An Update on Verizon's 100G Network - New Routes 2012

Verizon provided an update on its 100G network rollout.  In 2012, the carrier added 20,921 additional kilometers (13,000 miles) of 100G routes in the U.S. and 2,600 kilometers (1,616 miles) in Europe.

Verizon said it is adding 100G on selected routes in the U.S., where traffic demand is highest, including Atlanta to Tampa, Kansas City to Dallas and Salt Lake City to Seattle, using the same routers and coherent optical transport equipment as on the company’s first 100G routes deployed in 2011.

 In Europe, Verizon added 100G routes between London and Paris, and London and Frankfurt.  Verizon already had 100G running on the  Frankfurt-to-Paris route. This creates a 100G ring that spans more than 2,600 kilometers.

"Expanding 100G technology on our high-performance U.S. and European networks means Verizon is able to successfully meet traffic demand while increasing efficiency and capacity,” said Kyle Malady, senior vice president of global network operations and engineering for Verizon. “Increased video traffic, LTE 4G growth and cloud usage are driving bandwidth demand and 100G is critical to creating that rich end-user experience."

Bell Labs: Internet Video to Push Networks to their Limit

Driven by tablet usage at home and on the go, consumers in the United States alone will access seven hours of video each day – as opposed to 4.8 hours today, according to a new study from Bell Labs.  The research points to a dramatic shift in viewing habits, as consumers switch from broadcast content to video-on-demand services, which will grow to 70% of daily consumption compared with 33% today.

Some highlights of the 16-page report:

• The proportion of time spent watching managed video-on-demand services and web-based video will grow from 33% to 77%. This will come at the expense of traditional broadcast TV services, whose relative share of time will drop from 66% to 10%.
• Internet-based video consumption each year will grow twelvefold, from 90 Exabytes to 1.1 Zettabyes.
• Consumption of managed video-on-demand from services providers versus OTTs is expected grow at 28 percent annual rate, from 44 Exabytes to 244 Exabytes.
• 10.5% of managed video consumption and 8.5% of OTT video consumption will occur at the peak hour, 8:00 p.m.

Bell Labs is warning that this shift to unicast distribution will put disproportionate pressure on the IP edge of broadband networks.

"Delivery of video from the cloud and from content delivery networks to tablets, TVs and smartphones - with guaranteed quality -, presents an exciting new revenue opportunity for communications service providers, but only if they are prepared to take advantage of it. Left unmanaged, the rapid growth in video traffic can turn into a deluge and spell disaster. It is important to look at where service providers’ investments can have the most impact, and this research makes clear that the IP edge of both wireline and wireless networks – which are increasingly becoming one and the same - offers the greatest opportunity to improve network performance. At the same time, it also presents the greatest source of risk if not managed appropriately,” stated Marcus Weldon, Chief Technology Officer, Alcatel-Lucent.

NSN Demos Core Virtualization and Cloud Management

Nokia Siemens Networks reports progress in its efforts to bring virtualization and cloud management to the core of mobile networks.

A recent proof of concept project conducted with a leading global operator demonstrated that core virtualization and cloud management are viable technologies.

Nokia Siemens Networks said the goal is to allow the core network, comprising the packet-switched, circuit-switched and IP Multimedia Subsystem (IMS) domains, to run on a common resource pool of generic multipurpose hardware.

The cloud prototype developed by Nokia Siemens Networks incorporates network elements such as an MSC Server (MSS), Mobility Management Entity (MME), Call Session Control Function (CSCF) and Telecom Application Server (TAS) into a virtualized infrastructure running on commercial off-the-shelf (COTS) hardware based on Advanced Telecommunications Computing Architecture (ATCA) or any other commercially available IT server platforms depending on the operator’s preference. The virtualized network elements and cloud framework are integrated into NetAct, which provides an end-to-end view of the status of the virtualized network, as well as managing all Nokia Siemens Networks core network products.

“With the explosion of data traffic created by the popularity of smart devices and new high-definition (HD) voice and video, core networks must deliver virtually unlimited scalability, flexibility and efficiency with superior customer experience”, said Michael Clever, head of Voice and IP transformation at Nokia Siemens Networks. “Identifying concepts for adapting telco network capacity and service management in the cloud will help operators understand the advantages of telco cloud technologies and the power of virtualization.”

FCC Proposes 100 MHz of Shared Spectrum for Small Cells in 3.5 GHz Band

The FCC is proposing to make available 100 megahertz of shared spectrum in the 3.5 GHz Band (3550-3650 MHz) for small cell deployments.

The FCC said it envisions three tiers of users, each with different levels of rights and protections in the 3.5 GHz Band:

• The first tier, Incumbent Access, would include authorized federal users and grandfathered fixed satellite service licensees. These incumbents would be afforded protection from all other users in the 3.5 GHz Band.
  
• The second tier, Protected Access, would include critical use facilities, such as hospitals, utilities, government facilities, and public safety entities that would be afforded quality-assured access to a portion of the 3.5 GHz Band in certain designated locations.
  
• The third tier, General Authorized Access, would include all other users – including the general public – that would have the ability to operate in the 3.5 GHz Band subject to protections for Incumbent Access and Protected Access users. 

A spectrum access system, incorporating a geo-location enabled dynamic database, would govern access to the 3.5 GHz Band.

The President’s Council of Advisors on Science and Technology (PCAST) issued a
report this summer recommending spectrum sharing and small cell use in the 3.5 GHz Band.

http://www.fcc.gov/document/fcc-proposes-innovative-small-cell-use-35-ghz-band

The PCAST Report - July 2012

U.S. federal policy should shift in favor "Shared-Use Spectrum Superhighways" instead the current plan which is to first clear federal users from specific bands and then auction this spectrum for the exclusive use of the highest bidder, according to a new report issued by the President’s Council of Advisors on Science and Technology (PCAST). The report identifies 1,000 MHz of federal spectrum for sharing with the private sector.

The New Spectrum Superhighway plan (1) divides spectrum into substantial blocks with common characteristics (2) makes sharing by Federal users with commercial users the norm (3) measures spectrum effectiveness using a new metric (4) increases capacity by "1,000’s of times." 

A Presidential memorandum issued in June 2010 requires that 500 MHz of spectrum to be made available for commercial use within 10 years.  However, a recent NTIA Study found that clearing just one 95 MHz band will take 10 years, cost $18 billion, and cause significant disruption. Moreover, the net revenue for the Treasury from the last successful auction of 45 MHz realized a net income of just a few hundred million a year ($5.3 billion total).

The PCAST report said its vision of shared spectrum is viable using existing technologies and is not dependent on cognitive or "smart" radios. Instead, a geo-location database could be used the share spectrum much like how the FCC is using managing TV bands. The TV Whitespaces system could be used as a model. Technical standards would need to be implemented for coexistence of transmitters and receivers to enable flexible sharing.

To get things rolling, the PCAST report recommends that an incentive mechanism be created to encourage Federal agencies to begin sharing (e.g., Spectrum Currency). The existing Spectrum Relocation Fund, which is supposed to fund the migration of federal users out of certain bands, could be redeveloped into a "Spectrum Efficiency Fund." The system could be tested in a specific city before being extended nationwide.

The 192 page report is posted online.

Applications can run without modification in the cloud and continue to access services that reside in the enterprise data center.

The company has demonstrated full server, networking, security and storage integration with AWS, a key enterprise requirement for complex, multi-tier applications in any cloud.  CloudVelocity plans to integrate other public clouds in 2013.

Cloud Velocity has now opened beta trials to its Developer Edition cloud cloning software, which allows users to quickly and safely clone multi-tier app clusters and services, without modification into the Amazon Web Services (AWS) EC2 cloud. The company is also offering an Enterprise Edition beta trial that enables users to clone, migrate and failover multitier apps and services into the AWS EC2 cloud.

CloudVelocity, which was previously known as Denali Systems while in stealth mode, recently closed $5 million in Series A funding from Mayfield Fund.  The company's co-founders include Rajeev Chawla (formerly CEO of NeoPath Networks, which was acquired by Cisco), Anand Iyengar (formerly CTO at NeoPath), Panor Tsirigotis (formerly Chief Software Architect at NeoPath), and Raman Chawla (formerly Senior Director of Engineering at NeoPath).


"Mayfield Fund has a 43- year history of successful incubations, where we partner with
entrepreneurs at the idea stage and help create a company that tackles big problems and
CloudVelocity is another example of this" said Navin Chaddha, Mayfield Fund Managing
Director.  "We believe that CloudVelocity will have the same impact on public cloud adoption
as VMware did on the adoption of server virtualization by making public clouds look like
internal data centers."

Cisco Targets Converged Cable Access with new CMTS Line Cards and Processing Blade

Cisco is building its Converged Cable Access Platform (CCAP) architecture with a new high-density line card and a new high-performance processing engine for its flagship Cisco uBR10012 Universal Broadband Router (uBR10K) and Cisco Cable Modem Termination System.

CCAP is a new cable access architecture backed by CableLabs that combines the functions of two key technologies: the cable modem termination system (powers DOCSIS and other high-speed broadband services) and edge QAM (powers video services). Combining the two functions helps service providers reduce rack space, save power, and accelerate the transition to an all-IP network that can simplify the delivery of video content to multiple screens.

Cisco's new Performance Routing Engine (PRE5) and 3 Gigabit Shared Port Adapter (3GSPA) effectively double the number of downstream channels available for the uBR10K, from a total of 576 to 1,152, without needing any additional rack space. The PRE5 quadruples the chassis capacity to 40+ Gbps. Up to eight 3GSPA line cards can be used per Cisco uBR10K CMTS. Each 3GSPA card can support up to 72 downstream licenses per port.

Cisco said its new modules will allow cable service providers to make better use of their existing platform, while adopting an incremental deployment approach to using more ports, with a pay-as-you-grow business model. Trials are expected to begin in Q1 2013.

Fujitsu, NTT and NEC Target 400G Coherent Optical Transmission

Fujitsu, NTT and NEC are jointly developing 400 Gbps/channel-class digital coherent optical transmissions technology.

The companies have undertaken a joint R&D project that aims to leverage the technological capabilities that have enabled the commercialization of 100Gbps-class optical transmission. The R&D initiative was commissioned and is sponsored by Japan's Ministry of Internal Affairs and Communications (MIC) as part of the "Research and Development Project for the Ultra-high Speed and Green Photonic Networks".

Specifically, Fujitsu, NTT and NEC have pursued R&D on 100Gbps-class digital coherent optical communications technology as part of the MIC's "Research and Development on High Speed Optical Transport System Technologies" program (2009) and "Research and Development on Ultra-high Speed Optical Edge Node Technologies" program (2010-2011).

As a result of the previous research, a digital coherent DSP-LSI was commercialized in 2012 and is now being being deployed by each company. The new initiative will accelerate this work for 400Gbps-class optical transmissions.

The joint research project is targeting dual-polarization quadrature phase shift keying (DP-QPSK)(3), which is currently in use for 100Gbps transmissions, together with dual-polarization 16 quadrature amplitude modulation (DP-16QAM), which takes advantage of an even greater number of quadrature carriers.

The companies said that by incorporating these modulation techniques into a high-density 60-channel fiber, the technology will be able to bring about optical networks capable of 24 Tbps/fiber.  The goal will require development of the first compensation technology for nonlinear optical effects within an optical fiber.  This is the primary limiting factor standing in the way of long-distance transmission of multiple quadrature modulated signals. When employed together with enhanced-performance versions of existing compensation technologies for chromatic dispersion and polarization mode dispersion, the new technology will achieve longer transmission distances.

The companies will pursue the implementation of adaptive modulation/demodulation technology that can employ a host of modulation techniques depending on the transmission route using a single hardware device, thereby leading to the construction of flexible network
