Abstract: The present disclosure is directed towards systems and methods for executing cryptographic operations across different types of processing hardware. An intermediary device may identify a cryptographic function to be performed at the device, according to a message from a client or a server. The device may identify a sequence of cryptographic operations to be executed for performing the cryptographic function. The device may determine subsets of the cryptographic operations to be executed on across different types of processing hardware. The different types of processing hardware may reside on the device. Each of the types of processing hardware may execute, responsive to the determination, the respective subset of the cryptographic operations, according to the sequence of the cryptographic operations.

Abstract: A system and method is provided for controlling multimedia data transmission to a communication device via a network. The system comprises a de-muxer configured to obtain a first multimedia data for transmission and a flow controller configured to evaluate an estimated buffer time associated with the communication device. If the estimated buffer time satisfies a first threshold condition, the flow controller updates a current transmitting state to be a pacing state. And if the estimated buffer time satisfies a second threshold condition, the flow controller updates the current transmitting state to be a bursting state. The system also comprises a muxer configured to transmit the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.

Abstract: A cache server includes a memory, and a processor to acquire segments of media data associated with a first request, with the first request being generated by a client device. The segments associated with the first request are stored in the memory. Keys for the segments associated with the first request are generated, with each segment having a respective key associated therewith that is a unique identifier for that segment.

Abstract: A cache server, a method, and a non-transitory computer-readable medium storing a set of instructions are disclosed. The apparatus comprises a memory and one or more processors configured to acquire one or more segments of media data associated with a first request, the first request being generated by one or more client devices, store the one or more segments associated with the first request, generate a key for each segment of the one or more segments associated with the first request, and generate a first set entry and a first set key for the one or more segments associated with the first request.
