Abstract: A system and method for enabling energy efficient Ethernet networks with time-sensitive protocols. Time-stamped packets generated by a time-sensitive protocol rely on fixed latency in a transit time through a transmission subsystem. An energy efficiency control policy in a network device governs a transmission of time-stamped packets in accordance with energy efficiency initiatives controlled by the energy efficiency control policy. In one embodiment, time-stamped packets can be dropped or modified to account for transitions by the transmission subsystem into an energy saving state. In another embodiment, transitions by the transmission subsystem into or out of an energy saving state can be impacted by the existence of time-stamped packets scheduled for transmission.

Abstract: A method and system for network offloading includes receiving a packet at a communication interface of a wireless access point and processing the packet at a flow acceleration processor prior to processing the packet at a host processor. The flow acceleration processor may process the packet for header checking or security processing. The flow acceleration processor may provide the packet to a security coprocessor for security processing. The flow acceleration processor may generate a result code indicating whether the processing at the flow acceleration processor was successful. If the processing was unsuccessful, the packet is provided to the host processor for exception processing.
