Abstract: Systems and methods for monitoring a computer network are provided. A network monitoring system generates a plurality of monitoring packets. The plurality of generated monitoring packets travel along respective paths through the computer network across a plurality of monitored links to respective destination nodes. Every monitored link in the computer network is included in at least one path. Each monitoring packet includes forwarding information which identifies each of the monitored links the monitoring packet is to traverse along its respective path. The network monitoring system tracks receipt of the generated monitoring packets by the respective destination nodes to detect faulty links.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining image search results. One of the methods includes storing data representing a collection of predetermined paths through a network of devices. One or more packets are transmitted along each of the predetermined paths, wherein each packet includes instructions for forwarding the packet along a distinct path of the predetermined paths. One or more of the transmitted packets are received. Two or more problem paths are identified using the transmitted packets and the received packets. A problem link between two network devices is determined based on a comparison of the problem paths.

Abstract: A method for searching for a digital image representing a graphical pattern generates the descriptor of an image as a 2D m×n matrix (m, n: whole numbers): resample digital image to produce normalized image of dimensions c.m×d.n (c, d: given whole numbers), process the normalized image in p processes, indexed 1-p (p: given whole number), producing p digital characteristic images (CI), each having m×n sub-images (SI), each S-I being c×d, each CI is reduced to m×n by replacing each SI by at least one representative value determined as a function of the c×d SI pixels, a selection function selects from p values, at least one value as selected value, each descriptor element (i, j), i?[l,m], j?[l,n] is allocated the processing index from which the CI is derived generating the reduced image including the selected value from the selection function applied to p pixels (i, j) of the P reduced images.
