ECI Telecom Announces "1Net" Converged Framework

ECI Telecom announced "1Net", its framework for helping service providers transition to next-generation networks. ECI 1Net encompasses the company's newly announced Carrier Ethernet 9000 Family and its existing packet-optical and access product lines. The company is also offering a suite of planning, integration and management services to support carriers' business and operational challenges.

ECI Telecom Unveils Carrier Ethernet 9000 Product Line

ECI Telecom unveiled its new Carrier Ethernet 9000 Family, encompassing Carrier Ethernet switch routers, aggregation switches and demarcation units for the metro core, metro access and customer premises. The platforms are designed to deliver high-densities of MEF-certified Ethernet & IP services, including E-Line, E-LAN, E-Tree, IP Multicast for IPTV delivery and IP VPNs.

For the metro core, a new SR9700 model will leverage the company's modular IP/MPLS "ShadeTree" software (originally developed by Laurel Networks) and feature an industry leading density of 1,200 Gigabit Ethernet ports (full-speed) per rack. ECI is powering the SR9700 with a custom-developed programmable ASIC capable of delivering fine-grained QoS, comprehensive OAM and wire-speed performance. The platform scales to 100 Gbps per slot. In addition to a mix of 10/100/GE/10GE interfaces, the platform supports TDM/CES using MPLS. It also offers direct interfaces to the optical transport layer via WDM pluggable optics and built-in OTN (G.709) tunable laser. Two models are initially being introduced. The SR9710 is a 10-slot, 400 Gbps system, and the SR9705 is a 5-slot 200 Gbps system with full interchangeability of line cards between platforms.

For metro aggregation applications, the new product line includes 9200 series for demarc and access deployments. These products feature small form factors, integrated CES capabilities, fast ring-protection and a mix of 10/100 and T1/E1 interfaces.

The 9000 Family is highly integrated with ECI's WDM/ROADM and Multi-Service Provisioning Platforms (MSPP) based on the XDM and BroadGate metro networking platforms. ECI said this integration of the optical layer with the IP/Ethernet layer uniquely positions it to deliver the most complete view of potential network services via one converged network. The 9200 Series includes the AS9205 compact carrier grade FE aggregation switch, the AS9220 carrier grade multi-service aggregation switch, the DM9234 high performance Ethernet demarcation unit and the DM9225 compact demarcation unit.

The new Carrier Ethernet will use ECI's LightSoft unified management application, which now spans all network layers (Optical, Ethernet, IP). Carrier trials are underway.

IBM Develops Nanophotonic Switch for Multi-Core Chips

Researchers at IBM have developed a nanophotonic switch for routing optical data between cores in future computer chips. Like a long-haul fiber-optic network, such an extremely miniature on-chip network will transmit, receive, and route messages between individual cores that are encoded as a pulses of light. IBM estimates that by using light instead of wires, as much as 100 times more information can be sent between cores, while using 10 times less power and consequently generating less heat.

The report on this work, entitled "High-throughput silicon nanophotonic wavelength-insensitive switch for on-chip optical networks" by Yurii Vlasov, William M. J. Green, and Fengnian Xia of IBM's T.J.WatsonResearchCenter in Yorktown Heights, N.Y. is published in the April 2008 issue of the journal Nature Photonics. This work was partially supported by the Defense Advanced Research Projects Agency (DARPA) through the Defense Sciences Office program "Slowing, Storing and Processing Light".

IBM said its researchers have demonstrated several critical characteristics for the nanophotonic switch. First, the switch is extremely compact -- as many as 2000 would fit side-by-side in an area of one square millimeter. Second, the device is able to route many wavelengths simultaneously. With each wavelength carrying data at up to 40 Gbps, it is possible to switch an aggregate bandwidth exceeding 1 Tbps.

Verizon and Pando Discuss P2P Traffic Experiment

Verizon will begin using a peer-to-peer (P2P) file transfer system from Pando Networks to aid with the distribution of large media files to its broadband users. When deployed, the new system will move material authorized by the content owners -- such as movies, TV programs, software or large data bases -- faster for consumers and more efficiently for network operators, including Verizon.

Verizon said it no longer regarded P2P as a "dark-alley distribution system for unauthorized file sharing.

The new system and tests were described in a presentation Friday (March 14) in New York by Douglas Pasko, Verizon senior technologist and co-chair of the P4P Working Group, and co-chair Laird Popkin of Pando Networks. The group is sponsored the Distributed Computing Industry Association (DCIA). Yale University software experts worked on and monitored the project.

"The results of the testing have been phenomenal," said Pasko. "Customer and network benefits were seen as soon as the test began. This new system, which routes files along the fastest, least expensive path, offers our FiOS customers P2P downloads up to six times faster than networks without the overlay, the study showed. On average, download speeds using other Internet access technologies improve by about 60 percent."

According to Pasko, the end result of the experiment and ultimate implementation could be "carrier-grade P2P," once focused routing and handling replace arbitrary delivery paths. The system could cut P2P network delivery costs for participating network companies by as much as 50 percent.http://www.verizon.com
  • In February 2008, Pando announced NBC as its latest content customer.

  • Pando is funded by Intel Capital, BRM Capital and Wheatley Partners.

Comcast Conducts 100G Live Trial with Nortel

Comcast will conduct a test of Nortel's 100 Gbps line rate optical transmission solution at the 71st meeting of the Internet Engineering Task Force (IETF) conference, which it is hosting this week in Philadelphia.

The 100G solution runs over Comcast's existing fiber network. The test network is comprised of Comcast's existing Common Photonic Layer DWDM solution with 50GHz enhanced Reconfigurable Optical Add/Drop Multiplexer (eROADM) and photonic components, augmented with prototype 100G interfaces installed in Nortel's Optical Multiservice Edge 6500. The 100G cards utilize Nortel's 40G/100G Adaptive Optical Engine, with integrated dispersion compensation and dual-polarization Quadrature Phase Shift Keying (QPSK) modulation, the same technology used in Nortel's present 40G solution. The 100G trial runs from Philadelphia to McLean (Virginia), traversing Comcast's metro and long-haul fibers.

The companies said Comcast's network trial will be first time real traffic is run over a 100G wavelength on its existing network. The network also carrying live 10G and 40G links. The trial will run in parallel over the same optical infrastructure that supports a combination of high definition or HD video, Internet and voice traffic on Comcast's 40G national backbone network.

"Testing an interoperable multi-vendor 100G solution will help provide us with important information about how new solutions will support a next generation of high bandwidth services for the digital generation of consumers," said John Schanz, EVP National Engineering and Technical Operations for Comcast.http://www.nortel.com
