Publication number: 20130179538Abstract: Techniques are described for reporting and monitoring network devices using microblog messaging. Embodiments monitor network traffic traversing a network device and performance metrics of the network device to detect occurrences of network and performance events. In response to detecting an occurrence of an event, a microblog message is generated. The microblog message contains at least a description of the occurrence. The microblog message is transmitted to a microblog service, which in turn forwards the message to subscribers. The microblog message may then be analyzed by the subscribers to determine operational attributes of the network device.Type: ApplicationFiled: January 10, 2012Publication date: July 11, 2013Inventors: Debojyoti DUTTA, Arun Kumar GOEL, Ganesh RAJAN, Sivakumar NARAYANAN, Gopal K.

Patent number: 8170552Abstract: Methods and apparatus for performing optimizations for a mobile network device such as a Mobile Node or Mobile Router supporting multiple links to a Home Agent (or Correspondent Node in a Mobile IPv6 environment) are disclosed. During the registration process, link characteristics are transmitted in the registration request. From the link characteristics, it is possible to determine whether the mobile network device has roamed from a high to a low bandwidth link, or vice versa. A first set of optimizations may be performed when the mobile network device has roamed from a high to a low bandwidth link, while a second set of optimizations may be performed when the mobile network device has roamed from a low to a high bandwidth link. Some optimizations may be performed during the establishment of a TCP session, while others may be performed during or upon completion of the Mobile IP registration process.Type: GrantFiled: September 27, 2010Date of Patent: May 1, 2012Assignee: Cisco Technology, Inc.Inventors: Alpesh S.

Patent number: 7599328Abstract: A data communication system is provided that allows for the efficient management of data communication sessions requested from a plurality of packet data servicing nodes organized in a cluster, each member of the cluster managing a cluster session table which contains data identifying mobile units and packet data servicing nodes which are servicing data sessions with the mobile unit. As a mobile unit moves from one portion of the system to another, a network element will request a data session from a packet data servicing node, the packet data servicing node is then able to access the cluster session table to determine if the data session is already being served by another member of the cluster. If the data session is already in existence, the base station controller will be directed to request a data session from the packet data servicing node which is already servicing that session.Type: GrantFiled: December 27, 2005Date of Patent: October 6, 2009Assignee: Cisco Technology, Inc.Inventors: Cheng-Lee Nee, Gopal K.

Patent number: 7512088Abstract: Routing data packets to a mobile node includes registering a mobile node with a home agent associated with the mobile node. The home agent establishes that the mobile node has moved from a first network to a second network, and determines a foreign access router of the second network, where the mobile node communicates through the foreign access router. A mobility binding table is updated with a binding entry associated with the foreign access router. Data packets destined for the mobile node are forwarded to the mobile node in accordance with the updated mobility binding table.Type: GrantFiled: July 12, 2002Date of Patent: March 31, 2009Assignee: Cisco Technology, Inc.Inventor: Gopal K.

Patent number: 7324492Abstract: Methods and apparatus for enabling a Mobile Node supporting mobile IP to roam without an assigned IP address and receive lookups indicating that a Corresponding Node wants to send information to the Mobile Node are disclosed. A name lookup may be sent from a Corresponding Node to a Home Agent that has previously registered the Mobile Node. The name lookup may be sent through an intermediate device, including a Domain Name Server, such that the intermediate device contacts the Home Agent. During the name lookup process, an IP address is allocated to the Mobile Node and a data path is established between the Home Agent and the Mobile Node via a Foreign Agent. When the lookup is completed successfully, the Home Agent sends the IP address allocated to the Mobile Node in the name lookup process to the device requesting the lookup. The IP address of the Mobile Node may then be used by the Corresponding Node to “push” information to the Mobile Node.Type: GrantFiled: November 7, 2005Date of Patent: January 29, 2008Assignee: Cisco Technology, Inc.Inventors: Kent K.

Patent number: 7301922Abstract: A system, a method, and software for communicating packet data are disclosed. A call is communicated from a mobile device through a first base station controller and a first packet data serving node. The call is transferred from the first base station controller to a second base station controller in communication with a second packet data serving node. The call is then communicated through a tunnel established between the first packet data serving node and the second packet data serving node.Type: GrantFiled: September 17, 2001Date of Patent: November 27, 2007Assignee: Cisco Technology, Inc.Inventors: Rajesh Bhalla, Gopal K Dommety
