[0001] The present application belongs to the technical field of device cascade control, and in particular, relates to a network parameter configuration method, system, terminal device and storage medium. Background Art

[0002] The development of technology has made the simultaneous control of multiple devices a trend, and it has been widely used in smart home, industrial automation and other fields. For example, after using Ethernet to connect multiple multi-port devices to the same local area network, multiple multi-port devices can be controlled simultaneously. However, when multiple multi-port devices are connected to network server devices including routers in a cascade manner, once the network server device is replaced, only the multi-port devices directly connected to the network server device will reconnect to the network. Other multi-port devices in the cascade state will not be able to automatically connect to the network, and the stability is poor. Summary of the invention

[0003] In view of this, the embodiments of the present application provide a network parameter configuration method, system, terminal device and storage medium to improve the stability of the networking state of multi-network port devices in a cascade state.

[0004] A first aspect of an embodiment of the present application provides a network parameter configuration method, which is applied to a multi-network port device group. The network parameter configuration method includes:

[0005] Send DHCP Request message to DHCP server;

[0006] Determining whether the current network connection is disconnected according to whether a DHCP Ack message sent by the DHCP server is received;

[0007] If it is determined that the current network connection is disconnected, restart the DHCP process to configure the network parameters.

[0008] A second aspect of an embodiment of the present application provides a network parameter configuration method, which is applied to a DHCP server. The network parameter configuration method includes:

[0009] Receive DHCP Request messages sent by multi-network port devices;

[0010] Send a corresponding DHCP Ack message to the multi-network port device according to the DHCP Request message.

[0011] A third aspect of the embodiment of the present application provides a network parameter configuration system, the network parameter configuration system comprising a control terminal device, a DHCP server and a multi-network port device group; the multi-network port device group comprises a plurality of multi-network port devices cascaded to each other;

[0012] The control terminal device establishes a communication connection with the DHCP server and is used to manage the DHCP server;

[0013] The multi-network port device group establishes a communication connection with the DHCP server, thereby realizing data interaction between the multi-network port devices.

[0014] A fourth aspect of an embodiment of the present application provides a terminal device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the terminal device is a multi-network port device group, the processor implements the steps of the network parameter configuration method as described in the first aspect of the embodiment of the present application when executing the computer program;

[0015] When the terminal device is a DHCP server, the processor implements the steps of the network parameter configuration method as described in the second aspect of the embodiment of the present application when executing the computer program.

[0016] The fifth aspect of the embodiments of the present application provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, it implements the steps of the network parameter configuration method as described in the first aspect or the second aspect of the embodiments of the present application.

[0017] The network parameter configuration method provided in the first aspect of the embodiment of the present application is applied to a multi-network port device group. After the multi-network port device group is successfully networked, for each multi-network port device, a DHCP Request message is sent to the DHCP server; then, according to whether a DHCP Ack message sent by the DHCP server is received, it is determined whether the current network connection is disconnected; if it is determined that the current network connection is disconnected, the DHCP process is restarted to configure the network parameters.

[0018] The second aspect of the embodiment of the present application provides a network parameter configuration method, which is applied to a DHCP server. After a multi-network port device group is connected to the DHCP server, the method receives a DHCP Request message sent by the multi-network port device; and sends a corresponding DHCP Ack message to the multi-network port device according to the DHCP Request message. In this way, the stability of the networking state of the multi-network port device group in the cascade state can be effectively improved, ensuring that when the DHCP server is replaced, each multi-network port device can automatically and timely connect to the new network, which is conducive to realizing the user's simultaneous control of multiple multi-network port devices.

[0027] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0028] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0030] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. "Multiple" means "two" or "more than two".

[0031] The development of technology has made the simultaneous control of multiple devices a trend, and it has been widely used in smart home, industrial automation and other fields. For example, by using Ethernet to connect multiple multi-port devices to the same local area network, multiple multi-port devices can be controlled simultaneously, and data exchange between multi-port devices can be achieved.

[0032] Generally, IP allocation in Ethernet includes two methods: static IP allocation and automatic IP allocation. Static IP allocation means that users manually allocate IP addresses to (multi-network port) devices in the network. This method is usually used for (multi-network port) devices that require fixed IP addresses, such as network printers. Automatic IP allocation refers to the process of automatically allocating IP addresses and other network configuration information to (multi-network port) devices in the network through a DHCP (Dynamic Host Configuration Protocol) server.

[0033] However, when multiple multi-network port devices are connected to a network server device including a router in a cascade manner, once the network server device is replaced, only the multi-network port device directly connected to the network server device will reconnect to the network. Other multi-network port devices in the cascade state will not be able to automatically connect to the network, and the stability is poor.

[0034] For example, in Figure 1In the application scenario shown, taking a dual-network-port device as an example, when all dual-network-port devices are successfully networked through automatic IP allocation, when the router in the figure is replaced with another router, for dual-network-port device 1, since the connection status of port 1 of dual-network-port device 1 and the router has changed, it can be known that the router has been replaced, but for dual-network-port device 2 and other dual-network-port devices in the subsequent cascade state, since the connection status of port 1 and port 2 of each dual-network-port device has not changed, for other dual-network-port devices except dual-network-port device 1, it is impossible to know that the router has been replaced, resulting in other dual-network-port devices not being able to work normally after the router is replaced. For other multi-network-port devices cascaded with each other, this situation similar to that of cascaded dual-network-port devices will also occur.

[0035] Therefore, for mutually cascaded multi-network port devices (including dual-network port devices), an embodiment of the present application provides a network parameter configuration method, which is applied to a multi-network port device group. After the multi-network port device group is successfully networked, for each multi-network port device, a DHCP Request message is sent to the DHCP server; then, according to whether a DHCP Ack message sent by the DHCP server is received, it is determined whether the current network connection is disconnected; if it is determined that the current network connection is disconnected, the DHCP process is restarted to configure the network parameters. In this way, the stability of the networking state of the multi-network port device group in the cascade state can be effectively improved, ensuring that when the DHCP server is replaced, each multi-network port device can automatically and timely access the new network, which is conducive to the user's simultaneous control of multiple multi-network port devices.

[0036] Embodiment 1

[0037] like Figure 2 As shown, the network parameter configuration method provided in the embodiment of the present application is applied to a multi-network port device group, and includes the following steps S1 to S3:

[0038] In one embodiment, the multi-network port device group includes a plurality of multi-network port devices cascaded to each other.

[0039] In an application, a multi-network port device group may include any number of multi-network port devices, which is not limited in this application.

[0040] In the application, a multi-network port device refers to a device equipped with two or more Ethernet interfaces. This application does not limit the type of multi-network port device.

[0041] In an application, multiple multi-network port devices that are cascaded to each other may be connected in sequence according to a preset cascade order. The preset cascade order may be set according to actual needs and is not limited here.

[0042] In the application, before entering step S1, the following steps need to be performed to ensure that all multi-network port devices in the multi-network port device group have been connected to the network.

[0043] In one embodiment, before step S1, the method includes:

[0044] For each multi-port device, start the DHCP process and configure the network parameters;

[0045] The DHCP process includes:

[0046] Send a DHCP Discover message;

[0047] If a DHCP Offer message is received from the DHCP server, the DHCP Request message is sent;

[0048] If a DHCP Ack message sent by the DHCP server is received, network parameters are configured according to the DHCP Offer message.

[0049] In the application, before starting the DHCP process, you need to ensure that the DHCP server has enabled the DHCP service and made corresponding settings, such as setting the address pool range, subnet mask, default gateway, etc. This is just an example and is not limited.

[0050] In the application, for each port of each multi-network port device that is cascaded to each other, the DHCP process can be started to configure network parameters. Multiple ports of a multi-network port device can start the DHCP process at the same time, or they can be started in sequence (taking two ports as an example, one port can start the DHCP process first, and the other port can start the DHCP process later), which is not limited here; in addition, all multi-network port devices in a multi-network port device group can start the DHCP process at the same time, or they can start the DHCP process in sequence according to a preset cascade order, or they can start the DHCP process in other orders to configure network parameters, which is not limited here.

[0051] The following uses a multi-port device in a multi-port device group as an example to explain the DHCP process:

[0052] The multi-network port device sends a DHCP Discover message through broadcasting to find a DHCP server in the network. The DHCP Discover message includes a lot of information such as the message type, the MAC address of the multi-network port device, the boot file name, the source IP address, etc., which are not limited here. This information is used to help the DHCP server identify the multi-network port device and provide corresponding network configuration information;

[0053] After receiving the DHCP Discover message, if the DHCP server has an available IP address and other network configuration information, it sends a DHCP Offer message, which may include network configuration information such as IP address, subnet mask, and default gateway. It is understandable that when there are multiple DHCP servers in the network, the multi-network port device may receive multiple DHCP Offer messages.

[0054] If multiple DHCP Offer messages are received, one DHCP Offer message is selected and a DHCPRequest message is sent to the DHCP server that provided the ODHCP Offer message, requesting to accept the provided network configuration information;

[0055] After receiving the ODHCP Offer message, the DHCP server will send a DHCP Ack message to confirm that the multi-port device can use the provided network configuration information; or, if a problem occurs, the DHCP server will send a DHCP Nak message to refuse the multi-port device from using the provided network configuration information.

[0056] After receiving the DHCP Ack message, the multi-network port device configures its own network parameters according to the network configuration information provided in the DHCP Offer message.

[0057] Step S1, send a DHCP Request message to the DHCP server, and then go to step S2.

[0058] In the application, in order to ensure the network connection status of all multi-port devices in the multi-port device group, a DHCP Request message can be sent to the DHCP server, and the network connection status of the multi-port devices can be determined based on whether a DHCP Ack message sent by the DHCP server is received.

[0059] In one embodiment, step S1 specifically includes:

[0060] After each preset time interval, the DHCP Request message is sent to the DHCP server.

[0061] In the application, the time interval can be set according to actual needs and is not limited here.

[0062] In the application, one or two or more time intervals can be set for each multi-network port device in the multi-network port device group. The time interval of each multi-network port device can be the same or different; the time interval of each multi-network port device can also be set incrementally according to its cascade position in the multi-network port device group. For example, in a multi-network port device group including 5 multi-network port devices, the interval time of multi-network port device 1 can be set to 1 second, the interval time of multi-network port device 2 can be set to 2 seconds, the interval time of multi-network port device 3 can be set to 3 seconds, the interval time of multi-network port device 4 can be set to 4 seconds, and the interval time of multi-network port device 5 can be set to 5 seconds; of course, the time interval can also be set incrementally in multiples according to its cascade position in the multi-network port device group, etc., which is not limited here.

[0063] In an application, after a time interval is set for some or all of the multi-network port devices in a multi-network port device group, these multi-network port devices with the time interval set send a DHCPRequest message to the DHCP server once after each time interval.

[0064] Step S2: Determine whether the current network connection is disconnected according to whether a DHCP Ack message sent by the DHCP server is received.

[0065] In the application, if a DHCP Ack message is received from the DHCP server, it indicates that the current network connection is not disconnected, and the current network connection status can be maintained. If a DHCP Ack message is not received from the DHCP server, it is necessary to further determine whether the current network connection is disconnected. Once it is determined that the current network connection is disconnected, it is necessary to restart the DHCP process to access the network.

[0066] In one embodiment, Figure 3 As shown, step S2 specifically includes the following steps S21 to S24:

[0067] Step S21: If a DHCP Ack message sent by the DHCP server is received, it is determined that the current network connection is not disconnected, the receiving flag is cleared and the current network connection state is maintained.

[0068] In the application, one or more receive flags may be set for each multi-network port device in the multi-network port device group, and the receive flags may be initialized, for example, the initial value of the receive flag may be set to 0; one or more receive flags may also be set for at least one multi-network port device in the multi-network port device group, which is not limited here.

[0069] In the application, if the multi-network port device that has sent a DHCP Request message to the DHCP server receives a DHCP Ack message sent by the DHCP server, it indicates that the current network connection is normal. The receiving flag bit is cleared and the current network connection status is maintained.

[0070] Step S22: If the DHCP Ack message sent by the DHCP server is not received, the receiving flag is updated and the process proceeds to step S23 or S24.

[0071] In the application, if the DHCP Ack message sent by the DHCP server is not received, the receiving flag needs to be updated, so as to determine whether the current network connection is disconnected according to the updated receiving flag.

[0072] In one embodiment, updating the reception flag bit includes:

[0073] Add 1 to the current value of the receiving flag and save it.

[0074] In the application, after a multi-network port device sends a DHCP Request message to a DHCP server, if it does not receive a DHCPAck message from the DHCP server within a certain time range (the time range can be set according to actual needs), the receiving flag is updated, that is, 1 is added to the current value of the receiving flag, and the next operation is determined based on the updated receiving flag.

[0075] In an application, the preset flag bit threshold may be set according to actual needs. For example, the preset flag bit threshold may be set to 3, 5, or 7, etc. This is only an example and is not intended to be limiting.

[0076] Step S23: If the updated reception flag does not exceed the preset flag threshold, it is determined that the current network connection is not disconnected, and the process returns to the step of sending the DHCP Request message to the DHCP server.

[0077] In the application, if the DHCP Ack message sent by the DHCP server is not received, the receiving flag is updated first, and when the updated receiving flag does not exceed the preset flag threshold, the process returns to step S1.

[0078] Step S24: If the updated reception flag exceeds the preset flag threshold, it is determined that the current network connection is disconnected, and the process proceeds to step S3.

[0079] In the application, if the DHCP Ack message sent by the DHCP server is not received, the reception flag is updated first, and when the updated reception flag exceeds the preset flag threshold, it is determined that the current network connection is disconnected, and the next step needs to be entered to restart the DHCP process and configure the network parameters.

[0080] Step S3: If it is determined that the current network connection is disconnected, restart the DHCP process to configure the network parameters.

[0081] In the application, if it is determined that the current network connection has been disconnected, restart the DHCP process to configure the network parameters. The specific DHCP process is detailed in the previous content and will not be repeated here.

[0082] In one embodiment, the network parameters include at least one of an IP address, a subnet mask, a default gateway, and a DNS server.

[0083] In the application, network parameters include but are not limited to IP address, subnet mask, default gateway and DNS server.

[0084] In one embodiment, the network parameter configuration method further includes:

[0085] By querying the PHY register, determine whether the current network connection is disconnected;

[0086] If it is determined that the current network connection is disconnected, restart the DHCP process to configure the network parameters.

[0087] In applications, PHY (Physical Layer) registers can be used to configure and monitor Ethernet physical layer devices. Therefore, for multi-port devices directly connected to the DHCP server, you can also query the PHY register to quickly determine whether the current network connection is disconnected. Specifically, you can query the PHY register once every certain time interval (the interval time can be set according to time requirements and is not limited here) to determine the current network connection status.

[0088] In an application, the address of the PHY register may be obtained by referring to a data sheet of a network interface card (NIC) or documents provided by a manufacturer, and is not limited here.

[0089] In the application, if the current network connection is found to be disconnected by querying the PHY register, a new DHCP process needs to be started to configure the network parameters; if the current network connection is not disconnected by querying the PHY register, the current network connection state is maintained. The embodiment of the present application periodically sends a DHCP Request message to the DHCP server, and determines whether the network is disconnected based on whether a DHCP Ack message is received from the DHCP server. When the DHCP server is replaced, the method provided by the embodiment of the present application can quickly determine that the network has been disconnected, so that the DHCP process can be restarted in time to configure the network parameters, which can effectively improve the stability of the networking state of the multi-network port device group in the cascade state, and is conducive to the user's simultaneous control of multiple multi-network port devices.

[0090] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0091] Embodiment 2

[0092] It should be noted that the DHCP server in this embodiment may be any device having a DHCP service, for example, a router, or other devices except a router, which is not limited here.

[0093] like Figure 4 As shown, the network parameter configuration method provided in the embodiment of the present application is applied to a DHCP server, and includes the following steps S4 to S5:

[0094] Step S4: Receive a DHCP Request message sent by the multi-network port device, and proceed to step S5.

[0095] In an application, when a DHCP server receives a DHCP Request message sent by a multi-network port device, it can simultaneously receive a DHCP Request message sent by each port of multiple multi-network port devices.

[0096] In the application, after receiving the DHCP Request message, the DHCP server can process each DHCPRequest message, or put the received DHCP Request messages into a queue and then process them in a certain order (for example, according to the cascade order of multi-network port devices), which is not limited here.

[0097] In the application, if the multi-network port device sends DHCP Request messages at a set time interval, the DHCP server can also receive DHCP Request messages at a preset receiving time interval, which is greater than or equal to the time interval for the multi-network port device to send DHCP Request messages. Alternatively, the DHCP server can also be in a continuous receiving state to receive DHCP Request messages sent by the multi-network port device in a timely manner.

[0098] Step S5: Send a corresponding DHCP Ack message to the multi-network port device according to the DHCP Request message.

[0099] In the application, if the DHCP server receives DHCP Request messages sent by multiple multi-network port devices at the same time, it can reply with a corresponding DHCPAck message for the DHCP Request message sent by each port of each multi-network port device. It should be noted that the DHCP server can reply with a corresponding DHCP Ack message for the DHCP Request messages received at the same time, or it can reply to the received DHCP Request messages in a certain order (for example, in the cascade order of the multi-network port devices), which is not limited here.

[0100] In the application, before entering step S4, the following steps regarding the DHCP process need to be performed to ensure that all multi-network port devices have been connected to the network.

[0101] In one embodiment, step S4 includes:

[0102] Receiving a DHCP Discover message sent by the multi-network port device;

[0103] Sending a corresponding DHCP Offer message to the multi-network port device according to the DHCP Discover message;

[0104] If the DHCP Request message is received, a corresponding DHCPAck message is sent to the multi-network port device according to the DHCP Request message, so that the multi-network port device configures network parameters.

[0105] In this embodiment, it is also necessary to ensure that the DHCP server has enabled the DHCP service and made corresponding settings. Specifically, the DHCP server management interface can be logged in through the control terminal device, and then the DHCP service of the DHCP server can be enabled in the management interface, and the corresponding settings can be made, including but not limited to:

[0106] Set the address pool range to allocate IP addresses to multi-port devices; set the lease term, that is, the length of time that multi-port devices can use the allocated IP addresses (for example, one week, one month, or one year); set the DNS (Domain Name System) server address to provide domain name resolution services to ensure fast conversion between domain names and IP addresses; set the NTP (Network Time Protocol) server address to provide time synchronization services to ensure that the time of multi-port devices and DHCP servers is consistent; set the subnet mask to determine which subnet an IP address belongs to; set the default gateway to ensure normal communication between devices in the network, etc.

[0107] In the application, the control end device can be one of the devices such as a mobile phone, a tablet computer, a wearable device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc.

[0108] In the application, a multi-network port device sends a DHCP Discover message by broadcasting to find a DHCP server in the network. The DHCP Discover message includes a lot of information such as the message type, the MAC address of the multi-network port device, the boot file name, the source IP address, etc. This is just an example and is not limited. This information is used to help the DHCP server identify the multi-network port device and provide corresponding network configuration information.

[0109] In the application, after receiving the DHCP Discover message, if the DHCP server has an available IP address and other network configuration information, it sends a DHCP Offer message, which may include network configuration information such as IP address, subnet mask, and default gateway.

[0110] In the application, if the multi-network port device receives the DHCP Offer message, it sends a DHCP Request message to the DHCP server. If the DHCP server receives the ODHCP Offer message, it sends a DHCP Ack message to the multi-network port device, so that the multi-network port device can configure its own network parameters according to the network configuration information provided in the DHCP Offer message after receiving the DHCP Ack message; or, if a problem occurs, the DHCP server can send a DHCP Nak message to the multi-network port device to refuse the multi-network port device to use the provided network configuration information.

[0111] In the embodiment of the present application, the DHCP server receives the DHCP Request message sent by the multi-network port device, and then replies with the corresponding DHCP Ack message, so that the multi-network port device can determine whether the network is disconnected based on whether it has received the DHCP Ack message replied by the DHCP server. When the DHCP server is replaced, the method provided by the embodiment of the present application can quickly determine that the network is disconnected, so that the DHCP process can be restarted in time to configure the network parameters, which can effectively improve the stability of the networking state of the multi-network port device group in the cascade state, and is conducive to the user's simultaneous control of multiple multi-network port devices.

[0112] It should be noted that for some contents not described in detail in this embodiment, please refer to the relevant description of Embodiment 1 and will not be repeated here.

[0113] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
