Abstract
A method of forcefully terminating a flow includes identifying, by a hardware accelerator, a flow entry in a flow table corresponding to a flow determined to satisfy predefined criteria for flow termination and transmitting, by the hardware accelerator, a flow termination request to a software-based reset packet generator. The flow termination request includes flow match characteristics included in the flow entry of the flow table. The method further includes generating, at the software-based reset packet generator, a first transport control protocol (TCP) reset packet with header information matching the flow match characteristics and transmitting the first TCP reset packet to the hardware accelerator. The method still further provides for transforming the first TCP reset packet, at the hardware accelerator, according to a first transformation defined in the flow entry. The transformed TCP reset packet is transmitted to the destination device and the flow entry is deleted from the flow table.
