P-Cube’s technology is designed to overcome the inability of current IP networks to differentiate between services like Voice-over-IP, web browsing, music downloads, video streaming or P2P traffic, making it impossible to control the quality of individual services or charge for them effectively.

Mike Volpi, SVP and general manager of Cisco’s routing technology group, said the deal reflected its on-going effort to bring service intelligence into IP data networks.

P-Cube’s Service Control system is designed to add additional intelligence and application-level control to existing IP transport networks, to enable service providers to analyze, control and meter application and content-based services.

Sunnyvale, California-based P-Cube was formed in 1999 and has 118 employees.
