Abstract

See full text

Access control lists (ACLs) permit network administrators to manage network traffic flowing through a networking element to optimize network security, performance, quality of service (QoS), and the like. If a networking element has multiple ACLs directed towards different types of network optimization, each ACL may return a separate action set that identifies one or more actions the networking element should perform based on a received frame. In some cases, these action sets may conflict. To resolve the conflicts, a networking element may include resolution logic that selects one of the conflicting actions based on a predefined precedence value assigned to each action in an action set. By comparing the different precedence values, the resolution logic generates a new action set based on the actions with the highest precedence value.
