NTT Com Expands Cloud-based Traffic Analysis System for DDoS Attacks

NTT Communications is enhancing its overseas Global IP Network Service with cloud-based traffic analysis for distributed denial-of-service (DDoS).

The Global IP Network Service will be offered as an optional service via a dedicated web portal. Traffic on the customer's network is monitored 24/7 for DDoS detection and analysis. Any DDoS attack is reported promptly to the customer. The service also enhances network security by analyzing DDoS attacks to help the customer to protect their servers and routers against DDoS attacks. Trials conducted by NTT Com and volunteer companies found that this service can reduce the customer's DDoS monitoring and analysis operations by 75%.

The Global IP Network Service also analyzes traffic in terms of autonomous systems, IP addresses, ports, etc. Detailed reporting is available in graphical display format to help customers visualize their network traffic situation to better understand their needs for additional network enhancement. Trials conducted by NTT Com and volunteer companies found that this service can reduce related traffic analysis and reporting operations by 90% for customers.

NTT Com has been offering this service since 2009 in Japan. It will now be offered in Australia, France, Germany, Hong Kong, Malaysia, Singapore, South Korea, Taiwan, the Netherlands and the United Kingdom.

NTT Com also announced that it has upgraded its Equinix data center POP in Tokyo, and plans to launch a new PoP in @Tokyo data center on September 26.
  • NTT Com's Global Tier-1 IP backbone currently boasts 520 Gbps for U.S.-Japan traffic, 421 Gbps for Asia-Oceania, 77 Gbps for Japan-Europe and 100 Gbps for Europe-U.S.

Mindspeed Introduces Burst-Mode Transimpedance Amplifier for GEPON

Mindspeed Technologies introduced a 1.25 Gbps complement to its 10 Gbps Ethernet Passive Optical Network (10G-EPON) burst-mode receiver chipset that delivers a complete solution for GEPON/10G-EPON optical line termination (OLT) receiver equipment used in central office (CO) locations. The new 1.25 Gbps transimpedance amplifier (TIA) for CO-side OLT equipment can be used with the company's previously announced continuous-mode 1.25 Gbps TIA for subscriber-side Optical Networking Units (ONU) equipment, which creates an end-to-end solution for GEPON applications. Mindspeed also offers a receiver solution for next generation higher-speed 10G-EPON applications, consisting of its 10Gbps burst-mode TIA for OLT equipment. Each of Mindspeed's end-to-end solutions is also complemented by ONU and OLT laser drivers and post amplifiers to create complete solutions on each side of the link.

Reliance Globalcom Upgrades Asia Submarine Cable to 40G

Reliance Globalcom completed an upgrade of its FNAL submarine network using Ciena's coherent 40G optical networking solution. The enhanced network brings massive capacity increases to two key routes that each span approximately 5,000 kilometers to connect Japan, Taiwan, South Korea and Hong Kong. The first project is described as the first coherent 40G submarine network in Asia, adding approximately 4 terabits of aggregate capacity. THE upgrade is also believed to be the first submarine deployment with reconfigurable optical add-drop multiplexers (ROADM), which provide flexibility to add or drop select wavelengths at intermediate sites

Ciena provided its 6500 Packet-Optical Platform with 40G ultra long haul interfaces, which are designed to significantly increase submarine network capacity without disrupting existing customer traffic or adding cost and complexity to the network. Ciena also provided Deployment Services and quickly turned up the system with in-service traffic migration from existing 10G to coherent 40G.

Sprint Sues to Block Proposed AT&T and T-Mobile

Sprint filed its own lawsuit in federal court in the District of Columbia seeking to block AT&T's proposed acquisition of T-Mobile USA. Sprint cited Section 7 of the Clayton Act, arguing that the deal would hurt consumers, as well as Sprint and other independent operators.

TE Connectivity Launches Indoor Prism Distributed Antenna System

TE Connectivity introduced a new indoor version of its FlexWave Prism distributed antenna system for mobile coverage and capacity in enterprises, college campuses, and urban/suburban macro networks. FlexWave Prism IRU uses rack-mountable, indoor remote units and works with coax cable direct to service antennas. It supports 2G/3G/4G services with SISO or MIMO implementations, digital simulcast, a 26db optical budget, digital fiber transport and with high power amplifiers. It also incorporates 100 Mbps in-band Ethernet for carrying surveillance camera traffic, alarming, WiFi access points, or other applications.

RADWIN Intros P-to-MP for Licensed 3.x & 2.5 GHz Bands

RADWIN introduced its a high-capacity, Point-to-MultiPoint (HPMP) solution for the licensed 3.x GHz and 2.5 GHz bands. The platform allows operators who own WiMAX licenses to leverage these bands in order to deliver high capacity to the lucrative enterprise market and fulfill the unmet expectations from WiMAX.

The RADWIN 5000 HPMP delivers up to 100 Mbps aggregate net throughput per sector in these licensed bands, as well as dedicated bandwidth with guaranteed Service Level Agreement (SLA) and highest spectrum efficiency. It supports ranges of up to 40 Km/25 miles.

Adi Nativ, RADWIN's VP Marketing and Business Development, said: "Many operators obtained the 3.x GHz and 2.5 GHz bands in order to operate WiMAX systems, but in most cases these WiMAX systems can't meet the desired level of service that business customers demand. With RADWIN 5000, operators can leverage existing licenses to deliver high-quality, high-capacity service with strict SLAs. RADWIN 5000 is already successfully deployed worldwide in unlicensed sub-6GHz bands, and is rapidly becoming the preferred Point-to-MultiPoint solution of operators serving the enterprise market."

Rice University Researchers Develop Full-Duplex Wireless

Researchers at Rice University in Houston have developed a "full-duplex" technology with potential usage in 4G or 4.5G networks. The breakthrough promises to double total throughput in the network without adding new cell towers in the same frequency band, according to the university.

Building on theoretical work published last year, the researchers have now demonstrated signal quality at least 10 times better than any previously published result. The systems uses an extra antenna and a clever cancellation algorithm in the receiving end without requiring complex, new radio hardware.

"We showed that our approach could support higher throughput and better link reliability than anything else that's been demonstrated, which is a plus for wireless carriers," said Ashutosh Sabharwal, professor of electrical and computer engineering at Rice. "On the device side, we've shown that we can add full duplex as an additional mode on existing hardware. Device makers love this because real estate inside mobile devices is at a premium, and it means they don't have to add new hardware that only supports full duplex."

Rice is planning to roll its full-duplex innovations into its "wireless open-access research platform," or WARP. WARP is a collection of programmable processors, transmitters and other gadgets that make it possible for wireless researchers to test new ideas without building new hardware for each test. Sabharwal said adding full-duplex to WARP will allow other researchers to start innovating on top of Rice's breakthrough.

The research was funded by the National Science Foundation, the Roberto Rocca Education Program and Xilinx Incorporated.

Aviat Sells its WiMAX Business to EION Wireless

Broadcom Announces Full-Band Capture Digital Tuning for Satellite STBs

Broadcom introduced its Full-Band Capture digital tuning technology replaces multiple discrete tuners with one system-on-a-chip (SoC) for simpler, smaller, faster and lower power designs for the satellite TV market. Broadcom's FBC technology digitizes the entire 950-2150 MHz spectrum, allowing any demodulator to tune to any frequency and removing wideband "block" tuner restrictions for a more efficient distribution of video streams and IP services. The company claims a more than 50 percent reduction in power savings, as well as significantly faster channel change times.
