Abstract: Presented herein are techniques for detection and characterization of buffer occupancy of a buffer in a network device. Packets are received at a network device. The packets are stored in a buffer of the network device as they are processed by the network device. An occupancy level of the buffer is sampled at a sampling rate. Occupancy levels of the buffer over time are determined from the sampling, and traffic flow through the network device is characterized based on the occupancy levels.

Abstract: Two polygon fill algorithms are presented for filling polygons on a graphics display. The first polygon fill algorithm fills polygons that are strictly convex. The second polygon fill algorithm fills a larger class of polygons than the first polygon fill algorithm which includes polygons being concave in the x direction, and polygons having crossing lines. The first polygon fill algorithm tests the polygon for strict convexity by testing for a consistent turning direction, and by testing for once around in the y direction. The first polygon fill algorithm then stores the maximum and minimum value of the pel selected by the Bresenham algorithm for each scan line of the polygon. The fill line is drawn from the pel having the minimum value to the pel having the maximum value for each scan line of the polygon. The second polygon fill algorithm tests the polygon to ensure that it can be filled with one unique fill line for each scan line of the polygon.
