March 27, 2012 01:40 PM
Carriers like AT&T and Verizon Wireless are using data caps to manage the explosive growth in 3G/4G data consumption. Hey, kids--the 1990s called and wants its bandwidth management strategy back. As Lee Badman points out in "4G? No, It's More Like 4Gee!" the data rates available to wireless consumers are growing rapidly and our demand is keeping pace. When you have high demand and data caps, the chance of overages is very likely, and the last thing anyone wants is out-of-control telecom costs. Consumers don't have much choice in managing data caps, but enterprises have more options.Nicira's Network Virtualization Platform Release Raises Questions

February 08, 2012 11:00 AM
While the Internet Society (ISOC), a global Internet standards-setting group, has seen a pickup in adoption of IPv6 by some measures, conversion from the IPv4 standard is still relatively slow. The ISOC has scheduled another IPv6 Day for June 6, hoping to build on the momentum for adoption of the new Internet Protocol from IPv6 Day on June 8, 2011. In a three-part series, Network Computing will look at how companies can develop a road map for IPv6 conversion, the technical implications of running IPv6 on an existing IPv4 network, and what compliance and security issues have to be addressed in a transition.Getting To Know 4G
July 21, 2010 10:30 AM
Just like 802.11n was a world-shaker in the WiFi realm, mobile telecommunications networks are beginning to experience a significant leap forward in capability. And just like with the "artistic marketing license" taken by WiFi 11n makers (9 times the old stuff! 6 times bigger this and that!), you have to dig through the PR to figure out what's really coming with the new 4G (4th Generation) mobile networks.Most Mobile Data Consumed By Six Percent Of Users
July 02, 2010 11:25 AM
A significant percentage of U.S. smartphone users aren't using data at all, while the top 6% of users are gobbling up half of all data consumed, according to Nielsen. Released this week, a study of 60,000 mobile phone bills found a huge disparity between heavy data users and the many smartphone owners who use their handsets almost exclusively just for voice calls and texting.Carriers Speak: Inside Tips for IPv6 Services
