Patents by Inventor Suvendu Mozumdar

Suvendu Mozumdar 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).

  • Patent number: 11563773
    Abstract: A method for software-based emulation of media access control security (MACsec) includes generating, using a software-based emulated MACsec packet generator, a plurality of emulated MACsec packets, each of the emulated MACsec packets including a MACsec header having a packet number field value that remains fixed across the emulated MACsec packets. The method further includes configuring a device under test to accept plural MACsec packets with the same MACsec packet number field value. The method further includes transmitting the emulated MACsec packets to the device under test (DUT). The method further includes determining whether the DUT responds correctly to the emulated MACsec packets given a replay protection configuration of the DUT. The method further includes generating test output based on a result of the determination.

  • Patent number: 10868730
    Abstract: Methods, systems, and computer readable media for testing network elements of an in-band telemetry (INT)-capable network are disclosed. One exemplary method includes generating, by a network test tool device, at least one INT test system data packet that includes emulated INT metadata that represents telemetry parameters corresponding to a plurality of emulated network devices. The method also includes sending the at least one INT test system data packet to an INT sink device and generating, by the INT sink device, an INT telemetry report derived from the INT metadata extracted from the at least one INT test system data packet. The method also includes forwarding the generated INT telemetry report to a software defined network (SDN) controller entity.
