The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more
Size and cost have always been restraining factors to the utilization of computers. The first computers occupied whole rooms. When personal computers arrived, they were still rather bulky. Today, we have slim ultrabooks and compact small form factor PCs. Computers are not only getting smaller in this age, they're also becoming cheaper. And single-board computers like the Raspberry Pi are taking cost and size down a step further. These units bring compact and affordable processing to the masses. more
Carlos Slim of Telmex tells me the world is about to change. "Two billion more people will connect to the Internet when smartphones cost $50. The phone makers are promising me a $50 phone in 2014." If Spreadtrum and Firefox deliver a $25 smartphone, as promised, that could accelerate takeover. ~310,000,000 Africans will be connected to the Internet in 2017, Arielle Sumits of Cisco predicts... It's inevitable that the U.S. will be dwarfed by the rest of the world. more
We're just back from Mobile World Congress in Barcelona, Spain, where more than 85,000 attendees from over 200 countries gathered to discover what the 1,800 companies present had to showcase. As expected, some of the show's biggest themes focused on the Internet of Things, the mobile cloud, Big Data, 4G LTE and wearable devices... After speaking to a cross-section of service providers, it became clear that many operators are already starting to leverage their investment in existing 4G LTE infrastructure... more
Recently during an afternoon meeting with a friend of mine, Bob Ochieng, who happens to work for ICANN (Internet Corporation for Assigned Names and Numbers) Africa Operations, he lamented that at online Internet Governance discussions fora such as CircleID, and 1net.org, there is no serious frequent engagements from African Voices. This got me thinking and I realized that most African Internet Stakeholders would rather use a "wait and see approach" in matters as critical as Internet Governance. 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
AT&T got critics' keyboards activated by announcing plans for a Sponsored Data service, enabling websites to pay for their end-users data consumption. The service has been characterized as a type of toll-free or "1-800? style service for mobile data. Does this contravene network neutrality principles? AT&T says the traffic from the sponsoring sites will be treated the same as other traffic on the network. A US public interest group, Public Knowledge, claims this is precisely what a net neutrality violation looks like. more
For generations, large pockets of Africa were isolated from things many of us take for granted: access to medical treatment and advances that can make the difference between a healthy, productive life or debilitating illness -- or even an early death. These problems still persist, but over the last two decades technology has helped break through and enable medical professionals to reach the poorest and most remote populations and offer some hope. more
Much of the discussion regarding mobile security revolves around the growing "pandemic" of mobile malware. It's not uncommon to see headlines reporting the discovery of large numbers of new malware samples. However, as Google recently pointed out, with quite a bit of data to support them, there's little discussion of real world impact of these discoveries. This raises a number of relevant questions. Is the average user likely to be infected? Where does this malware come from? These are questions that deserve analysis and thoughtful responses. more
There are often confused reports in the media about mobile and fixed broadband, with arguments that one could replace the other. Yet the reality is that they coexist and complement each other - perhaps even more so since one cannot manage without the other. Increasingly, devices such as smartphones, tablets and smart TVs are at the end of fixed lines, with a wireless (WiFi) connection between the fixed line and the device. more
