Latest Patents

Atousa holds a patent for a "Limited perimeter vector matching fault localization protocol for survivable all-optical networks." This inventive method is activated when alarming sinks are identified. Each alarming sink broadcasts its node ID and path length, allowing all nodes to compare their paths to identify an executive sink. The executive sink creates an Affected Link Vector consisting of the links in its lightpath, which is multicast within a limited perimeter. This perimeter includes all nodes within a specified neighborhood size. Each recipient returns an outcome vector corresponding to the Affected Link Vector, along with a status indicating whether the corresponding lightpath is healthy. For failed lightpaths, corresponding cells of the binary vector are set, while healthy lightpaths have their bits inverted. The vectors are ANDed by the executive sink to identify disconnections, and the process can be repeated for progressively larger limited perimeters. The affected path is restored through link restoration, allowing multiple fault localization exercises to be performed simultaneously.
