Internet2 Sets New Land Speed Record -- 9 Gbps

An international team led by the University of Tokyo has set two consecutive new Internet2 Land Speed Records (I2-LSR) in the
IPv6 single and multi-stream categories. The team, which also included WIDE Project, NTT Communications, JGN2, SURFnet, CANARIE, Pacific Northwest Gigapop and other institutions, used a network path that spanned 30,000 km across 6 international networks. They trasmitted transferred data in the single and multi-stream categories at a rate of 7.67 Gbps, which is equal to 230,100 terabit-meters per second (Tb-m/s). This record setting attempt leveraged standard TCP to achieve the new mark.



In a follow-up test, the team used a modified version of TCP to achieve an even greater record. Using the same 30,000 km path, the network was able to achieve a throughput of 9.08 Gbps which is equal to 272,400 Tb-m/s for both the IPv6 multi and single stream categories.

Reinventing
the IAD



The
boundary between service provider network and residential subscriber is
rapidly blurring. At the heart of this evolution is the vision of the
"digital home", which offers service providers an opportunity to
generate additional revenue through bundled services and associated
service level agreements.


Tellabs Posts Q1 Revenue of $452 Million, Down 12%

Tellabs reported Q1 revenue of $452 million, down 12% from $515 million in the first quarter of 2006. Tellabs earned $25 million or 6 cents per share in the first quarter of 2007 on a GAAP basis, down 51% from $52 million or 11 cents per share in the first quarter of 2006.

  • Broadband - First-quarter revenue from the broadband segment totaled $219 million, down 16% from $260 million in the first quarter of 2006.

TI Licenses Super Wideband Codec from Fraunhofer for HD Voice

Texas Instruments is licensing the Low Delay AAC super wideband codec from the Fraunhofer Institute for Integrated Circuits IIS to enable high-definition (HD) VoIP.



Powered by TI's high-performance digital signal processors (DSPs), the MPEG-4 AAC-LD super-wideband codec offers substantial benefits compared to earlier wideband audio technology, and has the performance capabilities to make ubiquitous HD voice a reality in global IP networks.



The super-wideband codec technology is able to transmit voice at a sample rate of up to 48 KHz, providing near-CD quality audio at data-rates of 48 - 64 kbps for better clarity with applications like IP-based voice and video, as well as transmission of music over the telephone.



TI predicts that just as HD television is revolutionizing the way we watch TV and HD radio enhances the daily commutes for millions of people each day, HD voice will deliver a uniquely crisp and clear communications experience. It will also be a critical enabling technology for a host of exciting applications in the future, such as improved speech recognition, real-time language translation, and appliance voice control.



With this new super-wideband technology, TI's VoIP solutions can deliver CD-quality sound on both ends of a VoIP-enabled phone call, while supporting a full range of voice and music capabilities, including fidelity comparable to MP3 audio. http://www.ti.com/visionforvoice









HD
Voice: Can VoIP Do Better Than "Carrier Grade"?
Constrained
by the limitations of analog transducers and network bandwidth in its
early days, the public switched telephone network (PSTN) transports only a
small slice of what people can hear. Even though the range of the ear
extends from 20 Hz to 20 KHz, a typical analog phone call only transmits
sound in the 200 Hz to 3.3 KHz range. As IP phones become more and more
prevalent in homes, SMBs and global enterprises, wideband HD voice
communication will become more common. A digital channel from end-to-end
is needed for a wideband call, but this does not preclude a
wired-to-wireless HD call.

Alcatel-Lucent's Preliminary Results Indicate Soft Q1

Alcatel-Lucent issued preliminary results for Q1 2007, saying revenues for the quarter are estimated to be approximately EUR 3.9 billion, a year over year decline of around (8)% at a constant Euro/USD exchange rate or (12)% at current rate. Compared to a strong first quarter 2006, the lower volume is primarily attributable to wireless radio and core networks impacting the Wireless and Convergence businesses globally. The wireless decline is largely driven by lower volumes especially in 2G in some emerging markets.

Patricia Russo, CEO of Alcatel-Lucent said: "It has been four months since we completed the merger, and we are making good progress in terms of our integration. The technology choices have been finalized and the combined company's portfolio communicated to our customers. Concerning our cost saving plans, the net headcount reductions, before recently announced managed services contract wins, are approximately 1,900 during the quarter, 15% of the 3-year target of 12,500. Associated cost savings will be incorporated in our operating results going forward.



As previously stated, we anticipated that some of the factors which affected our business in the fourth quarter 2006 would continue in the early months of the year leading to some revenue decline. In particular, while parts of our businesses performed well, our first quarter results were impacted by lower volumes in traditional wireless and core networks at a time when considerable investments were made in the next generation of these technologies.



We continued to gain sales momentum during the quarter and increasingly recognized the benefits of our integration. At the end of the quarter, our book to bill stands at 1.3x, which leads us to remain confident in our ability to resume growth as the year progresses."http://www.alcatel-lucent.com

CastTV Targets Better Video Search

CastTV, a start-up based in San Francisco, secured $3.1 million in Series A financing for its work developing video search technology.



The company said its video search technology has been developed over the last few years to address the challenges particular to online video search, which are twofold:

  • Online videos are increasingly hidden in the "media Web" -- behind Flash, JavaScript and media player plug-ins -- and therefore hidden from traditional search engines. CastTV has built unmatched proprietary technology that crawls, indexes and extracts metadata from these videos.


  • Metadata associated with videos is often short, incomplete and disorganized. CastTV has developed novel search algorithms that overcome these limitations by incorporating behavioral and extended data.


CastTV also revealed today that it has signed a two-year deal with a major media corporation to provide online video crawling and indexing technology for the company's online video search offering. The funding and customer agreement validate CastTV's technology solution and will accelerate the company's growth and product development.



The funding was led by Draper Fisher Jurvetson. CastTV has named Warren Packard, managing director of Draper Fisher Jurvetson, to its Board of Directors. Packard joins Internet pioneer Marc Andreessen, legendary angel investor Ron Conway and Stanford professor of computer science and director of graduate studies Rajeev Motwani, as Silicon Valley veterans behind CastTV. Andreessen was the co-founder of Netscape and co-author of Mosaic, the first widely-used web browser. Both Conway and Motwani played important roles in the development of Web search -- Conway as an early investor in Google and Motwani as Google's strategic advisor.

Vonage Wins Permanent Stay in Verizon Patent Litigation

The U.S. Court of Appeals for the Federal Circuit in Washington D.C. issued a permanent stay of a previous court's injunction that would have barred Vonage from signing up new customers. Vonage sought the stay following an April 6th decision by the U.S. District Court in Alexandria, Va. enjoining the company from using certain VoIP technology to add new customers.



Vonage said it will continue to serve existing customers by paying into escrow a quarterly royalty of 5.5 percent throughout the appeals process and by posting a $66 million bond as required by the court. The company said it remains confident in the strength of its appeal.

AT&T Adds 691,000 DSL Subscribers in Q1

AT&T reported Q1 net income was $2.8 billion, up from $1.4 billion in the first quarter of 2006, and reported earnings per diluted share were $0.45, versus $0.37 in the year-earlier quarter. Q1 consolidated revenues totaled $29.0 billion, versus a reported $15.8 billion in the year-earlier first quarter.



It was the first full quarter of operations following AT&T's acquisition of BellSouth, with 100% ownership and consolidation of Cingular.



Selected highlights:

  • Broadband: In broadband, there were 691,000 net DSL adds, 90% of them consumer, giving AT&T an installed based of 12.9 million in service.


  • 42% of DSL customers receive speeds of 3 Mbps or more.


  • 33.7% of AT&T's consumer primary lines also have broadband service, compared to 26% a year ago. In California and Nevada, broadband penetration of primary consumer lines is now 42%.


  • Primary consumer lines declined by 285,000 in the quarter, compared to 331,000 in the preceding quarter and 251,000 in the year-ago quarter.


  • Added 187,000 video subscribers in Q1, giving a total of 1.7 million video subs for satellite TV and U-verse.


  • U-Verse: At the end of the first quarter, AT&T had 13,000 U-verse video subscribers. The current number has grown to 20,000 up from 3,000 at the beginning of the year. U-verse installs per week ramped quickly in the first quarter, increasing from about 400 in January to about 2,000 currently. AT&T expects We expect that to ramp throughout the year, reaching 10,000 installs per week by the end of the year. Best of all, more than 80% of our U-verse subscribers are taking higher-end video packages and 65% are taking our highest-speed broadband service, both of which will drive revenues per customer.


  • Wireless: AT&T's total wireless revenues grew 11.2 percent in the first quarter to $10.0 billion. Service revenues, which exclude revenues from sales of handsets and accessories, grew to $9.1 billion, up 13.5 percent versus the year-earlier quarter, reflecting solid subscriber gains and robust growth in data revenues.


  • AT&T's wireless subscribers increased by 1.2 million in the first quarter to reach 62.2 million, up 6.4 million, or 11.5 percent, over the past year. More than 70 percent of first-quarter net adds were retail, and more than 80 percent of those were postpaid. AT&T's gross wireless subscriber additions totaled 4.3 million in the first quarter versus 4.7 million in the year-earlier period.


  • Enterprise: Total revenues from enterprise customers declined 4.4 percent versus the year-earlier first quarter. Excluding CPE revenues and results from acquired and divested assets, recurring service enterprise revenues declined 3.4 percent in the first quarter, compared with declines of 3.6 percent in the fourth quarter of 2006 and 5.0 percent in the first quarter of 2006.
