Complexity and Crashes

It's a familiar story by now: on the 8th of August, 2016, Delta lost power to its Atlanta data center, causing the entire data center to fail. Thousands of flights were cancelled, many more delayed, and tens of thousands of travellers stranded. What's so unusual about this event is in the larger scheme of network engineering, it's not that unusual. If I think back to my time on the Escalation Team at a large vendor, I can think of hundreds of situations like this. And among all those events, there is one point in common: it takes longer to boot the system than it does to fix the initial problem. more

Ailing ETO-2002 and the Demise of PKI

The only Cyber law passed in Pakistan till date is the famous ETO-2002 (Electronic Transaction Ordinance - 2002). It required Ministry of IT&T to set up a Central Repository for all digital certificates and in addition to set up a body to be named as Electronic Certification Accreditation Council (ECAC) to accredit Electronic Certification Authorities to be established in the country... In this regard, government has not only closed its eyes and has blindly trusted the only certificate authority (CA) in the country operated by a private business group, it has also mandated the citizens and business to trust it. Case in point is Central Board of Revenue (CBR) that has told all taxpayers to digitally sign the emails using the certificates issued by this private party... more

Building a “Domain of Trust” - Protecting Online Identity in the Age of AI and 6G

In today's interconnected world, your business's online identity is increasingly more vulnerable than ever. With the rapid advancement of AI and 6G technologies, cyber threats are evolving at an alarming rate, making it critical to protect your brand's digital presence. How can businesses proactively safeguard their online identity in this changing landscape?  more

The Strength of Top-Level Domains in UDRP Decisions

Another domain name dispute decision -- this one for '24hour.fitness' -- has highlighted the increasing (potential) relevance of the top-level domain (TLD) under the Uniform Domain Name Dispute Resolution Policy (UDRP). As I have written before, the proliferation of new TLDs is having an impact on whether and how UDRP panels consider the TLD in their decisions. more

The Future of Networking (In One Slide)

I recently ran a workshop in Asia and to guide attendees through the content; I put together an overview slide which you might also find of interest and use. It is a description of the quality attenuation framework, originally developed and defined by Predictable Network Solutions Ltd, and documented and extended by myself and colleagues at Just Right Networks Ltd. more

Networks Are Not Cars Nor Cell Phones

The network engineering world has long emphasized the longevity of the hardware we buy; I have sat through many vendor presentations where the salesman says "this feature set makes our product future proof! ... Over at the Networking Nerd, Tom has an article posted supporting this view of networking equipment, entitled Network Longevity: Think Car, not iPhone. It seems, to me, that these concepts of longevity have the entire situation precisely backward. more

Can Large Language Models Use the Contents of Your Website?

Large Language Models (LLM) like GPT -- 4 and its front-end ChatGPT work by ingesting gigantic amounts of text from the Internet to train the model and then responding to prompts with text generated from those models. Depending on who you ask, this is either one step (or maybe no steps) from Artificial General Intelligence, or as Ted Chiang wrote in the New Yorker, ChatGPT Is a Blurry JPEG of the Web. more

Respondent Had Rights or Legitimate Interests in Domain Name by Using It to Promote Genuine Business

In the case of Avon Products, Inc. v. Jenika Mukoro, Heirs Holdings, a 3-member WIPO Panel denied the Complainant's efforts to have the domain name avonhealthcare.com transferred because the Complainant failed to sustain its burden of establishing that the Respondent had no rights or legitimate interests in the disputed domain name. The Panel found that the Complainant proved that its trademark AVON (which has been in use since 1929) is well-known in the field of cosmetics... more

Those Who Remember History…

Tom Wheeler, the new Chairman of the Federal Communications Commission, gave a speech today at Ohio State University. It was a good speech on his regulatory philosophy. But that's not so interesting. There's nothing out of the ordinary about a government official giving a speech. The unusual development was that the Chairman also released an ebook, called Net Effects. Even more unusual, it's not a bland ghostwritten policy whitepaper; it's a deeply researched work of history. more

More Cracks Appearing in Mobile Market

When I wrote the BuddeComm analysis on the introduction of Apple's iPhone I commented that the most significant element of this event was that it would begin to create cracks in the flawed business models of the mobile operators, who are desperately hanging on to their closed networks very much like the fixed operators were fighting tooth and nail against opening up their networks. We have seen that the fixed operators have largely lost this battle and we predict that the future of the mobile networks will be no different... more

Fibre Optic Technologies for the Next 50 Years

It might be hard to imagine but we were already talking about fibre to the home networks back in the 1970s and 1980s. This was in the early days of interactive TV and pay TV and fibre optics were already at that time seen as the next level of telecoms infrastructure needed for such services. The first residential fibre pilot networks were built in Berlin and Nagasaki. One of the most ambitious projects was in Columbus Ohio, but in the end they decided to continue with their HFC network. more

FBI vs Apple: A Bit Of Light Reading

Encryption is key to commerce online. Anything that weakens it is a threat to the digital economy, so the FBI vs Apple case is something that a lot of people are watching very closely... The most recent development is that Apple has filed "Motion to Vacate the Order Compelling Apple Inc. to Assist Agents in Search, and Opposition to the Government's Motion to Compel Assistance." Legal filings aren't light bedtime reading, but this one explores the legal issues as well as the privacy and security implications from multiple angles and underlines why this case is so important. more

Broadband Satellite Issues

One of the most interesting aspects of serving broadband from low-orbit satellites is that it brings issues related to space into broadband discussion. Space issues were less important for high earth orbit satellites that sit 20,000 miles above the earth. Other than an occasional impact from sunspots, there wasn't much of note. But there are two recent events that highlight our new focus on low-earth orbit satellites. more

How to Move Telecoms Forward in the USA

In the last few weeks courts in the USA have carried on business as usual. They continue to provide the two major telcos in the USA, Verizon and AT&T, with extraordinary protection -- basically retaining the outdated regulatory system in the USA that identifies the duopoly between the telcos and the cablecos as the best way forward for the development of telecoms competition in this country. This is rather different from the position taken by the new Obama Administration, which has indicated that it will break with past regulations... more

The ITU 2018 Plenipotentiary Conference: An Analyst’s Long-Arc Perspective

Next Monday, 29 October, most of the formal representatives of the world's nations will convene for three weeks to collectively consider the most significant developments in global network communications networks and services, and make multilateral adjustments in a treaty instrument signed by almost every country at the end. They will also elect heads of the various International Telecommunication Union (ITU) secretariats and permanent bodies for the next four years. more
