"P-Cube, the traffic management firm Cisco agreed to buy for $200m last month, is aiming to tackle the problem of spam at source by detecting and quarantining spam zombie machines.
P-Cube's IP service control platform allows service providers to identify subscribers, classify applications and offer differentiated service performance. The technology makes it easier for telcos to control and manage advanced IP services such as voice-over-IP, interactive gaming, video-on-demand, or P2P traffic. P-Cube has tweaked this technology to help fight one of the principal causes of spam."
interesting to see how this plays out
