Abstract
Bidirectional flows of a communication session in a software defined network (SDN) are efficiently managed. A smart switch comprises a digital processing unit (DPU) complex comprising one or more DPUs, and a switching complex comprising one or more network processing units (NPUs). The DPU complex is configured to disaggregate enforcement of policies of the SDN from hosts of the SDN. The switching complex is configured to perform network routing of packets in the SDN. The hosts are implemented on servers communicatively coupled to network interfaces of the SDN. The switching complex is configured to perform policy enforcement of data flows for communication sessions that are offloaded from the DPU complex to the switching complex.
