Definitions

  • the present invention is related to a system and method for managing the administration of infrastructures. In particular, it is related to a future proof managing method and system of a telecommunications infrastructure.
  • the present telecommunications infrastructure is sometimes referred to as "the worlds biggest machine”. This infrastructure involves a lot of different networks like fixed copper or fibre networks, wireless networks (GSM, GPRS, UMTS, fourth generation networks) and satellite networks. The complexity of contemporary infrastructures is dealt with by structuring the infrastructure in detail.
  • Still another problem is that an infrastructure has to cope with yet an unknown future. New technological improvements as well as new services may have to be implemented. The administration of the infrastructure therefore has to be flexible enough to be easily adapted to new developments.
  • Still another problem of existing administration systems for infrastructures is that the management of such a system is very time consuming and therefore expensive.
  • the present invention aims to provide a novel method and system to administrate all possible changes occurring in an infrastructure accurately and fastly, while being capable of coping with future developments.
  • the administration method will no longer constitute the bottleneck for introducing new products or services or the adoption of new technologies.
  • An infrastructure is defined as a coherent physical entity of means that offers lasting services, e.g. telecommunication services, to parties, e.g. consumers.
  • the infrastructure consists of infrastructure objects.
  • An infrastructure object is defined as an object (or hardware) creating networks in one or multiple aspects.
  • ISO's are ducts, cables, cable jackets, fibres, dividers, antennas, filters, multiplexers, modems etc.
  • ISO's can be coupled to each other by different aspects.
  • An aspect is defined as a specific function the infrastructure accomplishes from a particular point of view.
  • the relevant aspects of an ISO cable can e.g. be identified as a surroundings aspect (location, property of the ground, condition of the ground), a protection aspect (measures taken against mechanical violence, measures taken against humidity), an arrangement aspect (star groups, layers, colours) and a material aspect (individual fibres of the cable). Whether the consideration of a particular aspect is significant depends on the services that will be offered to customers. These services might change with time, so the aspects are subject to change as well.
  • One of the elements of the present invention therefore is the implementation of an aspect generator in order to obtain a future proof system.
  • the aspects constitute networks, the configuration of which networks depends on the aspect that is considered. Networks are coupled by different aspects of an ISO.
  • aspects may be identified which each view a single function of the infrastructure, and which also provide an exploitable network.
  • the aspects are connection, signal, conduction and space.
  • the aspect space views distances and dimensions of the infrastructure.
  • ISO's which give space or provide room for other ISO's, such as trenches, sewer channels, MOKAP's, street cabinets, etc.
  • the unit of request for or offering of space is expressed as a one, two or three dimensional measure.
  • Some ISO's may require space, but may also provide space.
  • ISO's requiring space, but unable to provide space (such as cable pieces) are the highest level clients, which can not be server within this aspect.
  • the aspect conduction is aimed at the (physical) system in which signals are 'trapped'.
  • the system provides the possibility to address signals, but also determines the quality of the signal communication.
  • the measure is expressed in dB
  • the ISO's usable in conduction networks are wires, bonds, pins, pairs, quads, fibres, etc. Most of these ISO's also require space, and play an important role in the client/server relations between the aspects space and conduction.
  • the aspect signal views networks which in any form transport electrical, RF or optical signals.
  • Carrier waves are signals at the lowest level, most basic server level.
  • the highest client level within this aspect comprises signal streams compiled according to one of the present transport protocols (IP, ATM, STM1, etc.).
  • IP Internet Protocol
  • ATM ATM
  • STM1 Serial Bus
  • ISO's playing a role within this aspect are numerous equipment and equipment gates.
  • connection describes the highest level of telecommunications service, i.e. the possibilities for customers (at end nodes) to exchange messages with other clients.
  • Connection comprises all possible forms of connection, i.e. fixed/dial, analog/digital, voice/data/fax, point-to-point/multi-point/pint-to-multipoint, etc.
  • ISO's in this aspect can be found in peripheral equipment (usually at the customer's premises)
  • networks are defined as non-physical entities, constituted by aspects.
  • a network can be represented as a graph comprising nodes and edges. This is shown in figure 1.
  • the infrastructure constitutes the substrate that carries the various networks.
  • a network service can be defined as a path through a particular network that serves as an ISO for a higher aspect.
  • a path is defined as the route through a network. Such a path runs through the network from an end node to an end node, and crosses each edge or node only once. Therefore a path can be said to be established by the vertices (nodes) and edges.
  • a path comprises both capacity and routing, capacity indicating whether the path is part of a supply, and routing indicating whether actual routing via the path exists. For users of the present method, the edges and vertices are never visible, only the ends of a path in terms of ISO's.
  • characteristics associated with the at least one infrastructure object are stored using client/server relations by means of a path.
  • the infrastructure object PE tube forms a path.
  • This path carries a conductor tube, which in its turn forms a path which allows to carry a wire, etc.
  • attributes may be identification, name, path meant for capacity/routing, first edge (A-side). last edge (B- side), intermediate edges, and path lock (exclusively for defined edges).
  • attributes may be identification, infrastructure object, A-side/B-side, server path, and edge lock (exclusively for use by constructed path).
  • Node attributes may be identification, ISO.

  • the telecommunication infrastructure can for instance be chosen to exhibit eight aspects 11...18 as shown in figure 2.
  • the eight different aspects within this model are surroundings 11, protection 12, arrangement 13, material 14, circuit 15, signal 16, service-carrier 17 and service 18.
  • Every aspect 11...18 constitutes its own network 21...28 that is build of nodes (or vertices) A...H and edges 1...9 as shown in figure 1.
  • the networks 21...28 effectively come into existence as a derivative of placing and coupling of the ISO's 20 that constitute the infrastructure. Networks therefore can be said to be created indirectly.
  • the placing and coupling of ISO's 20 can create networks 21...28 within different aspects 11...18 simultaneously.
  • This method of describing the infrastructure is repeated for each identified aspect 11...18 and therefore provides an excellent foundation of building a structured, accurate and future proof administration system for a particular infrastructure.

For the user of the present system, only the end points of a path in terms of ISO's 20 are communicated and not the vertices and edges.
  • an ISO-classification can be made.
  • ISO's might be of restricted use. These restrictions are recorded in the ISO characteristics and in the business rules establishing the use of the ISO for each application. E.g., for a Y-connector the angle made can be recorded and the business rule can state that the angle should be larger than 90 degrees for using a guide tube.

  • the ISO's 20 are characterised by a number of attributes, such as identification, material, cost, location, etc.
  • the geographical location of an ISO 20 is always a point location and is determined by means of addressing. A single location can be addressed in several ways, i.e. a location might have several addresses. The size of a location can be expressed by the accuracy of the address. Formal and informal addresses can be distinguished, the former being discrete, systematic and zoomable (co-ordinates, global positioning system (GPS) etc.), the latter being non-zoomable (Postal Code, relative addressing).

  • formulas for formal addresses and translation tables for informal addresses the different types of addressing may be interlinked and exchanged.
  • no translation table is required as these are linked to an ISO having a formal address.
  • Formal addresses are discrete, systematic and zoomable, and formulas may be used to convert one type of formal addressing to another type. Examples of formal addressing methods are WGS 84, which is used in e.g. the Global Positioning System GPS, and Rijkscoordinates, which are used in The Netherlands, but require accurate maps and measuring instruments to use.
  • Informal addresses are usually not zoomable. Examples of informal addresses are Postal Codes, relative addressing (referring to another object or ISO having a formal address), or free textual addressing. Translation tables may be used to convert an informal type address to a formal type of address. Relative addressing may use naders to further detail the address of an ISO.
  • a nader may comprise three parts: a textual indication ('three steps to the left'), a formal indication of the type of relation ('next to', 'in'), or a formal reference to another information source (e.g. a hyperlink or a binary large object).
  • a building has a formal address in Rijkscoordinates.
  • a switchboard is located (relative address).
  • the switchboard has connectors, which may be addressed as connector a in switchboard. In this manner, one can zoom to details in an increased manner.
  • the present invention is preferably implemented using Object Oriented technology.
  • Object serialisation allows the state of an object to be recorded, thus allowing administration of an installed base (infrastructure) and also planning of future infrastructures.
  • the toolbox of the implementation is also able to keep versions of the infrastructure which may be merged into the installed base.
  • Specialisation techniques are used to extend a generic core into an infrastructure administration, resulting in inheritance.
  • specialised subclasses can be created, which can use its parent's functionality and data, and which can be used instead of any of its ancestors.
  • a subclass can take any 'shape' of its ancestors, also indicated by polymorphism.
  • Object-oriented technology also allows encapsulation, i.e. the implementation of an object is hidden behind a well- defined interface, to make a clear distinction between the specification and implementation of an operation. This way, the implementation of an object can be changed without changing the parts that use the interface.
  • the method and system have to be able to administer any kind of infrastructure.
  • the system is based on a very generic core or kernel 61 (indicated by the acronym DARK (Delden ARchitecture Kernel)) that is able to administer any kind of network modelled using graph theory.

  • the proposed system is a distributed client/server-based system.
  • the purpose of interface distribution is to allow client systems to talk to a remote system as if it were local. Other systems might use the proposed system to administer their infrastructure.
  • Future GIS systems can use the proposed system as the source of their GIS data.
  • the interface of the proposed system (the interface of ISO's, tracing, versioning and spatial functionality) is preferably distributed to the client systems using messaging middleware 67 (e.g. GALA, TIBCO, Tuxedo).
  • middleware 67 e.g. GALA, TIBCO, Tuxedo
  • Distributed computing standards like EJB, CORBA, RMI or DCOM let the client systems talk to proxies and can be used as well.
  • An advantage of this option is that these standards hide the necessary messages to distribute the request.
  • the toolbox might be able to do distributed cache management (i.e. for GIS applications), indicated by the cache 68 in the middleware layer 67.
  • the proposed system consists of the following components:
  • the architectural kernel (DARK) 61 is responsible for adding or removing vertices and edges and consistency.
  • the edges and vertices refer to ISO's 63.
  • the Generic ISO manager 62 builds on the functionality exposed by the architectural kernel and adds the generic functionality used by all specific ISO's 63.
  • Fig. 7 shows a different representation of the basic system architecture. Networks comprising vertices and edges have been identified as a repetitive phenomenon for each and every aspect 11...18 of an infrastructure. Therefore the method and system are based on the network functionality 71 performing operations as Creating, Reading, Updating and Deleting (CRUD) the vertices and edges and tracing paths through networks.
  • CRUD Creating, Reading, Updating and Deleting
  • the functionality of every ISO 20 can be divided into a generic and a specific part.
  • the generic part 72 can be identical for all ISO's 20 and comprises e.g. the CRUD ISO. Besides this generic ISO-functionality the generic part supports spatial data (i.e. geographic data) and versioning (i.e. support of different versions that arise due to planning of new parts of an infrastructure).
  • the user of the present method may select a specific view by selecting an aspect.
  • infrastructure objects may be selected.
  • a number of operations may be executed, such as create the default aspects of a specific ISO, load and save.
  • the default aspects may be given a value and other attributes may be added.
  • the system provides a basic tracing functionality to trace through the network in a systematic fashion. Network tracing is used to find a path in a network.
  • the trace package preferably does not make any assumptions about needing to cache the entire network in proprietary data structures (either in memory or on disk) before a trace can be carried out.
  • the trace package can be able to discover connections as it traverses the network. This discovery preferably uses the same database handle as the core code to ensure that transactional integrity is maintained.
  • the supply of "elements connected to the current element” could be either via direct database access, or via the object access routines within the system itself.
  • the tracing functionality can be used e.g. to compute the lowest cost route through the network, irrespective of the way the costs are measured.
  • the trace functionality is packaged as a service within the core of the system object model. Integration of the trace functionality within the core of the system will most easily be achieved via a trace toolkit or library that can be called from the core.
  • the functionality to administer geographical data is provided by the toolbox, so that the system can be used as GIS server for future GIS applications.
  • Current GIS applications include their own infrastructure model, which is very focussed on the physical representation of the infrastructure. This results in redundant data storage and mixed definitions causing inconsistencies and fouled data.
  • ISO's 20 such as cables, tubes etc.
  • aspects etc. E.g. different types of objects in the domain have to be described, the objects need to be classified etc.
  • plug-ins as shown in the figure (blocks 73, 74). Additional functionality 75 as e.g. reporting functionality or additional tracing functionality can be obtained using the plug-in mechanism as well, even as a later addition to the system. Together with the core functionality the plug-ins provide a complete working system for administering infrastructures, which may e.g. provide answers to questions and execute actions. In order to provide a generic core or kernel and specialised ISO's the system may be designed and built using object oriented technologies.
  • the system can be built using object-oriented techniques known to the person skilled in the art to obtain the flexibility needed to implement new technologies without needing to alter the data model.
  • the system can use some form of database.
  • object databases provide the most natural environment for storing objects.
  • relational databases might be used as well.
  • An important reason to use object oriented databases is that they offer complex object support, rich many-to-many data element relationships, inheritance of characteristics and similar requirements not well met by conventional table-oriented designs.
  • the database system can be equipped with concurrency control, recovery and backup facilities, distributed database capabilities, performance monitoring and/or security provisioning means. There are various ways to handle the spatial storage of the files.
  • a key determinant of the architecture of spatial storage relates to how the data are spatially indexed and spatially filtered on retrieval.
  • the system is able to support long transactions that may span multiple update sessions of the database, i.e. versioning. Versioning e.g. allows multiple "what if analysis to be run against the same set of data or allows updates to be hidden from other users, whilst still being stored in the main database. Using long transactions does not mean that normal or short transactions are not used. Versioning can be implemented as part of the database core as well as an overlay on top of the database. Graphic caching can be provided to speed up the performance of the system.

  • the Stock-building platform sends a request to the plug-in via the specific ISO-interface as shown in fig. 8C.
  • This request comprises the instruction "CONNECT TUBE” and parameters "TUBE ID: 20, TUBE ID 40, TUBECONNECTION S2". Examples of other instructions are PLACE CABLE, CONNECT CABLE, INSTALL DIVIDER etc. These are specific instructions for the individual ISO's.
