Title: Rainer Iraschko: Innovator in Optical Networking
Introduction
Rainer Iraschko is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of optical networking, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is titled "Method and system for bi-directional path switched network." This invention provides a system for detecting a failed optical path in a bi-directional path switched ring network and establishing a protection path. The system allows signals from the failed optical path to be re-routed via the protection path. Upon detecting a failure, the destination node generates a connection request message, which is transmitted to the source node through intermediate nodes. Each intermediate node reserves the necessary wavelength from the protection capacity to facilitate the re-routing of signals. The source node then prepares its switching equipment and sends an acknowledgment message back to the destination node. This process ensures that the re-routed signals can be carried effectively.
Another significant patent by Iraschko is the "Optical-ring integer linear program formulation." This method focuses on minimizing the costs associated with designing an optical network. It involves inputting channel and cost parameters, calculating band parameters, and using an integer linear program to solve a minimization objective function. This innovative approach allows for the optimization of costs in optical networks.
