Latest Patents

Chow's latest patents include innovative systems and methods for restoring disrupted telecommunications networks. One of her patents outlines a comprehensive approach to restoring a disrupted telecommunications path between a source node and a destination node via at least one tandem node. This method operates in five distinct phases: notification, broadcast, path trace-out, confirmation, and cleanup. During the notification phase, the source and destination nodes are alerted to the disruption. The broadcast phase involves flooding the network with PACK messages to locate restoration paths, while the path trace-out phase conservatively reserves bandwidth along these paths. The confirmation phase builds restoration paths step-wise, ultimately restoring the disrupted connection. Finally, the cleanup phase releases all network resources that are no longer needed.

Another patent focuses on a fast distributed network restoration system for addressing traffic disruptions caused by cut links in a digital cross-connect system (DCS) network. This method employs a two-prong approach, where both ends of the cut link send out restore messages simultaneously. The end nodes are designated as a Gray Origin node and a Black Origin node, which broadcast restoration request messages to their respective neighbor nodes. Once an intermediate node receives both types of messages, it identifies a restoration path and connects the spare channels accordingly.
