Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • a subscriber line network which as a rule comprises a plurality of subscriber lines.
  • subscriber lines consist of conventional copper wires (a / b wires).
  • the individual subscriber lines are bundled and brought to the local exchange in question.
  • the aim is therefore to use the existing subscriber line networks for the transmission of data and information of higher bit rate services.
  • own transmission methods have to be developed.
  • Such transmission methods are, for example, the so-called xDSL (ADSL, HDSL etc.) methods.
  • the copper wires of the subscriber line network can thus be modified by suitable transmission technology. took up to transfer rates in the Mbit / s range through out ⁇ be used.
  • the ADSL transmission method is asymmetrical. This means that a higher bit rate in a preferred direction can be chosen at the expense of a lower bit rate in the opposite direction. For example, up to 6 Mbit / s can be sent from the network to the subscriber and 2 Mbit / s from the subscriber to the network. The disadvantage of such a procedure is that the preferred direction once selected cannot be changed dynamically.
  • the invention has for its object to show a way how a bidirectional transmission between network and subscriber can be flexibly controlled.
  • An advantage of the invention is in particular that an interface between the application level and the physical transmission is provided, to which control data are supplied by evaluating protocols. This has the advantage that the use of an xDSL method such. B. ADSL preferred direction can be reconfigured by higher protocols.
  • the interface should preferably be arranged in the local exchange. Control data is provided via this interface, by means of which the preferred direction of the ADSL transmission method is reconfigured. that can. The reconfiguration is triggered by higher protocols.
  • the evaluation of resource management cells in ATM networks or IP'Flow Detection 'mechanisms can be considered as higher protocols. If the evaluation of a higher protocol layer reveals the need to change the required bit rate in a certain direction, the xDSL link will be reconfigured accordingly.
  • the physics, i.e. the copper wires, are always optimally adapted and used according to the needs. Depending on the type of user application desired, the network-to-subscriber direction or the subscriber-to-network direction will have the higher transmission rate. Symmetrically divided bit rates are also possible.
  • ATM-based networks provide for requesting a specific transmission rate from the network by means of the signaling.
  • These signaling protocols allow the use of asymmetrical connections. If, for example, the case of a ⁇ file download is considered by a server, a higher transmission capacity from the network to the subscriber is required. On the other hand, if, for example, ⁇ video telephony is desired, the same, as high as possible transmission capacity will be necessary for both directions. In this example, the evaluation of the signaling protocols automatically adjusts the physical transmission rate.
  • the RM cells contain information about the network load (Congestion Indication Signals). This information is used to set the bandwidth via the interface between the application level and the physical transmission. In the event of information being transmitted over the Internet, reconfigurations can be carried out using IP 'flow detection' mechanisms. It is also possible to set the bandwidth depending on the protocol used by the application layer.
  • the method described here can be combined with the known adaptation methods (that is, automatic identification of the maximum possible transmission rate via existing wires). Furthermore, the basic idea presented here can also be extended to other areas, for example to non-line-based transmission methods.

Abstract

Les procédés de transmission connus à présent dans la zone de raccordement d'abonné, tels que xDSL par exemple, ne permettent pas de reconfigurer la voie xDSL initiale. Afin de parvenir à une plus grande souplesse, il est prévu de reconfigurer la voie xDSL de manière dynamique par des protocoles plus importants.
