    摘要： An alternate checksum option for transmitting TCP frame data is used that does not require computing a TCP checksum. Instead, an integrity check value is computed and placed in the ESP authentication portion near the end of the frame. Transmission of a portion of the TCP frame data may begin before all of the TCP frame data is received by a TCP checksum offload device because the integrity check value is inserted at the end of the frame. Furthermore, the integrity check value is computed using a static key or a dynamic key may be computed to cover a greater portion of the frame compared with ESP authentication specified by the IPsec standard.

    摘要： A method for autonomously and dynamically optimizing transmission power of an endpoint in a wireless network includes the step of monitoring a received signal strength, a received signal quality and a transmission error rate of a signal transmitted between an access point in the wireless network and the endpoint at a given transmission power and transmission speed. The method also includes the steps of reducing the transmission power when the received signal strength, the received signal quality and the transmission error rate are at respectively acceptable operating levels and then monitoring the transmission error rate of the signal transmitted at the reduced transmission power level. The method further includes the step of adjusting one of the transmission power or the transmission speed based on whether the transmission error rate of the signal transmitted at the reduced transmission power is still at its respective acceptable operating level.

    摘要： Described are data structures, and methodology for forming same, for network protocol processing. A method for creating data structures for firewalling and network address translating is described. A method for creating data structures for physical layer addressing is described. A method for security protocol support using a data structure is described. A method for creating at least one data structure sized responsive to whether a firewall is activated is described. A data structure for routing packets is described. A method of forming hashing table chains is described. Additionally, method and apparatus for tracking packet states is described. More particularly, Transmission Control Protocol (“TCP”) tracking of states for packets is described. In an embodiment, a division between software states and hardware states is made as a packet is processed by both software and hardware. Additionally, method and apparatus for network protocol processing are described. For example, a packet for network address translation having a media access control header is obtained, from which information, including the-media access control header, is obtained. The information is parsed into one or more data structures. It is determined whether a network processing unit is in a first round processing mode, or a second round pass-through mode.
