Sivasankaran Nagarajan 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: 11652664
    Abstract: Examples disclosed herein relate to managing a second ring link failure in a multi-ring Ethernet network. In an example, an inter-connection network node in a multi-ring Ethernet network comprising a major ring and a sub-ring may propagate a signal failure (SF) event, received in response to a second ring link failure in the major ring, to one or more nodes in the sub-ring. In response to receiving the SF event, a Ring Protection Link (RPL) on the sub-ring may be unlocked to allow network traffic through the RPL and avoid loop formation on the multi-ring Ethernet network. The sub-ring may be moved to the ring protection switching state, including performing a filtering database (FDB) flush at every node on the multi-ring Ethernet network whereby all MAC addresses and related port associations for traffic forwarding are cleared from the FDB.

  • Publication number: 20230070609
    Abstract: Methods for provisioning and managing Internet-of-Things (IoT) devices over a network using device based tunneled nodes are provided. In one aspect, a method includes receiving, by a first network device in a network, data originated from an Internet-of-Things (IoT) device; identifying a device type of the IoT device by analyzing data packets of the received data; obtaining, by the first network device, a device profile for the IoT device, wherein the device profile is used for provisioning the IoT device to access the network; and provisioning the IoT device using the device profile, wherein the provisioning includes at least one of (1) identifying a tunneling attribute in the device profile; and (2) identifying a constrained application protocol (CoAP) parameter in the device profile, wherein the CoAP parameter is used to zero touch provision one or more device attributes of the IoT device. Systems and machine-readable media are also provided.

  • Patent number: 10616220
    Abstract: A method, executable by a switch to automatically onboard end devices connected thereto, comprises detecting that an end device has connected to the switch, and determining a device identity of the connected end device. The determined device identity is used to obtain a configuration template profile associated with the connected end device. The switch is configured using the obtained configuration template profile.
