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...

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

Time Is Not On Your Side

It’s been almost five years since I wrote about the challenges of project management and timing your work as an engineer. While most of that information is still very true even today I’ve recently had my own challenges with my son’s Eagle Scout project. He is of a mind that you can throw together a plan and just do a whole week of work in just a couple of days. I, having worked in the IT industry for years, have assured him that it absolutely doesn’t work like that. Why is there a disconnect between us? And how does that disconnect look to the rest of the world?

Time Taking You

The first problem that I often see when working with people that aren’t familiar with projects is that they vastly underestimate the amount of time it takes to get something done. You may recall from my last post that my project managers at my old VAR job had built in something they called Tom Time to every quote. That provided a way for my estimate to reflect reality once I arrived on site and found the things didn’t go according to plan.

Part of the reason why my estimates Continue reading

India reboots plan to attract chip makers to build fabs in country

After initial efforts to attract semiconductor manufacturers to India stumbled, the government is trying again, keeping hopes alive that the country could emerge as a major chip maker at a time when a US-China trade war is transforming the industry and stirring worries about the technology supply chain.This week, after several potential deals fell through, the government is re-inviting applications to a program aimed at developing semiconductor manufacturing facilities and  offering a total subsidy of around $10 billion (Rs 76,000 crore), according to a statement from India’s IT ministry.To read this article in full, please click here

Dynamic data collection with Zaraz Worker Variables

Bringing dynamic data to the server

Dynamic data collection with Zaraz Worker Variables

Since its inception, Cloudflare Zaraz, the server-side third-party manager built for speed, privacy and security, has strived to offer a way for marketers and developers alike to get the data they need to understand their user journeys, without compromising on page performance. Cloudflare Zaraz makes it easy to transition from traditional client-side data collection based on marketing pixels in users’ browsers, to a server-side paradigm that shares events with vendors from the edge.

When implementing data collection on websites or mobile applications, analysts and digital marketers usually first define the set of interactions and attributes they want to measure, formalizing those requirements along technical specifications in a central document (“tagging plan”). Developers will later implement the required code to make those attributes available for the third party manager to pick it up. For instance, an analyst may want to analyze page views based on an internal name instead of the page title or page pathname. They would therefore define an example “page name” attribute that would need to be made available in the context of the page, by the developer. From there, the analyst would configure the tag management system to pick the attribute’s Continue reading

Video: Link State Routing Protocol Basics

After introducing the routing protocols and explaining the basics of link-state routing it was time for implementation considerations including:

  • Collecting local endpoint reachability information
  • Finding neighbors and exchanging the collected information (hint: a link-state topology database is just a distributed key-value store)
  • Running the SPF algorithm (including partial SPF details) and installing the results
