of topics around the future of networking. One of the things that Brad brought up that Greg pointed out is that data being used for AI algorithm training is being stored in the cloud. That massive amount of data is sitting there waiting to be used between training runs and it’s costing some AI startups a fortune in cloud costs.
AI algorithms need to be trained to be useful. When someone uses ChatGPT to write a term paper or ask nonsensical questions you’re using the output of the GPT training run. Continue reading
