Patents by Inventor Manohar Murthy

Manohar Murthy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Communication apparatus and methods
    Patent number: 6545982
    Abstract: A multi-port packet-based bridge is described in which packet transmissions on particular ports or between ports may be monitored on another, monitoring port. Efficient operation is realized by using a multi-processor environment and data structures that allow a packet received on one port to be transmitted to multiple ports without being “copied” multiple times. By using a Supervisory Access Terminal, it is possible to specify various circumstances under which a packet will be sent to the monitoring port. These circumstances include monitoring of all packets incoming to a selected port (or ports), all packets forwarded to a selected port (or ports), and packets generated internally and sent to a selected port (or ports). In addition, all packets forwarded from one selected port to another selected port may be monitored.
    Type: Grant

In addition, all packets forwarded from one selected port to another selected port may be monitored. Port monitoring is supported by particular data structures that promote efficient dispatching of packets and by a Bridging Cache that retains the results of recent dispatch calculations.
