EU countries reject plan for big tech companies to fund 5G rollout

Telecom ministers from at least 18 EU countries have rejected a proposal by network operators to have major technology companies fund the rollout of 5G and broadband.The proposal, put forward by telecom lobbying groups GSMA and ETNO, which represent 160 operators across Europe, says that big tech companies that account for more than 5% of a provider’s peak average internet traffic should help foot the bill for rolling out the services across Europe.The EU launched a consultation on the issue in February 2022. According to a report by Reuters, telecom ministers met with EU Commissioner Thierry Breton to raise their objections, with those who are against the proposal saying there is a lack of analysis to prove the measure would actually work, with some citing concerns that tech companies would end up passing these costs onto the consumer.To read this article in full, please click here

Nine years of Project Galileo and how the last year has changed it

Nine years of Project Galileo and how the last year has changed it
Nine years of Project Galileo and how the last year has changed it

If you follow Cloudflare, you know that Birthday Week is a big deal. We’ve taken a similar approach to Project Galileo since its founding in 2014. For the anniversary, we typically give an overview of what we have learned to protect the most vulnerable in the last year and announce new product features, partnerships, and how we’ve been able to expand the project.

When our Cloudflare Impact team was preparing for the anniversary, we noticed a theme. Many of the projects we worked on throughout the year involved Project Galileo. From access to new products, development of privacy-enhancing technologies, collaborations with civil society and governments, we saw that the project played a role in either facilitating conversation with the right people or bridging gaps.

After reflecting on the last year, we’ve seen a project that was initially intended to keep journalism and media sites online grew into more. So, for this year, in addition to new announcements, we want to take the time to reflect on how we have seen Project Galileo transform and how we look toward the future in protecting the most vulnerable on the Internet.

The original goal of Project Galileo was simple. Although Continue reading

How IT pros might learn to believe in AI-driven network-management

IT organizations that apply artificial intelligence and machine learning (AI/ML) technology to network management are finding that AI/ML can make mistakes, but most organizations believe that AI-driven network management will improve their network operations.To realize these benefits, network managers must find a way to trust these AI solutions despite their foibles. Explainable AI tools could hold the key.A survey finds network engineers are skeptical. In an Enterprise Management Associates (EMA) survey of 250 IT professionals who use AI/ML technology for network management, 96% said those solutions have produced false or mistaken insights and recommendations. Nearly 65% described these mistakes as somewhat to very rare, according to the recent EMA report “AI-Driven Networks: Leveling Up Network Management.” Overall, 44% percent of respondents said they have strong trust in their AI-driven network-management tools, and another 42% slightly trust these tools.To read this article in full, please click here

Default EBGP Policy (RFC 8212)

One of the most common causes of Internet routing leaks is an undereducated end-customer configuring EBGP sessions with two (or more) upstream ISPs.

Without basic-level BGP knowledge or further guidance from the service providers, the customer network engineer1 might start a BGP routing process and configure two EBGP sessions, similar to the following industry-standard CLI2 configuration:

RIPE 86 Bites – Encryption and Active Network Management

RIPE held a community meeting in May in Rotterdam. There were a number of presentations that sparked my interest, but rather than write my impressions in a single lengthy note, I thought I would just take a couple of topics and use a shorter, and hopefully more readable bite-sized format. Here’s the third of these bite-sized notes from the RIPE 86 meeting, on the topic of the implications of an encrypted content on active network management.

Back to Basics: A Primer on Communication Fundamentals

Motivation

In our rapidly advancing world, communication speeds are increasing at a fast pace. Transceiver speeds have evolved from 100G to 400G, 800G, and soon even 1.6T. Similarly, Optical systems are evolving to keep up with the pace. If we dig deeper, we will discover that many concepts are shared across various domains, such as Wi-Fi, optical communications, transceivers, etc. Still, without the necessary background, It’s not easy to identify the patterns. If we have the essential knowledge, it becomes easier to understand the developments happening in the respective areas, and we can better understand the trade-offs made by the designers while designing a particular system. And that’s the motivation behind writing this post is to cover fundamental concepts which form the basis for our modern communication system and how they all relate to each other.

Waves

So let’s start with the most fundamental thing, i.e., wave. A wave is a disturbance that carries energy from one location to another without displacing matter. Waves transfer energy from their source and do not cause any permanent displacement of matter in the medium they pass through. The following animation demonstrates this concept.

Data center developers turn to emerging US markets

Data center developers are under pressure to expand their horizons when it comes to choosing sites for new construction. Land prices, availability of power and bandwidth, and pushbacks from neighbors are among the factors that are driving developers to seek new regions.Northern Virginia, for example, is home to more data centers than any other part of the world, with 275 and more on the way. But the region is running out of space and available power, and residents are running out of patience for these resource-intensive facilities that consume growing amounts of power and water, according to the Washington Post. To read this article in full, please click here
