    public class DataPump
extends MACActorBase
    This actor works in the Transmission block in IEEE 802.11 Mac. For every TxRequest from the Protocol_Control block, this actor sends a PhyTxStart request to the physical layer. Upon receiving the PhyTxStart confirmation, it sends data to the physical layer. After the data has been sent, it sends PhyTxEnd request to the physical layer and sends TxConfirm to the source of the original TxRequest after receiving PhyTxEnd confirmation from the physical layer.

    Both TxCoordination and RxCoordination in the Protocol_Control can send TxRequest and require TxConfirm. This actor uses a pair of input and output ports to tell the source of the TxRequest and the destination of the TxConfirm.

    • Constructor Detail

      • DataPump

        public DataPump​(CompositeEntity container,
                java.lang.String name)
         throws IllegalActionException,
                NameDuplicationException
        Construct an actor with the specified name and container. The container argument must not be null, or a NullPointerException will be thrown. If the name argument is null, then the name is set to the empty string. This constructor write-synchronizes on the workspace.
        Parameters:
        container - The container.
        name - The name of the actor.
        Throws:
        IllegalActionException - If the container is incompatible with this actor.
        NameDuplicationException - If the name coincides with an actor already in the container.
