Earlier this week, I came across a working paper from Professor Peter Swire - a highly respected attorney, professor, and policy expert. Swire's paper, entitled "Online Privacy and ISPs", argues that ISPs have limited capability to monitor users' online activity. The paper argues that ISPs have limited visibility into users' online activity for three reasons: (1) users are increasingly using many devices and connections, so any single ISP is the conduit of only a fraction of a typical user's activity; (2) end-to-end encryption is becoming more pervasive, which limits ISPs' ability to glean information about user activity; and (3) users are increasingly shifting to VPNs to send traffic. more
I often think there are only two types of stories about the Internet. One is a continuing story of prodigious technology that continues to shrink in physical size and at the same time continue to dazzle and amaze us... The other is a darker evolving story of the associated vulnerabilities of this technology where we've seen "hacking" turn into organised crime and from there into a scale of sophistication that is sometimes termed "cyber warfare". And in this same darker theme one could add the current set of stories about various forms of state sponsored surveillance and espionage on the net. more
The law set by U.S. Government for all agencies to fully remove the controversial Russian based Kaspersky Lab security software by October is proving a lot harder than anticipated. more
NORDUnet, the R&E network connecting the Nordic countries has recently undertaken a brilliant Internet peering strategy that will have global significant ramifications for supporting research and education around the world. NORDUnet is now emerging as one of the world's first "GREN"s -- Global Research and Education Network. NORDUnet is extending their network infrastructure to multiple points of presence throughout the USA and Europe to interconnect to major Internet Exchange Points (IXPs). more
In my previous post, I talked about the significance of DNS in connection with the Software Defined Data Center (SDDC) and Software Defined Networking. Although the second generation DNS provisioning model I outlined should have seemed straight-forward enough, in real life it is anything but. In my view, the real-world complications of a seemingly trivial issue are largely related to how the network industry approaches IP addressing. more
Mobile Network Operators (MNOs) serve the largest constituent of connected devices. There are over 4.6B GSM (and its derivatives) subscriptions today. When you add the CDMA family along with technologies with smaller footprints such as WiMax, IDEN to this list, that number tops 5B mark. On the other hand there are only (yes only!) 800M Internet hosts per ISC. Considering such a small percentage of those 5B or so devices are capable of being an Internet host and out of that percentage even a much smaller percentage is connected at a given time, one can understand the sheer potential of explosion in the number of Internet hosts as mobile devices in the next 3-5 years. more
With 2019 coming to a close, we're not just saying goodbye to the past 365 days, we're also saying goodbye to an entire decade. As we bid farewell to the 2010s, we're taking this opportunity to look back and reflect on the digital decade as well as consider what the future might have in store for us all. The past ten years were a whirlwind of change, with new advances in technology exploding onto the market at a faster pace than ever before. more
When Columbus Networks and Cable & Wireless Communications announced the formation of their new joint venture entity at International Telecoms Week 2013, it signaled an important milestone for the telecommunications sector in Latin American and the Caribbean. The development comes at a time when the region's appetite for bandwidth is rapidly rising. The market for wholesale broadband capacity is experiencing solid growth and shows no sign of slowing anytime soon. more
In January 1995, the RFC Editor published RFC 1752: "The Recommendation for the IP Next Generation Protocol"... The Internet is a security officer's nightmare -- so much openness, so easy to capture packet traffic (and/or spoof it!) and send all manner of unwanted traffic. It was built as a research network, hosted by institutes that were 1/ professionally responsible and 2/ interested in working together collegially. So, in the 19 years since the publication of that statement, have we really failed to address the stated goal? more
As most CAUCE supporters already know, forging 'From:' or other commonly seen email headers is trivially easy. It's one of the most frustrating oversights in the creation of Internet email technology -- though of course that's only obvious in hindsight; it was just fine for the pre-Internet networks of the late 1970s and early-mid 1980s. Since then, things have changed -- and the most interesting recent technological advancements in email have been in the realm of sender authentication, which encompasses ways to verify that the apparent sender of a message actually is the entity which sent it. more
Last Sunday I attended the 10th meeting of the UN Broadband Commission for Digital Development in New York, where we launched this new report -- State of Broadband Report 2014. Here are some of the highlights of the report. Over 50% of the global population will have Internet access within three years' time, with mobile broadband over smartphones and tablets now the fastest growing technology in human history, according to the 2014 edition of the State of Broadband report. more
An unprecedented disinformation campaign purposefully distorts what consumers and governments understand about the upcoming fifth generation of wireless broadband technology. A variety of company executives and their sponsored advocates want us to believe that the United States already has lost the race to 5G global market supremacy and that it can regain it only with the assistance of a compliant government and a gullible public. more
The Internet has managed to collect its fair share of mythology, and one of the more persistent myths is that from its genesis in a cold war US think tank in the 1960's the Internet was designed with remarkable ability to "route around damage." Whether the story of this cold war think tank is true or not, the adoption of a stateless forwarding architecture, coupled with a dynamic routing system, does allow the network to "self-heal" under certain circumstances. Can we see this self-healing in today's network? more
The industry would like to project 5G as a divergence from previous mobile technology evolution lines (1G-2G-3G-4G). They claim that this is a whole new ballgame, with completely new opportunities. But the big question will be whether this time round the telcos will be able to harness this new technology to create new business opportunities for themselves. 5G is only one element of a larger ecosystem that includes broadband access, IoT, M2M, cloud computing, data centres and data analytics... more
By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills - and the quality assurance budgets - that something the size of the Internet deserves. more
