How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

Cisco Introduces Intent-Based Network That Can Learn, Adapt and Mitigate Threats

Major New Funding Opportunities for Internet Researchers and R&E Networks

Nationally Appropriate Mitigation Action (NAMA) is a new policy program that was developed at the Bali United Nations Climate Change Conference. As opposed to the much maligned programs like CDM and other initiatives NAMA refers to a set of policies and actions that developed and developing countries undertake as part of a commitment to reduce greenhouse gas emissions. Also unlike CDM, NAMA recipients are not restricted to developing countries. more

Iran Among Countries Affected by a Cyberattack That Left U.S. Flag on Screens

Keep Your Pants On: Governments Want Suspenders for Secure Routing

The difficulty of applying a hierarchically organized PKI to the decentralized world of Internet routing is being fully exposed in a new Internet-draft. The document represents a rational response to an RPKI that closely ties address resources to a handful of Internet governance institutions, nicely illustrates how governments and national security policy are influencing Internet security, and portends substantial costs for network operators and beyond if adopted widely more

Obama to Sign Executive Order for Streamlining Approval of Internet Networks

Currently, the process for approving broadband construction projects on federal property varies from agency to agency. Property controlled by the federal government includes roads, about 30 percent of the nation's land and more than 10,000 buildings. The order will require the Departments of Agriculture, Commerce, Defense, Interior, Transportation and Veterans Affairs as well as the Postal Service to develop a single process for approving Internet construction projects. more

A Note to PhDs Transferring From Academia to the ML Industry

Congratulations. You have successfully defended your PhD dissertation, and it was a defining moment in your life. Your professorial experience and teaching assistant credentials are finally going to pay off. Further, you might have hundreds of citations, and PhDs are sought after because of their subject matter expertise. Well, that is OK. All that hard work and discipline allows you to use your newly earned moniker and seek out additional opportunities, either within the scope of academia or corporate options. Wait, Wait, Wait, not so fast. If you are thinking of just strolling into the industry and immediately begin earning a six-figure salary, think again, my friend. more

Software Has Already Eaten Telecoms (It Just Has Indigestion)

The unconscious and near-universal belief is that packet networks are a telecoms service, and one that constructs an 'additive' resource called 'bandwidth'. This is demonstrably technically false. They deliver distributed computing services, as they calculate how to divide up an underlying telecoms transmission resource. The ubiquitous error is a failure to recognise that the hardware platform has already been devoured by the software industry. more

The Magical Ampersand: Hope Is Not an Integration Plan

In a software-defined and virtualised world, who will integrate the complex dynamic systems, and take responsibility for the result? It is unclear if telcos have the skills, but someone else likely does... The included image caught my eye whilst I was reviewing presentations from last October's Metro Ethernet Forum gathering in Florida on behalf of a consulting client. At first glance, it's just a marketing pseudo-Venn diagram peppered with telco tech buzzword bingo. But... more

North Korea Suffers Internet Outage, U.S. Blamed

According to reports, North Korea has accused the United States for conducting a cyberattack that has disrupted Internet connectivity in the country. "While the details of the cause of the disruption are unknown, we can confirm that in the last two days, North Korea's sole Internet provider has, in fact, suffered from disruptions in connectivity to the global Internet," reports Doug Madory from Renesys. more

The Internet of the Future – What Happens Behind the Scenes?

Today's Internet is a critical infrastructural element whose continued development influences industries, cultures, and the private space of most individuals. However, the world-encompassing network sometimes needs to be adapted to new requirements to keep pace with current innovations. We have recently seen accelerating development of Internet usage on the user side. Whether it is online shopping's expansion or the greater distribution of mobile devices or streaming services... more

Network Outages Costing Mobile Operators $15B Annually

Sarah Reedy reporting in LightRading: Mobile operators suffer from an average of five network outages or degradations that impact subscribers each year, costing them around $15 billion annually, according to new Heavy Reading research. Put another way, that's about one outage every other month. More than 80 percent of those outages affect just one or a subset of networks or services. more

Prime Real Estate in the Cloud

In the physical world of real estate, value is all about location, location, location. In the virtual world of enterprise business, value is all about performance. The catch is that enterprise performance today is often driven by... location, location, location. When it comes to your digital transformation, and the migration of services to the cloud, the location of your data is paramount. To reach a customer looking to complete an on-line purchase or enable a group of employees trying to collaborate on a shared document, data needs... more

Holding Times – A Phenomenon Happening With ISP Networks That No One Seems to Talk About

During the last year, we saw a big change in the nature of our broadband usage in that many of us are connecting to remote work or school servers, or we are connecting to long Zoom calls. We already can see that these changes have accelerated the average home usage of broadband. OpenSignal reports that the average broadband usage per home grew from 274 gigabytes per month just before the pandemic up to 462 gigabytes per month measured at the end of the first quarter of this year. more
