Overture's Ensemble Open Service Architecture Looks to SDN

Overture unveiled its Ensemble Open Service Architecture aimed at transforming the metro edge with software-defined networking (SDN) and network function virtualization technology.

Overture, which supplies Carrier Ethernet solutions for the metro edge, said its goal is to transform static infrastructure into dynamic, virtualized, and automated environments for service creation and delivery.  This would let Service Providers offers virtualized network capabilities and application-aware cloud offerings to their enterprise customers.  In addition, by simplifying and automating essential tasks in service creation, activation, and assurance, Overture aims to significantly reduce the ongoing operational expenses of the network.

“Service providers do not have a demand problem – they have a revenue and cost problem. They are working to transform their bandwidth business into one focused on the customer application experience while dramatically driving down the cost of managing their infrastructure. With Ensemble OSA, we are helping service providers achieve both objectives by bringing the proven benefits of the cloud to the metro edge,” said Mike Aquino, president and CEO, Overture.

Overture's Ensemble OSA will leverage open API standards, including OpenFlow.  It is comprised of three layers, each of which may include Overture developed components and those developed by service providers or third party vendors:

  • Resources – Elements that provide connect, compute, and storage functionality. They may consist of physical devices such as switches, servers and storage arrays, and/or software functions running on virtual machines.
  • Orchestration and Control – Software building block functions for data plane control, resource abstraction, and network management that provide the glue connecting the resources to the applications.
  • Network Applications – Software packages that leverage one or more of the Orchestration and Control building blocks and tie into a service provider’s back office systems and that of their business partners to create a service or network function.

Overture is currently building out ecosystem partnerships, and integrating the APIs into the initial set of Ensemble-powered Overture equipment. The company expects Ensemble OSA products, integrated with third-party applications and devices, to be available to the general market in 2014.

RootMetrics: AT&T LTE Averages 18.6 Mbps, VZ Wireless Averages 14.3 Mbps

AT&T has the fastest LTE performance among U.S. networks, according new data published by RootMetrics, an independent mobile analytics firm. The report is based on more than 725,000 4G and 4G LTE data samples gathered from the top 77 U.S. markets during the second half of 2012.

Some key findings:

  • AT&T's LTE-only achieved 18.6 Mbps average downloads (57.7 Mbps max) and 9.0 Mbps average upload (19.6 Mbps max).
  • Verizon's LTE-only achieved 14.3 Mbps average downloads (49.3 Mbps max) and 8.5 Mbps average upload (19.7 Mbps max).
  • Sprint's LTE-only achieved 10.3 Mbps average downloads (32.7 Mbps max) and 4.4 Mbps average upload (9.9 Mbps max).
  • T-Mobile USA's HSPA+42 service achieved 7.3 Mbps average downloads  and 1.5 Mbps average upload (9.9 Mbps max).

RootMetrics notes that Verizon commands the most extensive footprint and the best chance of connecting to LTE in markets that LTE-ready.

Czech Telecom Authority Halts Spectrum Auction Because Bids too High


The telecom regulatory office for the Czech Republic halted an ongoing auction for 4G spectrum in the 800 MHz, 1800 MHz and 2600 MHz bands because bidding exceeded the threshold limits for the auction.

The Czech Telecommunication Office said the upper pricing limits for the spectrum was set after observing the experience of other EU member states where high license prices were achieved, thereby benefiting the government, but resulting in a distorted telecom market where carriers are reluctant to deploy quickly.  As a consumer issue, the Czech Telecommunication Office said high spectrum prices would most likely translate into high prices for mobile services.

Seacom Upgrades African Cables with Ciena


Seacom, which operates submarine cables systems along the coasts of Africa, has selected Ciena's 6500 Packet-Optical Platform and OneControl Unified Management System for the upgrade of its infrastructure.

The upgrade, which includes key countries in SEACOM’s 17,000km undersea network, including India, Egypt, Dijbouti, Kenya, Tanzania, Mozambique, and South Africa, will initially use Ciena’s 40G coherent transport technology, with ultra-long distance 100G wavelengths planned for future upgrades.

DragonWave Debuts Compact, Sub-6 GHz Microwave Radio


DragonWave unveiled an all-outdoor, sub-6 GHz microwave radio for rural deployments, government and private networks, vertical industries, mobile and extended network backhaul.

The DragonWave Harmony Radio Lite offers a form factor of only 7.5 in square including integrated antenna.  Its point-to-point microwave radio supports both licensed and unlicensed spectrum and is ideally suited for non-line-of-sight (NLOS) scenarios. It includes standard Ethernet interfaces. Streamlined functionality is further complimented by low power consumption (under 15W), PoE compatibility, reduced cabling requirements and low delay. Synchronization through 1588v2 and SynchE eliminates the need for an external synchronization source.

Harmony Radio Lite links can be deployed using a tree topology, with macrocell traffic aggregation points on rooftops, or with tail, chain or small hub microsites at street level, which reduces interference and offers more flexible network connectivity, as well as simplifying network expansion and helping to ensure protected network architectures.

"Addressing vertical markets and a growing demand for rural and suburban backhaul has driven our product strategy with the introduction of the Harmony Radio Lite,” said Peter Allen, CEO. “The value proposition customers seek is Quality of Service assurance, affordability and ease of deployment and management of the network ­– we’re confident the Harmony Radio Lite raises the bar by bringing the lowest cost per bit with uncompromised performance."

Crehan: Data Center Ethernet Switch Market Hits $8 Billion Run-Rate

Data center Ethernet switch revenues exceeded $2 billion in calendar 4Q12, putting this market on an $8 billion annual run-rate, according to a new report from Crehan Research.

The report shows that calendar 2012 revenue growth far exceeded that of 2011, helped by a leveling out in the decline of Chassis/Modular Ethernet switch shipments, coupled with increasing adoption of 10 Gigabit Ethernet (10GbE) switches.

“Given that data center Ethernet chassis or modular switches command a considerable price premium over the market average, mix shifts in this segment can have a significant market impact,” said Seamus Crehan, president of Crehan Research. “Aided by stabilization in the mix of this data center Ethernet switch category, total market average selling prices fell only a little in 2012,” he added.

Two other highlights from the report:

  • Data center Ethernet Fixed/Top-of-Rack switches continue to reach record levels, as this form-factor not only sees increasing server access deployment, but also data center aggregation deployments.
  • In line with the overall market, Fibre Channel Switches also enjoyed revenue growth in 4Q12 and 2012, as higher pricing offset port-shipment declines.

Dell'Oro: Microwave Transmission Market Declined 12% in 2012


The point-to-point Microwave Transmission equipment market declined 12 percent worldwide in 2012 to $4.2 billion as radio transceiver shipments declined 6 percent to 1.5 million, according to a new report from Dell'Oro Group.

"The market for microwave backhaul was truly impacted by surprisingly low demand in the European region," said Jimmy Yu, Vice President of Microwave Transmission research at Dell'Oro Group.  "Although the market really took a step back this year, there were a couple of bright spots.  The first was the growth in sales in the North American region as operators expanded their Long Term Evolution (LTE) networks.  The second was the greater usage of ultra-high-capacity links using E-band frequencies to deliver a full gigabit of backhaul capacity to cell towers," Yu added.

Some highlights:

  • The North American region was the only region to achieve significant positive growth in 2012, growing 13 percent.  Alcatel-Lucent captured the majority of the North American market, garnering 44 percent market share.
  • Microwave sales in the European region pulled back sharply in 2012, declining 28 percent.  Ericsson held the highest share of the European market at 32 percent.
  • Ultra-high-capacity radio transceiver shipments grew nearly 60 percent in 2012.
