Latest Patents
Kajiyama's latest patents include a loop-back system in a dual ring network. This innovative technique is designed to recover from failures in a ring network by transmitting information to a specified path indicated by a path ID number or time slot position. The system establishes working paths between transmission and receiving nodes while creating protection paths in the opposite direction. This allows for a loop-back from the working paths to the protection paths at the node that detects the failure.
Another significant patent is related to packet networks and methods for congestion avoidance. This invention controls packet transfer by predicting potential congestion based on an acceleration rate of packet transfers. It effectively prevents packet loss in networks by managing the transfer rate and reducing the need for buffer memory capacity at nodes. This proactive approach to congestion management enhances the efficiency of packet integrated networks.
