Here’s Why Cisco Was Ordered To Pay $1.9B To Centripetal Networks For Patent Infringement

Centripetal Networks sued Cisco on claims the networking giant incorporated its network protection technology into its network switches and routers and the monitoring offerings that analyze their data.

Rule Swap

Centripetal Networks obtained a patent in December 2015 for a method of swapping policy rules on devices while they were actively directing network traffic.

The ever-evolving threat landscape requires frequent updates of the network traffic rules embedded in switches and routers. The patented technology can do that without having to bring down network operations.

Cisco implemented that same technology in its Catalyst 9000 series switches, as well as the ASR 1000 and ISR Router 1000 and 4000 routers, enabled by Cisco’s Digital Network Architecture—the management structure that allows the system to use threat intelligence, the judge found.

The technology is also contained in some other Cisco appliances powered by Firepower Management Center.

Cisco’s Digital Network Architecture (DNA Center) is the management structure allowing those systems to convert threat intelligence into rules that Cisco’s switches and routers implement to improve security.
