Definitions
- the invention relates to a method for controlling data transmission, a system for carrying out the method, a computer program product and a computer-readable medium.
- Different types of resources are required for the transmission of data.
- hardware resources such as computing power, storage space and/or a number of accessible communication channels are required.
- different software resources may be required to implement the data transmission.
- Such software resources are usually services, such as services for the purpose of a file transfer or a transmission of process data from a communication participant. These services enable data transmission using predetermined protocols at various levels of the OS I standard model.
- the resources required for data transmission have been adapted as a function of a need for a data quantity and/or data type to be transmitted. This is usually done by booking additional resource capacities from a cloud provider. With a very high volume of data to be transmitted within a short period of time, this can lead to high costs.
- the object of the invention is to specify an improved method for controlling data transmission.
- the invention is based on the object of specifying a system for carrying out the method according to the invention.
- the invention is based on the objects of specifying a computer program for carrying out the method and a computer-readable medium.
- the method according to the invention is a method for controlling a data transmission between a communication participant of the first type and a plurality of communication participants of the second type. At least one load parameter relating to the data transmission is recorded in order to control the data transmission. A comparison value is determined on the basis of the at least one load parameter. Furthermore, this comparison value is compared with a predefinable limit value. As soon as the comparison value is greater than the predefinable limit value, the data transmission between the communication subscriber of the first type and at least one of the multiple communication subscribers of the second type is restricted or interrupted. In this case, the load parameter represents utilization of an existing capacity of one or more resources that are required for the purpose of data transmission.
- resources are in particular the aforementioned resources, such as a hardware resource or a software resource.
- a hardware resource is, for example, computing power, memory or a number of communication channels.
- Examples of a software resource are services that serve the purpose of data transmission, such as telemetry services, file transfer services or localization services.
- the method according to the invention makes it possible to adapt a data volume to be transmitted to a limited resource in a simple manner.
- An advantageous embodiment variant provides that, for the purpose of restricting or interrupting the data transmission, this frequency is reduced in the case of transmission of data that is regularly transmitted at a predetermined frequency. In this way, a simple reduction in the data volume flow can be made possible.
- At least one of the multiple second-type communication participants is selected according to at least one selection criterion. This enables a specific selection of a communication participant of the second type, for whom at least partial communication silence can be provided.
- An advantageous embodiment variant provides that a selection criterion of the first type is used as the at least one selection criterion, after which at least one of the multiple communication users of the second type is selected depending on the level of its contribution to the load parameter. On in this way, a limitation of data traffic can be achieved that is economical in terms of outlay.
- An advantageous embodiment provides that according to the selection criterion of the first type, at least one of the plurality of second-type communication users is selected whose contribution to the load parameter is the highest. In this way, the method for controlling the data transmission can be optimized.
- a further advantageous embodiment variant provides that the amount of the contribution to the load parameter is based on the use of computing power, memory space, a number of communication channels used and/or a number of for the purpose of carrying out the data transmission by the at least one communication participant services of the second type for the purpose of data transmission. In this way, a flexibly adaptable control method can be implemented.
- an advantageous embodiment variant provides that a relevance is assigned to each of the multiple communication participants of the second type.
- a selection criterion of the second type be used as the at least one selection criterion, after which the at least one communication participant of the second type is selected depending on the relevance assigned to it.
- the relevance of a communication participant of the second type can be based on a task assigned to it.
- Such a task can be, for example, a safety-related task, a rescue-related task, a transport task or taking a break. Consequently, such a relevance can be assigned to a communication participant of the second type in absolute terms or linked to a schedule and/or an event plan. Examples of a time and/or event plan is, for example, a timetable or a maintenance plan.
- An advantageous embodiment provides that those communication participants of the second type, which are assigned a low relevance, are preferably used or selected for the purpose of interrupting or restricting the data transmission.
- an advantageous embodiment provides that, in the event that data is to be transmitted by means of a communication participant of the second type, to which a high relevance is assigned, data transmission by another communication participant of the second type, to which a low relevance is assigned, is restricted or is interrupted. In this way it can be ensured that relevant data is transmitted preferentially. In addition , this makes it possible to dispense with exception regulations or extensive exceedances of the specified limit value in the event of a transmission of relevant data .
- a relevance is assigned to the data to be transmitted.
- a selection criterion of the third type is used as the at least one selection criterion, according to which the at least one communication participant of the second type is selected depending on a relevance of the data to be transmitted by him.
- a relevance relating to such data can be based, for example, on a type, age, size, type and/or frequency of the intended transmission of the data or similar parameters of data.
- the third type of selection criterion is preferably used to select that communication participant of the second type, by means of which transmission of data with little relevance is provided.
- a transmission of data with low relevance is restricted or interrupted according to the selection criterion of the third type.
- data that has been assigned a higher relevance has priority over data that has been assigned a lower relevance.
- highly relevant data can be transmitted.
- a transmission of data with less relevance can be postponed until a resource utilization allows a transmission of this data relevance.
- the communication participant of the first type transmits an instruction for the purpose of restricting or interrupting the data transmission to the at least one communication participant of the second type selected in the manner mentioned above as soon as the comparison value is greater than the predefinable limit value.
- This makes it possible to order at least partial silence in communication. In particular, this can be called out easily and reliably by the first type of communication user as a central location to individually selected second type communication users.
- the instruction for the purpose of restricting or interrupting the data transfer is transmitted from at least one of the several second-type communication participants to the first-type communication participant.
- a further advantageous development provides that the data transmission between the first type of communication participant and at least one of the plurality of second type communication participants is restricted or interrupted until the comparison value is less than the predefinable limit value.
- existing resources can be conveniently protected from overloading.
- failures caused by overload or scaling due to an increased need for resources can be easily prevented in this way.
- An advantageous embodiment provides that a restriction or interruption of said data transmission between the first type of communication user and at least one of the second type of communication user is at least partially lifted as soon as the comparison value is less than a threshold value. This always happens to such an extent that the comparison value is smaller than the aforementioned predefinable limit value.
- the available resources can be optimally used in this way.
- Said threshold value is preferably always smaller than the predefinable limit value or equal to the threshold value. It is conceivable that briefly exceeding the limit value will be tolerated. For example, data with high relevance can be transmitted in this way without making extensive interruptions or restrictions on other data or communication participants of the second type.
- a further advantageous embodiment provides that, in addition to restricting or interrupting the data transmission due to the fact that the comparison value is greater than the definable limit value, the data transmission between the communication participant of the first type and at least one of the several communication participants of the second type is restricted due to a predetermined event or is interrupted.
- a predetermined event can be, for example, a predetermined point in time, a schedule, maintenance, an update, a foreseeable restart of one or more services and/or another foreseeable activity linked to a point in time.
- the method according to the invention can be carried out by means of the system according to the invention.
- the system according to the invention has a communication participant of the first type and several communication participants of the second type.
- the communication participant of the first type and the plurality of communication participants of the second type are connected to one another by means of a network.
- the communication participant of the first type and the plurality of communication participants of the second type are preferably connected to one another by means of the network for the purpose of data transmission.
- the system is set up to carry out the method according to the invention. In this way, an operationally safe and reliable system can be provided.
- the first type of communication participant is in the form of a stationary communication participant.
- the multiple communication participants of the second type are each designed as mobile communication participants.
- the mobile communication participants are preferably in the form of vehicles. These vehicles are particularly preferably designed as rail vehicles.
- an advantageous development of the system provides that the multiple switching devices of the communication subscriber of the second type are set up to transmit data between a local network and a mobile radio network. In this way, the effects of poor reception from a switching device on a transmission of data can be compensated for by good reception from other switching devices. Such a difference between the reception of a switching device and other rental devices can arise, for example, through the use of different network providers.
- the invention also provides a computer program. When the computer program according to the invention is executed, the system according to the invention is prompted to carry out the method according to the invention.
- the invention provides a computer-readable medium, which has instructions by means of which the system according to the invention is prompted to carry out the method according to the invention.
- the computer-readable medium can be, for example, a CD-ROM, a DVD, a USB or flash memory or an intangible medium such as a data stream and/or a data carrier signal.
