[0040] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Reference Figure 1 , shows a flowchart of a method for performing data transmission based on a virtual local area network identifier provided by an embodiment of the present invention, which may specifically include the following steps:

[0042] Step S101, receiving a network access request data packet sent by a second server, where the network access request data packet is a data packet for requesting to forward target message data;

[0043] In the embodiment of the present invention, an uplink port is provided in the first server, and the uplink port can realize communication with the second server.

[0044] If the first server and the second server need to perform data transmission, the uplink port of the first server needs to be set to the port corresponding to the target message data to be forwarded.

[0045] To implement automatic port configuration of the first server, the second server may generate a network access request data packet before sending the target message data. The network access request data packet is used to request the first server to forward the target message data. The network access request data packet may carry virtual LAN identification information corresponding to the target message data. The virtual LAN identification information may be determined based on the destination address of the target message data.

[0046] The first server may receive a network access request data packet sent by the second server, so as to further implement forwarding of target message data based on analysis of the network access request data packet.

[0047] In an embodiment of the present invention, the first server and the second server may be servers in a conference, and the target message data may be message data that needs to be forwarded and processed in the conference. Specifically, to ensure data transmission security, the first server and the second server may perform data transmission within the visual network. The first server may be a visual network access device, such as a visual network router, a visual network switch, and other visual network devices; the second server may be a visual network core server in the visual network. The visual network core server is a key device in the video surveillance system and is used to manage and process large amounts of video data.

[0048] Step S102, extracting virtual local area network identification information corresponding to the target message data from the network access request data packet;

[0049] After receiving the network access request data packet, the first server may parse the network access request data packet to extract virtual local area network identification information corresponding to the target message data, such as VLAN-ID (Virtual Local Area Network Identifier).

[0050] VLAN (Virtual Local Area Network) is a logical segmentation of network users connected to the port of the second layer switch. It is not limited by the physical location of the network users but is segmented according to the needs of the users. A VLAN can be implemented on a switch or across switches. VLAN can be grouped according to the location, role, department of the network users or according to the applications and protocols used by the network users. Switch-based virtual LAN can solve the conflict domain and broadcast domain problems for the LAN.

[0051] In one embodiment of the present invention, the process of the first server extracting the virtual LAN identification information corresponding to the target message data from the network access request data packet is specifically as follows: the first server determines whether there is a preset field for representing the virtual LAN identification information in the network access request data packet; when it is determined that there is a preset field in the network access request data packet, the virtual LAN identification information corresponding to the target message data is extracted from the preset field.

[0052] In actual applications, the network access request data packet may include one or more fields, and the parsing process of the network access request data by the first server is specifically manifested as parsing each field.

[0053] The first server may first determine whether the network access request data packet contains a preset field. When the network access request data packet contains the preset field, the first server may extract the virtual local area network identification information corresponding to the target message data based on the preset field.

[0054] When the preset field does not exist in the network access request data packet, the first server may be used to generate an alarm message for notifying the second server to regenerate the network access request data packet, and send the generated alarm message to the first server.

[0055] In one example, the first server may include a CPU processor, and the CPU processor may process the data received by the first server based on the memory image IO technology. The CPU processor in the embodiment of the present invention may parse the incoming message data and extract the virtual local area network identification information corresponding to the target message data, and may also forward the target message data.

[0056] Among them, in the first server, memory-mapped I / O (MMIO for short) is a technology used to access hardware devices in a computer system. It maps the registers or memory areas of the hardware devices to the address space of the CPU, so that the CPU can directly read and write the status and data of the hardware devices through memory access instructions. The following are the main functions and advantages of memory-mapped IO:

[0057] 1. Simplify hardware access

[0058] Memory-mapped IO maps the registers of hardware devices to the memory address space, allowing the CPU to directly use memory access instructions to read and write the status and data of hardware devices. This method simplifies the complexity of hardware access and avoids the use of special I / O instructions (such as IN and OUT instructions), thereby improving programming flexibility and efficiency.

[0059] (ii) Improve performance

[0060] Since memory-mapped IO allows the CPU to operate hardware devices directly through memory access instructions, the number and complexity of instructions can be reduced, thereby improving system performance. In addition, memory-mapped IO can also utilize the CPU's cache mechanism to further increase the speed of data access.

[0061] (III) Simplify the programming model

[0062] Memory-mapped IO provides a unified programming model that allows software developers to access hardware devices as if they were accessing memory. This consistency simplifies the programming model and makes it easier for developers to write and debug code.

[0063] (IV) Support DMA (Direct Memory Access)

[0064] Memory mapped IO provides the basis for DMA (direct memory access). DMA allows hardware devices to directly access system memory without CPU intervention. By mapping the registers of hardware devices to the memory address space, the DMA controller can directly read and write these registers, thereby achieving efficient data transfer.

[0065] 5. Support multi-tasking and multi-core systems

[0066] Memory-mapped IO enables multiple tasks and multiple CPU cores to share hardware resources. By mapping the registers of hardware devices to the memory address space, different tasks and cores can access these registers concurrently, thus achieving efficient resource sharing and task scheduling.

[0067] (VI) Simplify device drivers

[0068] Memory-mapped IO simplifies the development of device drivers. Drivers can operate hardware devices directly through memory access instructions without having to deal with complex I / O instructions and interrupt processing. This makes driver development simpler and more efficient.

[0069] Step S103, adjusting the default configuration of the uplink port of the first server according to the virtual local area network identification information, and using the adjusted uplink port to receive target message data.

[0070] After extracting the virtual LAN identification information, the first server can adjust the default configuration of the current uplink port to the port corresponding to the virtual LAN identification information, and then the uplink port of the first server can receive the target message data and then forward the target message data.

[0071] Among them, the default configuration refers to the default configuration parameters preset in the device when it leaves the factory or in the initial state. These parameters are usually set by the device manufacturer to ensure that the device can work properly, covering the basic settings of the network device, such as IP address, subnet mask, default gateway, VLAN configuration, port mode, security settings, etc. The default configuration can be preset, universal, secure and modifiable. In actual applications, the default configuration does not require complex configuration when the device is used for the first time to make it work properly. And the default configuration can be applied to most common network environments and can meet basic network requirements. In addition, the default configuration contains basic security settings to prevent unauthorized access and attacks. At the same time, the modifiability of the default configuration allows users to modify and adjust the default configuration according to actual needs to meet specific network requirements.

[0072] The first server of the embodiment of the present invention can modify the default configuration based on the modifiability of the default configuration and adjust the port according to the virtual LAN identification information corresponding to the target message data currently to be forwarded, so that the first server can receive or process the target message data sent by the second server.

[0073] In one embodiment of the present invention, the first server can make default configuration adjustments to the uplink port of the first server according to the virtual LAN identification information, including: sending the virtual LAN identification information to a register in the first server; forwarding the virtual LAN identification information to the uplink port of the first server through the register to make default configuration adjustments.

[0074] In actual applications, the first server also includes a preset function module and register for realizing automatic port configuration. The CPU processor of the first server can extract the virtual LAN identification information in the network access request data packet. The preset function module can obtain the virtual LAN identification information from the CPU processor, and then send the obtained virtual LAN identification information to the register. The register can store the virtual LAN identification information on the one hand, and forward the virtual LAN identification information to the uplink port of the first server on the other hand, so as to realize the default configuration adjustment of the uplink port of the first server, so that the uplink port of the first server is also suitable for processing the target message data sent by the second server.

[0075] In an embodiment of the present invention, the first server may also determine a data processing queue corresponding to the adjusted uplink port; and add the target message data to the data processing queue for processing.

[0076] In actual applications, a large amount of target message data can be processed in the first server. In order to improve the message processing efficiency, multiple processing threads can be set in the first server. Different processing threads can correspond to different data processing queues. The correspondence between the data processing queues and ports can be pre-established in the first server so that the message data transmitted by the same port can be assigned to the same data processing queue for processing.

[0077] When the first server receives the target message data through the adjusted uplink port, the corresponding data processing queue of the adjusted uplink port in the CPU processor can be determined, and then the received target message data can be added to the data processing queue for processing.

[0078] In one example, in the data processing queue, multiple target message data to be processed may be sorted according to the order in which each target message data enters the queue.

[0079] In another example, the target message data may carry a priority attribute. After entering the queue, multiple target message data may be sorted according to the priority and the time when the target queue entered the queue. For example, first sort them from high to low by priority, and then sort them according to the time when they entered the queue with the same priority.

[0080] In another example, while the target message data is waiting to be forwarded in the data processing queue, if the priority of the target message data changes, the target message data may be re-sorted based on the latest priority of the target message data.

[0081] In one embodiment of the present invention, the first server may be composed of an uplink port, a CPU, a preset function module for realizing automatic port configuration, and a register. When the newly added preset function module in the first server is in an on state, the first server may perform data forwarding processing according to the network access request data and the target message data in accordance with the above steps S101 to S103, thereby reducing the manpower cost of operating and maintaining the equipment. At the same time, the preset function module may ensure that the default configuration of the equipment port is correctly issued, give full play to the advantages of multiple processors, process the target message data of different VLAN-IDs separately, and improve the performance of the network equipment.

[0082] In an embodiment of the present invention, the first server receives the network access request data packet sent by the second server and parses the virtual LAN identification information corresponding to the target message data to be forwarded, and then uses the virtual LAN identification information to automatically adjust the default configuration of the uplink port of the first server, so that the uplink port can support forwarding the target message data corresponding to the virtual LAN identification information. Compared with manual configuration of the virtual LAN, the configuration time is reduced and the configuration efficiency is improved. At the same time, by realizing automatic configuration of the port within the first server, even if there are second servers in different regions, there is no need for operation and maintenance personnel to go to different regions to adjust the ports of the second servers respectively, thereby reducing the cost of operation and maintenance implementation.

[0083] Reference Figure 2 , shows a flowchart of another method for performing data transmission based on a virtual local area network identifier provided by an embodiment of the present invention, which may specifically include the following steps:

[0084] Step S201, receiving a network access request data packet sent by a second server, where the network access request data packet is a data packet for requesting to forward target message data;

[0085] Step S202, extracting virtual local area network identification information corresponding to the target message data from the network access request data packet;

[0086] Step S203, adjusting the default configuration of the uplink port of the first server according to the virtual local area network identification information;

[0087] Step S204, obtaining the current uplink port of the first server, and when determining that the current uplink port is the adjusted uplink port, using the adjusted uplink port to receive the target message data.

[0088] In the first server, to ensure that the target message data can be forwarded, the current uplink port of the first server can be monitored, and it can be determined whether the current uplink port is the adjusted uplink port. If it is determined that the uplink port has been adjusted, the adjusted uplink port can be used to receive the target message data.

[0089] Step S205, adjusting the default configuration of the downlink port of the first server according to the virtual local area network identification information;

[0090] In actual applications, after the first server determines the virtual LAN identification information, if the target message data needs to be forwarded to the next-level conference terminal, the default configuration of the downlink port of the first server can be adjusted according to the LAN identification information to achieve the forwarding of the target message data from the first server to the conference terminal.

[0091] Step S206, obtaining the current downlink port of the first server, and when determining that the current downlink port is the adjusted downlink port, using the adjusted downlink port to receive the target message data.

[0092] In the first server, to ensure that the target message data can be forwarded, the current downlink port of the first server can be monitored, and it can be determined whether the current downlink port is the adjusted downlink port. If it is determined that the downlink port has been adjusted, the adjusted uplink port can be used to receive the target message data.

[0093] In an embodiment of the present invention, step S203 and step S205 may be performed synchronously. Specifically, the first server may include a preset function module and register for implementing automatic port configuration.

[0094] In one embodiment of the present invention, the downlink port of the first server can also be connected to the first server of the next level. The data transmission process from the first server to the first server of the next level can refer to the data transmission process between the first server and the conference terminal.

[0095] In an embodiment of the present invention, in an embodiment of the present invention, the first server parses the virtual LAN identification information corresponding to the target message data to be forwarded by receiving the network access request data packet sent by the second server, and then uses the virtual LAN identification information to automatically adjust the default configuration of the uplink port of the first server, so that the uplink port can support forwarding the target message data corresponding to the virtual LAN identification information, and uses the virtual LAN identification information to automatically adjust the default configuration of the downlink port of the first server, so that the downlink port can support forwarding the target message data corresponding to the virtual LAN identification information to the conference terminal. Compared with manual configuration of the virtual LAN, the configuration time is reduced and the configuration efficiency is improved. At the same time, by realizing automatic configuration of the port within the first server, even if there are second servers in different regions, there is no need for operation and maintenance personnel to go to different regions to adjust the ports of the second servers respectively, thereby reducing the operation and maintenance implementation costs.

[0096] Reference Figure 3a The present invention is a schematic diagram of a transmission structure of visual network message data in an embodiment of the present invention, wherein the visual network core server can be connected to the visual network access device, and the visual network access device can be connected to one or more visual network conferencing terminals. The visual network access device is used as a reference fixed object, and the uplink port of the visual network access device is connected to the service port of the visual network core server, and the downlink port of the visual network access device is connected to the video conferencing terminal. When the device information of the registered video conferencing terminals 1, 2, 3, 4, and 5 is allocated on the visual network core server, the corresponding data message labels are ID 10, 20, 30, 40, and 50 respectively; thus, the interfaces of the video conferencing terminals 1, 2, 3, 4, and 5 are configured with VLAN IDs 10, 20, 30, 40, and 50 respectively. For example, when a visual data packet (i.e., the target message data in the embodiment of the present invention) is sent to the video conferencing terminal 1, the VLAN ID of the message data is 10,

[0097] Reference Figure 3b , showing a schematic diagram of the transmission process of a visual network message data in an embodiment of the present invention, wherein the visual network access device may include an uplink port for data transmission with a visual network core server, a downlink port for data transmission with a visual network conference terminal, a V-FLT device for realizing data transmission based on a VLAN ID, a CPU (memory image IO may be used for data processing), and registers for data storage.

[0098] Based on the above structure in the visual network access device, during the visual network conference, the V-FLT device service process on the visual network access device is turned on by default. This service will monitor the data stream of the uplink port of the downstream visual network access device at preset intervals to see if there are special fields in the incoming message.

[0099] As above Figure 3b As shown in , the data processing flow in the visual Internet access device can be divided into processes A1 to A8.

[0100] In the A1 process, when the data packet sent by the visual network core server (i.e., the network access request data packet in the embodiment of the present invention, which is a v2v network access packet) enters the uplink port of the visual network access device, the V-FLT device service process A3 senses that the A2 data stream enters the CPU, and the CPU forwards, processes and parses the data packet, and extracts special fields (such as VLAN ID) from the data packet. The V-FLT device service process A4 can obtain the VLAN ID from the CPU, and then the VLAN ID string can be stored in the register through the V-FLT device service process A6, which will be sent to the access device port configuration by the register service processes A7 and A8. At this time, the V-FLT device service processes A3 and A5 will monitor whether the default configurations of the uplink port and the downlink port on the visual network access device are correctly issued.

[0101] When it is determined that the default configurations of the uplink port and the downlink port on the visual network access device are correctly issued, the visual network access device can receive the target message data from the visual network core server, and after processing by the CPU processor, send the forwarding data packets of the target message data to the output queue in sequence, and then send them to the designated downlink port to configure the default VLAN ID, so as to forward the forwarding data packets of the target message data to the conference terminal.

[0102] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
