Definitions
- the invention relates to a method and an arrangement for configuring at least one network unit assigned to a network node (DSLAM).
- DSLAM network node
- Modern communication networks usually consist of a plurality of interconnected network nodes.
- a current telecommunications network is shown schematically in FIG.
- the main network of the entire telecommunications network is a broadband network, which can be implemented, for example, as an IP network (IP: "Internet Protocol”)
- IP Internet Protocol
- Main network also referred to as the backbone of the network
- DSLAM Digital Subscriber Line Access Multiplexer
- TN1, TN2 to TNk The individual participants connected to DSLAMl are denoted in FIG. 1 by TN1, TN2 to TNk. Further subscribers, for example connected to DSLAM2 and DSLAM3, are not shown in FIG. 1 for better clarity.
- Each of the subscriber lines (DSL1, DSL2, ..., DSLk) is initially connected, on the exchange side, to a separate network unit, for example in the DSLAM1, a so-called "line card" (LCl, ..., LCl) TNl to TNk are for example with a first linecard LCl connected. Accordingly, further subscriber lines can be connected to the further line cards LC2 to LCl assigned to the DSLAMl (not shown in FIG. 1).
- a DSLAM usually contains a plurality of these line cards (LCl,...,. LCl), which are usually plugged into dedicated slots or slots within the corresponding DSLAM.
- the individual line cards (LCl,..., LCl) contain, for example, a plurality of subscriber ports (POl,..., POm) to which the individual subscriber lines (DSL1,..., DSLk) can be connected.
- POl subscriber ports
- DSLk subscriber lines
- One task of the line cards (LCl, ..., LCl) is to control and monitor the data flow on the subscriber lines (DSLl, ..., DSLk). For this task, information about the properties of the individual subscriber lines (DSL1, ..., DSLk) is required on the line cards (LCl, ..., LCl).
- This information is usually stored in a non-volatile memory (for example directly in the DSLAM1) and is transmitted to the individual line cards (LCl,..., LCl) during a system start by a central module arranged in the DSLAM1.
- a DSLAM contains several central modules (ZBG) responsible for a certain number of line cards (LCl,..., LCl).
- the individual line cards (LCl,..., LCl) are thus individually configured during a configuration process in accordance with the information transmitted by the respective central module (ZBG). Subsequently, a corresponding initialization of the individual chipsets arranged on the line card (LCl,..., LCl) begins in the line cards (LCl,..., LCl).
- the object of the invention is, inter alia, this
- This object is based on a method according to the
- configuration data are stored centrally in the network node and / or stored in the at least one network unit in a decentralized manner. Furthermore, it is checked during a booting process, if at least a part of the centrally stored in the network node and the at least one network unit locally stored configuration data is at least approximately identical, and carried out the configuration of the at least one network unit depending on the result of the check.
- the essential advantage of the invention is that the time required for the configuration of network nodes or network units assigned to them is minimized.
- the configuration of the at least one network unit is advantageously carried out according to the methods described in US Pat at least one network unit decentrally stored configuration data - claim 2.
- the configuration data stored in the network node are transmitted to the at least one network unit and stored there, and the configuration of the at least one network unit takes place in accordance with the transmitted configuration data.
- the check is carried out, for example, using keys that are uniquely assigned to the configuration data, wherein it is checked whether at least a part of the keys stored in the network node and in the at least one network unit is at least approximately identical - Claim 4.
- the keys are advantageously stored in the network node, are transmitted to the at least one network unit and / or stored there and each contain information about the MAC address and / or slot number of the network unit and / or storage time of the key claims 5 and 6. By using such information, the network entities can be uniquely identified.
- Figure 1 is a schematic representation of a current, already mentioned in the introduction to the telecommunications system and
- FIG. 2 shows a flow chart for explaining an exemplary sequence of the method according to the invention.
- a global unique key is advantageously generated in a configuration operation initiated by the central assembly.
- shelf The MAC address of the shelf ("shelf") of the DSLAM in which the central module and the corresponding line cards are located, the slot number of the configured line card within the corresponding shelf (1 ... 1), the storage time of the configuration and optionally
- the MAC address is a media access control address, which is a unique, unique, 48-bit hardware address that uniquely identifies a node in a network. Address consists of a vendor ID and an adapter ID, so in this example it clearly refers to at least the shelf in which the central module and the associated line cards are located, and this is the only fixed identification option with regard to the subscriber lines Assemblies in the DSLAMs can be freely plugged in or the positions exchanged, for example in a DSLAM several shelves for central modules and the associated line cards can be present.
- the slot number in turn contains information about the position of a line card within a shelf. For example, a shelf can contain a plurality of individual slots or slots (1 to 1), the slot number correspondingly indicating the position of the corresponding line card 1... 1 in the shelf.
- the key may also contain information about the storage time of the configuration or the startup process, for example, which makes subsequent configurations or startup processes distinguishable from other configuration (and startup) processes.
- a random number can be inserted into the key. This contributes to an increase in security, since the probability that two identical keys are generated, for example due to errors in the generation or transmission of the key, can be further minimized or completely ruled out by an individually generated random number.
- the key generated according to the invention is non-volatile stored both on the central module and on the corresponding line card.
- the key is generated, for example, in the DSLAM, for example in the central module, and then transferred according to the invention, for example together with the assigned configuration information to be transmitted to the corresponding linecard.
- a first configuration process ie, for example, during a first initialization of a DSLAM
- the information necessary for the configuration of the individual line cards or for the initialization of the corresponding chipsets is transmitted to the line cards from the central module according to a current method.
- the line cards are then used to initialize the chipsets, as explained in the introduction to the description.
- the transmitted configuration information or configuration data are stored non-volatile respectively on the respective line cards and in the DSLAM, advantageously in the relevant central module.
- both the key stored on the line card itself and the key stored on the central module for the corresponding line card to be configured are first of all read out (step 201).
- step 202 the two keys are subsequently checked. In this example, this means that it is examined whether the two keys read out are identical.
- the configuration information used for the last configuration and stored nonvolatilely on the line card for re-initializing the chipsets of this line card can be used.
- the line card is thus able to initialize the corresponding chipsets independently (step 203).
- step 202 If, however, it was found in step 202 that the two keys read out are not identical, this means that the configuration data assigned to each of the keys is not identical, e.g. the configuration data stored on the linecard are obsolete. Thus, a re-configuration of the corresponding line card by the central module must be performed. In this case, the configuration information required for the configuration of the line card is thus transmitted from the central module to the line card. In addition, as described above, an up-to-date key representing the new configuration information is generated. This is stored centrally in the DSLAM and also transmitted to the linecard. This is shown in Fig.2 mutatis mutandis by the corresponding steps 205 and 204, respectively.
- initialization of the chipsets according to the newly communicated configuration information may be started on the linecard (step 206). Said configuration information and the generated key are then stored non-volatile again on the line card in addition to the storage on the central module (step 207).
- the time required for initialization can usually be drastically reduced. Since only those linecards need to be provided with new configuration information that has changed since the system was last started or the last time the system was booted, most line cards can transfer the configuration information from the central module to the linecard and confirm the line configuration completed configuration omitted.
- Changes in the configuration information for a single linecard may be, for example, the result in the following reasons.
- a so-called offline configuration configuration actions can be performed while the line card in question is not present.
- the central module sends the configuration information stored thereon and the associated key to the corresponding line card, whereupon the configuration is carried out accordingly and the configuration information and the key are stored.
- the line card in question is in principle one of the original configuration operations described above. This means that in these cases a new key corresponding to the current configuration information is generated, which is stored both in the DSLAM and in the line card.
