Alcatel-Lucent Integrates Arbor's Threat Management to Stop DDoS

Alcatel-Lucent is integrating Arbor Networks' Threat Management System into its 7750 IP Service Router to provide advanced distributed denial-of-service (DDoS) protection in carrier clouds.

Last year, Arbor Networks documented a single, sustained DDoS attack at up to 100G, making it essential that carrier clouds address this escalating challenge.

The partnership between Alcatel-Lucent and Arbor makes it possible to detect and eliminate DDoS closer to the edge of the network, before infected traffic is carried across the network to its target. By integrating Arbor’s Threat Management System (TMS) software into Alcatel-Lucent’s IP routers - wherever they are located in a given network - attacks can be detected and dealt with at the edge of the cloud, closer to the location of the attack, which is a much more effective and less costly approach.

The capabilities will be delivered either as a standalone appliance or running on an MS-ISA blade for the 7750 Service Router. The solution delivers
60 Gbps+ performance per chassis, which Alcatel-Lucent describes as "industrial strength DDoS scrubbing."

The approach also enables Service Providers to offer a cloud-based service to detect and mitigate DDoS attacks on the networks of their enterprise customers. Effectively, the DDoS scrubbing capability is extended to all customers, services and geographies serviced by the router.

Kevin Macaluso, Vice President and General Manager of the IP Service Router Product Unit at Alcatel-Lucent, said: “Denial-of-service attacks are a rapidly growing problem in service provider and Enterprise networks today. Unchecked, they can bring down large networks and data centers for significant periods of time, which obviously has a detrimental impact on productivity and delivery of services. By integrating Arbor’s TMS into our IP service routers, we’re essentially moving the defensive perimeter further out to the ‘edge’ of the service provider’s network – in effect stopping criminals at the border."

The combined solution is available today and is currently in trials with more than 20 service providers worldwide.

  • In Novermber 2011, Alcatel-Lucent introduced a new "CloudBand" architecture for delivering "virtual telco" functionality and enterprise services from cloud-enabled data centers rather than dedicated telecom platforms. CloudBand, which will be the foundation for a new class of ‘carrier cloud' services such as IMS or video applications, leverages generic compute resources deployed in regional data centers throughout a carrier's footprint. The goal is to make the carrier infrastructure more agile, elastic, resilient and application-aware.
  • In 2010, Tektronix Communications acquired Arbor Networks, a provider of network security and management solutions, for an undisclosed sum. Arbor Networks, which is headquartered in Chelmsford, Mass., supplies solutions for the detection and mitigation of network security threats based on IP flow-based analysis. Its products include Arbor Peakflow, a carrier-class Distributed Denial of Service (DDoS) prevention platform, and its Arbor eSeries platforms for broadband service optimization. Its customers include mobile and fixed-line operators, cable and DSL providers, ISPs and other cloud-based infrastructure and service providers.

PMC's OTN Switching Complies with New OIF Protocol

PMC-Sierra's HyPHY family of OTN processors provide full architectural support of the Optical Internetworking Forum (OIF)’s new OTN-over-Packet-Fabric Protocol Implementation Agreement (IA).

The OIF IA defines a method for switching OTN streams, including the newly standardized ODU0 and ODUflex streams, over cell or packet switch fabric technology. This enables Packet Optical Transport Platforms (P-OTPs) to be based on a single fabric, which results in significantly simpler designs that consume less power and shelf space.

PMC said its HyPHY 20G and HyPHY 10G OTN processors provide a fully compliant implementation of the OIF IA via the Constant Bit Rate Interface (CBRI) and OTN Phase Signalling Algorithm (OPSA). CBRI, which is compliant with the Interlaken protocol, enables HyPHY to connect to a centralized packet/cell switch fabric and is capable of supporting hybrid packet/OTN switched line card designs (see Figure 1). OPSA provides for the segmentation, reassembly and frequency/phase encoding/decoding required to support OTN over a packet/cell fabric. The HyPHY 20G handles up to 40Gb/s of multi-service line-side traffic via 16-SFP, 2-XFP/SFP+, and 2-SFI-4.1 interfaces. In addition to P-OTP OTN switching line card applications, HyPHY also enables single-chip, low-power multi-service OTN muxponder and transponder line cards.

ETSI Approves Open Smart Grid Protocol (OSGP)

ETSI, the European standards organization, published two specifications aimed at accelerating the deployment of Smart Grid technologies.

The two OSGP specifications that originated with ESNA and were published by ETSI for global use are:

Government Agencies Report GPS Interference by LightSquared

Last Friday, a committee of nine federal agencies and Cabinet level departments submitted a letter to the NTIA concluding that LightSquared’s proposed network would cause harmful interference to GPS. Critically, the FAA has found that interference from LightSquared would impact aircraft safety systems. In conclusion, the government investigators state "there is no practical solutions or mitigations that would permit the LightSquared broadband service, as proposed, to operate in the next few months or years without significantly interfering with GPS.�?

For its part, LightSquared issued a press release condemning the report and saying the testing "was rigged by manufacturers of GPS receivers and government end users to produce bogus results, and revealed details of the testing to document its accusations." LightSquared believes the GPS industry insiders and government end users manipulated the latest round of tests to generate biased results. Among the questions that LightSquared raises concerning the transparency and independence of the testing:

Why did the government choose to ignore LightSquared's proposed power levels?

Why did the government choose a power level 32 times greater than the level at which LightSquared will operate?

Why did the test protocol select the 1dB degradation to noise as the interference standard, since it does not apply to general purpose GPS receivers and GPS units are typically designed with an 8dB level of tolerance?

Who determined what acceptable interference is for the current round of testing? What is that standard?http://www.lightsquared.com

NTT Develops 60 GHz Transceivers Delivering 15 Gbps

Researchers at Nippon Telegraph and Telephone Corporation (NTT) announced the world’s smallest wireless transceivers that cover all four of the channels*1 allocated in the 60-GHz band.

The 60 GHz transceivers have a maximum transmission rate of 3.8 Gbps per channel. Simultaneous four channel transmissions makes the transmission rate about 15 Gbps.

NTT said the 60 GHz technology could be used in kiosks located in public venues that would wirelessly download of gigabyte-class content (e.g., a DVD of 4.7 GB) in about 10 seconds,

In Japan, as per the revisions to the Radio Act in September 2011, four channels without licenses can be used for such an application.

The miniaturized transceivers are packed in a wireless module in which a broadband antenna and MMICs are integrated in the multi-layer LTCC substrate. It can cover all four channels.

Crossbeam and Spirent Emulate More Than 1 Million Mobile Users

In tests conducted by EANTC, Crossbeam and Spirent Communications were able to emulate more than a million simultaneous mobile subscribers using their smartphones and tablets. The significance of the test is that the companies were able to simulate the effectiveness of network security devices and how they perform under real-world conditions.

Specifically, the test replicate the traffic loads that carriers experience at the mobile Internet gateway (Gi/SGi). Spirent's Avalanche plat form was used to emulate more than 1 million users concurrently accessing the mobile data network with their connected devices. The traffic was sent through a single Crossbeam X-Series X80-S platform running Check Point software, where it underwent a series of firewall and IPS (intrusion prevention system) inspections, as well as network address translation (NAT). The real-world traffic model included using a 95 percent majority of HTTP sessions representing a range of user profiles. In addition, email (SMTP and POP3) connections were emulated alongside Smart Phone OS over-the-air updates.

“With so much misleading information about security product performance and the unpredictability of threats and traffic demands, there has been no clarity around what to test for and what methodology to use,�? said Chet Gapinski, vice president, product development at Crossbeam. “Any single measurement, such as network throughput, is meaningless unless tested and measured in combination with other metrics under real-world conditions. We saw an important opportunity to work with Spirent and EANTC on a set of real-world tests to move the industry forward to provide more accurate, uniform guidance."

China Mobile and Clearwire to Hold Joint TD-LTE Device Testing

China Mobile and Clearwire, in conjunction with the Global TD-LTE Initiative (GTI), announced an agreement on common test specifications and joint interoperability testing (IOT) for TD-LTE devices in the global band configurations, including 2.3GHz to 2.7GHz. Plans call for establishment of 4G mobile broadband labs featuring a joint test platform and IOT environment for TD-LTE devices. The labs will allow for the evaluation and qualification of commercial TD-LTE devices simultaneously in the U.S., China, and other promising markets, using common testing methodology, equipment, and infrastructure.

The collaboration is expected to accelerate development of the TD-LTE device ecosystem, especially in multi-mode, multi-band LTE devices. The carriers said the expected availability of the Quad-Band LTE 2.3-2.7 GHz spectrum range, in addition to certain other bands like 1.9GHz, as well as FDD and TD-LTE mobility interactions, makes it an ideal global configuration for mass 4G marketing worldwide.

“The unmatched spectrum portfolio underlying Clearwire’s planned LTE network has the potential to deliver faster speeds and with greater capacity than any current or proposed 4G network in the United States,�? said Dr. John Saw, chief technology officer of Clearwire. “Close collaboration with global wireless leader China Mobile accelerates the development of multi-mode multi-band TD-LTE and LTE FDD devices and provides the common test specifications OEMs, ODMs, chipset vendors and other critical component manufacturers need to rapidly develop and commercialize products to serve this massive global marketplace.�?

“Converged with LTE FDD, TD-LTE has become the major global 4G technology for unpaired spectrum,�? said Mr. Li Zhengmao, Vice President of China Mobile. “Our goal is to build efficient, low cost common infrastructure and terminal for different global markets with different spectrum to support mobile internet. By closely working with global operators such as Clearwire, we could leverage the experience, expertise, and scale to achieve this goal. This is also the reason why we create GTI and promote it jointly�?.

Clearwire plans to conduct its TD-LTE common IOT in Phoenix, AZ and Herndon, VA. China Mobile’s testing will be carried out in Beijing and other TD-LTE trial cities.
  • In September 2011, China Mobile and Clearwire announced a collaboration to accelerate the development of TD-LTE devices. Specifically, the carriers will work jointly to further accelerate the time-to-market availability of high volume TD-LTE chipsets and devices that should be commercially available starting in 2012. In addition, the two companies will collaborate to enable worldwide data roaming among TD-LTE, FDD-LTE and other 2G/3G networks. Both carriers support the global 2.5 GHz spectrum band for 4G deployments along with many other operators around the world. To date, both China Mobile and Clearwire have conducted successful TD-LTE trials and tests using commercially available/production-ready TD-LTE devices from numerous vendors.

  • In August 2011, Clearwire confirmed its intention to deploy "LTE Advanced-ready" technology in its 4G network while restating its commitment to its existing 4G WiMAX network, which covers approximately 132 million people while serving 7.65 million retail and wholesale customers. The company expects to end 2011 with approximately 10 million 4G customers. Clearwire said the initial LTE deployment will target densely populated, urban areas of its existing 4G markets where current 4G usage demands are high. Clearwire said its LTE network will be "LTE Advanced-ready," meaning that it will use spectrum configurations capable of 100+ Mbps downlink speeds.

Procera Launches 100G Intelligent Policy Enforcement

The PacketLogic 20000 boasts a capacity of 320Gbps per system and up to 5 Tbps per cluster, with support for up to 72 ports of 10GE and four ports of 100GE interfaces. The PL20000 is a 14/15RU AC/DC combination system.It supports up to 10 million active subscribers and 120 million active flows, with the ability to enforce services and collect charging information on every active flow in the system.

The new system is designed to work Procera’s PacketLogic Subscriber Management System to rapidly create innovative, sticky service offerings based on business analytics provided by the PacketLogic Report Studio. The PL20000 supports a full suite of policy enforcement capabilities, from content-aware service, congestion management, traffic prioritization, application-layer shaping, volume-based shaping, traffic steering and/or mirroring, and captive portals

Procera said one of its key differentiators is to provice radically simple tools to enable service providers to create personalized services – from the analytics tools of PacketLogic Report Studio to the customer-defined Virtual Services, plus easy-to-create charging and service policies on the PacketLogic Subscriber Manager. The goal is to enable operators to create and define services on-the-fly, without requiring signature updates or new software.

“As consumers continue to be more dependent on their broadband connections, the stress on broadband networks will continue to grow. Even though the PL20000 system performance shatters industry benchmarks, the biggest leap forward for the PL20000 is the ability to utilize the solution for personalized service creation at a scale never before possible for broadband operators of all types,�? says Cam Cullen, VP of Global Marketing for Procera.

The PL20000 will be available in Q2 2012 for customer shipments.

Sensory Networks introduces DPI Software for Low-end Device Market

Sensory Networks has extended and optimized its "HyperScan" pattern matching and deep packet inspection (DPI) acceleration software to provide high-speed content inspection on a range of low-cost, low-power processors used in networking and security products. The HyperScan pattern matching software has now been optimized for Intel Atom, Broadcom MIPS and ARM architectures. The DPI technology can now be extended to SMB and SOHO products that include Wi-Fi routers, Firewalls, IPS/IDS, UTM appliances and other network access devices.

“We now have several customer engagements where HyperScan is being used for DPI in low-end and ultra low-end devices, said Sab Gosal, CEO for Sensory Networks. “The low-end market segment has become so cost sensitive that equivalent hardware solutions simply cannot meet the price/performance requirements.�?

"HyperScan scales well to this class of device, delivering 400-500Mbps of scanning throughput per core, for a range of IPS and Anti-Virus use-cases, using a 1.6GHz Intel® Atom™ 230 processor", said Geoff Langdale, CTO of Sensory Networks. "Content inspection throughput improvements on resource challenged machines are only one part of our advantage. We have also aggressively reduced compiled byte code size and provided the ability to serialize and cross-compile pattern databases across different architectures. This ensures that it is practical to use our DPI technology for devices with very low provisioning of memory, storage and CPU cycles".
