Sonus Networks (News - Alert), a dealer in IP networking, claimed that its NBS5200 and NBS9000 products have been awarded Miercom Performance Verified Certification by Miercom Labs, an independent product test center.

The company added that the certification proved that Sonus's Network Border Switches delivers extraordinary performance even under the most adverse of conditions where other products often exhibit significant performance breakdown.   

Based on the Sonus GSX (News - Alert) Open Services Platform, the Sonus NBS9000 allows operators to satisfy all their security, session border controller and media services requirements within an integrated, easily managed system. The NBS9000 operates even in a hybrid TDM-IP environment or in pure IP applications. The NBS9000 and NBS5200 is a proven solution that integrates security, call control, Quality of Service, advanced media services and switching all within a scalable platform. 

The Sonus NBS9000 and NBS5200 provide a robust suite of security features for both signaling and media. Encryption is available as either TLS or IPSec for signaling and Secure RTP for media. Other security features include traffic policing; DoS and DDoS attack detection and blocking, and rogue RTP protection.

Built on the ConnexIP platform, the NBS5200 employs the latest generation of network processors, computing processors and digital signal processors (DSPs) to deliver the highest performance density session border controller on the market combined with integrated transcoding, media interworking and native support for IPv6 addressing. 

The company claimed that its NBS5200 is the session border controller with the greatest session density and throughput and that it can also withstand severe denial of service attacks while allowing legitimate traffic to pass through and continue to process calls successfully. 

Miercom testing evaluated the ability of Sonus' NBS9000 and NBS5200 to meet or exceed both current and future market demands with evolving market requirements in mind. Miercom tested the NBS5200 and NBS9000 under a variety of strenuous conditions including Denial of Service (DoS) attacks and the high-volume spikes that can follow a power outage.  

"We were impressed with the scalability and capacity of the NBS5200, and verified that it handily exceeded the capacity of other market-leading products," said Rob Smithers, CEO of Miercom, in a release. "With regard to the total number of endpoints successfully registered, maximum number of simultaneous calls processed and performance under overload conditions, the NBS5200 proved it has the processing horsepower to meet both present and future carrier-class demands."
