I've been prompted to write this brief opinion piece in response to a recent article posted on CircleID by Tony Rutkowski, where he characterises the IETF as a collection of "crypto zealots." He offers the view that the IETF is behaving irresponsibly in attempting to place as much of the Internet's protocols behind session level encryption as it possibly can. ... Has the IETF got it wrong? Is there a core of crypto zealots in the IETF that are pushing an extreme agenda about encryption? more
As we start moving more real-time communications into web browsers with the upcoming WebRTC/RTCWEB offerings, what do we do about congestion control? How do we ensure that all these browser-based communications sessions share the network fairly? With RTC capabilities now already available in builds for browsers such as Google Chrome and Mozilla Firefox, how do we deal with the expected increase in voice, video, chat and data traffic? more
The debate around encryption has become a hot topic in a world where communications are increasingly becoming digital. The modern encryption debate is a complex and nuanced issue, with many players from different backgrounds trying to influence the conversation. The question of balancing the need for national security with the right to privacy has been a matter of public debate for years. Only recently has the issue been framed in terms of encryption, but the discussion is certainly not new. more
This weekend brought the great news that Google's IPv6 statistics have shown that connections over IPv6 to Google's web sites hit the 2% threshold for the first time. (You can see for yourself.) While 2% sounds tiny, as I wrote in a Deploy360 post today, the important fact here is that this represents a doubling of IPv6 traffic to Google over the past year! more
We used to think of computer networks as being constructed using two fundamental common infrastructure components: names and addresses. Every connected device had a stable protocol address to allow all other devices to initiate a communication transaction with this device by addressing a data packet to this protocol address. And every device was also associated with a name, allowing human users and human use applications to use a more convenient alias for these protocol addresses. more
How can the open standards organizations of the IETF and W3C "strengthen the Internet" against large-scale pervasive monitoring? That is the topic up for discussion at the "Strengthening the Internet Against Pervasive Monitoring (STRINT)" workshop planned for February 28 and March 1, 2014, and jointly sponsored by the Internet Architecture Board (IAB) and the W3C. The workshop is by invitation-only and has a deadline of Monday, January 20, 2014 (by 11:59 UTC) for submission of either position papers or Internet drafts. more
In previous posts in this series, I've discussed a number of applications of cryptography to the DNS, many of them related to the Domain Name System Security Extensions (DNSSEC). In this final blog post, I'll turn attention to another application that may appear at first to be the most natural, though as it turns out, may not always be the most necessary: DNS encryption. (I've also written about DNS encryption as well as minimization in a separate post on DNS information protection.) more
I work at APNIC, the Regional Internet Registry that serves the Asia Pacific Region. APNIC provides common infrastructure services for the region that support the unique assignment of IP address blocks to Internet network operators within our region through the operation of an address registry. In short, IP addresses are what we do. So, when there are discussions in technology circles about evolving the Internet's address model in varying ways,... more
On World Telecommunications Day last Saturday, the question of the digital divide?the difference between the so-called "developed" and "less developed" countries in terms of the availability and use of new information and communications technologies, particularly regarding access and use of the Internet?was one of the main topics of debate. However, less is understood about the growing knowledge and participation divide between "developed" and "undeveloped" countries on decisions regarding the global structure of the Internet that is currently under the mandate of the Internet Corporation for the Assigned Names and Numbers (ICANN)... more
In a move to be celebrated by many of us with a VoIP background, the United States Federal Communications Commission (FCC) announced today the appointment of Henning Schulzrinne as Chief Technology Officer (CTO). As the release indicates, Henning's role as CTO will be to: ...guide the FCC's work on technology and engineering issues, together with the FCC's Office of Engineering and Technology. more
A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last. more
"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more
It is an open secret that the current state of IPv4 allocation contains many accidental historical imbalances and in particular developing countries who wish to use IPv4 are disadvantaged by the lack of addresses available through ordinary allocation and are forced into purchasing addresses on the open market. As most of the addresses for sale are held by organisations based in the developed world, this amounts to a transfer of wealth from the developing world to the developed world, on terms set by the developed world. more
As the second Internet Governance Forum approaches, it is an appropriate moment to take stock of how the Internet Governance dialogue has evolved since the conclusion of the WSIS Summit in 2005. One year after the first IGF in Athens, it is clear that government, industry and civil society stakeholders are still grappling over the direction and focus of the IGF... There is little doubt that some governments will choose to borrow concepts from the IGF when developing law and policy and will ultimately apply them to the Internet within their respective jurisdictions. Given the global nature of the Internet, this should be a fundamental concern. While this important dialogue about the Internet continues at the IGF in Brazil next month, another no less important debate is emerging with regard to RFID technology and the so-called "Internet of Things." The Internet of Things is a term coined to describe a future ubiquitous sensor network that collects commercial and personal data in public and private settings created, in part, through the rollout of RFID technology... more
I'm sure we've all heard about "the Open Internet." The expression builds upon a rich pedigree of term "open" in various contexts. For example, "open government" is the governing doctrine which holds that citizens have the right to access the documents and proceedings of the government to allow for effective public oversight, a concept that appears to be able to trace its antecedents back to the age of enlightenment in 17th century Europe. more
