If Slate Comes in Standard Sizes, Why Not Broadband?

Last week I was at the National Slate Museum in Wales watching slate being split apart. On the wall were sample pieces of all the standard sizes. These have cute names like "princess". For each size, there were three standard qualities: the thinnest are the highest quality (at 5mm in thickness), and the thickest have the lowest quality (those of 13mm or more). Obviously, a lighter slate costs less to transport and lets you roof a wider span and with less supporting wood, hence is worth more. more

7 Reasons Why R&E Networks and Universities Are Critical to Future of Broadband

There has been considerable discussion about the future of broadband in terms of infrastructure i.e. fiber, wireless, community owned etc. However, there has been little discussion, to borrow a phrase from Internet 2, on Net+ broadband services. It is in the Net+ services where I think R&E networks can play a critical in helping communities and small commercial ISPs deploy advanced services and applications that will provide new business models to underwrite the costs of next generation broadband. more

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

Senate Judiciary Leaders Ask New IP Czar to Facilitate ICANN-Focused Conversations

Daniel Marti was nominated to become the new White House "IP Czar" in August 2014 to replace Victoria Espinel. His predecessor, in yet another illustration of Washington's "revolving door" shuffling key individuals between the government and private sector, departed the post a year earlier to become head of BSA/The Software Alliance, the leading trade group for the software industry. more

Taking Stock of New gTLDs in the Public Markets

A woman on the radio talks about revolution, though it's already passed. The window is now closed. A snapshot can be taken. A baseline can be set. How have the public markets valued the new gTLD program? And more importantly, how will public markets value it going forward? Until a few months ago, the new gTLD program was arcane policy discussion among a very narrow technical population of the Internet community. more

Mobile Broadband Boom: The Killer App for FttH

It still amazes us that respected industry commentators join liberal politicians in questioning the need for FttH in the wake of the enormous success of mobile broadband. They refer to this phenomenon as proof that people are bypassing their fixed broadband and are now using the smartphones and tablets to obtain most of their broadband access. However, after several years of mobile boom the majority of households are still using the fixed-line networks for calls... more

Turn the Table on Content Filtering

Why do we run content filters at the recipient's side? Paul Graham's Plan for Spam introduced them that way. After several years, we can say that plan doesn't work very well. Email has become much less reliable. One way to recover reliability, at least between trusted parties, is to run filters at the sender's side. Let's look at the diagram in more detail... more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 3)

Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more

Article 28 of the NIS2 Directive and the DNS Industry

At a workshop on the implications of Article 28 for the DNS industry organized by eco -- Association of the Internet Industry in October 2023, stakeholders from the DNS industry, the European Commission, national governments, and the ICANN community convened to discuss the challenges facing the DNS industry and to work together on avoiding fragmentation as much as possible. more

Informal Working Group Publish Report On New TLDs

In an interesting move several members of the ICANN community formed an "informal" Working Group to discuss the concept of "expressions of interest" in new Top-Level Domains (TLDs). This all happened very quickly, which is more or less the opposite to how most ICANN related activities progress. ...The report, which runs to about 11 pages, is concise and seems to have covered most of the areas of interest. more

Transition of the Telecoms Industry Is Overdue

It is interesting to observe the changes in the telecommunications environment over the last few decades. Before videotex (the predecessor of the internet) arrived in the late 1970s early 1980s, 90% of telecommunications revolved around telephone calls. And at that time telephony was still a luxury for many, as making calls were expensive. I remember that in 1972 a telephone call between London and Amsterdam cost one pound per minute. Local telephone calls were timed... more

America Planning for the Closure of Its Copper Network

In an interesting move the FCC's Technical Advisory Council has outlined the need for setting a 'sunset' date for the closure of the circuit switched network. This is a first step that eventually could lead to the replacement of the PSTN in the USA, rather than letting the network slowly fade into oblivion the FCC proposes the bring the issue in the open so that it can be properly evaluated and discussed. more

In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more
