Latest Patents

One of Barry's latest patents is titled "Synchronization of asynchronous networks using media access control (MAC) layer synchronization symbols." This patent describes a method and structure for distributing and utilizing synchronization within an asynchronous network. The synchronization is achieved through a synchronization symbol that is periodically inserted into the MAC layer data stream, ensuring its priority over other symbols. This method allows for the insertion of synchronization symbols even in the middle of ongoing data frames. Additionally, Barry presents a method for distributing synchronization symbols throughout the network and switching to a new synchronization path if the original path is lost. This innovation also includes generating an error correction signal to assist in frequency locking devices to received synchronization symbols.

Another significant patent is the "Dynamically allocated ring protection and restoration technique." This patent outlines a network design featuring two rings, one transmitting data clockwise and the other counterclockwise. During normal operations, data flows along the ring that provides the minimum number of hops to the destination node. The nodes in the network periodically test the bit error rate of the links to detect faults. Upon detection, a broadcast signal is sent to reconfigure the routing table, optimizing traffic flow to the destination node. This patent emphasizes the differentiation between protected and unprotected traffic, ensuring that critical data is prioritized during link failures.
