FBI Makes Key Arrests in LulzSec Case

Five computer hackers in the United States and abroad were arrested and charged with crimes ranging from computer hacking conspiracy, fraud, conspiracy to commit access device fraud, conspiracy to commit bank fraud, aggravated identity theft and other offenses. Those arrested include principle members of "Anonymous" and "LulzSec".

In addition, Hector Xavier Monsegur, also know as "Sabu", "Xavier DeLeon", or "Leon", pled guilty on August 15, 2011 in U.S. District Court to a 12-count information charging him with computer hacking conspiracies and other crimes. His testimony is believed to have led to the arrest of the other members of LulzSec.

Between December 2010 and June 2011, LulzSec claimed responsibility for a series of brazen cyber attacks, including denial of service (Do�?) attacks against the websites of Visa, MasterCard, and PayPal, as retaliation for the refusal of these companies to process donations to Wikileaks, as well as hacks or DoS attacks on foreign government computer systems. Since then, the attacks have continued under other representations.

Alcatel-Lucent Pushes Ahead to 400 Gbps

Alcatel-Lucent unveiled its Photonic Service Engine (PSE), a new chip for coherent optical networking that supports data rates of 400 Gbps.

The new chip, which is being demonstrated at this week's OFC/NFOEC Conference in Los Angeles, brings substantial improvements to 100G optical coherent networks while laying the foundation for 400 Gbps line rates. The faster silicon enables far superior processing for a number of key optical functions, including coherent Tx and Rx, ultra-fast ADC/DAC, more complex modulation schemes, and new soft decision forward error correction (FEC).

Alcatel-Lucent said its 400G PSE chip can be deployed in a broad range of network configurations - from metro to regional to ultra-long haul - and transmit wavelengths over existing or new photonic lines. It is designed specifically for use in a family of line cards in the Alcatel-Lucent 1830 Photonic Service Switch (PSS). Specifically, the company is planning to use the PSE in a 100G muxponder card, a 100G transponder and a 100G backplane uplink. Alcatel-Lucent is also pushing ahead with a 400G line card for the 1830 Photonic Service Switch.

Alcatel-Lucent noted that its PSE was the enabling technology behind a record breaking optical transmission test performed by Deutsche Telecom’s Innovation Laboratories (T-Labs).
  • In June 2011, Alcatel-Lucent unveiled its 400 Gbps, "FP3" network processor for enabling the full stack of services over IP routers. The FP3 processor, which is scheduled to appear in Alcatel-Lucent's service router portfolio in 2012, supports 400 Gbps line rates, sufficient for handling 70,000 simultaneous High Definition video streams. It leverages 40nm process technology and represents the evolution of the company's 100 Gbps FP2 silicon, which was introduced in 2008 using 90nm process technology. It packs 288 RISC cores operating at 1 GHz. This compares with 112 cores at 840 MHz in the previous generation FP2 device. The new design uses 50% less power per bit than its predecessor.

    Alcatel-Lucent describes the FP3 as an engineering achievement that will anchor the next wave in bandwidth-intensive Internet growth. In particular, the new silicon enables high densities of 10G, 40G and 100G ports on a single card. The plan is to deliver FP-3 based line cards for the 7750 SR and 7450 ESS platforms in 2-port 100GE, 6-port 40GE, and 20-port 10GE configurations in 2012. However, the flexibility of the design paves the way for other configurations, including 4x100G cards or native 400G interfaces. It also opens the door to scale routers with terabit class slots.

    The FP3 also breaks new ground in that it enables the same full-services intelligence for core routers as has previously been possible at the metro or edge router.

Sensory's Pattern Matching Pushes DPI to 160 Gbps

Sensory Networks announced a new benchmark for its pattern matching software for accelerating deep packet inspection (DPI) platforms.

Sensory's HyperScan library has delivered DPI throughput of 160Gbps with linear scalability, based on an intensive benchmark of HyperScan on a dual-socket platform (8-core, 16 threads per socket) using the new Intel Xeon processor E5-2600 family and Intel C604 chipset, scanning against a tier-1 commercial IPS signature set. HyperScan fully scales across Intel architecture, extending from the Intel Atom™ processor to the highest performing Intel Xeon processor.

"This is the latest in a series of HyperScan benchmarks we’ve published that validates our strategy: to use software to transform processor real estate into scalable security performance�?, said Sab Gosal, CEO for Sensory Networks. “HyperScan is a pattern matching library designed to drop into a vendor’s system software release and be used for an entire product line, without requiring any additional software or hardware resources. This type of streamlined integration and scalability presents a compelling proposition for equipment manufacturers looking to build out DPI."

"This benchmark represents a significant leap forward in HyperScan performance�?, said Geoff Langdale, CTO for Sensory Networks. "We reported 32Gbps on the Intel Xeon processor E5400 series (Harpertown) when it was first released, using the same benchmarking setup and then 73Gbps on the Intel Xeon processor E5500 series (Nehalem). Continued advances in HyperScan’s scanning algorithms, coupled with underlying improvements in Intel micro-architecture and core count, have helped push our DPI throughput by a factor of 5 within just 3 years. We expect this performance scaling to continue as new architectures emerge in the coming years."

Infinera Lands Cable&Wireless Worldwide for its New DTN-X Multiterabit

Cable&Wireless Worldwide (CWW) will deploy Infinera’s new DTN-X platform for its Europe Persia Express Gateway (EPEG) network. The selection represents a major win for Infinera and its multi-terabit class Digital Optical Network solution with super-channel capability.

Cable&Wireless Worldwide's forthcoming EPEG network will provide geographic diversity and high-capacity for network traffic between Europe, the Middle East and India. Currently, the majority of traffic traverses fiber running through the Suez Canal and the Red Sea. The route could be a single point of failure impacting multiple cable systems should a natural disaster or manmade event occur in this narrow channel.

EPEG will stretch approximately 10,000 kms from Frankfurt in Germany to Oman with the unique attribute of having only 246 kms of undersea cable and all other routes terrestrial. Cable&Wireless Worldwide has a number of partners collaborating on this project.

CWW’s multiterabit EPEG optical network will use Infinera’s Digital Optical Network solution, powered by Infinera’s DTN-X, which includes the latest 500 Gbps photonic integrated circuits (PICs). The Infinera DTN-X delivers 500 Gb/s FlexCoherent super-channels and is upgradeable to 1 Tbps super-channels in the future, providing scalability with investment protection. The platform integrates 5 Tbps of OTN switching which will enable CWW to efficiently converge layers of the network resulting in reduced capital and operational expenses. Furthermore, Infinera’s intelligent GMPLS automation software will enable CWW to rapidly provision highly-reliable low-latency services, including 100 Gbps Ethernet, making it highly competitive across the Europe to Asia route.

“We believe that the Europe Persia Express Gateway is an important international network development as it will be providing high capacity, diverse connectivity from the Middle East Region to Europe," said Rick Perry, vice president international planning at Cable&Wireless Worldwide. "Infinera's solution is helping to underpin that development."
  • In September 2011, Infinera introduced its third generation, 500 Gbps photonic integrated circuit (PIC) -- the foundation for its new DTN-X multi-terabit switching platform designed for scaling core networks. The 500 Gbps PIC integrates more than 600 optical functions and works by converting light waves into electrical circuits, which can then be switched and groomed with digital signal processing.

    The DTN-X combines three core functions-- a) a DWDM transmission system, offering 500 Gig super-channels based upon 100 Gig coherent channels, b) an OTN switch that scales from 5 Tbps non-blocking at ODU 0 today to 100-terabit non-blocking in the future; and c) a platform that can be upgraded to MPLS in the future.

    Infinera believes that these key innovations will lead to the next economic disruption in the network, as very large pools of bandwidth can now be easily created, directed and managed across a fiber network. The 500 Gbps super-channel capability is unique in the industry and Infinera plans to support 1 Tbps super-channels in the future with another new PIC which is already in the lab.

    The DTN-X combines PICs, custom ASICs and GMPLS software to deliver 5 Tbps of non-blocking, ITU G.709 Optical Transport Network (OTN) switching in a single bay for grooming traffic onto larger 100 Gbps and 500 Gbps pipes to maximize network utilization. Future iterations of the platform will be upgradeable to resilient multi-bay configurations providing 100 Tbps of non-blocking OTN and MPLS switching.

    The embedded GMPLS software provides automatic topology discovery an inventory management. It also enables point and click end-to-end service provisioning, as well as <50ms hardware based protection for mesh & ring configurations.

    The new DTN-X is interoperable with Infinera's existing DTN platform and is planned to support 10 Gigabit Ethernet (10 GbE), 40 Gigabit Ethernet (40 GbE), 100 Gigabit Ethernet (100 GbE), 10 Gbps SONET/SDH/OTN, 40 Gbps SONET/SDH/OTN, 100 Gbps OTN, 8/10 Gbps Fibre Channel, and multiple bit rate clear-channel interfaces.

Polatis Debuts 192x192 Optical Matrix Switch

Polatis, a start-up based in Andover, Mass., unveiled its new Series 6000 Optical Matrix Switch - a fully non-blocking, all-optical singlemode fiber cross-connect for up to 192x192 fiber ports with less than 1dB typical optical loss. The new optical switch could be used in a range of applications ranging from secure government communications to data center virtualization, broadcast video distribution, satellite RF/optical link management, network testing.

Polatis features a unique, patented DirectLight beam-steering technology which uses piezoelectric actuators to connect light directly between switch ports to achieve the best possible optical performance independent of the color, direction or power level of light on the fiber path.

The new Series 6000 doubles the maximum matrix size previously available from Polatis (96x96 ports). The modular design of the Series 6000 allows both symmetric (NxN) and asymmetric (MxN) matrix configurations as well as a versatile customer-configurable option allowing any-to-any fiber connections. The switch can also be used to enhance network availability by enabling fast automatic recovery from network equipment or fiber failures. The Polatis DirectLight technology allows optical connections to be established with or without light on the fiber, enabling pre-provisioning of dark fiber paths for disaster recovery, M:N protection switching, and intelligent network monitoring and test.

Production shipments commence in the second quarter of 2012.

Polatis is showing the switch at this week's OFC/NFOEC 2012 exposition in Los Angeles (booth #915).
