  • Patent number: 7865410
    Abstract: A method and apparatus for providing an aggregated account metering system to a computer network service provider resulting in comprehensive detailed subscriber accounting records. Accounting start-stop event data is retrieved from accounting servers. The accounting records are parsed to a first adapter where they are then published on an active information bus. Network flow data is collected from routers throughout the packet switch network environment by network flow collectors. The collectors serve to aggregate and, optionally, filter the flow data. The network flow data is parsed to a second adapter where it is then published on an active information bus. An integrating accounting adapter subscribes to and collects accounting event data and network flow data and correlates this data into a detailed call record that is formatted as desired.

  • Patent number: 7580999
    Abstract: A method for providing remote management and maintenance of a node or service within a data communications network that is activated by the data communications network management system's receipt of signals of an abnormal condition at a node or service or failure to receive operational status signals from a node or service. A control adapter running on a node within a Point of Presence is started. The control adapter is capable of starting all service adapters associated with all services running on the node. Operational status signals and abnormal condition signals are transmitted from the control adapter and service adapters on to an information bus. If a network management control host receives abnormal condition signals, notification is sent to a remote system administrator that alerts of an error experienced by a node or service.

  • Patent number: 7502851
    Abstract: A method for conveying data communications network management information to an umbrella management system whereby network management information events are published on an information bus and received at a subscribing monitor interface located on the information bus. The monitor interface then converts the network management information events into umbrella management system-useable information and communicates the umbrella management useable information to the umbrella management system. In this manner, the umbrella management system is able to import valuable information pertaining to the devices and services that comprise the overall network. The monitor interface includes an adapter located on the information bus that subscribes to network management information events, a converter that formats the network management information events into data useable by the umbrella management system, and a forwarder that communicates the umbrella management system-useable data to the umbrella management system.

  • Patent number: 7370102
    Abstract: A method and apparatus for providing management and maintenance to a node within a data communications network and to the composite data communications network. A network management application is started on a host which may be located at a network operation center. The management application is in communication with network nodes and services through adapters. A master daemon located at a node is activated. The master daemon starts a control adapter running on the node and if the control adapter fails the master daemon restarts the control adapter. The control adapter is capable of starting and stopping all services running on the node. Signals are communicated between the management application, the node and the services by way of adapters. Signaling provides for the exchange of useful event data related to the nodes and services running on the nodes.

  • Patent number: 6263369
    Abstract: A network access point for locally processing an access request is configured to include an information bus, an access event publisher, and at least one local cache having at least one user record. The access event publisher publishes at least one network access event on the information bus during the processing of the access request. The first local cache is coupled to and is responsive to the network access event by updating the user record according to information contained by the network access event if the information includes a home access point ID that corresponds to the first local cache. The network access point may be part of a communications system having a mother cache. The mother cache is coupled to the first local cache and includes user records of subscribers supported by the communications system.
