Definitions

  • Novel telecommunications services are often based on different technologies and their provision requires the configuration of resources in networks of different technologies.
  • a connection is set up via an ATM access network (Asynchronous Transfer Mode).
  • an access router in the IP network Internet Protocol is configured for an ADSL connection.
  • a connection via an ATM access network is also set up to provide an ISDN subscriber line using SDSL technology (Single Line Digital Subscriber Line).
  • SDSL technology Single Line Digital Subscriber Line
  • a transition to a fixed telephone network and an ISDN subscriber in the fixed telephone network are set up.
  • Further examples of services that are provided in heterogeneous network environments are VPN (Virtual Private Network) or LAN-LAN couplings (Local Area Network) via xDSL technology.
  • network elements of different technologies have to be configured by a service provider.
  • These network elements include DSLAMs (Digital Subscriber Line Access Multiplexer), ATM switching nodes in the ATM access network, IP routers in the network of an Internet service provider (Internet Service Provider - ISP) and telephone switching systems in the fixed telephone network.
  • DSLAMs Digital Subscriber Line Access Multiplexer
  • IP routers in the network of an Internet service provider (Internet Service Provider - ISP)
  • telephone switching systems in the fixed telephone network For different subnets there are associated network operating systems (Network Management System), each with different databases with information about the network elements assigned to the respective subnet. instruments.
  • Network resources formed by the network elements are configured via the network operating systems.
  • network elements to be configured have been controlled on a sub-network basis on the basis of information about these network elements in sub-network and switching technology-specific databases.
  • switching techniques for example connection, packet or line-oriented switching
  • manual synchronization and administration is often necessary.
  • the present invention is based on the object of specifying a method, a communication system and a computer program for the uniform provision of services in heterogeneous network environments in which different switching techniques are used.
  • An essential aspect of the present invention is a summary of configuration-relevant information describing their functionality in a cross-subnetwork manner in a network element database.
  • network elements can be configured in a system-uniform manner when a service is set up, changed or deleted by a network operating system that accesses information stored in the network element database.

  • Figure 4 is a schematic representation of a data technology modeling of network levels.
  • a data model is used for a communication system that is independent of switching techniques used in subnetworks.
  • This data model enables rule-based provision of services based on a single network element database with an overall system perspective.
  • subnets with connection, packet and cell-oriented switching techniques can be described in a data model.
  • Network elements in their functionality, configuration-relevant information that is stored in subnetwork-specific databases, are reduced and generalized to such an extent that administration of essentially all services is possible.
  • Existing databases are not replicated or replaced, for example, but the information they contain is mapped to a generic model.

  • the model maps the network topology with all network transitions.
  • existing connections are mapped, including the resources used as a result.
  • All network hierarchies and thus the network level structure are known in the data model, for example ATM over SDH (Synchronous Digital Hierarchy), IP over SDH, Voice over IP.
  • the data model specified for the network element database comprises the following objects:
  • Network - represents the overall network, which can consist of one or more subnetworks
  • Subnet maps the technology to specific subnets and contains endpoint network elements of different types
  • Gate Network Element represents the network elements that provide resources for connection endpoints; only network elements that are on the edge of a subnet are modeled, i.e. those network elements which provide access points for subnetwork connections or subnetwork connections;
  • Access point is contained in objects of the type end point network element (Gate Network Element) and models both connection resources, for example the "containers" for connection end points or physical connections, as well as connection end points themselves;
  • Subnet connection (Cross Domain Connection) - models network transitions between subnets; • End-to-end connection - represents connections that consist of a concatenation of subnetwork connections and subnetwork connection;
  • Connectivity models connectivity between two access points; in contrast to a connection, at least one segment is based on one
  • an end-to-end connectivity can be from a connection depend which implements communication on a portion of an end-to-end path; • Profile (Profile) - specifies parameters of subnetwork internal connections, end-to-end connections and connectivity.
  • Each end-to-end service consists of two access points (resource points), which are known in the data model, and a service profile. To provide a service, only this information, the two endpoints and the

  • the end-to-end service requires either the provision of connectivity or an end-to-end connection. In the case of a connectivity, it must be checked whether it needs one or more end-to-end connections in the given network scenario. If not, only the connectivity object has to be created in the database. Otherwise, the two endpoints must be determined for the end-to-end connection (s) and the following steps carried out, as well as for a directly requested end-to-end connection. 5. The path of the end-to-end connection through the network must be determined. This is based on knowledge of the network topology, in particular the network transitions, and knowledge of the free network resources at the access points of the

  • the rules for service provision can be based on the service-oriented data
  • the data model makes it possible to determine all required network resources and to control the configuration in the network.
  • the rules define the individual steps for each supported service and, depending on the network topology, which are required to provide the service.
  • the configuration in the sub-networks can be done by generating work instructions to the network management system, or fully automated if the interfaces are supported.
  • a service view is decoupled from the network view, which enables faster provision of the services.
  • the provision of a service can be automated end-to-end, since all network gateways are known. Manual synchronization of the gateways is no longer necessary.
  • the above-described method for providing services in a communication system is implemented by a computer program that can be loaded into a working memory of a data processing system and has code sections, the execution of which carries out the steps described above when the computer program runs in the data processing system.

Abstract

L'invention concerne la fourniture de services dans des systèmes de communication comprenant au moins un premier et un deuxième sous-réseau dans lesquels des techniques de transmission différentes sont utilisées. Selon l'invention, des informations liées à la configuration et décrivant la fonctionnalité d'éléments de réseau sont sauvegardées dans une base de données d'éléments de réseau, globalement pour les sous-réseaux. En cas d'installation, de modification ou de suppression d'un service, des éléments de réseau sont configurés par un système d'exploitation de réseau accédant à des informations sauvegardées dans la base de données d'éléments de réseau.
