Abstract
The rate at which packets are provided to a cryptographic engine of a cryptographic system is adjusted using a feedback mechanism to increase the output of the cryptographic system. Data is classified and queued on a per class/flow basis and stored in input queues prior to being processed. A class based queue scheduler is implemented to select data from the input queues to be transmitted to the cryptographic engine. The cryptographic engine operates in processing cycles. At each cycle, an amount of data is transferred from the input queues to a cryptographic engine input queue. A cryptographic accelerator in the cryptographic engine processes the data on the cryptographic engine input queue during the cycle. The output rate of the cryptographic accelerator is measured during the cycle and this value is used as feedback to determine how much data should be passed to the cryptographic engine for a subsequent cycle.
