Kaushik Kumar RAM 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).

  • Hardware clamping of the transmission control protocol (TCP) maximum segment size (MSS) parameter in a scalable and programmable network device
    Patent number: 11997183
    Abstract: A network device includes multiple interconnected network chips where the packet processing functionality is distributed between ingress and egress pipelines. TCP MSS clamping can be implemented in the egress pipeline. Processing in the egress pipeline can identify the presence of a TCP MSS value in the packet. The egress pipeline can compare the packet TCP MSS value with a user configured TCP MSS value. The egress pipeline can replace the packet TCP MSS value with the user configured TCP MSS value if the former is greater than the latter, and recompute a checksum. The packet with the replaced TCP MSS value and replaced checksum is then forwarded from the switch toward its eventual destination.

  • Packet Forwarding Between Hybrid Tunnel Endpoints
    Publication number: 20220294665
    Abstract: In a virtual extensible local area network (VxLAN) that includes a deployment of aggregation VxLAN tunnel endpoints (VTEPs) and access point (AP) VTEPs, packet processing by the aggregation VTEPs includes distinguishing between Type 1 VTEPs and Type 2 VTEPs. When the source of an ingress packet and the next hop destination are both Type 1 VTEPs, the ingress packet is dropped.
