[0003] However, existing data stream transmission methods in remote USB control systems suffer from numerous issues. The lack of precise and rational device-level categorization leads to a lack of targeted resource allocation and transmission strategy development.

[0033] Example 1

[0034] Figure 1A flowchart of a data stream transmission method is provided for the first embodiment of the present invention. This embodiment is applicable to a remote USB control system, including: a remote control terminal and various local devices. The method can be executed by a data stream transmission device, which can be implemented in the form of hardware and / or software and can be configured in a computer controller. Figure 1 As shown, the method includes:

[0035] S110. Obtain a control instruction from the remote control terminal, and determine a target proximal device and its corresponding device level based on the control instruction, wherein the device level includes a first-class premium device, a first-class non-premium device, and a second-class device.

[0036] A remote USB control system refers to a system that allows users to remotely control locally connected USB devices. It consists of a remote control terminal and various local devices. The remote control terminal can issue commands and receive feedback to local devices, just as if they were operating locally. This allows for remote device management, overcoming distance limitations. This is commonly used in teleworking and remote monitoring scenarios. The remote control terminal is a remote device or software platform, such as a computer or mobile app, that allows users to issue various operational commands. Local devices, such as cameras and printers, are located locally and close to the actual business scenario. These devices connect to the system via USB ports, receive commands from the remote control terminal, and perform corresponding actions. Control commands are instructions sent by the remote control terminal, conveying the user's intended operation and instructing the local device to perform a specific action, such as starting video recording or adjusting the camera angle. The target local device is the specific device selected by the control command among multiple local devices to perform the corresponding action. Device level is used to distinguish different proximal devices in terms of data transmission requirements, importance, etc., and the levels of proximal devices include Class 1 Premium devices, Class 1 Non-Premium devices, and Class 2 devices.

[0037] Specifically, Class 1 Premium devices are near-end devices that enjoy priority and high-quality resource allocation for data transmission. They typically have extremely high requirements for real-time data transmission, stability, and bandwidth, and must ensure efficient and reliable data transmission. Class 1 Non-Premium devices have a lower data transmission priority than Class 1 Premium devices. Although they also have certain transmission needs, their importance and real-time requirements are relatively lower. Class 2 devices, on the other hand, are near-end devices with relatively low requirements for real-time data transmission and bandwidth, and thus have a relatively low priority in system resource allocation.

[0038] S120: When the device level is a non-preferred device, determine a target bandwidth corresponding to the target near-end device, and determine bandwidth sufficiency based on the target bandwidth.

[0039] The target bandwidth is the network bandwidth required for the target near-end device to stably and smoothly complete the transmission task. The bandwidth sufficiency refers to the determination of whether the available bandwidth in the current network environment can meet the needs of the target near-end device, including whether the bandwidth is sufficient or insufficient.

[0040] Optionally, determining the bandwidth sufficiency based on the target bandwidth includes: determining the remaining bandwidth of the current transmission network; judging whether the target bandwidth is less than or equal to the remaining bandwidth, and if so, determining that the bandwidth sufficiency is sufficient; otherwise, determining that the bandwidth sufficiency is insufficient.

[0041] Specifically, the controller determines the remaining bandwidth of the current transmission network and compares the target bandwidth with the remaining bandwidth. If the target bandwidth is less than or equal to the remaining bandwidth, it indicates that the current network resources are sufficient to support the video stream transmission of the target near-end device, so the bandwidth sufficiency is determined to be sufficient. If the target bandwidth exceeds the remaining bandwidth, it indicates that the existing network resources cannot meet the demand. At this time, it is necessary to determine that the bandwidth sufficiency is insufficient.

[0042] S130: Transmit data streams between the remote control terminal and the target near-end device based on sufficient bandwidth.

[0043] Optionally, data stream transmission is performed between the remote control end and the target near-end device based on bandwidth sufficiency, including: when the bandwidth sufficiency is sufficient, creating a transmission service interface according to the target bandwidth, and performing data stream transmission between the remote control end and the target near-end device through the transmission service interface; when the bandwidth sufficiency is insufficient, polling each of the first-class non-preferred devices that are communicating in turn to determine the transmission bandwidth; arranging each of the first-class non-preferred devices in order of transmission bandwidth from large to small to generate a device transmission queue; determining the target non-preferred device from the device transmission queue in turn, reducing the transmission bandwidth of the target non-preferred device according to the specified time slot, and obtaining the corresponding updated bandwidth; until the updated bandwidth is greater than or equal to the target bandwidth, starting the data stream transmission between the remote control end and the target near-end device.

[0044] If the Bandwidth Sufficient condition is "Sufficient Bandwidth," the current network environment can provide the target near-end device with transmission resources that meet its needs. The system then creates a transmission service interface based on the target near-end device's target bandwidth. This service interface is a dynamic flex interface that can independently transmit the corresponding video stream data.

[0045] Specifically, when bandwidth is insufficient, the system adjusts the bandwidth of each communicating Class A non-preferred device to meet the data stream transmission needs of the target near-end device. First, the system polls each communicating Class A non-preferred device in turn. For example, in a network environment containing multiple Class A non-preferred devices, the system queries the actual transmission bandwidth currently used by each device one by one, and arranges each Class A non-preferred device in descending order of transmission bandwidth to generate a device transmission queue.

[0046] It's important to note that the device transmission queue also serves as a priority list for non-preferred devices. Devices with greater bandwidth are ranked higher, meaning they will be prioritized for bandwidth reduction in subsequent adjustments. For example, if there are three Class A non-preferred devices—Device A currently has a transmission bandwidth of 80 Mbps, Device B has a bandwidth of 60 Mbps, and Device C has a bandwidth of 40 Mbps—then the resulting device transmission queue order is A, B, and C. The system will identify the target non-preferred devices, starting at the head of the device transmission queue, and reduce their transmission bandwidth according to a specified time slot. A specified time slot is the smallest allocation unit in FlexE, and can be a time slice, meaning the system adjusts device bandwidth within that time slice. For example, if each time slot is set to 1 second, the bandwidth of the target non-preferred device will be reduced by 10 Mbps during each time slot. After each bandwidth reduction, the system will obtain the updated bandwidth for that device. The system will continue to reduce the bandwidth of each Class A non-preferred device in the device transmission queue until the updated bandwidth obtained is greater than or equal to the target bandwidth of the target near-end device.

[0047] Optionally, after transmitting the data stream based on sufficient bandwidth, the method further includes: when a stop transmission instruction is obtained from the remote control end, determining the idle bandwidth based on the stop transmission instruction; determining the target non-preferred devices from the device transmission queue in turn, and increasing the transmission bandwidth of the target non-preferred devices according to the specified time slot until the idle bandwidth is allocated.

[0048] The stop transmission command is used by the remote control end to stop data transmission with a USB local device that is currently communicating. This releases some of the previously occupied bandwidth, known as idle bandwidth. In other words, when the remote control end issues the stop transmission command, the system has an opportunity to reallocate bandwidth resources.

[0049] Specifically, receiving a stop transmission command indicates that the target bandwidth previously allocated for this transmission has been released. For example, to meet the data transmission needs of the target near-end device, the bandwidth of other non-preferred devices was adjusted, resulting in 50 Mbps of transmission bandwidth for the target near-end device. Upon receiving the stop transmission command, the 50 Mbps becomes idle bandwidth. The system then identifies the target non-preferred devices from the previously generated device transmission queue. Because bandwidth was previously insufficient, the bandwidth of each device was reduced according to designated time slots to meet the transmission needs of the target near-end device. To restore proper allocation of network resources, the bandwidth of each device in the list needs to be gradually increased. For example, the designated time slot was previously set to 1 second, with bandwidth increases of 10 Mbps each time. Starting from the head of the device transmission queue, the bandwidth of each target non-preferred device is increased by 10 Mbps each time slot. The system continues to increase bandwidth until all the idle bandwidth has been allocated. By allocating idle bandwidth, the system can effectively reallocate the released bandwidth to the device whose bandwidth was previously adjusted after the data transmission is completed, restoring the network bandwidth to its original state and ensuring normal data transmission for other devices.

[0050] Optionally, the method also includes: when the device level is a Class I premium device or a Class II device, obtaining a target service interface corresponding to the target proximal device; transmitting data streams between the remote control end and the target proximal device through the target service interface, wherein the target service interface includes an independent service interface and a public service interface, the independent service interface is dedicated to each Class I premium device, and the public service interface is shared by each Class II device.

[0051] It should be noted that the system will create corresponding clientI_high service interfaces for Class I premium devices based on the bandwidth required for service transmission through dynamic flexe interfaces, and stipulate that the "premium device" will always occupy the clientI_high premium service interface, even if the remote control end does not initiate a data request for the near-end device or the remote end actively abandons the video transmission of the device. In addition, since Class II devices are non-video devices, they do not have high requirements for the real-time performance of network data and can tolerate a certain amount of data delay (such as USB printers, USB smart refrigerators, etc.). Therefore, the system will create a common flexe service interface clientII for each Class II device, and the data streams of all "Class II devices" are transmitted through this service interface clientII.

[0052] Specifically, when the system determines that the target near-end device is a Class 1 Premium device, it will obtain its dedicated independent service interface. Class 1 Premium devices typically perform tasks requiring extremely high data transmission quality, real-time performance, and security, such as high-definition video transmission equipment used in telemedicine surgeries. Independent service interfaces ensure that data transmission is not interfered with by other devices. The system uses internal configuration files to locate the target service interface (independent service interface) corresponding to the target near-end device. After obtaining the independent service interface, data flows between the remote control and the target near-end device are transmitted over this dedicated channel. Furthermore, the independent service interface can be customized to meet the specific requirements of Class 1 Premium devices, such as higher bandwidth guarantees, stricter encryption mechanisms, and faster error recovery strategies. If the target near-end device is a Class 2 device, the system will assign it a public service interface. Class 2 devices use this public service interface to transmit data streams with the remote control. Public service interfaces utilize shared resources, meeting the basic transmission requirements of multiple Class 2 devices while achieving efficient resource utilization. The system allocates bandwidth resources to the public service interface based on the transmission requests and data volume of each Class II device using a built-in scheduling algorithm. For example, a round-robin algorithm is used, where each Class II device takes turns obtaining bandwidth access to the public service interface within a fixed time period and transmits data to the remote control terminal in turn, ensuring that all Class II devices can interact normally.

[0053] The technical solutions of the embodiments of the present invention, by clearly classifying device levels, can more accurately allocate data stream transmission resources to different types of devices, ensuring that critical devices receive priority. They can also determine target bandwidth and assess bandwidth sufficiency for a class of non-preferred devices. This allows for the development of more appropriate transmission strategies based on actual network conditions and device requirements, mitigating transmission issues caused by insufficient bandwidth and improving transmission stability and smoothness. Targeted data stream transmission based on different device levels and bandwidth availability helps reduce transmission conflicts and congestion, improving the performance and responsiveness of the entire remote USB control system.

[0054] Example 2

[0055] Figure 2 This is a flow chart of a data stream transmission method provided by the second embodiment of the present invention. This embodiment describes the specific process of determining the target proximal device and its corresponding device level based on the control instruction based on the above embodiment. Therefore, it will not be described in detail in this embodiment. Figure 2 As shown, the method includes:

[0056] S210: Obtain control instructions from the remote control terminal.

[0057] S220: Determine the target device identifier in the control instruction, and determine the target near-end device from the near-end devices according to the target device identifier.

[0058] S230: Determine a device type corresponding to the target near-end device, where the device type includes a video device and a non-video device.

[0059] S240: Determine whether the device type is a video device. If so, execute S250; otherwise, execute S280.

[0060] Specifically, the control command contains a target device identifier, which is the unique identifier of each near-end device. The system uses this identifier to quickly screen multiple near-end devices and identify the target near-end device. Device types are categorized as video devices and non-video devices.

[0061] It's well known that video devices often bear the heavy responsibility of capturing and transmitting real-time images. For example, cameras and surveillance cameras are used in security monitoring scenarios, or live broadcast cameras in distance learning. The video streams they output have extremely high requirements for timeliness and consistency, so video devices are classified as Class I devices. Non-video devices, such as ordinary USB printers and external hard drives, are primarily used for storage and printing tasks and do not involve critical video transmission tasks. Therefore, they have lower requirements for immediacy of transmission, so they are considered Class II devices.

[0062] S250: Determine whether the preferred device list contains the target device identifier. If so, execute S260; otherwise, execute S270.

[0063] Specifically, when the target proximal device is determined to be a video device, the system will further obtain a list of preferred devices, which records the information of video devices that are identified as preferred. The system will compare the identifier of the target proximal device with the list of preferred devices. If the target proximal device is in the list, it can be determined that the target proximal device is a first-class preferred device, and if the target proximal device is not in the list, it can be determined that the target proximal device is a first-class non-premium device. For example, a high-end 4K video conferencing camera is included in the list of preferred devices due to its performance and importance. When it receives a control command, it will be determined as a first-class preferred device; an ordinary standard-definition camera is not on the list and is a first-class non-premium device.

[0064] S260: Determine that the device level is a Class A premium device.

[0065] S270: Determine that the device level is a Class I non-premium device.

[0066] S280: Determine that the device level of the target proximal device is a Class II device.

[0067] Optionally, the system can set the bandwidth allocation ratio according to the specific application scenario. For example, 75% of the bandwidth can be allocated to all Class I devices and 25% of the bandwidth can be allocated to all Class II devices.

[0068] The technical solution of this embodiment of the present invention improves the accuracy of device identification and classification by determining the device level based on its actual type and its matching status in the preferred device list. This enables the system to more rationally allocate resources while ensuring the data stream transmission quality of important video devices. This avoids wasting resources on unimportant or non-critical devices, improves resource utilization efficiency, and ensures the stable operation of the entire remote USB control system.

[0077] Optionally, the device also includes: an idle bandwidth allocation module, which is used to determine the idle bandwidth based on the stop transmission instruction when a stop transmission instruction is obtained from the remote control end after data stream transmission is performed according to sufficient bandwidth; determine the target non-preferred device from the device transmission queue in turn, and increase the transmission bandwidth of the target non-preferred device according to the specified time slot until the idle bandwidth is allocated.

[0078] Optionally, the data stream transmission module 330 is also used to: when the device level is a Class I premium device or a Class II device, obtain the target service interface corresponding to the target proximal device; and transmit the data stream between the remote control end and the target proximal device through the target service interface, wherein the target service interface includes an independent service interface and a public service interface, the independent service interface is dedicated to each Class I premium device, and the public service interface is shared by each Class II device.

[0079] The technical solutions of the embodiments of the present invention, by clearly classifying device levels, can more accurately allocate data stream transmission resources to different types of devices, ensuring that critical devices receive priority. They can also determine target bandwidth and assess bandwidth sufficiency for a class of non-preferred devices. This allows for the development of more appropriate transmission strategies based on actual network conditions and device requirements, mitigating transmission issues caused by insufficient bandwidth and improving transmission stability and smoothness.
