Abstract: An apparatus and method for enhancing packet transfer in a network using duplicated copy of data packets are disclosed. Upon classifying a data packet in accordance with a set of predefined packet identifiers, the method for enhancing packet transfer, in one embodiment, generates a replicated packet which is substantially similar to the data packet in response to the result of classification of the data packet. The replicated packet is subsequently forwarded to an application component via a route of non-bearer traffic for facilitating parallel processing.

Abstract: An amplifier circuit for a cable access television line amplifier has a circuit input and a circuit output and includes a first cascode amplifier having a first input and a first output, and a second cascode amplifier having a second input and a second output where the second cascode amplifier is coupled in a push-pull arrangement with the first cascode amplifier. The amplifier circuit further includes input circuitry for coupling the circuit input to the first and second inputs and output circuitry for coupling the first and second outputs to the circuit output. The first cascode amplifier includes a first field effect transistor coupled to the first input; the second cascode amplifier includes a second field effect transistor coupled to the second input; the first cascode amplifier further includes a third field effect transistor coupled to the first output; and the second cascode amplifier further includes a fourth field effect transistor coupled to the second output.
