[0002] With the current trend of cloudification in personal computers and servers, more and more businesses are using microservices to run on servers, with each microservice existing as a virtual device (such as a container or virtual machine). When virtual devices on the same node communicate using UDP (User Datagram Protocol), UDP packets are encapsulated sequentially through the application layer, presentation layer, session layer, transport layer, network layer, data link layer, and physical layer of the OSI (Open Systems Interconnection) model before being transmitted. For communication between virtual devices on the same node, processing UDP packets in this way is redundant, resulting in low communication efficiency and thus reducing business efficiency.

[0018] In an optional implementation, the transmission information includes a first identifier of a first virtual network device corresponding to the first virtual device and a second identifier of a second virtual network device corresponding to the second virtual device, and the preset association relationship stores multiple sets of correspondences between the two identifiers;

[0019] The step of performing a query operation on the preset association relationship based on the transmitted information to obtain the query result includes:

[0020] Based on the first identifier, a query operation is performed on the preset association relationship;

[0021] When the second identifier corresponding to the first identifier is stored in the preset association relationship, the first query result is obtained;

[0022] The step of sending the UDP packet to the second virtual device through the first virtual network device and the second virtual network device at the transport layer according to the query result includes:

[0023] When the query result is the first query result, the UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device at the transport layer.

[0024] In an optional implementation, the method further includes:

[0025] After the first virtual device sends the UDP packet to the second virtual device at the transport layer, a first state corresponding to the first virtual network device and a second state corresponding to the second virtual network device are determined.

[0026] When the first state is a preset state, the correspondence related to the first identifier is released from the preset association relationship; and / or,

[0027] When the second state is the preset state, the correspondence related to the second identifier is released from the preset association relationship.

[0028] In an optional implementation, the method further includes:

[0029] When the second identifier corresponding to the first identifier is not stored in the preset association relationship, a second query result is obtained;

[0030] When the query result is the second query result, the UDP packet is processed sequentially through the transport layer, network layer, link layer and physical layer in the OSI model to obtain the second target UDP packet;

[0031] The second target UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device.

[0032] In an optional implementation, the method further includes:

The first and second virtual devices are located on the same electronic device. Based on the transmission information, a query operation is performed on a preset association relationship to obtain the query result. Based on the transmission information, the method determines the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device. Based on the query result, the UDP packet is sent to the second virtual device at the transport layer via the first and second virtual network devices.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] To facilitate understanding of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on this application.

[0053] refer to Figure 1 , Figure 1 This is a schematic diagram of the communication structure between two virtual devices provided in this application. The communication structure between the two virtual devices provided in this application includes: a first virtual device 101, a first virtual network device 102, a second virtual device 103, and a second virtual network device 104. The first virtual device 101 and the second virtual device 103 reside on the same node, which is an electronic device, and the electronic device can be a server. When the first virtual device 101 and the second virtual device 103 communicate via UDP, the first virtual device 101 encapsulates the UDP packet and sends the encapsulated UDP packet to the second virtual network device 104 via the first virtual network device 102. The second virtual network device 104 then sends the encapsulated UDP packet back to the second virtual device 102.

[0054] refer to Figure 2 , Figure 2 This application provides a flowchart illustrating a communication method between virtual devices. The communication method between virtual devices provided in this application includes the following steps:

[0055] S101: During the process of the first virtual device sending a User Datagram Protocol (UDP) packet to the second virtual device, when the UDP packet arrives at the transport layer in the Open Systems Interconnection (OSI) model, the transmission information corresponding to the UDP packet is obtained.

[0056] Specifically, this method is applied to the communication structure between the two virtual devices described above. The executing entity is an electronic device, on which both the first and second virtual devices are mounted. The first and second virtual devices communicate via UDP. To improve the communication efficiency between the first and second virtual devices, during the process of the first virtual device sending a UDP packet to the second virtual device, after the UDP packet is encapsulated through the application layer, presentation layer, and session layer of the OSI model and reaches the transport layer, the UDP packet is truncated at the transport layer to determine the transmission information carried by the UDP packet, thereby enabling the first virtual device to send the UDP packet to the second virtual device at the transport layer.

[0057] More specifically, both the first virtual device and the second virtual device are created by electronic devices. After the electronic devices create the first and second virtual devices, in order to enable communication between the virtual devices, a first virtual network device is created for the first virtual device and a second virtual network device is created for the second virtual device. Information about the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device is recorded. When the status or configuration information of the first virtual network device is updated, the correspondence between the first virtual devices is updated synchronously. Similarly, when the status or configuration information of the second virtual network device is updated, the correspondence between the second virtual devices is updated synchronously.

[0058] S102: Based on the transmitted information, perform a query operation on the preset association relationship to obtain the query result.

[0059] Specifically, the transmission information includes a first identifier of the first virtual network device corresponding to the first virtual device and a second identifier of the second virtual network device corresponding to the second virtual device. The first virtual device and the second virtual device need to communicate through their respective corresponding virtual network devices. The transmission information carried in the UDP packet can identify the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device. After encapsulating the UDP packet, the first virtual device can send it to the second virtual device through the first and second virtual network devices. More specifically, to enable the first virtual device to transmit UDP packets to the second virtual device at the transport layer, a pre-configured correspondence between the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device is established. After obtaining the transmission information, the correspondence is queried to check whether the transmission information is stored in the correspondence, and the UDP packet is transmitted according to the query result. The aforementioned correspondence is a pre-configured relationship between virtual network devices that support UDP packet transmission at the transport layer.

[0060] S103: Based on the transmission information, determine the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device.

[0061] Specifically, the electronic device pre-stores the correspondence between identifiers and virtual devices. In order to accurately transmit UDP packets to the second virtual device, the first virtual device determines the first virtual network device corresponding to the first identifier and the second virtual network device corresponding to the second identifier through the correspondence between identifiers and virtual devices.

[0062] S104: Based on the query results, the UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device at the transport layer.

[0063] Specifically, after obtaining the query results, the first virtual network device corresponding to the first virtual device, and the second virtual network device corresponding to the second virtual device, the first virtual device can send UDP packets to the second virtual device through the first virtual network device and the second virtual network device at the transport layer based on the query results.

[0064] This application provides a communication method between virtual devices. During the transmission of UDP packets between two virtual devices, the UDP packets are truncated after reaching the transport layer. This enables one virtual device to transmit UDP packets to another virtual device at the transport layer without encapsulating the UDP packets through the seven layers of the OSI model, thereby improving communication efficiency and business efficiency.

[0065] refer to Figure 3 , Figure 3A flowchart illustrating another communication method between virtual devices provided in this application. The communication method between virtual devices provided in this application includes the following steps:

[0066] S201: During the process of the first virtual device sending a User Datagram Protocol (UDP) packet to the second virtual device, when the UDP packet arrives at the transport layer in the Open Systems Interconnection (OSI) model, the transmission information corresponding to the UDP packet is obtained.

[0067] Step S201 is the same as step S101, and will not be repeated here in this embodiment. For details, please refer to the above description.

[0068] S202: Based on the transmitted information, perform a query operation on the preset association relationship to obtain the query result.

[0069] Specifically, the transmission information includes a first identifier of the first virtual network device corresponding to the first virtual device and a second identifier of the second virtual network device corresponding to the second virtual device. Multiple sets of correspondences between the two identifiers are stored in the preset association relationship. After obtaining the transmission information, if a correspondence between the transmission information is stored in the preset association relationship (i.e., the query result is the first query result), the condition for UDP packets to be transmitted at the transport layer is met; if no correspondence between the transmission information is stored in the preset association relationship (i.e., the query result is the second query result), the condition for UDP packets to be transmitted at the transport layer is not met. More specifically, step S202 includes:

[0070] Based on the first identifier, perform a query operation on the preset association relationship;

[0071] When the second identifier corresponding to the first identifier is stored in the preset association relationship, the first query result is obtained;

[0072] If the second identifier corresponding to the first identifier is not stored in the preset association relationship, the second query result is obtained.

[0073] S203: Based on the transmission information, determine the first virtual network device corresponding to the first virtual device and the second virtual network device corresponding to the second virtual device.

[0074] Step S203 is the same as step S103, and will not be repeated here. Please refer to the above description for details. It should be noted that regardless of whether the obtained query result is the first query result or the second query result, step S203 must be executed to determine the communication bridge (first virtual network device and second virtual network device) between the first virtual device and the second virtual device, so that UDP packets are sent to the second virtual device via the first virtual network device and the second virtual network device.

[0075] S204: When it is determined from the query result that the UDP packet will be sent to the second virtual network device at the transport layer, a shallow copy of the UDP packet is performed to obtain the first target UDP packet.

[0076] Specifically, determining to send a UDP packet to the second virtual network device at the transport layer based on the query result can be understood as the obtained query result being the first query result. When the query result is the first query result, the UDP packet can be sent to the second virtual device at the transport layer via the first and second virtual network devices. To further improve the communication efficiency between the first and second virtual devices, a shallow copy is performed on the UDP packet during transmission to send the obtained first target UDP packet to the second virtual device.

[0077] More specifically, when it is determined from the query results that the UDP packet will not be sent to the second virtual device at the transport layer (i.e., the obtained query result is the second query result), the UDP packet is processed sequentially through the transport layer, network layer, link layer and physical layer in the OSI model to obtain the second target UDP packet, and the second target UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device.

[0078] The process of processing UDP packets sequentially through the transport, network, link, and physical layers of the OSI model can be understood as encapsulating the UDP packets according to the seven layers of the OSI model. After encapsulation, the encapsulated UDP packet (i.e., the second destination UDP packet) can be sent to the second virtual device to achieve communication between the first and second virtual devices. It should also be noted that, to facilitate subsequent communication between virtual devices, when the query result is the second query result, the pre-defined association relationship is updated using the correspondence between the first and second identifiers. In other words, the correspondence between the first and second identifiers is stored in the pre-defined association relationship, thereby updating the pre-defined association relationship.

[0079] S205: After obtaining the first target UDP packet, the first target UDP packet is encapsulated to obtain an encapsulated frame.

[0080] S206: After obtaining the encapsulated frame, send empty data packets to the physical layer of the OSI model sequentially through the network layer and link layer.

[0081] Specifically, regarding steps S205 and S206, when the query result is the first query result, if the first target UDP packet is directly sent to the second virtual network device at the transport layer, communication errors may occur during communication between the first and second virtual devices. To avoid errors during communication, after obtaining the first target UDP packet, it is encapsulated. After the network layer confirms that the first target UDP packet has been encapsulated at the transport layer, an empty data packet can be sent to the link layer, which then sends the empty data packet to the physical layer. This enables the simulated transmission of UDP packets. When encapsulating the first target UDP packet, the encapsulation header contains information about the second virtual network device, and the data end is the first target UDP packet.

[0082] S207: Decapsulate the encapsulated frame to obtain the first target UDP packet.

[0083] S208: At the transport layer, the first target UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device.

[0084] Specifically, regarding steps S207 and S208, since the encapsulated frame is formed by the relevant information of the second virtual network device and the first target UDP packet, decapsulating the encapsulated frame can obtain the relevant information of the receiving end (i.e., the second virtual network device) and the data to be transmitted at the transport layer (i.e., the first target UDP packet). After determining the second virtual network device and the first target UDP packet, the first target UDP packet can be sent to the second virtual device through the first virtual network device and the second virtual network device.

[0085] The communication method between virtual devices provided in this application, after the first virtual device sends a UDP packet to the second virtual device at the transport layer (that is, after the first virtual device sends a first target UDP packet to the second virtual device at the transport layer), further includes the following steps:

[0086] Determine the first state corresponding to the first virtual network device and the second state corresponding to the second virtual network device;

[0087] When the first state is a preset state, the correspondence related to the first identifier is released from the preset association relationship; and / or,

[0088] When the second state is the preset state, the correspondence related to the second identifier is released from the preset association relationship.

[0089] The preset states include a release state and a deactivation state. When the first state is the preset state, it indicates that the first virtual network device corresponding to the first identifier is no longer in use. Similarly, when the second state is the preset state, it indicates that the second virtual network device corresponding to the second identifier is no longer in use. When the first virtual network device and / or the second virtual network device are no longer in use, the corresponding relationship with its corresponding identifier must be released from the preset association relationship to reduce the query process when performing subsequent query operations on the preset association relationship.

[0090] This application provides a communication method between virtual devices. During the transmission of UDP packets between two virtual devices, the UDP packets are truncated after reaching the transport layer. This enables one virtual device to transmit UDP packets to another virtual device at the transport layer without encapsulating the UDP packets through the seven layers of the OSI model, thereby improving communication efficiency and business efficiency.

[0091] refer to Figure 4 , Figure 4 This application provides a schematic diagram of a communication device between virtual devices. The communication device between virtual devices includes: an acquisition module 10, a query module 20, a determination module 30, and a sending module 40. The acquisition module 10 is used to acquire transmission information corresponding to a User Datagram Protocol (UDP) packet when the UDP packet reaches the transport layer in the Open Systems Interconnection (OSI) model during the transmission of a UDP packet from a first virtual device to a second virtual device. The first virtual device and the second virtual device are located on the same electronic device. The query module 20 is used to perform a query operation on a preset association relationship based on the transmission information to obtain a query result. The determination module 30 is used to determine a first virtual network device corresponding to the first virtual device and a second virtual network device corresponding to the second virtual device based on the transmission information. The sending module 40 is used to send the UDP packet to the second virtual device through the first virtual network device and the second virtual network device at the transport layer based on the query result.

[0092] Optionally, the sending module 40 is further configured to:

[0093] When it is determined, based on the query result, that the UDP packet will be sent to the second virtual network device at the transport layer, the UDP packet is shallow copied to obtain the first target UDP packet;

[0094] The first target UDP packet is sent to the second virtual device through the first virtual network device and the second virtual network device at the transport layer.

[0100] Optionally, the transmission information includes a first identifier of a first virtual network device corresponding to the first virtual device and a second identifier of a second virtual network device corresponding to the second virtual device, and the preset association relationship stores multiple sets of correspondences between the two identifiers.

[0101] Optionally, the query module 20 is also used for:

During the transmission of UDP packets between two virtual devices, the UDP packets are truncated after reaching the transport layer, enabling one virtual device to transmit UDP packets to another virtual device at the transport layer without encapsulating the UDP packets through the seven layers of the OSI model, thus improving communication efficiency and service efficiency.
