AuBeta Networks Selects Redback's SmartEdge to Meet Demand for Secure Broadband Business Services; SmartEdge Service Gateway Enables Advanced Communication Services for Growing Base of Business Customers.

SAN JOSE, Calif. -- Redback Networks Inc. (NASDAQ:RBAK), a leading provider of next-generation broadband networking systems, today announced that AuBeta Networks, a Seattle, Washington-based Wide Area Network Service Provider, has selected the SmartEdge(R) Service Gateway to serve as the basis for their nationwide broadband network upgrade to better serve business users. AuBeta Networks, in conjunction with its partners, offers the largest Layer 2 DSL footprint in the United States.

AuBeta Networks supports over 14,000 central offices providing reliable, secure high-bandwidth communications across the United States. Leveraging the SmartEdge platform, AuBeta is migrating its legacy network to a platform that will deliver more flexible access services such as business-class DSL. In addition, AuBeta selected Redback's SmartEdge platform to accommodate increased network traffic and to optimize converged solution offerings such Voice over IP (VoIP) telephony and videoconferencing.

"We deployed the SmartEdge Service Gateway because we found it to be the only system that can support our dramatic national growth and network feature requirements on one platform," said Norm Hernandez, president and CEO of AuBeta Networks. "Leveraging Redback's technology, we can offer secure high-bandwidth services to our customers who need a reliable network to better run their businesses."

Redback's SmartEdge Service Gateway will be utilized to provide secure connectivity and enable next-generation IP-based network services to AuBeta's expanding base of business customers. SmartEdge allows AuBeta to offer tiered bandwidth and advanced Quality of Service (QoS) to reduce costs and generate additional revenue streams.

"By consolidating multiple functions onto one platform, the SmartEdge is able to offer a single service control point simplifying network operations and reducing operational costs for service providers such as AuBeta," said John Spiliotis, vice president of sales and operations for the Americas at Redback Networks. "This allows AuBeta to focus on meeting evolving customer needs and offer new and advanced broadband service solutions."
