CEO John Chambers is expected Tuesday to announce ANS as the ninth of Cisco's "advanced technologies." Advanced technologies, part of a category that includes wireless LAN products that Cisco says fit into its long-term technology vision, have the potential to grow to $1 billion in revenue for Cisco over the next five to seven years. The other eight advanced technology areas are digital video, enterprise IP communications, home networking, hosted small-business solutions, optical networking, security, storage area networking and wireless technologies.
