Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0038] In some embodiments, the embodiments of the present application provide a data transmission system that can solve the data transmission problem between a quantum communication network and a communication network.

[0039] In some embodiments, Figure 1 As shown, an embodiment of the present application provides a data transmission system, including an IPv6 node 101, an IPv6 routing device 102, a quantum gateway 103, and a quantum node 104.

[0040] The IPv6 node 101 is configured to send a first data packet including a first IPv6 message to the IPv6 routing device 102, where the first IPv6 message may carry a quantum address of the quantum node 104;

[0041] The IPv6 routing device 102 is used to send the first data packet including the first IPv6 message to the sub-gateway 103;

[0042] The quantum gateway 103 is used to send the first data packet to the quantum node indicated by the quantum address.

[0043] The embodiment of the present application sets up the above-mentioned data transmission system, sends a first data packet including a first IPv6 message to an IPv6 routing device through an IPv6 node, and sends the above-mentioned first data packet including the first IPv6 message to a quantum gateway through an IPv6 node, so that the quantum gateway sends the above-mentioned first data packet to the quantum node indicated by the quantum address based on the quantum address carried by the first IPv6 message, thereby realizing point-to-point transmission of the first data packet from the IPv6 node to the quantum node, and realizing the interconnection between the quantum communication network and the communication network.

[0044] In some embodiments, Figure 2 As shown, the embodiment of the present application provides a data transmission method, which may include the following steps S210-S240:

[0045] S210: The IPv6 node sends a first data packet to an IPv6 routing device, where the first data packet includes a first IPv6 message, and the first IPv6 message may carry a quantum address of the quantum node.

[0046] like Figure 2 As shown, the above-mentioned IPv6 node can send a first data packet to the IPv6 routing device, and the above-mentioned first data packet can include a first IPv6 message. The above-mentioned first IPv6 message can carry a quantum address. Here, in order not to affect the transmission of the first IPv6 message between the IPv6 node and the IPv6 routing device, the above-mentioned quantum address can be set in the extension field of the first IPv6 message.

[0047] S220: The IPv6 routing device sends a first data packet including a first IPv6 message to the vector gateway.

[0048] When receiving the first data packet, the IPv6 routing device may send a first data packet including a first IPv6 message to the sub-gateway.

[0049] S230: The quantum gateway sends a first data packet to the quantum node indicated by the quantum address based on the quantum address.

[0050] The quantum gateway may send the first data packet to the quantum node indicated by the quantum address based on the quantum address. It can be imagined that one quantum address indicates one quantum node, and the quantum address is determined by the quantum gateway when receiving a registration request sent by the quantum node. In some examples, the quantum address may be a quantum state bit stream with a length of 64 bytes.

[0051] In the embodiment of the present application, an IPv6 node sends a first data packet to an IPv6 routing device, and the IPv6 routing device sends the first data packet to a quantum gateway. When the quantum gateway receives the first data packet sent by the IPv6 routing device, it sends the first data packet to the quantum node indicated by the quantum address carried by the first IPv6 message, thereby enabling communication between the IPv6 node and the quantum node, filling the gap in data transmission between the quantum node and the IPv6 node in the prior art.

[0052] In some embodiments, Figure 3 As shown, the above data transmission method may further include the following steps S310-S350:

[0053] S310: The quantum node sends a data packet to the quantum gateway, where the data packet includes a second IPv6 message, and the second IPv6 carries the IPv6 address of the IPv6 node.

[0054] The quantum node can send a data packet to the quantum gateway. The data packet may include a second IPv6 message. The second IPv6 message may carry the IPv6 address of the IPv6 node. Here, the IPv6 address is generated when the quantum node receives the IPv6 address prefix sent by the quantum gateway.

[0055] S320: The quantum gateway determines the quantum address corresponding to the IPv6 address based on the IPv6 address.

[0056] The quantum gateway can query the quantum address corresponding to the IPv6 address from the pre-established correspondence table between the IPv6 address and the quantum address.

[0057] S330: The quantum gateway adds the quantum address to the second IPv6 message based on a preset address adding rule to obtain a third IPv6 message and a second data packet including the third IPv6 message.

[0058] The quantum gateway can add a quantum address corresponding to the IPv6 address in the second IPv6 message based on a preset address adding rule to obtain a third IPv6 message. Here, the quantum address can be added in an extension field of the second IPv6 message.

[0059] S340: The quantum gateway sends a second data packet including a third IPv6 message to the IPv6 routing device.

[0060] S350: The IPv6 routing device sends a second data packet to the IPv6 node indicated by the IPv6 address.

[0061] In the embodiment of the present application, a data packet including a second IPv6 message is sent to a quantum gateway through a quantum node. After determining the quantum address corresponding to the IPv6 address, the quantum gateway can add the quantum address corresponding to the IPv6 address to the second IPv6 message to obtain a third IPv6 message. Then, the quantum gateway sends a second data packet including the third IPv6 message to an IPv6 routing device. Then, the IPv6 routing device sends the second data packet to the IPv6 node indicated by the IPv6 address, thereby realizing data transmission from the quantum node to the IPv6 node. Furthermore, the mapping relationship between the IPv6 address and the quantum node can improve the accuracy of data transmission.

[0062] In some embodiments, the preset address adding rule includes an address adding rule in an extension field of the second IPv6 message header. It is conceivable that the quantum address can be added in the extension field of the second IPv6 message header.

[0063] Here, an extension field may be inserted between the header of the second IPv6 message and the upper layer data, for example, an extension header may be inserted. In some examples, the rule for adding the quantum address may be as shown in the following Table 1:

[0064] Table 1

[0065]

[0066] The embodiment of the present application uses the above-mentioned address addition rules to naturally "embed" the quantum address into the IPv6 message. During the data packet forwarding process, the quantum address can be recognized and processed by the quantum gateway, so that the quantum gateway can extract the quantum address and determine the corresponding IPv6 address based on the quantum address to complete cross-network addressing. As for the IPv6 routing device, since the addition of the quantum address strictly follows the extended header syntax, the IPv6 routing device can regard it as a transparent data payload and does not affect the normal data forwarding logic. The embodiment of the present application cleverly uses the scalability of the message header field of the IPv6 message to achieve data transmission from the quantum node to the IPv6 node based on the above-mentioned changes to the IPv6 message.

[0067] The quantum node can send a request to the quantum gateway to obtain an IPv6 address prefix and generate an IPv6 address based on the IPv6 address prefix.

[0068] In some embodiments, Figure 4 As shown, before the quantum gateway receives the first data packet sent by the IPv6 routing device, the method may further include the following steps S410-S430:

[0069] S410: The quantum node sends a request to the quantum gateway, where the request includes a quantum address.

[0070] Here, the quantum node may send a request to the quantum gateway, the request may include a quantum address, and the request may be a registration request for the quantum node to register with the quantum gateway.

[0071] S420: The quantum gateway stores the quantum address and sends a preset IPv6 address prefix to the quantum node.

[0072] The quantum gateway can store the quantum address and determine the IPv6 address prefix corresponding to the quantum address based on a preset configuration strategy. The preset configuration strategy can be a priority-based configuration strategy, for example, the priority of the quantum node is determined based on factors such as the type and security level of the quantum node, and the IPv6 address prefix corresponding to each quantum node is determined by the priority.

[0073] In some examples, a mapping relationship table between quantum addresses and IPv6 address prefixes may be stored in the quantum gateway, and the mapping relationship table may include the lifetime, that is, the validity period, of the mapping relationship between the quantum address and the IPv6 address prefix, and the priority of the quantum node. Here, one IPv6 address prefix may correspond to multiple quantum addresses. When multiple quantum nodes indicated by multiple quantum addresses transmit data to the quantum gateway, the quantum gateway may determine the data to be processed first based on the priority of the quantum node. The mapping relationship table may be shown in Table 2 below:

[0074] Table 2

[0075]

[0076] S430: The quantum node generates an IPv6 address based on the IPv6 address prefix.

[0077] The quantum node can generate an IPv6 address based on the above IPv6 address prefix, so that subsequent quantum nodes can carry the above IPv6 address when generating IPv6 packets.

[0078] In some embodiments, when the quantum gateway receives an IPv6 message carrying an IPv6 address sent by a quantum node, the IPv6 address can be stored and a correspondence table between the IPv6 address and the quantum address can be established.

[0079] It can be imagined that in order to improve data security, the data packet sent by the above-mentioned quantum node to the quantum gateway can be a data packet encrypted by the quantum node using a preset encryption algorithm.

[0080] In some embodiments, Figure 5 As shown, the request sent by the quantum node to the quantum gateway may also include a request for obtaining an encryption key. Before the quantum gateway sends a preset IPv6 address prefix to the quantum node, the method may also include the following steps S510:

[0081] S510: The quantum gateway generates an encryption key and a decryption key based on the acquisition request, and stores the encryption key and the decryption key.

[0082] It can be imagined that the request sent by the above-mentioned quantum node to the quantum gateway may carry an acquisition request for obtaining an encryption key, and the quantum gateway may generate an encryption key and a decryption key based on the acquisition request, and store the above-mentioned encryption key and decryption key.

[0083] The method of sending a preset IPv6 address prefix to a vector node includes the following steps S520:

[0084] S520: The quantum gateway sends a preset IPv6 address prefix and encryption key to the quantum node.

[0085] The quantum gateway can send the above IPv6 address prefix and encryption key to the quantum node.

[0086] In the embodiment of the present application, a quantum node sends a request to a quantum gateway to obtain an IPv6 address prefix and simultaneously sends an acquisition request to obtain an encryption key, so that the quantum gateway generates an encryption key and a decryption key based on the acquisition request, and sends the IPv6 address prefix and the encryption key to the quantum node, thereby integrating the processes of key negotiation and obtaining the IPv6 address prefix and simplifying communication delays.

[0087] Based on the same inventive concept, an embodiment of the present application provides a data transmission device.

[0093] Based on the IPv6 address, determining a quantum address corresponding to the IPv6 address;

[0094] Based on a preset address adding rule, a quantum address is added to the second IPv6 message to obtain a third IPv6 message and a second data packet including the third IPv6 message, and the second data packet including the third IPv6 message is sent to the IPv6 routing device, so that the IPv6 routing device sends the second data packet to the IPv6 node indicated by the IPv6 address.

[0095] In some embodiments, the preset address adding rule includes an address adding rule in an extension field of the second IPv6 packet header.

[0104] The sending module 701 is used to send a control instruction to the IPv6 routing device, where the control instruction is used to instruct the IPv6 routing device to send the first data packet to the quantum gateway when receiving a first data packet including a first IPv6 message sent by an IPv6 node, so that the quantum gateway sends the first data packet to the quantum node indicated by the quantum address, wherein the first IPv6 message carries the quantum address.

[0105] In some embodiments, the sending module 701 may also be used to:

[0106] An address adding rule is sent to the quantum gateway, so that when the quantum gateway receives a second data packet including a second IPv6 message sent by the quantum node, the quantum gateway adds a quantum address corresponding to the IPv6 address in the second IPv6 message based on the preset address adding rule to obtain a third IPv6 message, and sends the data packet including the third IPv6 message to the IPv6 routing device, so that the IPv6 routing device sends the data packet including the third IPv6 message to the IPv6 node indicated by the IPv6 address.

[0113] The quantum address registration module 902 is used to receive a request sent by a quantum node and send an IPv6 address prefix to a quantum node based on the request.

[0117] In some embodiments, Fig.10 As shown, an embodiment of the present application provides a structural schematic diagram of a control device, and the control device includes:

[0118] The network topology management module 1001 can communicate with the forwarding plane device through the control interface (such as OpenFlow, Netconf, etc.) to discover and maintain the whole network topology view in real time. The controller can obtain the location, connection relationship, capacity attributes and other information of the quantum gateway and IPv6 routing device, and can provide a basis for routing calculation and resource scheduling based on the above information. At the same time, the control device can dynamically adjust the network topology, such as adding and deleting links, migrating virtual networks, etc. to adapt to the changing needs of quantum services.

[0119] The device management module 1002 is used to send address addition rules to the quantum gateway and control instructions to the IPv6 routing device. At the same time, it can collect the working status of the quantum gateway device and the IPv6 routing device in real time, such as collecting link utilization, data packet statistics and other data, and perform fault detection and performance analysis based on the above data.
