Wind River Expands Support For Voice-Over-IP Networks

VON CONFERENCE, SEATTLE, Wash., April 8, 2002 - Wind River Systems, Inc. (Nasdaq:WIND), a leading provider of software and services for connected devices, today announced the addition of Signaling Transport (Sigtran), a telecom signaling protocol, to its WindNet suite of networking protocols. With the addition and integration of Sigtran into the current suite of WindNet products, Wind River is able to offer the industrys most complete voice-over-IP (VoIP) solution, enabling the rapid development of advanced, converged telecom products such as softswitches, 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, minimizing the need for direct connections to the SS7 network.

As telecommunication carriers move to converged networks, our product offerings have grown to include the components necessary to develop, maintain and expand changing network infrastructure equipment, said Dave Fraser, group vice president and general manager of Wind Rivers Networks Business Unit. Adding WindNet Sigtran to our line of line of signaling, switching, routing, security and network management protocols, and integrating it with our operating systems and development tools gives telecom equipment manufacturers everything they need to develop and deliver carrier class network products to the market quickly, efficiently and affordably.

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 $1.39B in 2000, and are projected to reach $14B 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, Signaling Gateways, Trunking Gateways, Media Gateway Controllers, Call Agents, Softswitches, and VoIP Servers.

WindNet Sigtran is integrated with a variety of complementary WindNet protocols such as SS7, ISDN, SIP, Megaco and MGCP. In addition, these WindNet protocols are closely coupled with development tools found in Wind Rivers Tornado integrated development environment, the VxWorks and VxWorks AE real-time operating systems, and the recently released BSD/OS 4.3 operating system. This complete system-level integration offers equipment manufacturers faster time to market avoiding unnecessary evaluation, development, and procurement time.
