The EC recently approved technical rules on how the 900MHz and 1800MHz frequency bands should be utilised for 4G services, including LTE and WiMAX. National governments have until the end of 2011 to implement the decision into national legislation. Restrictions were initially imposed by the 1987 GSM Directive which limited these bands for 2G. more
Google yesterday dove deep into its Chrome notebook project at its annual Google I/O conference. The company has had the notebook operating system in beta for almost two years now. Google announced the first market-ready Chromebooks from partners Samsung and Acer. The Chrome OS is dependent on the cloud for storage and various web-based applications. The result is a machine that boots in a matter of seconds and carries very little in the line of native hardware. more
A year ago, the RIPE NCC introduced IPv6 RIPEness -- a system that rates IPv6 deployment of Local Internet Registries (LIRs)... Now, one year later, the numbers have gone up... In absolute numbers: more than 3,000 LIRs have IPv6 address space. This means that the RIPE NCC has made more than 1,100 IPv6 allocations within 12 months. more
In the fourth quarter of 2010, a mobile provider in Greece (GR-1) had the highest average connection speed, at just over 4.5 Mbps, according to Akamai's latest State of the Internet Report. "The mobile providers in Slovakia and Russia that had previously been reported as having the highest average connection speeds were removed from consideration in the fourth quarter, as further research determined that their autonomous systems carried a mix of traffic from fixed and mobile connections." more
A new research on native IPv6 traffic across six large providers in North America and Europe suggest that despite fifteen years of IPv6 standards development, vendor releases and advocacy, only a small fraction of the Internet has adopted IPv6. "The slow rate of IPv6 adoption stems from equal parts of technical/design hurdles, lack of economic incentives and general dearth of IPv6 content." more
On Monday, 11 April 2011, Level 3 announced they had entered a definitive agreement to acquire Global Crossing. According to the Renesys Market Intelligence rankings, this merger would bring together the world's #1 and #2 global providers, with over half the Internet market on earth dependent on the combined entity. If the deal gained regulatory approval in the US and elsewhere today, how would the Internet provider landscape change? We'll answer that question in this blog, giving the proposed union a fictional name of Level Crossing for the purposes of our discussion. more
The U.S. Sate Department annual human rights report released on Friday has expressed concerns over the increasing trend among governments spending more time, money and attention in efforts to control their citizens access to the Internet and other communication means. To aid people seeking to speak out, the U.S. government is helping to finance circumvention technologies to avoid firewalls, reports the Associated Press. "To deal with governments hacking computers or intimidating dissenters, the U.S. government has trained 5,000 people from around the world on how to leave less of a trace on the Internet." more
The broadband sector, like the wireless sector, is one of the strongest growth areas of telecommunications. Unlike most OECD countries, where DSL tends to dominate, the majority of subscribers in the US fixed broadband market are cable subscribers. During 2010 the gap continued to widen as the cable companies accounted for 70% of new broadband subscribers compared to the telcos' 30%. Although new broadband networks such as FttH and WiMAX are being widely deployed, broadband competition in each region is still generally limited to one DSL and one cable operator. more
During the recent political unrest in the Middle East, researchers have observed significant changes in Internet traffic and connectivity. Typically people look at routing data, latencies when connecting to sites and search and query statistics. Here we show results from a previously unused source of data: unsolicited Internet traffic arriving from Libya. The traffic data we captured shows distinct changes in unsolicited traffic patterns since 17 February 2011. more
Images of clouds have been used when discussing networks for quite some time. When traditional telecoms companies were selling point-to-point circuits a drawing of a cloud was sometimes used. The cloud symbol helped indicate the provider?s domain of responsibility, effectively hid the internal complexity of the network and focused on the end user. This was all fine when the product offered was an end-to-end circuit. more
The 8.9-magnitude earthquake in Japan rocked the northeastern portion of the coast. The quake was the strongest to hit Japan in at least a century, sending a tsunami that flooded northern towns and also reached portions of the United States, including Hawaii. The quake was followed by a 7.1-magnitude aftershock. Impact on Internet connectivity... Japan’s Internet performance seemed to have emerged largely unscathed, but concerns continue for the telecommunications infrastructure as the country struggles to meet power demands in a state-of-emergency. more
James Cowie from Renesys reports: "8.9 magnitude earthquake in Japan has had surprisingly limited impacts on the structure and routing dynamics of the regional Internet. Of roughly 6,000 Japanese network prefixes in the global routing table, only about 100 were temporarily withdrawn from service -- and that number has actually decreased in the hours since the event. Other carriers around the region have reported congestion and drops in traffic due to follow-on effects of the quake, but most websites are up and operational, and the Internet is available to support critical communications." more
Canadian Industry Minister Tony Clement has announced that the Harper government will overturn the CRTC's decision that effectively ends "unlimited use" Internet plans if the regulator doesn't rescind the decision itself. more
In a Renesys blog post, James Cowie writes: "Why did Libya put its Internet in 'warm standby mode' instead of just taking it down, as Egypt did? Perhaps because they're learning from Mubarak's experience. Cutting off the Internet at the routing level (powering down the Internet exchange point, going after the remaining providers with secret police to enact a low-level shutdown) was a technically unsophisticated desperation move on Egypt's part." more
Pretty much as long as there've been computers, one of the biggest challenges has been user education. How do you create software smart enough to inform a user when they're about to do something potentially disastrous - or, worse, when something disastrous has been done to them? As one of the world's largest access providers, Comcast has put a ton of thought into developing a notification system for their users. The solution Comcast developed involves, in effect, hijacking HTTP requests... more
