Aberdeen Group Awards Redback Networks for Best Practices in International Logistics Distinction Recognizes Redback’s Use of Technology and Partnership to Improve Performance

SAN JOSE, Calif., February 21, 2006 – Redback Networks Inc. (NASDAQ: RBAK), a leading provider of next-generation broadband networking systems, today announced that Aberdeen Group has selected Redback as Best Practice Winner in the Outsourcing International Logistics category.

“We are pleased that the Aberdeen Group has recognized Redback’s excellence for best practices,” said Ebrahim Abassi, Redback’s senior vice president of operations, information technology and customer service. “Greater automation, improved technologies, enhanced visibility and key relationships with strategic partners have been instrumental in Redback’s success. As part of our leveraged business model, Redback’s strategic utilization of external experts demonstrates the value of a smart corporate outsourcing strategy to reduce costs while maintaining high service level agreements for customers.”

Aberdeen’s January 2006 report entitled, “Best Practices in International Logistics,” selected eight companies, including Redback, that demonstrate excellence in transforming their international logistics operations and driving multi-million dollar savings in inventory, transportation, and logistics. By partnering with solution provider D.W. Morgan, Redback realized a 30% savings attributed to the outsourcing of its logistics network to a single logistics provider with high-quality service and inventory visibility technology.

"As low-cost country sourcing soars in popularity, companies are realizing they must transform their under-automated international logistics processes to maintain cost and customer service advantages," says Beth Enslow, Aberdeen vice president of enterprise research and report author. "Best practice winners have driven multi-million dollar improvements in their businesses through the innovative use of technology and logistics partners. Instrumental to their success is their skill and obsession with gaining and maintaining organizational buy-in for their initiatives."
