Abstract
A method and system for processing network traffic is disclosed. The method includes receiving one or more service policies from a control plane service. For each of service policies, a value pattern is generated using at least one of a source group data item and a destination group data item, and a pattern mask is generated on subset of bit locations in the value pattern. The method includes updating a lookup table to incorporate each of the one or more service policies that entails allocating memory for consolidating a new entry in a portion of the lookup table designated for control plane policies. The new entry includes a binding relating the value pattern and the pattern mask to a lookup table result, and the lookup table result specifies a traffic flow instruction and a priority level included in a service policy of the one or more service policies.
