Patent number: 9609501Abstract: A network device may be configured to provide a gateway between a remote host and a mobile node using multiple interconnection protocols. The network device may include database circuitry configured to query a database for a first or second address of a mobile node using a domain name of the mobile node. The addresses may be associated with different interconnection protocols. The network device may include communication interface circuitry configured to receive a request from a remote host to communicate with the mobile node. The request may include the domain name. The interface circuitry may also be configured to transmit a message indicating the request using the first address, and transmit the second address to the remote host so that the remote host can communicate with the mobile node using the second address. The message may include a command to establish a data bearer through the second address.Type: GrantFiled: November 14, 2014Date of Patent: March 28, 2017Assignee: Cisco Technology, Inc.Inventors: Kiritkumar B.

Patent number: 8891552Abstract: In one implementation, a method for managing access to mobile endpoints leverages the always-on nature of a first internet layer protocol to expand the reach of a second internet layer protocol. A network device receives a request originating from a remote host. The request includes a domain name of a mobile endpoint. The network device queries a database using the domain name for a first address of the mobile endpoint as designated according to the first internet layer protocol. The network device transmits a wake up message to the mobile endpoint using the first address. A data bearer for communication with the second internet layer protocol is established based on the wake up message, and a second address is assigned to the mobile endpoint. The second address is forwarded to the remote host, allowing communication between the remote host and the mobile endpoint.Type: GrantFiled: November 8, 2011Date of Patent: November 18, 2014Assignee: Cisco Technology, Inc.Inventors: Kiritkumar B.

Patent number: 8024479Abstract: A method for distributing information in a network environment is provided that includes receiving a communication flow and executing a routing decision for the communication flow that directs the communication flow to a selected one of a plurality of servers. The routing decision is based on a selected one or more user-specified parameters and on one or more data segments that reflect feedback associated with one or more of the servers. The feedback indicates one or more conditions associated with one or more of the servers.Type: GrantFiled: April 16, 2007Date of Patent: September 20, 2011Assignee: Cisco Technology, Inc.Inventors: Amitava Das, Viren K.

Patent number: 7920519Abstract: Facilitating node mobility includes facilitating a communication session for a mobile node communicated along a first communication path. A first anchor point manages context information for the communication session, where the context information comprises information for supporting the communication session. A command to transfer the context information to a second anchor point is received from a home agent. The second anchor point is operable to facilitate communication of the communication session along a second communication path. The context information is transferred in response to the command.Type: GrantFiled: April 13, 2005Date of Patent: April 5, 2011Assignee: Cisco Technology, Inc.Inventors: Anand K. Oswal, Viren K. Malaviya, John G. Waclawsky, David P. Lindert, Jayaraman R. Iyer

Patent number: 7536187Abstract: Supporting communication sessions at a mobile node includes determining at a mobile node an address for one or more interior network elements of a network system. A interior network element is distinct from an edge network element of the network system, and is operable to establish a communication session. An address for an interior network element is inserted into packets. The packets are sent from the mobile node to the interior network element to communicate directly with the interior network element. The communication session is established using the interior network element.Type: GrantFiled: August 23, 2005Date of Patent: May 19, 2009Assignee: Cisco Technology, Inc.Inventors: Anand K.
