Overview
Redback Networks was a United States telecommunications-equipment company focused on the infrastructure used by Internet service providers to deliver and manage broadband services. Rather than operating a consumer-facing access network, the company developed hardware and software that helped service providers authenticate subscribers, control sessions, provision services, manage traffic, and support large-scale broadband deployments. The company was founded in August 1996 by Gaurav Garg, Asher Waldfogel, and William M. Salkewicz. Its early financing included seed investment from Sequoia Capital. Redback emerged during the rapid expansion of Internet access and telecommunications infrastructure in the late 1990s, when service providers were moving from narrowband dial-up systems toward cable, DSL, and other forms of broadband access. This market created demand for specialized subscriber-management and edge-network equipment capable of handling growing customer volumes and differentiated service plans. Redback became a public company in May 1999 through an initial public offering. Its shares reportedly priced at $23 per share and rose sharply on the first day of trading, reflecting the intense investor enthusiasm surrounding networking and Internet businesses during the dot-com period. The company subsequently pursued acquisitions to broaden its technology portfolio. In November 1999, it acquired Siara Systems in an all-stock transaction reported at approximately $4.3 billion. Siara’s products were still at the prototype stage at the time of the transaction. Redback also acquired Abatis Systems in August 2000. The company’s principal product families included the Subscriber Management System, commonly known as SMS, the SmartEdge platform, and the SmartMetro line. These products addressed different elements of broadband-service delivery, including subscriber control, carrier-grade edge routing and aggregation, and metropolitan network connectivity. Their customers were primarily telecommunications carriers, cable operators, and other Internet service providers rather than individual consumers. Redback’s market value was heavily affected by the collapse of the dot-com and telecommunications investment cycle. Its share price reached a reported peak of $198 in 2000 but later fell to $0.27 in October 2002 after the technology-market bubble burst. During this broader period of industry restructuring, the company continued operating as a supplier of broadband access and service-management technology. It opened a regional headquarters in Hong Kong in October 2000, reflecting its efforts to support business in Asian and other international markets. In January 2007, Ericsson acquired Redback Networks for approximately $1.9 billion, or $25 per share. The acquisition ended Redback’s independent existence and brought its broadband-access and service-edge capabilities into Ericsson’s carrier networking portfolio. Redback Networks is therefore best understood as a former communications-technology company and acquired enterprise brand, not as an active standalone operator or consumer telecommunications brand.
History
Redback Networks was established in August 1996 by Gaurav Garg, Asher Waldfogel, and William M. Salkewicz. Sequoia Capital provided seed financing. The company entered the market as Internet access was shifting toward broadband, creating a need for equipment that could manage large numbers of subscribers and support the operational requirements of Internet service providers. Its technology centered on the service-provider edge of the network. Redback supplied systems that allowed carriers and other providers to manage subscriber sessions, apply service policies, aggregate access connections, and support broadband delivery. This placed the company in the business-to-business telecommunications-equipment sector rather than in consumer electronics or retail Internet access. In May 1999, Redback completed an initial public offering during the peak of the dot-com investment boom. Its shares were priced at $23 and reportedly increased 266 percent on their first trading day. The company then used acquisitions as a means of expanding its product and technology base. In November 1999, it acquired Siara Systems in an all-stock deal reported at approximately $4.3 billion. Siara’s products were described as being at the prototype stage when the acquisition took place. Redback acquired Abatis Systems in August 2000 as well. The company’s market capitalization was subsequently caught in the collapse of technology and telecommunications valuations. Its share price reached a reported high of $198 in 2000 before declining to $0.27 in October 2002 following the bursting of the dot-com bubble. This decline reflected the severe revaluation of networking companies during the sector downturn, although Redback continued to develop and sell infrastructure for broadband providers. Redback’s named product families included the Subscriber Management System, or SMS, SmartEdge, and SmartMetro. The SMS line was associated with subscriber and broadband-service management. SmartEdge addressed carrier-grade edge-network functions, while SmartMetro focused on metropolitan networking applications. Together, these lines positioned Redback as a supplier of platforms connecting access networks with the service-provider core and operational systems. Redback also developed an international footprint. In October 2000, it opened a regional headquarters in Hong Kong. This move reflected the importance of Asian telecommunications markets and the need to provide regional sales and support for carrier customers. Ericsson acquired Redback Networks in January 2007 for approximately $1.9 billion, or $25 per share. The transaction absorbed Redback’s technology and business into Ericsson and ended Redback’s independent corporate life. Because the company was acquired rather than continuing as a standalone brand, its historical importance lies primarily in the development of broadband subscriber-management and service-edge networking during the expansion of commercial broadband Internet access.
