Definitions

  • a hierarchically distributed network management system is known from US Pat. No. 6,105,061, which has a central network management station and a plurality of decentralized network management stations. Attributes of network objects are stored in the central network management station and are monitored by the central network management station.
  • a control device of the central network management station is provided for the processing of access requests to network object attributes by the decentralized network management stations. The control device of the central network management station accepts the access requests and transmits the requested network object attributes to the respective decentralized network management station. If the requested network object attributes are not stored in the central network management station, the control device of the central network management station forwards the associated access request to selected decentralized network management stations for processing.
  • the hierarchically distributed network management system described in US Pat. No. 6,105,061 essentially only divides network management tasks perceived by configuration management between the central network management station and the decentralized network management stations. Other network management areas, such as error, performance and security management, are not taken into account.
  • an efficient division of network management tasks requires the inclusion of essentially all network management areas, not least with a view to being economical for network operators and owners Operation outtasking. Profitability problems can arise in operation outtasking in particular if operation outtasking services for operating communication networks in countries or regions with a lower wage level are obtained from countries or regions with a higher wage level.
  • the present invention is therefore based on the object of specifying a method for operating a communication network which enables efficient distribution of network management tasks, a network management system which is suitable for carrying out the method, and a suitable implementation of the method.
  • An essential aspect of the present invention is that network operations management tasks that essentially affect all network management areas, such as error, performance, configuration, billing and security management, are structured on the basis of predetermined network operational requirements and can be predetermined according to their structure Network management units are delegated. In this way, it is possible to resolve opposites between a central and a decentralized network management and to combine both approaches on the basis of a cross-network delegation of network management tasks.
  • FIG. 1 shows a network management system in a schematic representation
  • FIG. 2 shows a representation of network management tasks that are structured according to network operating requirements and that are delegated to predeterminable network management units according to their structure.

  • the charging takes place on the basis of an assignment of network resources used and periods of use to the respective network users.
  • the error monitoring system 104 detects, analyzes and eliminates errors in the communication network by observing network resources, while the power monitoring system 105 determines the utilization of network resources and the resulting performance bottlenecks.
  • the access rights management system 101 is provided, inter alia, for setting up or changing services.
  • the access rights management system 101 accepts messages 121 with service orders and converts them into messages 122 with connection orders, which are transmitted to the configuration system 102. Further tasks of the access rights management system consist in the authentication of network users, in the administration of passwords for network resources or services to be protected, and in the granting of access rights.
  • the configuration system 102 is provided for storing information which describes the functional properties and the topological arrangement of network elements relevant for the provision of a service. This information is assigned to the respective service and stored in a network element database 103 assigned to the configuration system 102.
  • the network elements relevant for the provision of a service include, for example, network access points, connections and line connections along an end-to-end network path between two service access points.
  • Functional properties of network elements include bandwidth, supported communication protocols and switching technologies used.
  • the description of the topological arrangement of network elements includes a subdivision of the network elements into node network elements, such as measuring points and switching points, and edge network elements, such as line connections, and preparation as topological information in accordance with a node-edge model.
  • the information stored in the network element database 103 is made available to the error monitoring system 104 and the performance monitoring system 105 in a manner that can be called up. Further tasks of the configuration system 102 consist in initializing or terminating network resources and in setting or changing network resource parameters.
  • the access rights management system 101 transmits a message to the error monitoring system 104 with an order for monitoring the availability of network elements which are specified as relevant for the provision of the respective service.
  • a message 125 with an order for monitoring the quality of service is transmitted to the performance monitoring system 105.
  • These monitoring orders cause the error monitoring system 104 and the performance monitoring system 105 to generate error messages 127 and measurement errors recorded in subnetworks 106, 107, 108. values 128, which are forwarded to the fault monitoring system 104 or the power monitoring system 105 via a subnetwork and transmission technology-specific network operating system 109, 110, 111, with the information stored in the network element database 103 to compare for impermissible deviations.
  • Corresponding network element database information is queried by the error monitoring system 104 or the power monitoring system 105 and transmitted to the latter as messages 126.
  • the error monitoring system 104 or performance monitoring system 105 generates a message 129, 130 about an under-performance of the service, specifying the service concerned.
  • the availability and the quality of service are monitored in accordance with a quality of service agreement made between a customer and a network operator. Therefore, only information relating to the network elements specified as relevant by a service level agreement for the provision of a service is stored in the network element database 103. In addition, error messages or measured values are only recorded for the network elements specified as relevant by the service level agreement for the provision of the service.
  • a message 123 with an order for monitoring a quality of service agreement is transmitted from the access rights management system 101 to the error monitoring system 104. This means that a recording of error messages or measured values for network elements specified as relevant by the service level agreement for the provision of a service is already initiated by the establishment or change of the corresponding service.
  • the power monitoring system 105 transmits an alarm message 129 about a violation of a quality of service criterion to the error monitoring system 104 and converts it there into an alarm message 130 about a violation of a quality of service agreement.
  • An error message 127 is converted in the error monitoring system 104 directly into an alarm message about the violation of a quality of service agreement.
  • the alarm message 130 contains a statement about the availability of the service or the quality of service and is transmitted to a subnetwork-specific network operating system 109,110,111, which is assigned to the subnetwork 106,107,108 and in which an error or a violation of the quality of service criterion occurs, in order to remedy the underperformance of the service.
  • the respective network operating system 109, 110, 111 converts the alarm message 130 into a control command 131, which is transmitted as a message for the elimination of underperformance to a selected control device, not explicitly shown, in the respective subnetwork 106, 107, 108.
  • the respective network operating system 109, 110, 111 reconfigures the network element affected by the service underutilization elimination with access to the information stored in the network element database 103. This also applies to the configuration of a network element when a service is set up, changed or deleted.
  • the alarm message 130 about a violation of a quality of service agreement is also transmitted to the access rights management system 101. There it is prepared with customer data and converted into a report 132 about compliance with or violation of a service level agreement.
