Description

Technical Field

[0001] The present invention relates to the technical field of communication networks, and particularly relates to a multi-device networking system and method based on quantum communication. Background Art

[0002] Quantum communication is a new type of communication method that uses quantum entanglement effects to transmit information. It has ultra-high security, and any eavesdropping behavior will be detected. It can achieve long-distance quantum key distribution to ensure encrypted information transmission. It has broad application prospects in fields with high security requirements such as finance and government affairs.

[0003] A quantum communication networking method based on a multi-wavelength entangled light source is disclosed in the invention patent with the application number 202010199937.1. The method is characterized in that it consists of realizing a multi-wavelength entangled light source, configuring an entangled single-photon wavelength channel, and multi-user arbitrary interconnected quantum communication networking; the realization of the multi-wavelength entangled light source uses the multi-wavelength entangled light source to realize the output of entangled single photons with equal frequency intervals and pairwise entanglement; the configuration of the entangled single-photon wavelength channel constructs a quantum network server and configures the wavelength channel for the entangled single photons; the multi-user arbitrary interconnected quantum communication networking provides entangled single-photon services for multi-user arbitrary interconnection and constructs a quantum communication network; the multi-wavelength entangled light source is realized by the entanglement of two multi-wavelength single-photon sequences or by the spontaneous nonlinear effect. Among them, the realization by the spontaneous nonlinear effect is through a nonlinear resonator represented by a silicon-based micro-ring cavity, concentrating the nonlinear gain within a certain bandwidth near the resonance frequency, and simultaneously having the functions of enhancing the nonlinear effect and multi-wavelength narrowband filtering to realize the output of high-brightness multi-wavelength entangled single photons.

[0004] This application aims to solve the problems of: "(1) A multi-user arbitrary interconnected quantum communication network constructed based on a point-to-point quantum communication system: Both communication parties need to be equipped with separate quantum communication devices, facing huge resource overhead; although the trusted nodes at the service layer can effectively expand the parallel working ability of the two-terminal quantum communication devices, they partially lose the inherent security attributes of quantum communication at the same time; (2) A multi-group user quantum communication network constructed based on a point-to-multi quantum communication system: Users need to be divided into multiple user groups, allowing multiple users within the same group to share the same quantum device and quantum channel, but not supporting quantum communication interconnection between group members; (3) A quantum relay communication network: mainly based on quantum storage technology, quantum entanglement swapping extension technology, and quantum state routing technology. However, there has been no good solution to the problem of long-term storage of quantum states; (4) A quantum communication network based on a high-dimensional quantum communication protocol: It can provide quantum communication services for multiple users. Each user shares the same Hilbert space and independently generates quantum state information within the subspace it occupies; however, adding or deleting users requires an overall modification of the Hilbert space, seriously affecting the flexible adjustability and efficient working ability of the quantum communication network."

[0005] In the case of quantum communication, it can serve a large number of communication user groups at the same time. This results in the disorder of most nodes in its communication network when performing multiple communication data transmission tasks. It can only perform priority transmission according to the intervention time of communication requests, resulting in more computing power consumption during the execution of such operations and affecting the subsequent communication interaction ability of the communication network.

[0006] Therefore, a multi-device networking system and method based on quantum communication are proposed. Summary of the Invention

[0007] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a multi-device networking system and method based on quantum communication, which solves the technical problems proposed in the above background technology.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0009] In a first aspect, a multi-device networking system based on quantum communication includes:

[0010] A creation module, configured to obtain the distribution and association information of communication nodes in a communication network, and create a communication network topology by applying the distribution and association information of communication nodes in the communication network; a monitoring module, configured to monitor the communication scenarios and communication data of each communication node in the communication network in real time; an identification module, configured to receive the communication network topology created by the creation module and the communication scenarios monitored by the monitoring module, and identify a common communication path in the communication network topology based on the communication scenarios; a capture module, configured to obtain the common communication path identified by the identification module, capture the starting end of the common communication path, and perform queue processing on the communication data transmitted by the common communication path; a control module, configured to receive the result of the communication data queue processing by the capture module, and control the communication nodes in the common communication path to continuously transmit the communication data in sequence based on the communication data queue; a message module, configured to collect historical relevant information when the common communication path executes a communication data transmission task, and generate a common communication path operation message based on the historical and relevant information.

[0011] Furthermore, the creation module is provided with sub-modules, including:

[0012] An upload unit, configured to upload the location information of communication nodes in the communication network and the association information of each node;

[0013] A modification unit, configured to receive the communication network topology created by the creation module, and store and modify the communication network topology;

[0014] Among them, the location information of communication nodes in the communication network uploaded by the upload unit is the communication node distribution information, and the association information of each communication node is the location information of another group of communication nodes connected to the communication node. The creation module determines the corresponding positions of the location information of each communication node in the same three-dimensional coordinate system based on the location information of the communication nodes in the communication network and its association information and connects them to each other to create a communication network topology. The communication network topology is a graph composed of points and lines. The modification operations performed by the modification unit on the communication network topology include: deleting and adding points and lines in the communication network topology.

[0015] Furthermore, the monitoring module performs monitoring operations on the communication scenarios and communication data of each communication node in the communication network based on a specified operating cycle. The communication scenario monitored by the monitoring module is the communication node where the communication user is located, that is, the communication node where the communication target user is located. The initial operating cycle applied by the monitoring module is user-defined by the system-side user and satisfies:

[0016]

[0017] In the formula: T 1 、T 2 、T 3 、... are the operating cycles used for the first, second, third,... runs of the monitoring module; t is a user-defined parameter; T 0 is the initial operating cycle; min(T) is the minimum operating cycle; n is the set of operating cycles; T i is the duration of the i-th operating cycle; g(T 1 ∩ T 2 ) is the intersection of the communication users corresponding to each operating cycle in the set n of operating cycles;

[0018] Among them, represents the averaging of . When calculating T 3 、T 4 、..., when taking values, g(T 1 ∩ T 2 ) does not consider the case where the value is equal to zero. When the value of g(T 1 ∩ T 2 ) is equal to zero, the operating cycle value obtained corresponding to T 3 is T 0 . The calculation logic of T 4 、... is the same as that of T 3 .

[0019] Further, during the operation of the monitoring module based on the set operation cycle, the monitoring module synchronously monitors the operation status of the modification unit of the subordinate sub-module of the creation module. When it is detected that the modification unit modifies the communication network topology, the monitoring module resets its operation. After the current operation cycle ends, the monitoring module resumes to T in the next operation cycle. 0 。

[0020] Further, after the recognition module receives the communication network topology and the communication scenario during operation, it identifies the communication path between the node where the communication user is located and the node where the communication target user is located in the communication network topology;

[0021] After the communication path between the node where the communication user is located and the node where the communication target user is located is identified, it further identifies the communication paths with the same node where the communication target user is located among the communication paths;

[0022] After the communication paths with the same node where the communication target user is located among the communication paths are identified, it further identifies the same communication sections in the communication paths;

[0023] Among them, the same communication section in the communication path between the node where the communication user is located and the node where the communication target user is located identified by the recognition module is the common communication path.

[0024] Further, the capture module is internally provided with sub-modules, including:

[0025] A queue unit for traversing the communication data that undergoes packaging processing in the capture module, sorting the communication data to create a communication data queue;

[0026] Among them, during the traversal stage of the queue unit for the communication data, it traverses the time and size of each communication data at the stage of being sent by the communication user, and based on the time and size of the communication data at the stage of being sent, it decides the position of the communication data in the communication data queue:

[0027]

[0028] In the formula: k is the reference value during the sorting of the communication data; Q is the size of the communication data; t start is the time at the stage of the communication data being sent; ω 1 、ω 2 are weights;

[0029] Among them, the larger the reference value k during the sorting of the communication data, the more forward the position of the corresponding communication data in the communication data queue, the sum of the weights ω 1 、ω 2 is 1, and ω 1 >ω 2 ,and ω 1 、ω 2All are positive numbers.

[0030] Furthermore, during the operation stage of the control module, the transmission status of communication data of each node in the common communication path is synchronously monitored. After the previous communication node in the common communication path finishes sending communication data, the next communication node synchronously finishes receiving the communication data sent by the previous communication node. When the next communication node executes the sending of the received communication data, the previous communication node synchronously executes the sending operation of the next communication data in the communication data queue, and so on.

[0031] Among them, during the process of the common communication path transmitting communication data, the capture module runs to generate a new communication data queue and waits for transmission at the starting end of the common communication path.

[0032] Furthermore, the historical relevant information of the common communication path when the message module collects and executes the communication data transmission task includes: the nodes included in the common communication path, the number of common communication paths, the number of times each common communication path is recognized, and the total amount of communication data accumulated and transmitted by each common communication path.

[0033] Furthermore, the lower level of the creation module is connected with an upload unit and a modification unit through wireless network interaction. The creation module is connected with a monitoring module through wireless network interaction. The monitoring module is connected with the modification unit through wireless network interaction. The monitoring module is connected with an identification module and a capture module through wireless network interaction. Inside the capture module, there is a queue unit connected through wireless network interaction. The capture module is connected with a control module and a message module through wireless network interaction.

[0034] In a second aspect, a multi-device networking method based on quantum communication includes:

[0035] Obtain the distribution information and association information of communication nodes in the communication network, and construct a communication network topology based on the distribution information and association information of communication nodes in the communication network; monitor the communication scenarios and communication data of each communication node in the communication network; identify the common communication paths in the communication network topology according to the monitored communication scenarios and communication network topology; obtain the common communication paths, capture the starting ends of the common communication paths, and perform queue processing on the communication data transmitted by the common communication; control the communication nodes in the common communication path to sequentially transmit each communication data in the communication data queue based on the communication data queue; generate a message for the operation of the common communication path and feedback the message to the communication network background management user.

[0036] Adopting the technical solution provided by the present invention, compared with the known public technologies, it has the following beneficial effects:

[0037] The present invention provides a multi-device networking system and method based on quantum communication. During operation, the system accurately constructs a quantum communication network topology, and based on the monitoring of communication scenarios and communication data in the quantum communication network topology, further identifies the common communication paths between communication users. Further, by combining the comprehensive analysis of communication data, a communication data queue is created. Combining the common communication paths with the communication data queue, communication data is transmitted in an orderly manner, and a common communication path operation message is synchronously generated and fed back to the communication network management background user. Based on this, the operation computing power of each communication node in the quantum communication network during the execution of communication tasks is maintained and managed to ensure that the quantum communication network executes daily communication tasks more stably.

[0049] The monitoring module performs monitoring operations on the communication scenarios and communication data of each communication node in the communication network based on a specified operation cycle. The monitored communication scenario is the communication node where the communication user is located, that is, the communication node where the target communication user is located. The initial operation cycle applied by the monitoring module is user-defined by the system-side user and satisfies:

[0050]

[0051] In the formula: T 1 , T 2 , T 3 ,... are the operation cycles used for the first, second, third,... runs of the monitoring module; t is a user-defined parameter; T 0 is the initial operation cycle; min(T) is the minimum operation cycle; n is the set of operation cycles; T i is the duration of the i-th operation cycle; g(T 1 ∩ T 2 ) is the intersection of the communication users corresponding to each operation cycle in the set n of operation cycles;

[0052] Among them, represents the average of . When calculating T 3 , T 4 ,..., when taking g(T 1 ∩ T 2 ), the case where the value is equal to zero is not considered. When the value of g(T 1 ∩ T 2 ) is equal to zero, the operation cycle value obtained corresponding to T 3 is T 0 . The calculation logic of T 4 ,... is the same as that of T 3 ;

[0053] During the operation of the monitoring module based on the set operation cycle, the operation status of the modification unit of the subordinate sub-module of the creation module is synchronously monitored. When it is monitored that the modification unit modifies the communication network topology, the monitoring module resets its operation. After the current operation cycle ends, the next operation cycle resumes to T 0 ;

[0056] A queue unit, configured to traverse the communication data that has undergone packaging processing in the capture module, sort the communication data, and create a communication data queue;

[0057] During the traversal stage when the queue unit traverses the communication data, it traverses the time and size of each communication data at the stage when it is sent by the communication user. Based on the time and size of the communication data at the sending stage, it decides the position of the communication data in the communication data queue:

[0058]

[0059] Where: k is a reference value during the sorting of the communication data; Q is the size of the communication data; t start is the time of the communication data at the stage when it is sent by the communication user; ω 1 、ω 2 are weights;

[0060] Among them, the larger the reference value k during the sorting of the communication data, the more forward the position of the corresponding communication data in the communication data queue. The sum of the weights ω 1 、ω 2 is 1, and ω 1 >ω 2 , and ω 1 、ω 2 are both positive numbers;

[0061] A control module, configured to receive the processing result of the communication data queue in the capture module, and control the communication nodes in the common communication path to continuously and sequentially transmit the communication data based on the communication data queue;

[0062] A message module, configured to collect historical relevant information when the common communication path performs the communication data transmission task, and generate a common communication path operation message based on the historical and relevant information;

[0063] The lower level of the creation module is connected with an upload unit and a modification unit through wireless network interaction. The creation module is connected with a monitoring module through wireless network interaction. The monitoring module is interactively connected with the modification unit through wireless network. The monitoring module is interactively connected with an identification module and a capture module through wireless network. Inside the capture module, there is a queue unit connected through wireless network interaction. The capture module is interactively connected with a control module and a message module through wireless network.

[0064] In this embodiment, the creation module runs to obtain the distribution and association information of communication nodes in the communication network, creates a communication network topology by applying the distribution and association information of communication nodes in the communication network, the upload unit synchronously uploads the location information of communication nodes and the association information of each node in the communication network, the modification unit receives in real time the communication network topology created in the creation module, stores and modifies the communication network topology, the monitoring module runs later to monitor in real time the communication scenarios and communication data of each communication node in the communication network, the recognition module further receives the communication network topology created in the creation module and the communication scenarios monitored in the monitoring module, identifies the common communication paths in the communication network topology based on the communication scenarios, and then the capture module obtains the common communication paths identified in the recognition module, captures the starting end of the common communication paths, and performs queuing processing on the communication data transmitted by the common communication paths. The queuing unit synchronously traverses the communication data that has been packed and processed in the capture module, sorts the communication data to create a communication data queue, and then the control module receives the processing result of the communication data queue in the capture module, controls the communication nodes in the common communication paths to sequentially transmit the communication data continuously based on the communication data queue, and finally the message module collects the historical relevant information when the common communication paths execute the communication data transmission task, and generates a running message for the common communication paths based on the historical and relevant information.

[0065] Based on the system operation in the above embodiment, it provides an effective communication data transmission logic for each communication node in the quantum communication network when performing communication transmission tasks, provides more logical communication computing power management for the communication nodes in the communication network, and ensures that the communication nodes in the quantum communication network can complete the communication data transmission tasks more stably.

[0066] Embodiment 2:

[0067] At the specific implementation level, on the basis of Embodiment 1, this embodiment further specifically describes the multi-device networking system based on quantum communication in Embodiment 1 with reference to Figure 1 as shown:

[0068] The location information of communication nodes in the communication network uploaded by the upload unit is the communication node distribution information, and the association information of each communication node is the location information of another group of communication nodes connected to the communication node. The creation module determines the corresponding positions of the location information representing each communication node in the same three-dimensional coordinate system based on the location information and its association information of the communication nodes in the communication network and connects them to create a communication network topology. The communication network topology is a graph composed of points and lines. The modification operations performed by the modification unit on the communication network topology include deleting and adding points and lines in the communication network topology.

[0069] Through the above settings, the distribution and association information of communication network communication nodes obtained in the creation module are further defined, providing necessary creation data support for the creation of the communication network topology and ensuring the stable completion of the creation operation of the communication network topology.

[0070] As Figure 1 shown, after the recognition module runs and receives the communication network topology and communication scenario, it recognizes the communication path between the node where the communication user is located and the node where the communication target user is located in the communication network topology;

[0071] After the communication path between the node where the communication user is located and the node where the communication target user is located is recognized, the communication paths with the same node where the communication target user is located in each communication path are further recognized;

[0072] After the communication paths with the same node where the communication target user is located in each communication path are recognized, the same communication sections in the communication paths are further recognized;

[0073] Among them, the same communication section in the communication path between the node where the communication user is located and the node where the communication target user is located recognized by the recognition module is the common communication path.

[0074] Through the above settings, a specified recognition logic is provided for the recognition of the common communication path in the system.

[0075] As Figure 1 shown, during the operation stage of the control module, the transmission status of communication data for each node in the common communication path is synchronously monitored, so that after the previous communication node in the common communication path completes the sending of communication data, the next communication node synchronously completes the reception of the communication data sent by the previous communication node. When the next communication node executes the sending of the received communication data, the previous communication node synchronously executes the sending operation of the next communication data in the communication data queue, and so on;

[0076] Among them, during the process of transmitting communication data on the common communication path, the capture module runs to generate a new communication data queue and waits for transmission at the starting end of the common communication path.

[0077] Through the above settings, the logic for executing communication data transmission on the common communication path is further defined to ensure that communication data is transmitted and interacted using the common communication path.

[0078] As Figure 1 shown, the historical relevant information when the common communication path collected in the message module executes the communication data transmission task includes: the nodes included in the common communication path, the number of common communication paths, the number of times each common communication path is recognized, and the total amount of communication data accumulated and transmitted by each common communication path.

[0079] Through the above settings, the historical relevant information during the execution of the communication data transmission task by the common communication path collected in the message module is further defined, providing necessary operation data support for the operation of the system in Embodiment 1.

[0080] Embodiment 3:

[0081] At the specific implementation level, on the basis of Embodiment 1, this embodiment further specifically describes the multi-device networking system based on quantum communication in Embodiment 1 with reference to Figure 2 as shown:

[0087] Control the communication nodes in the common communication path to sequentially transmit each communication data in the communication data queue based on the communication data queue;

[0088] Generate a running message for the common communication path and feedback the message to the communication network background management user.

[0089] Through the above method, further operation logic support is provided for the system in Embodiment 1, ensuring the stable operation of the system in Embodiment 1, and providing a management effect for the allocation of communication data transmission computing power of each communication node in the quantum communication network.

[0090] In summary, the system in the above embodiments accurately constructs a quantum communication network topology during operation, and based on the monitoring of communication scenarios and communication data in the quantum communication network topology, further identifies the common communication path between communication users. Further, through the comprehensive analysis of communication data, a communication data queue is created, and the communication data is orderly transmitted in combination with the common communication path and the communication data queue. At the same time, a running message for the common communication path is generated and fed back to the communication network management background user. Based on this, the operation computing power of each communication node in the quantum communication network during the execution of communication tasks is maintained and managed, ensuring that the quantum communication network more stably executes daily communication tasks.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
