Nominum Releases Navitas 3.0 to Accelerate Deployment of IP Telephony

By Susan J. Campbell, TMCnet Contributing Editor

Nominum (News - Alert), a provider of network naming and addressing solutions, has announced the release of Navitas 3.0. This IP-application Routing Directory (IPRD) is designed to uniquely accelerate the deployment of IP telephony.

Navitas 3.0 provides a platform that integrates legacy telephony numbering plans and IP routing identifiers, giving carriers an evolutionary path toward profitable business models using VoIP (Voice over IP).

The directory also enables the consolidation and simplification of routing plan management processes, while also improving telecommunication margins and optimizing the usage of profitable and reliable routes.

The decision to migrate to IP telephony has been made by many carriers as they are challenged by declining voice revenues and face increasing competition as well as industry pressures to adapt their existing business model in order to remain profitable.

These carriers also need to invest and execute very carefully as they move to IP. Significant barriers to successful migration include cost, control and complexity.
Navitas 3.0 is positioned as enabling carrier to easily transition to an IP telephony business model and extend telephony services to support a voice-enabled Web. This is all possible without having to duplicate network functionality between legacy signaling systems, such as Signaling System 7 (SS7) and IP.

"As the convergence juggernaut continues, carriers will increasingly struggle to sustain their business model and profit margins," said Brian Partridge, program manager in Yankee Group's (News - Alert) Enabling Technologies Service Provider group, in a Monday statement.
"Rather than equating VoIP and VoIP peering for settlement free services, carriers are increasingly seeking networking functions such as IP-application Routing Directories to manage and bill telephony services on IP as they see fit."

Navitas 3.0 is also positioned as providing the foundation for next-generation networks like IP Multimedia Subsystem (News - Alert) (IMS) by allowing carriers to reuse existing routing plans. The solution also helps to modernize the integration into next-generation networks through automation.

Navitas 3.0 is designed to provide a higher Quality of Service (QoS) over IP through its enhanced management and reporting functionality. It also helps carriers to avoid increased spending on Time Division Multiplexing (TDM) and SS7 technology, and facilitates the development of new IP-based applications.

"VoIP interconnects are growing around the globe and service providers require scalable address resolution as well as security and control at the interconnect borders," commented Seamus Hourihan, Vice President Marketing and Product Management, Acme Packet (News - Alert), in Monday’s statement. "Both Acme Packet and Nominum are attentive to our customers' requirements for VoIP peering and we continue to innovate and deliver features designed to build reliable, scalable and trusted VoIP interconnects."

The core technologies and features of the Navitas 3.0 include: Cascading query engine federates multiple sources of routing data; Support for parameter-based routing including Least Cost Routing applications improves telecom margins through profitable and reliable routes; and a Framework for Service Oriented Routing (SOR) for resolution of multiple routing decisions.

"As the industry transitions to an all-IP world, carriers require a robust IPRD that is switch and data source agnostic and can serve as a control point for advanced services," said Tom Tovar, chief executive officer, Nominum, in Monday’s statement. "Navitas 3.0 provides the pivotal first step toward a cost-effective migration from SS7 to IP. This product addresses the immediate needs of the VoIP and VoIP peering markets as well as future network requirements, without requiring carriers to wait for all-IP or IMS architectures."

Navitas Element Management System (EMS) is a turn-key solution that provides carriers with a single point for administration across a network of Navitas IPRD and ARM servers. It also provides enhanced data collection and reporting and enables accurate Quality of Service (QoS) measurements.

Companies throughout the globe are recognizing the benefits that VoIP can provide for not only their telecommunications, but also for their overall operation. As these benefits become more apparent, demand for the technology will continue to grow.

As more carriers are migrating towards IP telephony, they are searching for solutions that help to facilitate greater control and lower costs. With the Navitas 3.0 solution, they are in a better position to achieve their goals as they can integrate with existing systems.
These next-generation technologies have proven to deliver increased efficiencies and lower costs. Both aspects can be optimized when the organization teams with a reliable vendor that can deliver on its promises.
