Whatever is vOLT-HA?

Many network engineers find the entire world of telecom to be confusing—especially as papers are peppered with a lot of acronyms. If any part of the networking world is more obsessed with acronyms than any other, the telecom world, where the traditional phone line, subscriber access, and network engineering collide, reigns as the “king of the hill.”

Recently, while looking at some documentation for the CORD project, which stands for Central Office Rearchitected as a Data Center, I ran across an acronym I had not seen before—vOLT-HA. An acronym with a dash in the middle—impressive! But what is, exactly? To get there, we must begin in the beginning, with a PON.

There are two kinds of optical networks in the world, Active Optical Networks (AONs), and Passive Optical Networks (PONs). The primary difference between the two is whether the optical gear used to build the network amplifies (or even electronically rebuilds, or repeats) the optical signal as it passes through. In AONs, optical signals are amplified, while ins PONs, optical signals are not amplified. This means that in a PON, the optical equipment can be said to be passive, in that it does not modify the optical signal in Continue reading

The Week in Internet News: AI Could Reshape the Music Industry, in a Good Way

AI Hits the Right Notes: Artificial intelligence-generated music is reshaping the industry, but that’s not such a bad thing, notes Billboard.com. AI won’t replace the artists we love or end creativity, but it could empower creators with new songwriting and other tools, the story suggests.

Drilling for AI: Oil producers are also turning to AI to help them with several tasks, according to an interview with oil executive Philippe Herve of SparkCongnition, published in Houston’s Chron.com. AI can assist oil producers with predictive maintenance of their expensive field equipment and help them make sense of all the data they collect, he said.

Collateral damage for app ban: Russia has attempted to shut down messaging app Telegram, after the service refused to provide authorities encryption keys to its software. It’s not going so well, however. Russian’s attempts to block the app have inadvertently knocked out a bunch of small business websites in the country, reports the New York Times. Telegram attempted to get around the ban by shifting its service to U.S. Web hosts Google Cloud and Amazon Web Services, while repeatedly changing its IP address. In response, Russia shut down huge blocks of subnets instead of trying Continue reading

Vexata Has Its Own Twist On Scaling Flash Storage

When looking for all-flash storage arrays, there is no lack of options. Small businesses and hyperscalers alike helped fuel the initial uptake of flash storage several years ago, and since then larger businesses have taken the plunge to help drive savings in such areas as power and cooling costs, floor and rack space, and software licensing.

The increasing demand for the technology – see the rapid growth of Pure Storage, the original flash array upstart over the past nine years – has not only fueled the rise of smaller vendors but also the portfolio expansion of such established …

Strategy: Use TensorFlow.js in the Browser to Reduce Server Costs

 

One of the strategies Jacob Richter describes (How we built a big data platform on AWS for 100 users for under $2 a month) in his relentless drive to lower AWS costs is moving ML from the server to the client.

Moving work to the client is a time honored way of saving on server side costs. Not long ago it might have seemed like moving ML to the browser would be an insane thing to do. What was crazy yesterday often becomes standard practice today, especially when it works, especially when it saves money:

Our post-processing machine learning models are mostly K-means clustering models to identify outliers. As a further step to reduce our costs, we are now running those models on the client side using TensorFlow.js instead of using an autoscaling EC2 container. While this was only a small change using the same code, it resulted in a proportionally massive cost reduction. 

To learn more Alexis Perrier has a good article on Tensorflow with Javascript Brings Deep Learning to the Browser:

Tensorflow.js has four layers: The WebGL API for GPU-supported numerical operations, the web browser for user interactions, and two APIs: Continue reading

Network Break 181: Russia Accused Of Infrastructure Attacks; US Targets ZTE

Take a Network Break! The US and British governments have accused Russian state actors of compromising routers and other network infrastructure, the United States forbids American companies from selling components to Chinese telecom firm ZTE, and Huawei rethinks its US strategy.

Cisco releases notes on its 9500 switches and UADP silicon, IBM releases a mainframe that takes the same space as a traditional 19-inch server rack, and VMware shares rise on rumors that Dell won’t reverse-merge with it.

Arista’s share price stumbles, and then recovers; Cisco ditches the Spark brand name; a Cisco security exec says we’re all screwed; and the United States is the leading source of botnet attacks in the world.

5 key enterprise IoT security recommendations

Not so long ago, the phrase “consumerization of IT” was on everyone’s lips. Whole publications and conferences (remember CITE, for Consumerization of IT in the Enterprise?) were created to chronicle the trend of corporations relying on products and services originally created for consumers — which was often easier to use and of higher quality than its business-oriented competitors.Well, no one talks much about the consumerization of IT anymore… not because the trend went away, but because consumer tech has now permeated every aspect of business technology. Today, it’s just how things work — and if you ask me, that’s a good thing.To read this article in full, please click here

– Intro on how Devops got introduced
– what needs to be improved – Key Idea “No More Silos”
– stress on non-localization of knowledge, lack of collaboration
– New Job Role called SRE – Site Reliability Engineering
– Operations is a Software problem and Work to minimize Toil are some best examples of productivity and how we should view

Introducing a New MANRS IXP Programme for Routing Security

Today, we are pleased to announce that the Mutually Agreed Norms for Routing Security (MANRS) is getting a new category of members – IXPs. The MANRS IXP Programme introduces a separate membership category for IXPs with a set of security actions to address the unique needs and concerns of IXPs.
The ten founding participants are Asteroid (International), CABASE (Argentina), CRIX (Costa Rica), DE-CIX (Germany), INEX (Ireland), MSK-IX (Russia), Netnod (Sweden), RINEX (Rwanda), TorIX (Canada), and YYCIX (Canada).
Programme participation provides an opportunity for an IXP to demonstrate its attention to the security and sustainability of the Internet ecosystem and, therefore, its dedication to providing high-quality services.
The IXP Action set was developed by a group of IXPs from all around the world and was presented at multiple IXP fora for discussion and feedback. We hope that with IXPs as partners, their ISP members will also join the Network Operator category of MANRS.
Participation in the MANRS IXP Programme requires an IXP to implement and document a majority of the IXP Programme Actions (at least three out of five). Actions 1 and 2 are mandatory, and the IXP must implement at least one additional Action. Here are the five Actions:
  1. Facilitate Continue reading

A more privacy-friendy blog

When I started this blog, I embraced some free services, like Disqus or Google Analytics. These services are quite invasive for users’ privacy. Over the years, I have tried to correct this to reach a point where I do not rely on any “privacy-hostile” services.

Analytics?

Google Analytics is an ubiquitous solution to get a powerful analytics solution for free. It’s also a great way to provide data about your visitors to Google—also for free. There are self-hosted solutions like Matomo—previously Piwik.

I opted for a simpler solution: no analytics. It also enables me to think that my blog attracts thousands of visitors every day.

Fonts?

Google Fonts is a very popular font library and hosting service, which relies on the generic Google Privacy Policy. The google-webfonts-helper service makes it easy to self-host any font from Google Fonts. Moreover, with help from pyftsubset, I include only the characters used in this blog. The font files are lighter and more complete: no problem spelling “Antonín Dvořák”.
