Description

  • TECHNICAL AREA
  • The present invention relates to a gateway device for the intercommunicating data transmission connection of hardware components that are integrated or can be integrated into different data communication networks. The invention further relates to a method for converting data of an input data stream present in a first data communication standard into data of a data of an output data stream present in a second data communication standard. Finally, the invention also relates to a computer program product for carrying out the steps of such a method.
  • BACKGROUND OF THE INVENTION
  • Especially in the military field, there are a variety of communication standards that serve for the exchange of data (information) to other same or different communication systems having data communication networks. Examples of such communication standards are, for example, "Link 11", "Link 16", "VMF", "ADATP 3". Each individual military communication system usually only controls one or a few of these communication standards, so that an efficient exchange of information between different military communication systems, the so-called interoperability, is generally not possible. In addition, the communication networks are mostly static or require at least a lot of time to change the network topology or to reflect changed hierarchies.
  • To establish the interoperability between military communication systems, usually new communication protocols (data communication standards) are subsequently implemented in the computers of the military communication systems in elaborate upgrade procedures. Alternatively, specific translator boxes are known which translate a defined network protocol, that is a defined data communication standard, into another defined network protocol, that is to say another defined data communication standard, according to a permanently implemented set of rules. Such solutions are usually suitable only for specific applications in which the network protocols to be communicated with each other are always the same. A demand-specific change of such translator boxes is only possible by complex re-implementation of a network protocol by this new protocol is programmed.
  • However, the cooperation of different forces or forces requires the ability to react flexibly to new threats or defensive scenarios, which may require combining forces, forces, or even parts of forces, as needed, in order to best perform certain required military tasks to be able to. This requires that these military units always communicate with each other easily and in particular can exchange data.
  • The object of the present invention is therefore to provide a gateway device which makes it possible to flexibly provide data communication connections between subscribers who apply different data communication standards.
  • Furthermore, the present invention is intended to provide a method for the flexible conversion of data of an input data stream present in a first data communication standard into data of an output data stream which are to be present after the conversion in a second data communication standard.
  • PRESENTATION OF THE INVENTION
  • The object directed to the gateway device is achieved by the gateway device having the features of patent claim 1.
  • In the gateway device according to the invention for the intercommunicative data transmission connection of hardware components that are integrated or can be integrated in different data communication networks, wherein different data communication standards are used in the different data communication networks, the gateway device is designed to be of to convert incoming data information corresponding to a first external data communication standard into a gateway proprietary data communication standard and to transfer the data information from the gateway proprietary data communication standard into another external data communication standard and then send the thus converted data information to a second hardware component according to the further external data communication standard.
  • ADVANTAGES
  • The interposition of the Gateway proprietary data communication standard makes it possible, while minimizing the rules to be governed by the gateway for the conversion of the Data information from the one external data communication standard in the other external data communication standard to maximize the controllable by the gateway conversion options. Namely, for each external data communication standard, only one set of rules has to be provided, namely the set of rules for the conversion between the respective external data communication standard and the gateway-proprietary data communication standard. This n: 1 relationship provided by the invention contrasts with an n: n relationship that would have to be provided without interposing the gateway proprietary data communication standard, which would dramatically increase the number of policies required.
  • Furthermore, the solution according to the invention makes it possible to quickly, easily and inexpensively implement a new external data communication standard in the gateway, since only the rules for the conversion between this new external data communication standard and the gateway-proprietary data communication standard are created and implemented got to. The gateway then immediately controls the conversions between the new external data communication standard and all other external data communication standards already governed by the gateway.
  • Further preferred and advantageous design features of the gateway device according to the invention are the subject of the dependent claims 2 to 7.
  • Preferably, the gateway component comprises a memory device (12) or is connectable or connectable to a memory device (12) storing conversion information for conversion between the gateway proprietary data communication standard and at least one external data communication standard. Storing the conversion information in a memory device provides a flexible system in which new conversion information can be quickly added for other data communication standards.
  • It is also advantageous if the conversion information for the conversion between the gateway-proprietary data communication standard and a respective external data communication standard is stored or storable in the memory device as a set of rules data. This standardization of the conversion information in a policy set increases the flexibility of the gateway facility and speeds the addition of new conversion information for other data communication standards.
  • Preferably, the hardware components included in data communication networks are themselves interconnected elements of hardware structures that are part of the parent data communication network. Preferably, the hardware components are sensors or weapon control computers of military equipment.
  • In a particularly advantageous embodiment of the invention, the gateway device is formed by a computer having a computer unit, at least one data communication input, at least one data communication output and at least one memory device. This computer may be a stand-alone hardware (gateway computer) of a hardware gateway device. However, the gateway can also be formed by at least one other available computer in one (or more) of the data communication networks to be interconnected, which then, if a corresponding gateway software runs on it, performs the function of the gateway device and forms a gateway computer.
  • Thus, either a central gateway device with an integrated gateway computer can be provided between the data communication networks to be connected to one another, or at least one decentralized gateway device can be provided which has an already existing gateway gateway or a gateway gateway that is already provided for the conversion tasks. Computer uses. For example, a gateway computer may be provided as a decentralized gateway device according to the invention in each of the communicating data communication networks.
  • In a computer unit of such a gateway computer preferably a computer program is stored executable, which by means of a stored in the memory device first set of rules from an input from the first hardware component through the data communication input input data stream, in a first external data communication Standard, data extracted, this extracted data is converted into a data stream of a gateway-proprietary data communication standard, the data in the gateway proprietary data communication standard data stream by means of a second set of rules stored in the storage device into a data stream of a second external Data communication standards and converts the thus obtained converted Data stream through the data communication output for forwarding to the second hardware component outputs. The hardware components can be directly connected to the gateway or communicate with each other via at least one network via the gateway device.
  • The directed to the method part of the object is achieved with the steps of the method according to claim 8.
  • This inventive method for converting data of an input data stream present in a first data communication standard into data of an output data stream which are to be present after the conversion in a second data communication standard for the purpose of establishing an intercommunicating data transmission connection comprises Steps:
    • a) receiving an input data stream supplied by a data communication input and present in a first external data communication standard;
    • b) analyzing and recognizing the first external data communication standard and determining and loading a first policy record stored in the memory device;
    • c) converting the data information present in the first external data communication standard into data information of a gateway-proprietary data communication standard;
    • d) converting the data information present in the proprietary data communication standard by means of a second set of rules data loaded from the memory device into data information of a second external data communication standard and
    • e) outputting the thus obtained converted data stream through the data communication output for forwarding to a second hardware component.
  • With this method, the advantages already stated in relation to the device according to the invention are achieved.
  • In this case, the steps a) to e) are preferably carried out in real time, which leads to a highly efficient conversion method.
  • Finally, the invention is still directed to a computer program product which is designed to execute the steps of the method according to the invention on a computer device.
  • Preferred embodiments of the invention with additional design details and other advantages are described and explained in more detail below with reference to the accompanying drawings.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • It shows:
  • 1 a schematic representation of a data communication network with a connected gateway device;
  • 2 two interconnected via a gateway device, schematically illustrated data communication networks and
  • 3 a flow chart of a conversion method according to the invention.
  • PRESENTATION OF PREFERRED EMBODIMENTS
  • In 1 is schematically a data communication network 1 shown, which is drawn here by way of example only as a ring, but may also have any other suitable network topology.
  • With this data communication network 1 are a variety of communication partners 10 . 11 . 12 . 13 . 14 . 15 . 16 , in turn, hardware components 10 ' . 11 ' . 12 ' . 13 ' . 14 ' . 15 ' . 16 ' which participate in the data communication, for example, connected via a respective data radio link. These hardware components may be, for example, sensors, actuators, active systems, on-board computers, weapon control computers or command centers, and either directly in communication with the data communications network 1 or with the interposition of one or more further networks via the data communication network 1 communicate. For example, a weapons control computer 11 ' of the armed helicopter 11 directly via radio data transmission with the data communication network 1 keep in touch. Also a radar sensor 13 ' an air surveillance plane 13 or one of the sensor signals of another air monitoring aircraft 14 evaluating computer 14 ' can each as a hardware component directly to the data communication network 1 communicate and communicate with each other.
  • When speaking of hardware components, this implies that this hardware component may also comprise a computer or may be constituted by a computer, and the data to be exchanged therefrom or for this hardware component may be generated in the computer by software running therein or be further processed.
  • The example of in 1 represented ships 10 . 12 . 15 . 16 can be explained that the corresponding hardware components of these ships, such as sonar devices 10 ' , Ship radars 12 ' , Target acquisition and tracking devices 15 ' or weapon system computer 16 ' , are first integrated into an on-board data communication network of the respective ship and then via a network communication computer with the data communication network 1 keep in touch. All the aforesaid in the data communications network 1 integrated hardware components 10 ' . 11 ' . 12 ' . 13 ' . 14 ' . 15 ' . 16 ' communicate over the data communications network 1 together in a first data communication standard so that they can exchange data with each other.
  • In 1 is still a submarine 17 to recognize the hardware components 17 ' For example, they are only able to communicate in a second, different from the first data communication standard. For example, this second data communication standard may be an older standard because the submarine is an older submarine or because the submarine is part of the armed forces of another state. The hardware components 17 ' this submarine 17 are therefore not suitable per se, in the data communication network 1 to be involved.
  • Into the data communication path between the hardware components 17 ' of the submarine 17 and the data communication network 1 is a gateway facility 2 provided, which is designed according to the invention to one of the hardware components 17 ' of the submarine 17 incoming data information, which is written in the second data communication standard, to convert it as data information according to the first data communication standard to the data communication network 1 is forwarded. In the same way, the gateway facility 2 Data information transmitted in the opposite direction from that from the data communication network 1 convert the first data communication standard into the second data communication standard and to the hardware components 17 ' of the submarine 17 hand off. The conversion of the data information between the different data communication standards is done in real time, that is "on the fly", without the data in the gateway device 2 must be cached, and thus virtually without delay.
  • The gateway facility 2 does not have to, as in 1 is shown schematically, be provided as an independent hardware device between the hardware components communicating with each other, but it can, for example, from the hardware components provided in the submarine 17 ' or a computer associated with them, wherein on the computer a corresponding conversion software according to the invention runs as gateway software and makes this computer to a gateway computer and thus to the gateway device. In this way, for example, older hardware components can be quickly and easily adapted by a software upgrade to a new data communication standard, without the need for profound changes to the hardware component must be made.
  • In 2 Another example application of a gateway device according to the invention is shown in which two different data communication networks 3 . 4 in each of which is communicated with a different data communication standard, communicatively via a gateway device 5 connected to each other. Again, the gateway device converts 5 incoming data information of one data communication standard in data information of the other data communication standard "on the fly" in both directions.
  • The gateway facility 5 can, as in 2 is shown schematically, for example as a relay station between the two data communication networks 3 . 4 It can also be arranged as a hardware component in one of the networks 3 . 4 or in each of the two networks 3 . 4 or may run as gateway software in a network management computer of one of the networks or in network management computers of both networks.
  • Such an interconnection of networks 3 . 4 Of course, this is not limited to two networks. Also, the invention is not limited to the described military applications, but it is suitable for any application in which data communication must be done with data information, which is present in different data communication standards and the hardware components or associated software involved, for the transmission and reception of data in each other data communication standards are formed.
  • 3 shows schematically using a flow chart how according to the inventive method incoming in a first external data communication standard data information from the gateway device according to the invention with the interposition of a gateway-proprietary data communication standards in a second external data communication standard corresponding data information is converted.
  • First, in step a), the incoming data in the first external data communication standard is received as received from the first hardware component input data stream via the data communication input E of the gateway device G.
  • Then the first external data communication standard in step b1), for example by means of stored recognition parameters, is analyzed and recognized and the set of rules for this recognized first external data communication standard becomes the appropriate set of rules for converting this first external data communication standard into the gateway proprietary data communication standard certainly.
  • The set of regulations R1 belonging to this specific set of rules is loaded from a storage device S into a main memory in a next step b2). Subsequently, the data stream data in step c) are converted to the gateway proprietary data communication standard.
  • In a following step d1) another set of rules R2 is loaded into the main memory which contains the rules for the conversion between the gateway proprietary data communication standard and the second external (target) data communication standard loaded into the main memory. Then, the data information from the data stream present in the gateway proprietary data communication standard is converted to the destination data communication standard in step d2).
  • This converted data stream is finally output in step e) by the data communication output A for forwarding to the second hardware component.
  • For reverse conversion, the process is run in the same way, with only the policy records R1, R2 applied in reverse order.
  • In this way, the bidirectional conversion of the data streams between different data communication standards "on the fly" quickly and reliably, even if briefly successively data streams must be converted, which correspond to different data communication standards, what then possibly another set of rules R3 or several other policy records are used.
  • Due to the automatic detection of the incoming data communication standard and the rapid availability of the associated rules in the memory device S, the gateway device G can work quickly and flexibly. If a new data communication standard needs to be added, all that is required is to create a new policy record describing the conversion between this new data communication standard and the Gateway proprietary data communication standard and this new policy record in the storage device S store. The gateway device is then immediately able to make conversions for this new data communication standard.
  • It can therefore be waived to provide a myriad of conversion rules, each containing the rules for the conversion of an external data communication standard in another external data communication standard, because the inventively provided intermediate conversion in the gateway proprietary data communication standard creates a standardization that results in less storage space needed to store the policies. Also, the gateway device according to the invention is much faster and more flexible adaptable to new data communication standards.
  • Reference signs in the claims, the description and the drawings are only for the better understanding of the invention and are not intended to limit the scope.
