Description
System and method of data generation, transferring, storing and restoration
Technical Field
The invention relates to the field of information systems and technologies and can be used in database management systems, server network architecture, cryptocurrencies, the financial and banking sectors' information systems, objects and processes automatic control systems, etc.
Background Art
Known centralized systems and methods of generating and storing data that contain peripheral nodes in which data is generated and stored, which are transmitted via communication lines to a central node for storing [1].
However due to the physical loss of the central node and at least one of the peripheral nodes and (or) the data they contain, the integrity of the data stored in the system at the time of loss will be lost.
There are known distributed systems and methods for generating and storing data containing nodes in which data is generated and stored, which can be transmitted via communication lines to one or more other nodes [1, 2]. With a high level of replication of data generated in each node to other nodes via communication lines, it is possible to achieve a high level of stability of the data generation and storage system to the loss of the holistic body of data available in the system with physical loss of one or more nodes and / or data contained in them.
However, such systems and methods have two significant disadvantages:
1. The high level of data replication in a distributed system significantly increases the risk of unauthorized access to holistic body of data in the data generation and storing system;
2. High level of data replication in a distributed data generation and storing system and cryptographic algorithms (e.g. blockchain [2]) aimed at the data reliability (authenticity) ensuring are very energy consuming [3].
Disclosure of Invention
The invention object is to provide a stability high level of the system and method of generation, transferring, storing and restoration data to data loss, including possibly the holistic body of data, with data loss at the central and one or more peripheral nodes of the system while reducing:
1. risk of access to data, including possibly the holistic body of data, contained in the data generation, transferring, storing and restoration system, compared to such distributed systems with a high data replication level;
2. level of energy consumption compared to distributed systems and methods of data generation, transferring, storing and restoration with a high data replication level.
The problem is solved by the fact that in the system of data generation, transferring, storing and restoration containing peripheral nodes, made with the possibility of data generation and storing and their subsequent transferring via communication lines to the central node for storing, according to the invention, each of the peripheral nodes is additionally connected to each other peripheral node by communication lines, the communication lines providing the ability to transferring data generated in each of the peripheral nodes for storage on one or more other peripheral nodes and the ability to transfer data to one of the peripheral nodes for the data restoration on it in case of the central node loss.
According to the invention, the central node is configured to generate and store the data generated by it and transferring via communication lines to one or more peripheral nodes for storage.
Also, several peripheral nodes are made with the possibility of transferring and storing the data generated in other nodes in order to restore data in case of the central node loss.
One or more peripheral nodes can be made with the ability to transferring and store the data generated in all other nodes and restore the holistic body of data in case of the central node loss.
This problem is also solved by the fact that the method of data generation, transferring, storing and restoration, which includes data generation and storing in the system peripheral nodes in which this data is generated, and data transferring from each peripheral node to the central node via communication lines, assumes, according to the invention, the connection of each peripheral node to each other peripheral node by communication lines, and the data generated in each of the peripheral nodes is additionally transferred via communication lines for storing on one or more other peripheral nodes and, in case of the central node loss, data transferring to one of the peripheral nodes, made with the possibility of transferring and storing the data generated in other nodes.
The central node generates and stores the data generated by it and transfers them via communication lines to one or more peripheral nodes.
According to the invention, the data generated in the nodes is transferred and stored on other several peripheral nodes in order to restore data in case of the central node loss.
In case of the central node and one or more peripheral nodes loss, the system of data generation, transferring and storing shall be restored, in which
one of the peripheral surviving nodes is converted into a central node by restoring system data on it.
According to the invention, the data generated in all other nodes is transferred and stored to one or more peripheral nodes and the data is restored, including possibly the holistic volume of data restoration, in case of the central node loss.
Thus, in addition to all peripheral nodes connection to the central node by communication lines, each peripheral node is connected to each other peripheral node by communication lines, so that the data generated in each of the peripheral nodes is simultaneously transferred via communication lines for storage both on the central node and on one or more other peripheral nodes so that in case of complete loss of data stored on the central node and one or more peripheral nodes, including possibly the holistic body of data, the losses available in the system could be restored with a limited number of data copies in the nodes of data generation, transfer, storing and restoration system.
The technical result of the invention is that the peripheral nodes connection with all other peripheral nodes via communication lines, while simultaneous connection of all peripheral nodes with the central node communication lines allows to ensure the data reproducibility available in the data generation, transferring, storing and restoration system in case of complete data loss on the central node and one or more peripheral nodes with a limited number of data copies generated in each of the nodes.
The invention technical result is also that proposed method of data generation, transferring, storing and restoration provides in case of simultaneous data loss on the central node and one or more system peripheral nodes, or even physical loss of the central node and one or more peripheral nodes in the system, the ability to restore data, including possibly the holistic body of data, that was generated at the time of loss. The presence of data, including possibly the holistic
body of data, allows system restoration to initial state, before the loss of nodes, or a new system structure creation in which one of the peripheral nodes will receive data available in the system, i.e. become the central node. Moreover, the invention technical result is achieved with a limited copies number in each of the peripheral nodes of the data generation, transferring, storing and restoration system.
Thus, proposed system and method of data generation, transfer and storing meets the invention "novelty” criterion as they provide data restoration, including possibly holistic body of data, in case of simultaneous data loss at the central node and one or more system peripheral nodes.
Schematic diagram of data generation, transferring, storing and restoration is shown in figure 1.
Modes for Carrying Out the Invention
The data generation, transferring, storing and restoration contains a central node (1) and an arbitrary number of peripheral nodes (2), (3), (4), (5), ..., (n), where n is total number of system nodes (including the central node and all peripheral nodes). The central node (1) is connected to the peripheral nodes (2), (3), (4), (5), ..., (n) by communication lines (1-2), (1-3), (1-4), (1-5), ..., (1-n) respectively. Each of the peripheral nodes is connected to each other peripheral node by communication lines. For example, node (2) is connected to other peripheral nodes (3), (4), (5), ..., (n) by communication lines (2-3), (2-4), (2- 5), ..., (2-n) respectively. Communication lines (3-4), (3-5), ..., (3-n) connect the peripheral node (3) with the peripheral nodes (4), (5), ..., («) respectively. The communication line (5-n) connects the peripheral nodes (5) and (n).
In each of the peripheral nodes (2), (3), (4), (5), ..., (n), the bodies of data generated in them are stored at each time t, which are denoted by
I2, I3, I4, I5, In- The bodies of dataI2, I3, I4, I5, In can be generated in different ways - automatic computational algorithms entered by the operator, coming from external sources of data sources generation, transferring, storing and restoration, such as sensors, combined paths, etc. At any moment of time t, in the central node (1), it can be stored the holistic body of data of system
Some bodies of data
are also stored on one or several other peripheral nodes, in addition to the central node.
The method of data generation, transferring, storing and restoration is as follows. Bodies of data
which were generated in nodes (2), (3), (4), (5), ..., (n), are simultaneously transferred via communication lines (1-2), (1-3), (1-4), (1-5), ..., (l-«) to the central node (1) and one or more peripheral nodes, so that the total number of the holistic body of data copies q is equal to q = 2 + k, where k is the number of other peripheral nodes to which each of the peripheral nodes transmits data.
For example, consider a situation where k = 2, i.e. each peripheral node stores the data generated and transfers them to two neighbouring peripheral nodes. Then, in the regular mode, the data
generated on the node (2) via communication line (2-n) is transferred to the node («), and via communication line (2-3) - to the node (3), as well as via communication line (1-2) - to the central node (1). Similarly, data generated on node (3) via communication
lines (2-3), (1-3), (3-4) are transferred for storage to nodes (2), (1), (4), respectively. data generated on node (4) via communication lines (4-5), (1-4),
(3-4) are transmitted for storage to nodes (5), (1), (3), respectively. data
generated on node (5) via communication lines (5-n), (1-5), (4-5) are transferred for storage to nodes (n), (1), (4), respectively. data generated on node (n) via
communication lines (5-n), (1-n), (2-n ) is transferred for storage to nodes (5), (1), (2), respectively.
Assume that data transferring via communication lines is much faster than data generation in system nodes, then at each time t we have four copies of the bodies of data
and the holistic body of data
is only at the central node (1).
In the regular mode of operation system generation, the data lines transferring, storing and restoration (2-5), (2-4), (3-5), (3-n), (4-n) remain redundant.
In case of the data loss in the central node (1) and one or more peripheral nodes, the system includes backup communication lines in order to restore data on one of the surviving nodes, possibly the holistic body of data
available in the data generation and storing system in the moment of the nodes loss.
Assume that the system of data generation, transferring, storing and restoration of the holistic body of data has lost all the data available in the nodes (1), (4), (5), (2), for example, due to the physical destruction of these nodes. Then, the node (3) will remain in the system where data is stored in amounts
and node (n) where the data is stored in amounts
Thus, damaged
generation, transferring, storing and restoration system can recover data on one of the remaining nodes, for example, to form the holistic body of data available at the time of nodes loss (1), (4), (5), (2).
For example, via communication line (3-n) to the node (n) bodies of data
and will be transferred from the node (3), so that there will be a holistic data volume in the node (n) available at the moment of
nodes loss (1), (4), (5), (2).
In future, the structure of data generation, transferring, storing and restoration system can be restored to its initial state before the nodes loss, a new system can be formed according to proposed scheme in which one of the peripheral surviving nodes becomes central in new system of data generation, transferring, storing and restoration, etc. The main thing here is that even with
data loss from the central node and a significant number of peripheral nodes, the data, in particular their holistic volume, available in the system at the time of loss will not be lost. Moreover, this is achieved with a limited number of copies of data in each of the peripheral nodes in data transferring, storing and restoration system.
Thus, proposed system and method of data generation, transferring, storing and restoration reduces the risk of access to data it contains, and reduces energy consumption compared to distributed data transferring, storing and restoration systems with a high level of data replication, due to less the number of data replications. At the same time, a high level of proposed system resilience related to data generation, transferring, storing and restoration, including their holistic volume, in case of data loss at the central and one or more peripheral nodes for one reason or another, such as physical destruction of these nodes.
In case of the central node loss (1) and 1 or more other peripheral nodes, the system and method of data generation, transferring, storing and restoration works similarly.
The system operation scheme and principle as well as method of data generation, transferring, storing and restoration were considered on the example when the number of system nodes n = 6. However, the system and method of data generation, transferring, storing and restoration work similarly with any number of nodes n.
The Central node (1) can also generate and store generated data in the volume denoted by with simultaneous transferring to one or more peripheral
nodes via communication lines. Otherwise, the system and method of data generation, transferring, storing and restoration is composed and operate similarly to the above.
