BEAVERTON, Ore. and ALAMEDA, Calif.--December 1, 2003--The Open Source Development Labs (OSDL), a global consortium of customers and leading technology companies dedicated to accelerating the adoption of Linux, today announced that Wind River Systems [Nasdaq: WIND], the worldwide market leader in embedded software and services, has joined OSDL and will participate in the Lab's Carrier Grade Linux (CGL) Working Group to advance support for its customers in the telecom and networking markets.

"Many of our network infrastructure customers use Wind River's VxWorks® operating system along with Linux," said Tony Tryba, vice president and general manager of market divisions for Wind River. "Wind River is committed to working with OSDL so that we can help influence the development of the Carrier Grade Linux specification and accelerate its adoption in the telecommunications industry."

Wind River's VxWorks operating system has traditionally had a very strong presence in the data plane functions of sophisticated telecom and service provider equipment. At the same time, UNIX® has often been used in the control and management functions for these systems. Recently, Wind River has seen many of its telecom equipment customers begin migrating from a world of fragmented UNIX offerings to Linux influenced by the CGL specification.

"Embedded is one of the fastest-growing and most vibrant markets for Linux," said Stuart Cohen, CEO of OSDL. "We believe that Wind River's expertise and leadership in embedded systems can add significant value to our Carrier Grade Linux Working Group. As Linux becomes more widely deployed in the telecom market, Wind River's support and contributions will be important in accelerating customer adoption of CGL."
