Hedge 243: The Open Radio Area Network (RAN)

The cellular network world is similar enough to the IP networking world to feel familiar, but different enough to require learning new terms and ideas. Tom Nadeau joins Tom Ammon and Russ White to discuss one element of this networking world, the RAN network, and the current move towards open source and white box disaggregated solutions.

When you are designing applications that run across the scale of an entire datacenter and that are comprised of hundreds to thousands of microservices running on countless individual servers and that have to be called within a matter of microseconds to give the illusion of a monolithic application, building fully connected, high bi-section bandwidth Clos networks is a must


The National Institute of Standards and Technology (NIST) just released three finalized standards for post-quantum cryptography (PQC) covering public key encapsulation and two forms of digital signatures. In progress since 2016, this achievement represents a major milestone towards standards development that will keep information on the Internet secure and confidential for many years to come.


Linearity is one of the greatest success stories in mathematics. According to Encyclopedia Britannica, “Unlike other parts of mathematics that are frequently invigorated by new ideas and unsolved problems, linear algebra is very well understood.”


The Turing test could be useful for checking whether a customer service chatbot, for instance, is interacting with people in a way that those people are comfortable with, demonstrating what Jones calls a flexible social intelligence. Whether it can identify more general intelligence, however, is difficult to say.


But in at least some situations, the Supreme Court held this spring in a case called Lindke v. Freed,a it is illegal to block other users. If you are a government official, and you are using social media as part of your job duties, they may have a First Amendment right against being blocked


The recent emergence of generative artificial intelligence and the arrival of assistive agents based on this technology have the potential to offer further assistance to searchers, especially those engaged in complex tasks.


Design and engineering teams increasingly are turning to both classical AI and generative AI to rethink, reinvent, and remake the modern microchip.


In a groundbreaking development for quantum communication, researchers at Qunnect Inc. have successfully achieved the automated distribution of polarization-entangled photons over New York City’s existing fiber network.


The internet is currently controlled through searching, and if Google single-handedly dominates the means through which searching works, then Google effectively controls the internet.

August Rule 11 Academy Update

I’ve been working on new material over at Rule 11 Academy. This month’s posts are:

  • BGP Route Reflector Lab
  • The Clos Fabric (history)
  • The Default Free Zone
  • Network Addresses
  • BGP Policy Entrance Selection (2)
  • Interview Rubric Sample
  • BGP Policy Entrance Select (1)
  • Interviewing Background

    • This brings us up to a total of 39 lessons. Each lesson should be about 15 minutes, so about 10 hours of material so far. The trial membership will take you through the end of the year. After the first of the year, the trial membership will last 2 months.
