Why Understanding Bandwidth is Essential for Improving Subscriber QoE

Measuring and managing subscriber bandwidth can be an easy and cost-efficient way to improve subscriber quality of experience (QoE). In a HFC cable network, bandwidth is shared among users in the same fiber-node. Even though improvements in DOCSIS technology has allowed a substantial increase of bandwidth availability per fiber-node, a few heavy users - as well as new 4K video content - can quickly kill recently-made network investments and leave subscribers with an impression that they are not receiving the quality they deserve. more

Spam Continues to Drop

The chart in this post shows the amount of inbound mail that we see, both spam and non-spam, over the past three and a half years. You can see in the above that the amount of good mail that we see has continued to increase over time. This is because of an increased customer base, not because the total amount of good mail worldwide has gone up... However, the amount of spam has plummeted from 23,000 in mid 2010 to 5000 now, a drop of over 75%. The contrast couldn't be starker -- spammers are not spamming as much anymore. It almost looks like the battle against spam is almost over. What's still left to do? more

What’s the Right Definition of Upload Speed?

I read a blog on the WISPA website written by Mark Radabaugh that suggests that the best policy for broadband speeds would be met by asymmetrical architecture (meaning that upload speeds don't need to be as fast as download speeds). I can buy that argument to some extent because there is no doubt that most homes download far more data than we upload. But then the blog loses me when Mr. Radabaugh suggests that an adequate definition of speed might be 50/5 Mbps or 100/10 Mbps. more

The Name Collision Conference

Earlier this week Verisign sponsored a two day conference on name collisions in the DNS. Despite the very short time frame in which it was organized, only a month from announcement to meeting, there were some very good presentations. I'll just hit some highlights here; all of the papers and slides are on their web site at namecollisions.net. Sunday morning started with a keynote by Bruce Schneier, who is not a DNS expert (and doesn't claim to be) but had some interesting observations on names in general. more

Officially Compromised Privacy

The essence of information privacy is control over disclosure. Whoever is responsible for the information is supposed to be able to decide who sees it. If a society values privacy, it needs to ensure that there are reasonable protections possible against disclosure to those not authorized by the information's owner. In the online world, an essential technical component for this assurance is encryption. If the encryption that is deployed permits disclosure to those who were not authorized by the information's owner, there should be serious concern about the degree of privacy that is meaningfully possible. more

Is the Web a “Communications Medium”?

I've been having a short Twitter exchange with Paul Downey (@psd), someone who I hold in high intellectual and personal regard. I've made an assertion that has Paul snorting his coffee back up through his nose and into his keyboard: that the Web is not a communications medium. Justifying this claim can't be done in 140 characters. Now, there is a sleight of hand I'm pulling off here. You can build communications media on the Web, but my claim is that the Web itself is not one, and that has subtle but significant consequences. more

Dot UK, A No-Brainer!

British registry Nominet has launched a consultation on whether .UK should be opened up at the top level under a scheme called direct.uk. Currently, registrations are only allowed at the second level, .CO.UK being Britain's main Internet suffix. The question really isn't should this be done. The question is: why has it taken so long to get here? more

The Test of Time at Internet Scale: Verisign’s Danny McPherson Recognized with ACM SIGCOMM Award

The global internet, from the perspective of its billions of users, has often been envisioned as a cloud -- a shapeless structure that connects users to applications and to one another, with the internal details left up to the infrastructure operators inside. From the perspective of the infrastructure operators, however, the global internet is a network of networks. It's a complex set of connections among network operators, application platforms, content providers and other parties. more

ICANN’s Tokyo Meeting Provides a Little More Clarity on the New gTLD Program

New gTLDs continue to be a major topic of discussion within ICANN circles, and the regional meeting currently underway in Tokyo has revealed some interesting updates for potential applicants. ICANN's Chief gTLD Registry Liaison, Craig Schwartz, delivered a great presentation on the progress being made behind closed doors at ICANN and provided the attendees with an insight into a couple of key changes that are likely to be seen in the Final Applicant Guidebook. more

AI in Academia: Tool or Trap? Balancing Innovation and Intellectual Honesty in the Digital Age

AI has revolutionized how we process information, optimize tasks, and conduct research. However, its integration into academia sparks ethical and practical debates. Should we limit its use? How can we assess a student's true knowledge if they employ these tools? This text explores these questions from the perspective of a technology expert who argues that banning AI is as absurd as rejecting calculators or spreadsheets in the past. more

How to Protect Your Brand in Web3

In 2014, computer scientist Gavin Wood coined the term "Web 3.0." The phrase, which has now been shortened to "Web3", refers to the third generation of the internet that's designed to be truly decentralised and free from a central authority. Web3 has the potential to add real-world value for businesses by creating additional avenues to reach consumers. However, owing to its less regulated nature, brands also have the potential to be taken advantage of both by users and by the providers in the space. more

Mobilizing Russian Population Attacking Georgia: Similar to the Estonian Incident?

It seems like the online Russian population is getting mobilized. Like a meme spreading on the blogosphere, the mob is forming and starting to "riot", attacking Georgia. This seems very similar to the Estonian incident, only my current guess is natural evolution rather than grass-roots implanted -- but I am getting more and more convinced of the similarities as more information becomes available. Determining exactly when the use of scripts by regular users started, is key to this determination. more

The Mobile Messaging Wars - and Why Facebook Is Forcing Users to Use Its Messenger App

In the ongoing war for mobile messaging dominance and "what will replace SMS", Facebook has decided to annoy a serious part of their user base and force all mobile users to move to Facebook's separate Messenger app. In a short period of time, you will be forced to install the Messenger app if you want to send messages to Facebook friends while using your iOS or Android mobile phone. more

IPv6 Day a Couple of Days After

June 8th IPv6 World day came and went without any major glitches, let alone disruption of the internet, and witnessed varying traffic fluctuations depending where on the net observations were made. From a Tata Communications AS6453 perspective, a global tier 1 IP wholesale network, data gathered by a number of probes gave an interesting pulse on what happened in some major international arteries of the internet. more
