Abstract

A stateful network packet processing system includes first and second stateful stages and a distribution mechanism. The first stateful stage includes a first state table and a first FSM table. The second stateful stage includes a second state table and a second FSM table. The distribution mechanism defines when a flow should be processed by either the first stateful stage or the second stateful stage or by a combination of the first stateful stage and the second stateful stage. At least one of the first or second FSM tables is extended with states and transitions that support the distribution mechanism.
