First Test Labs for Next-Generation Internet Protocol (IPv6) Are Accredited
March 6th, 2010The first two laboratories have recently completed accreditation to provide testing services for the USGv6 Program. The USGv6 Program, developed at the National Institute of Standards and Technology (NIST), provides the basis for expressing U.S. government requirements for Internet Protocol version 6 (IPv6) technologies and for testing that commercial products meet those requirements. The availability of commercial testing services is an important step towards the U.S. government’s use of USGv6 acquisition tools, beginning in July 2010.
The current Internet Protocol (IPv4) provides the basic communication service that inter-connects the global set of networks that comprise the Internet. Designed in the early 1970s, IPv4 is rapidly running out of unassigned, globally unique network addresses. IPv6 was designed by the Internet Engineering Task Force (IETF) as a next-generation replacement for IPv4. With a vastly larger address space, IPv6 will enable the Internet to grow unbounded for the foreseeable future.
The USGv6 Program is intended to assist federal government IT users and acqusition authorities by providing a framework to express and test IPv6 requirements for U.S. government procurements.
ICSA Labs of Mechanicsburg, Pa., and the University of New Hampshire Interoperability Laboratory in Durham, N.H., were accredited by private accreditation bodies operating under the International Laboratory Accreditation Cooperation (ILAC). To become accredited under the USGv6 program, a test laboratory must demonstrate the quality control processes that insure the accuracy, transparency and reproducibility of their testing results and must demonstrate their use of USGv6-approved test methods and test suites. The end goal is to assure vendors and USGv6 users that the conformance, interoperability and capability tests performed at one commercial lab are equivalent to those of any other accredited lab.
“The accreditation of two open test laboratories is a significant achievement for the USGv6 effort,” noted NIST’s Stephen Nightingale, who leads the testing program. “The existence of two accredited labs demonstrates that our test methods and means of inter-laboratory comparisons and quality control are viable; and in fact, we expect that additional commercial labs will come on-line in the future.”

Cisco Quits WiMax Radio Business
March 6th, 2010Cisco Systems will stop developing and making WiMax base stations to concentrate on the IP (Internet Protocol) networks that sit behind them. Cisco acquired Navini Networks, which made WiMax RAN (radio access network) equipment, in 2007. The dominant IP networking company said at the time that it saw a powerful opportunity to bring broadband Internet access to developing countries through WiMax.
However, despite hitting the market first, WiMax has taken a back seat to LTE (Long-Term Evolution) as a 4G (fourth-generation) mobile technology. LTE is backed by the industry body behind GSM (Global System for Mobile Communications) and is on the road maps of most major carriers that have chosen a 4G system. In the U.S., Verizon Wireless plans to launch LTE commercially this year and AT&T will follow next year.
Cisco can serve both markets with products it acquired through its purchase last year of Starent Networks, which made gateways between radio networks and a carrier’s core IP infrastructure. Both WiMax and LTE are based on IP packet networks. In order to concentrate on this business, the company will get out of making the actual radios that deliver WiMax signals to subscribers’ devices.
“Cisco’s mobile strategy has always been to provide a radio-agnostic approach that focuses on the packet core and IP network, where the company can add differentiated value. After a recent review of our WiMax business, we announced a decision to discontinue designing and building new WiMax base stations and modems, and we also announced a support plan for transitioning existing customers,” Cisco spokesman Jim Brady said Friday.
The Navini products haven’t played a big role in high-profile WiMax networks. Cisco is a supplier to the world’s largest WiMax network project, Clearwire’s national U.S. buildout, but only with IP equipment, not radios.
Analysts called the Starent acquisition a move away from WiMax toward the larger LTE market. Unlike WiMax, which had its roots in the wireless LAN world, with strong backing by Intel, LTE is dominated by the giants of cellular equipment, such as Ericsson and Alcatel-Lucent. Cisco has said it does not intend to compete with those types of vendors.
Analysts were not surprised by Cisco’s announcement.
“Cisco pulling out at this moment looks like good business,” said analyst Laurence Swasey of Visant Strategies. He believes LTE will dominate the 4G world and may even be adopted by current WiMax carriers eventually.
Cisco did the WiMax industry a big favor by buying Navini, Swasey said. “It was a stamp of approval at a time when the market was very fragmented as to what 3.5G and 4G would be to the masses,” he said. Today, several major vendors, including Huawei, Samsung and Motorola, are supplying RAN equipment for commercial networks. Cisco’s decision to get out of the business will have far less impact than its choosing to get in, Swasey said.

Touching the Wi-Fi Network
March 6th, 2010First confirm that your network router is working properly for all your other computers and that your iPod Touch is actually connected to it — and not the neighbor’s Wi-Fi network. To see the name of the network, tap the Settings icon on the Home screen and see what is listed next to Wi-Fi. (This advice also applies to the iPhone.)
If you find you are accidentally picking up someone else’s network, tap the name of the network listed to go to the next screen. You should see a list of nearby networks on the next screen. If you are connected to the wrong one, tap the name of your own network in the list and type in any required password; then see if you can get to the Internet on the Touch.
If the Touch shows that you are connected to your own network on the Wi-Fi Networks screen, tap the blue arrow next to the network name. The next screen should show the Wi-Fi network information for the iPod Touch. Unless you have a specially configured network, you probably want to have the option for D.H.C.P. (Dynamic Host Configuration Protocol) selected and the screen should display a series of numbers like the I.P. address. (Every device connecting to the Internet needs one of these Internet Protocol addresses to work.)
If all the numbers are filled in but you still can’t get on the Internet, tap the Renew Lease button, which should give you an updated I.P. address number. Try to connect to the Internet and see if it works.
If it doesn’t, you can reset the information the Touch keeps on hand for this network by tapping the Forget This Network button on the network settings screen. Once you forget the network, return to the screen with the list of Wi-Fi networks, choose your network again and carefully retype the setup and password information.
You can also reset all the network settings on the Touch by tapping the settings icon on the Home screen, tapping General and then Reset and then on Reset All Network Settings. If you still can’t get it to work properly, Apple has other suggestions at support.apple.com/kb/TS1398.
