Abstract
Techniques are disclosed for managing states at a networking device configured to track connections or bidirectional flows of a communication session in a software defined network (SDN). The networking device has an active processing engine and a passive processing engine. The connection record for an idle connection is maintained in the connection table stored at the passive processing engine, thereby allowing the passive processing engine to maintain connection state information for the idle connection and avoid storing connection state information for the idle connection at the active processing engine.
