  • Patent number: 9166884
    Abstract: A method is provided for a network location service in which one or more packet forwarding devices in the network collect and maintain location data for the devices/users currently connected to a network. The data is maintained locally in each packet forwarding device and may be provided on demand to a network/business application, such as emergency 911 services or a location-based security or personalization system. The location data is provided in real-time or near real-time using an in-band channel communication and/or over the Internet using a standard transport protocol, such as HTTP/S and SOAP web services.

  • Patent number: 9098500
    Abstract: In one embodiment of the present invention, a method is provided for maintaining and storing revision history of a design. The method includes, in response to a first control input by a user, determining, by a processor, module definition parameters that have changed from a design file. The changed module definition parameters are stored in the design file. For each changed module definition parameter, revision data are appended to revision history data. The revision data indicates a revision identifier, a module definition parameter identifier, and an updated value of the changed module definition parameter.

  • Patent number: 8279874
    Abstract: A self-configuring network comprises network devices that are automatically provisioned with appropriate network resources upon the occurrence of a network event. A profile containing one or more commands to provision a network device with appropriate network resources is deployed to selected connecting devices. The selected connecting devices are targeted for deployment based on the network device and/or port groups to which they belong as determined from a network management system. The profile is bound to the selected connecting devices and affected ports as well as the network events that will trigger execution of the profile on the devices where they are deployed. A graphical user interface and profile information database may be used to facilitate managing the profiles, targeted devices/ports and associated network events.
