This document presents an architecture called the mini-fiber node (mFN) technology that was being tested by AT&T Broadband and AT&T Labs to address bandwidth demands on cable networks. It describes the initial mFN architecture using fiber to the mFN and passive coaxial cable between the mFN and subscribers. It also outlines challenges with current networks and proposes a migration path to a new integrated platform using muxnodes and mFNs to reduce active components and power consumption while supporting current and future services. Finally, it provides an update on an mFN field trial underway in Salt Lake City to evaluate cost savings and operation benefits.

As part of our over-the-top experiment, this was the business proposal and design for digitizing Zhengzhou Cable (China) and establishing a value-added-service-operator (VASO) in China

iBIT was incubated by Morning Forest back in 2002 and had a wholly owned subsidiary in China for this experiment.
Cathy Wilson, founder and publisher of Broadband Library International initiated a project to report how Japan cable industry recovers from the disaster and the lessons that could benefit cable industry worldwide. I was fortunately involved.
Historically, cable industry was isolated and had the mindset of old-boy club. Cross industry collaboration was rare (although HFC network technology has been the most beautiful collaborative innovation between cable and telecom industries). In our research of Japan cable industry recovery, we are pleased to find out that the industry heavily leveraged other industries’ innovations and also collaborated closely among themselves in overcoming the challenges - the industry is growing up.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
