Abstract
In general, techniques are described for selectively applying and reusing filters stored in a router. In one example, a method includes receiving a network access request from a first user. The method also includes selecting a candidate rule group associated with the packet flow, wherein the candidate rule group comprises one or more currently deployed rules of an existing rule group on the computing device that are currently installed within a forwarding plane and are being applied by the forwarding plane to network traffic associated with a second user. The method also includes installing a new rule group comprising the one or more currently deployed rules of the existing rule group and one or more new rules associated with the first user and not currently installed within a forwarding plane. The method also includes applying each rule of the new rule group to network traffic associated with the first user.
