SureWest Communications Integrates Accedian Networks’ MetroNID® Performance Assurance Platform in its Wireless Carrier Backhaul Service

Integrated service monitoring and performance management lets SureWest meet the needs of wireless operators with high quality backhaul services.

June 23, 2010, Light Reading Mobile Strategy Conference New York – Accedian Networks, the market-leading developer of Carrier Ethernet Performance Assurance Network Interface Devices (NIDs) and service management solutions, today announced that SureWest Communications (NASDAQ: SURW) is deploying Accedian Network’s Performance Assurance Platform to ensure high quality service delivery for its Wireless Carrier Backhaul Ethernet-based mobile backhaul service.

SureWest conducted an extensive evaluation of performance monitoring solutions before selecting the Accedian MetroNID® for integration into the network. “The Accedian solution provided us the best performance assurance system to meet our customers’ needs,” said Ken Johnson, SureWest’s Vice President and General Manager of Operations. “We chose a solution that enables us to deliver the highest quality mobile backhaul services to our wireless operator customers. But we also selected one that we can seamlessly integrate across our entire Carrier Ethernet service portfolio, and the Accedian Performance Assurance Platform gives us that flexibility.”

The explosive growth of smart phones and mobile broadband devices, coupled with the deployment of next generation mobile broadband applications, is creating a demand for bandwidth that simply cannot be met using the legacy mobile backhaul networks. Existing wireless backhaul networks originally designed for voice have a typical capacity of 1-3 Megabits per cell site and do not accommodate the onslaught of broadband data traffic, where mobile operators are seeing demand for 10-50 Megabits per cell site. SureWest’s fiber- and Ethernet-based networks in both the greater Sacramento and Kansas City regions are more than sufficient to meet this demand.

SureWest’s Wireless Carrier Backhaul is an Ethernet-based service that provides the capacity and performance needed for wireless operators to effectively deliver mobile broadband services. Delivering Ethernet mobile backhaul services can be challenging as the mobile network demands precise service quality. Monitoring latency, packet delay variation, packet loss and availability of mobile backhaul services is critical to successfully meeting the wireless operators’ needs and requires robust performance assurance to ensure that the mobile backhaul network meets these needs around the clock.

Before deploying the MetroNID®s in its network, SureWest compared them against a number of alternatives. The decision criteria included not only performance assurance monitoring and reporting features, but SureWest also compared performance, interface density and power consumption. All aspects for deploying the most efficient service performance infrastructure were evaluated. “Accedian is proud to be working with such a recognized innovator,” said Craig Easley, Accedian’s VP of Marketing. “We were confident that our MetroNID® solution would meet the demanding set of requirements that SureWest’s wireless operator customers demanded and welcome the opportunity to continue adding value to SureWest’s Wireless Carrier Backhaul service.”

Accedian will be speaking at the Light Reading Mobile Backhaul Live event in New York City this June 23rd. Event information: Accedian.com/events. A white paper version of this case study is available by visiting www.Accedian.com.

Spread Networks Sets New Standard for Latency NY-Chicago

Tuesday, June 22nd, 2010

Spread Networks, a privately-owned telecommunications provider has launched a dark fiber private network specifically optimized for ultra-low latency for financial industry customers who communicate between Chicago and New York trading centes.
In part, Spread Networks can offer unparalleled levels of latency performance because it has built a brand-new, direct route over the shortest possible route from New York to Chicago, 825 fiber miles long – reducing
round-trip latency to 13.33 milliseconds. Up to this point, the lowest latency on the New York-Chicago route was about 15.9 milliseconds, according to Brian Quigley, ADVA Optical Networks senior director.
Where other low-latency connections between those cities uses railroad rights of way, Spread Networks has built along alternate routes, to shave distance, and hence delay. It’s just a guess, but if you want to follow the straightest-possible route between New York and Chicago, you’d follow U.S. Highway 80. That would allow a carrier to relatively easily negotiate rights of way agreements with a few entities and obviously allows easy trenching along the medians.
“Spread Networks has established the competitive standard for trading latency between these two important
financial centers,” said David Barksdale, CEO of Spread Networks (Barksdale was Netscape’s CEO) .
Spread Networks provides customers two strands of dark fiber, which are lit using optoelectronics provided by ADVA Optical Networks. Traffic is kept at layer one to avoid the additional latency if the traffic were carried at a higher level of the protocol stack.
The route terminates at 350 East Cermak Road in Chicago Illinois (telX) and 1400 Federal Blvd in Carteret, New Jersey (Lexent Metro Connect).
As part of the service, ADVA monitors the routes, providing real-time latency reporting. Repeater huts are spaced at 120 kilometers and the route uses low-noise optical amplifiers, dispersion compensation, cut-through switches and no protocol conversion or higher-level switching as part of the effort to achieve the lowest-possible latency performance.

Telstar, Nokia Siemens Demo 100 Mbps LTE at 75 Km

Monday, June 21st, 2010

Telstra and Nokia Siemens Networks have conducted groundbreaking trials of Long Term Evolution networks in Australia, successfully achieving peak speeds of 100 Mbps download and 31 Mbps upload over a record-breaking distance of 75 kilometers in regional Victoria.

Performance of that sort helps explain why, after years of wrangling, Telstra has agree to essentially divest itself of its fixed-line network and become a wholesale buyer of capacity to support its fixed-line operations.

Commercial deployments rarely achieve the “hero” performance demonstrated in a lab or a limited field trial. But the Telstra test shows what can be done using LTE, and further illustrates what may be needed in backhaul networks when a single end user can burst up to 100 Mbps in the downstream direction.
