NetNumber and NetAxis Tackle VoIP Signaling and Data Traffic QoS with Combined Offering

The complexity of today’s real-time communications networks is part of their beauty, enabling a host of rich features and solutions that are easily customizable in terms of scalability and usability. Ensuring quality of service (QoS) on these networks has always been a challenge though, and many service providers have attempted to tackle this granularly, through complicated solutions deployed at the OSS/BSS layer.


These types of solutions present issues, however, particularly when it comes to meeting the requirements of VoIP interconnects and the signaling control layer. Now that voice and data traffic are running pretty much transparently over the same networks, shouldn’t QoS be equally transparent?

NetNumber, a specialist in signaling control solutions and NetAxis Solutions, a service consultant specializing in carrier-grade VoIP and telecom solutions, have joined forces to tackle this problem. The companies are taking a broad approach to QoS by integrating real-time QoS into centralized routing control. This integrates QoS between the data network and signaling control layer, meeting the needs of VoIP interconnects and enabling service providers to offer high levels of QoS universally over their networks.

The new joint solution uses the TITAN centralized signaling and routing control (CSCR) platform from NetNumber, while real-time QoS data is delivered and provisioned via the NEMO network monitor system from NetAxis. Working together, IP traffic of all types may be adjusted dynamically for high QoS levels based on all the activity in the underlying data network.

“Service providers have struggled to address QoS issues in routing real-time services as the next generation of networks are built out,” said Manuel Basilavecchia, director of sales and marketing for NetAxis Solutions. “This is true of both voice and video sessions handled within the network of a carrier or by the interconnections of traffic between carriers.”

Basilavecchia believes this has made service providers reluctant to embrace IP-based interconnections for voice, with some countries still using circuit-switched networks for voice to get around these issues. The goal of the joint offering is to provide a central workaround offering a comprehensive view of network traffic and QoS issues.

“Carriers are looking for solutions that support next-generation networks and the delivery of new services onto a common core platform, while reducing OPEX and the myriad of problems associated with hyper-complexity in the OSS/BSS layer,” added Matt Rosenberg, vice president, NetNumber global sales, solution design and product management. “Through working with NetAxis Solutions, we can provide carriers with a whole new set of benchmark criteria that can be used real-time in making a dynamic policy decision about routing. The end result is the further simplification of how carriers integrate the signaling control and data network layers to leverage real-time QoS data within their network traffic.”
