  • Patent number: 7792042
    Abstract: In an embodiment, a system and method which monitors a signaling plane for error events among one or more network nodes in a converged network. The system and method classifies and calculates, based on user defined parameters, a threshold value or percentage of error events which occur within a desired amount of time and automatically triggers an alert in the network that a potential network connectivity problem exists in the transport plane. In an embodiment, the trigger automatically initiates troubleshooting procedures to solve the network connectivity problem.

  • Patent number: 7660983
    Abstract: An approach for establishing secure multicast communication among multiple event service nodes is disclosed. The event service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the event service nodes include the group session key and the private keys of the event service nodes that are members of the multicast or broadcast groups. The private keys provide unique identification values for the event service nodes, thereby facilitating distribution of such keys. Because keys as well as key version information are housed in the directory, multicast security can readily be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service.

  • Patent number: 7502927
    Abstract: An approach for establishing secure communication among multiple multicast groups using a multi-master directory is disclosed. The multi-master directory is on a per object and per attribute access controls basis. The event service nodes, which can implemented as event servers, are distributed throughout an enterprise domain. The attributes of the event service nodes include the group session key and the private keys of the event service nodes. A standardized authentication service is used to register publishers and subscribers. These publishers and subscribers can individually belong to multiple multicast groups under a readily scalable, secure network architecture.

  • Patent number: 7383436
    Abstract: An approach for establishing secure multicast communication among multiple multicast proxy service nodes is disclosed. The multicast proxy service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the multicast proxy service nodes include the group session keys that are members of the secure multicast or broadcast groups. Because keys as well as key version information are housed in the directory, multicast security can be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Multicast proxy service nodes may obtain current key information from a local copy of the replicated directory.

  • Patent number: 7197125
    Abstract: A method and apparatus are disclosed for modifying a subscription of a subscriber to a telecommunications service based on subscriber information and service information that are stored in a directory repository. A directory-enabled service selection framework is coupled to the directory repository for receiving stored information therefrom. The directory-enabled service selection framework receives a request to identify one or more services to which a subscriber is subscribed, based on a prior request to modify the subscription of the subscriber to the telecommunications service. A list is generated of the one or more services to which the subscriber is currently subscribed, based on group membership of the subscriber, one or more roles occupied by the subscriber, and authorization information associated with the subscriber that is stored in the directory repository.

  • Patent number: 7010600
    Abstract: A method is disclosed for managing network resources in multiple administrative domains. According to the method, a user is authenticated in a first administrative domain. A token is generated for the user that identifies the user as being assigned a role. The token is configured to identify the user by the role to a component of a second administrative domain. When the user requests a resource of the second administrative domain, its component examines the token and the role to determine whether to grant access to the resource. As a result, the second administrative domain may grant the user access to its resources without re-authenticating the user in the second administrative domain.

  • Patent number: 6917944
    Abstract: A method is provided to configure access to a plurality of data repositories. The data repositories each provide data objects for applications operated by users. A request is received to access data objects in the plurality of data repositories. The request may specify a parameter. Metadata is retrieved that characterizes a portion of the data objects stored in each data repository. One or more objects are selected from the data repositories using the parameter in the request and the metadata.

  • Patent number: 6587874
    Abstract: Client network devices and configuration servers are used together to automatically configure the client network devices. Configuration information for multiple network devices is arranged in a multi-level directory. Leaf nodes in a hierarchical directory correspond to specific network devices. Configuration information associated with such leaf nodes is specific to the associated network device. Configuration information common to a group of network devices is provided with nodes at higher levels in the hierarchy. All network devices grouped under such higher levels inherit the configuration parameters from the higher level nodes. During configuration, all nodes from a leaf to the root of a directory are traversed. The parameters associated with each node are aggregated to obtain a set of parameters provided to the client network device. These aggregated parameters are used to automatically configure the client network device.
