Harikrishnan Pillai 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: 11996949
    Abstract: Presented herein are techniques to conserve power by network devices in a software define wide area network (SDWAN). A method includes monitoring operations of a software defined wide area network including a network device in the software defined wide area network, based on results of the monitoring, generating a usage model for the network device, determining, based on the usage model, an interface selection scheme for the network device, and causing the network device to execute the interface selection scheme.
    Type: Grant
    Filed: July 28, 2022
    Date of Patent: May 28, 2024
    Assignee: CISCO TECHNOLOGY, INC.

  • Publication number: 20240015110
    Abstract: Intelligent distribution of packet flows may be provided. Compute resource data may be received. Next, packets may be classified into flows that may be persistently mapped to compute resources for a lifetime of the flows. Based on the compute resource data, the flows may then be allocated to the compute resources.

  • Patent number: 11722525
    Abstract: Techniques and mechanisms for IPsec processing of IPsec packets for routing platforms where IPsec is just one or more features in the middle of data path features on the packet processing path and hence, the typical, simple inline IPsec scheme does not work well for such platforms. The techniques include using a hardware look-up table for packet classification and inbound security association (SA) lookup in one pass with IP 5-tuple plus SPI as a lookup key at hardware table. The techniques provide an entry match action format and mechanism for deriving inbound SA dram addresses that may be used by a hardware (HW)/firmware (FW) crypto/IPsec engine to process inbound packet traffic. A software SA look-up table is also provided to overcome hardware look-up table resource limitations and support more IPsec session scaling than the physical hardware look-up table can handle. Additional techniques are described.
