Integrated circuit that processes communication packets with scheduler circuitry that executes scheduling algorithms based on cached scheduling parameters

An integrated circuit processes a communication packet and comprises a core processor and scheduling circuitry. The core processor executes a software application that directs the core processor to process the communication packet. The scheduling circuitry retrieves first scheduling parameters cached in a context buffer for the packet and executes a first algorithm based on the first scheduling parameters to schedule subsequent transmission of the communication packet.
