Patents by Inventor Ramakumar RAJAGOPALAN

Ramakumar RAJAGOPALAN 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: 9801094
    Abstract: This disclosure relates to a system and method for dynamically managing load on network devices in a distributed manner. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network to accommodate increased data traffic is neither desirable nor practical. One way to accommodate increased data traffic is by utilizing network resources more efficiently. This disclosure provides systems and methods for efficiently utilizing network resources by dynamically configuring the network in a distributed manner based on real-time load information.
    Type: Grant

    Date of Patent: October 24, 2017
    Assignee: Cisco Technology, Inc.
    Inventors: Ramakumar Rajagopalan, Hassan Khani Sidhiq, Mohan Rangan, Aditya Prakash, Lakshman Kumar Narayanan, Sridhar Bhaskaran

  • Patent number: 8923863
    Abstract: In one embodiment, a method comprises activating a signaling reduction mode on a wireless access node for a mobile device in an idle state where the signaling reduction mode permits the mobile device to switch radio access technologies while maintaining registration with both the wireless access node and a peer wireless access node, exchanging with the peer wireless access node a first control tunnel identifier of the wireless access node and a second control tunnel identifier of the peer wireless access node, selecting at the wireless access node a second gateway to replace a first gateway, establishing a control connection with the second gateway, transmitting to the second gateway the second control tunnel identifier of the peer wireless access node so that the second gateway may establish a control connection with the peer wireless access node, and continuing the signaling reduction mode.
