摘要： One embodiment of the invention is an architecture for improving the performance of a computer system containing a plurality of hardware input/output devices. The architecture implements an operating system configured to perform all related input/output operations within the operating system kernel. Thus, the operating system enables a first device driver that produces data to pass data directly to a second device driver that consumes data, without a context switch. One advantage of this approach is that computer system performance may be substantially increased due to a reduction in context switching.

摘要： One embodiment of the present invention is a computer system having an operating system that includes a first device driver and a second device driver, and a hardware layer that includes a first input/output device controlled by the first device driver and a second input/output device controlled by the second device driver. In response to a request, the first input/output device is configured to transmit data directly to the second input/output device, without the data first being transmitted to the first device driver or to the second device driver. One advantage of the disclosed architecture is that all related input/output operations are performed in the hardware layer such that data can be transmitted directly between input/output devices without context switching or use of software data buffers. Such an approach may substantially increase overall performance due to reductions in context switching and software overhead.

摘要： The present invention provides a method and an apparatus to facilitate the use of larger-than-Ethernet-standard frames having different sizes in a network, such as an extended local area network, where the network can include at least one network element that cannot transfer data as larger-than-Ethernet-standard frames. In one embodiment, a method for formatting data for transportation over a network comprises identifying a network element capable of using data formatted as a non-standard frame, such as a jumbo frame. Then, the method provides for determining a non-standard frame size that is useable by the network element. More generally, the technique is applicable to any LAN infrastructure comprised of devices supporting a variety of frame sizes, so that any device may discover the largest frame size that is supported to any other device within the same network.

摘要： A method of saving power in a wireless network can include determining a plurality of stations associated with an AP. The AP can create station groups using group selection logic. Notably, the group selection logic is transparent to the plurality of stations. A plurality of TIMs can then be sent, each TIM allowing only one station group access to a channel during a predetermined time interval, such as a beacon interval. In another method, a station can determine its sleep duration based on at least one of first information from the TIM to generate random sleep duration, second information regarding previous operation of the station, and third information regarding a status of the station. The first, second, and third information can include the number of stations associated with the AP and having buffered data based on the TIM, historical collisions, and power status.

摘要： A buffer ring is utilized to track and control the distribution of information. Index variables that refer to storage locations or slots in the buffer ring are utilized to track the receipt and distribution of information. The variables initially point to the same slot. As information is received a status indicator associated the slot is checked and if the location is free either the product information elements or addresses of where the product information are entered in the slots. They are tracked by a producer variable that is incremented to indicate the next available slot. Slots between the consumer variable and the producer variable define a segment of the buffer associated with a particular thread. The information is forwarded to a thread based upon the variables. As product information elements are forwarded control of the buffer ring is obtained and the variables determine a buffer segment that is forwarded.

The communications device is configured to increase the amount of decryption performed using a hardware-based process as compared to a software-based process by reprogramming the hardware to store a shared security key corresponding to a frame received from a source, allowing the hardware-based process to decrypt subsequent frames from that source.
