Abstract
Performance of connection flow management between a hardware-based network interface and a software module of a network traffic management device is disclosed. A flow connection setup for a flow connection is established between a client device and a server at the network traffic management device. It is then determined if the flow connection is symmetrical or asymmetrical in nature. A flow signature entry and a transformation data entry for the flow connection is generated, by software executed by the network traffic management device, in opposing first and second symmetric or asymmetric flow directions. The flow signature entry and the transformation data entry for the first and second flow directions is sent from the software module to the network interface. The network interface stores and utilizes the flow signature entry and the transformation data entry to perform acceleration on data packets in the first and second flow directions.
