Methods, systems and computer program products for packet ordering for parallel packet transform processing

Packets are processed while maintaining a sequence of the packets. Packets are received and a sequence identifier assigned to the packets. The sequence identifier specifies a serial order associated with the packet. The packets are provided to a plurality of parallel packet transform processors and the packets are processed utilizing the packet transform processors. The processed packets are ordered based on the sequence identifier of the packets. The packets may be evaluated to classify the packets so as to identify related packets. A sequence identifier is assigned to the packets such that the sequence identifier identifies an ordering of the related packets. The processed packets are ordered based on the classification of the packets and the sequence identifier of the packets. Parallel packet transform processing may be particularly well suite to parallel cryptographic processing.
