In particular, techniques are described in which information is transferred across a common interface between two neighboring fine-grids. Furthermore, techniques are also described in which, during the update of a grid in regions where there exists an embedded fine-grid, the field values at co-located edges at which fine-grid solution points exist on the grid, are summed and used in an approximation of the gradient term required for the FD-TD updating stencils to perform an electromagnetic simulation.

Abstract: A multiple-access contention-free environment is disclosed for a local area network without using centralized control and without using information contained in the data. Data collisions are eliminated by buffering data from connected devices when the bus (or other common transportation media) is not available for immediate use. In one embodiment, the buffering is controlled by hubs that can accept information or hold it up for a period of time until the buffer clears. Buffer fullness can be used, if desired, as a measure as to which buffer to draw from first. When buffers are full, signals are sent to the stations to reduce their access to the network on a temporary basis.

Abstract: Systems and methods which provide a scheduled media access control (MAC) architecture are shown. Scheduled MAC architectures provided according to embodiments result in a one function-at-a-time approach, wherein stations are provided parallel process media access. A communication framework is established for communication among stations, wherein the communication framework preferably defines how to request to access, how to send data frames, and/or how to terminate a session in terms of functional intervals. The functional intervals are preferably arranged in such a manner that the fairness, throughput efficiency, contention, traffic flow management, and latency are considered. A super frame structure is preferably defined from the various functional intervals. The scheduled MAC architecture could co-exist with other MAC protocols such as those based on carrier sensor multiple access schemes.

Abstract: The present invention provides a method for supporting frame priority in a home phone line network. The method includes: detecting a limited automatic repeat request (LARQ) header in a frame with a priority tag; stripping the LARQ header and a frame check sequence (FCS) in the frame with the priority tag; recalculating the FCS for the stripped frame with the priority tag; and adding the recalculated FCS to the stripped frame with the priority tag. The method strips the LARQ header from a HPNA frame with the priority tag before it is sent to an Ethernet controller. By stripping the LARQ header, the Ethernet controller will correctly recognize the priority tag and send the frame to the appropriate priority queue. In this manner, frame priority is supported.

Abstract: A method for communicating a Physical Layer (PHY) mean square error (MSE) to an upper layer device driver includes: receiving a frame by the PHY; computing a MSE for the frame by the PHY; sending the MSE and the frame to a Media Access Control (MAC); inserting the MSE into a frame status frame (FSF) associated with the frame by the MAC; and sending the frame and the FSF to the upper layer driver software. With access to the PHY MSE, the upper layer driver software can compute the average mean square error (AMSE) and determine if a change in the payload encoding (PE), or data transmission rate, should be negotiated. In this manner, the data transmission rate can be optimized while maintaining a low error rate.
