  • Patent number: 8369329
    Abstract: A Dynamic Hierarchical Address Resource Management Architecture (DHARMA) coordinates a logical hierarchy of address spaces with a virtual topology of network elements using a manageable database environment. Address spaces are apportioned into hierarchical levels in accordance with a network policy. Network elements may be represented as objects, coupled via the logical address space. Both address space hierarchy definition and virtual topology modelling may occur independent from actual network deployment. As a result, multiple address space hierarchy definitions and virtual topologies can be pre-generated and stored for selective use during network deployment. With such an arrangement, a flexible addressing architecture is provided which may advantageously be used in any network that desires dynamic network configuration.

  • Publication number: 20120222085
    Abstract: A method, system and apparatus for allowing media context sensitive SIP signaling exchange and call establishment while denying or challenging any other session description protocol extension dialogs which might not be desired by a user. User client media policy preferences are defined, the user media policy preferences establishing the parameters for evaluating a media session request received by a user client. The user client media policy preferences are provided to a policy enforcement point device, the policy enforcement point device evaluating the media session request received by the user client and applying the user client media policy preferences to the media session request. A user client portal is utilized to gain access to a media policy database, the media policy database providing storage for user client media policy preferences.

  • Patent number: 8176525
    Abstract: This invention provides a method, system and apparatus for allowing media context sensitive SIP signaling exchange (such as voice) and call establishment while denying or challenging any other session description protocol (“SDP”) extension dialogs which might not be desired (such as instant messaging, video, Web broadcasting or pushing, data and/or application sharing and the like) by a user. The method and apparatus may further include defining user client media policy preferences, the user media policy preferences establishing the parameters for evaluating a media session request received by a user client, and providing the user client media policy preferences to a policy enforcement point device, the policy enforcement point device evaluating the media session request received by the user client and applying the user client media policy preferences to the media session request.

  • Patent number: 7764677
    Abstract: The present invention advantageously provides a method, system and apparatus for allocating addresses to secure unique local networks by providing a brokered federated policy and identity management system, the brokered federated policy and identity management system having an address domain manager that allocates network addresses, the address domain manager arranged to interoperate with a network identity management module, the network identity management module providing management of identity at an application level, receiving an authorization from the brokered federated policy and identity management system, and assigning a network address to a unique local network based on the authorization from the brokered federated policy and identity management system. The method, system and apparatus may further include authenticating a user, wherein authenticating a user includes passing an assertion token to a device of the user.
