Wind River has added the Sigtran (signalling transport) telecomms signalling protocol to its WindNet suite of networking protocols.

Wind River has added the Sigtran (signalling transport) telecomms signalling protocol to its WindNet suite of networking protocols.

With the addition and integration of Sigtran into the current suite of WindNet products, Wind River reckons it can offer the industry's most complete voice-over-IP (VoIP) solution, enabling the rapid development of advanced, converged telecom products such as soft switches, media gateways, wireless infrastructure systems and VoIP servers.

WindNet Sigtran enables VoIP network equipment to access the Signaling System 7 (SS7) network across an IP network, minimising the need for direct connections to the SS7 network.

Sigtran and other technologies supporting the distributed voice and data network serve as the foundation for future converged communications networks.

According to research firm Frost and Sullivan, converged voice/data equipment revenues were $1.39 billion in 2000, and are projected to reach $14 billion by 2006.

This growth in the market for converged networks is further supported by the decreasing bandwidth requirements carriers are seeing for transmitting voice messages over an IP network as the performance of speech compression technologies continue to improve.

The modular architecture of WindNet Sigtran allows developers to select needed components based on specific application requirements.

The scalability of WindNet Sigtran makes it applicable for a variety of infrastructure equipment applications within the distributed network architecture that is the foundation for VoIP services.

Examples of VoIP infrastructure equipment include, signalling gateways, trunking gateways, media gateway controllers, call agents, softswitches and VoIP servers.
