[0002] The fifth generation mobile communication technology (5G), with its significant advantages of high data rate, low latency, large connection and high reliability, is gradually becoming a key force in promoting the digital transformation of various industries. The intranet of most enterprises adopts the traditional multi-layer wired network architecture, which gradually reveals its limitations in the face of the growing demand for data transmission, device connection and real-time requirements. On this basis, most enterprises have begun to carry out 5G network informatization transformation, that is, by superimposing 5G network on the existing enterprise intranet, taking advantage of the high performance characteristics of 5G technology, breaking the traditional network architecture and realizing the flattening of the enterprise intranet.

Summary of the invention

[0041] A method and device for detecting the operating status of a lower computer provided in an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0042] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0043] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0044] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0045] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0046] In the wave of digital transformation, 5G is not just a simple upgrade of mobile communication technology, but also a key driving force for in-depth changes in the industry. With its significant advantages of high data rate, low latency, large number of connections and high reliability, 5G technology is gradually becoming a key force in promoting digital transformation in various industries.

[0047] At present, the application of traditional multi-layer wired network architecture in enterprise internal networks has met the basic communication needs of enterprises to a certain extent, but with the expansion of business scale and the deepening of digital transformation, its limitations are becoming increasingly prominent. First, the multi-layer network architecture increases the complexity and delay of data transmission, making it difficult to meet application scenarios with high real-time requirements. Secondly, the network management hierarchy is complex, the operation and maintenance costs are high, and monitoring blind spots are prone to occur, affecting the effective monitoring of equipment in production and management areas by enterprises. Finally, the traditional network architecture has deficiencies in scalability and flexibility, making it difficult to quickly adapt to changes in the needs of enterprise business development.

[0048] Therefore, most enterprises have begun to carry out 5G network informatization transformation. By setting up 5G networks in existing enterprise intranets and utilizing the high performance characteristics of 5G technology, they can break the traditional multi-layer network architecture and realize the flattening of enterprise intranets. However, in the process of 5G network informatization transformation, enterprises also face many challenges. When enterprises carry out 5G network informatization transformation, the original network equipment management architecture of the enterprise production area and management area may change, resulting in the inability to effectively monitor the operating status of the lower-level computers, thereby affecting the enterprise's informatization operation and maintenance management.

[0049] In order to solve the above technical problems, the embodiment of the present application provides a method for detecting the operating status of a lower computer. The gateway can determine its own working mode and the connection status of its own physical interface. After that, the gateway can detect whether the lower computer connected to it is online or offline according to its own working mode and the connection status of its own physical interface. In this way, the gateway can effectively monitor the operating status of the lower computers in the production area and management area of ​​the enterprise, thereby improving the level and efficiency of the enterprise's information operation and maintenance management work.

[0050] Figure 1 The following is an architecture diagram of a lower computer operation status detection system provided in an embodiment of the present application, such as Figure 1 As shown, the system architecture includes: a gateway 101 and a lower computer 102.

[0051] In the embodiment of the present application, the gateway 101 may be a gateway device that connects different networks and provides network communication and data transmission services for different networks. The gateway may include but is not limited to: a router, a switch, and a virtual private network (VPN) device.

[0052] The lower computer 102 may be a hardware device that directly controls field equipment (such as sensors) and obtains field equipment status data. The lower computer may include but is not limited to: a microcontroller, a programmable logic controller (PLC), an embedded control board, etc.

[0053] The gateway 101 can determine its own working mode and the connection status of the physical interface, and based on the working mode and the connection status of the physical interface, detect the operating status of the lower computer 102, that is, detect whether the lower computer 102 is online or offline. The specific process is described in the following embodiments and will not be repeated here.

[0054] Optionally, the gateway 101 can determine the address query result of the lower computer 102 based on the IP address ARP table of the lower computer 102 based on the working mode being the bridging mode, and then detect the operating status of the lower computer based on the address query result of the lower computer 102 and the connection status of the physical interface.

[0055] Optionally, based on the above, when the address query result indicates that the MAC address of the lower computer 102 exists in the ARP table, and the connection status of the physical interface of the gateway 101 is normal, the gateway 101 can determine that the lower computer 102 is online.

[0056] When the address query result indicates that the MAC address of the lower computer 102 does not exist in the ARP table, and / or the connection status of the physical interface is disconnected, the gateway 101 may determine that the lower computer 102 is in an offline state.

[0057] Optionally, the gateway 101 obtains the source address and destination address of the data packet sent by the lower computer 102 based on the working mode being the routing mode or the tunnel mode, and then detects the operating status of the lower computer 102 based on the connection status of the physical interface and the source address and destination address of the data packet sent by the lower computer 102.

[0058] Optionally, when the connection status of the physical interface of the gateway 101 is normal, if the gateway 101 obtains a preset network address range, and the source address and the destination address are within the preset network address range, the gateway 101 can determine that the lower computer 102 is online.

[0059] In the case that the gateway 101 does not obtain the preset network address range, if the source address and the destination address are not the addresses of the gateway 101 interface, and the source address and the destination address belong to the preset type address, the gateway 101 can determine that the lower computer 102 is online. If the source address and the destination address do not belong to the preset type address, the gateway 101 can determine that the lower computer 102 is offline.

[0060] In some embodiments, the gateway 101 may send a data request to the lower computer 102. Accordingly, after receiving the data request sent by the gateway 101, the lower computer 102 may parse the data request and perform corresponding operations (such as reading data, writing data, etc.) according to the data request. After completing the corresponding operation, the lower computer 102 encapsulates the operation result into a response message and sends the response message to the gateway 101.

[0061] Figure 2 A schematic diagram of a flow chart of a method for detecting the operating status of a lower computer provided in an embodiment of the present application, wherein the method comprises Figure 1 The gateway 101 shown executes, Figure 2 As shown, the method includes:

[0062] S201, determining the working mode of the gateway and the connection status of the physical interface.

[0063] The connection status of the physical interface of the gateway includes normal connection and disconnected connection.

[0064] In the embodiment of the present application, the physical interface of the gateway may include but is not limited to: an Ethernet interface (EI) (also referred to as a network port), a universal serial bus (USB) interface, a fiber optic interface or a serial interface (SI).

[0065] In the embodiment of the present application, the lower computer is connected to the gateway via a physical interface. A normal connection means that the physical interface connection between the gateway and the lower computer has been established, and a disconnected connection means that the physical interface connection between the gateway and the lower computer has been interrupted.

[0066] In some embodiments, the working mode of the gateway includes a bridging mode, a routing mode, or a tunneling mode. The bridging mode means that the lower computer is connected to the gateway through a bridge (which may be called a bridge), the routing mode means that the lower computer is connected to the gateway through a routing method, and the tunneling mode means that the lower computer is connected to the gateway through a tunnel mechanism such as a generic routing encapsulation (GER) or a virtual extensible local area network (VXLAN).

[0067] Specifically, the gateway can determine whether its working mode is a bridge mode, a routing mode, or a tunnel mode. At the same time, the gateway can determine whether the connection state of its physical interface is normal or disconnected.

[0068] S202, detecting the operating status of the lower computer based on the working mode and the connection status of the physical interface.

[0069] The running status includes an online status or an offline status.

[0070] Specifically, after the gateway determines its own working mode and the connection status of the physical interface, it can determine whether the lower computer is in an online state or an offline state based on the working mode and the connection status of the physical interface.

[0071] Based on the above technical solution, the gateway can determine whether its working mode is bridge mode, routing mode or tunnel mode. At the same time, the gateway can also determine whether the connection status of its physical interface is normal or disconnected. After determining its own working mode and the connection status of the physical interface, the gateway can detect whether the lower computer connected to it is online or offline based on its own working mode and the connection status of its own physical interface. In the above way, the gateway can effectively monitor the operating status of the lower computers in the production area and management area of ​​the enterprise, thereby improving the level and efficiency of the enterprise's information operation and maintenance management work.

[0072] In an optional implementation, the working mode of the above-mentioned gateway may be a bridge mode, or a routing mode or a tunnel mode. The following takes (1) the working mode of the gateway as a bridge mode, and (2) the working mode of the gateway as a routing mode or a tunnel mode as an example. Figure 2 The method shown is described in detail.

[0073] (1) The working mode of the gateway is bridge mode

[0074] Figure 3 is a flow chart of a method for detecting the operating status of a lower computer provided in an embodiment of the present application, such as Figure 3 As shown, the method includes:

[0075] S301, determining the working mode of the gateway and the connection status of the physical interface.

[0076] S302, based on the working mode of the gateway being the bridge mode, query the ARP table according to the IP address of the lower computer to determine the address query result of the lower computer.

[0077] The address query result is used to indicate that the MAC address of the lower computer exists in the ARP table, or that the MAC address of the lower computer does not exist.

[0078] In some embodiments, the ARP table stores a mapping relationship between the IP address and the MAC address of the lower computer. The gateway can query the ARP table to check whether there is a MAC address corresponding to the IP address of the lower computer in the ARP table.

[0079] Specifically, when the working mode of the gateway is the bridge mode, the gateway can query the ARP table according to the IP address of the lower computer to obtain the address query result of the lower computer. The gateway can determine whether there is a MAC address corresponding to the IP address of the lower computer in the ARP table according to the address query result.

[0080] S303, detecting the operation status of the lower computer based on the address query result of the lower computer and the connection status of the physical interface.

[0081] Specifically, the gateway can determine whether the lower computer is online or offline based on the address query result of the lower computer, that is, whether the MAC address of the lower computer exists in the ARP table, and the connection status of the physical interface of the gateway itself.

[0082] In some embodiments, when the address query result indicates that the MAC address of the lower computer exists in the ARP table, and the connection status of the physical interface of the gateway is normal, the gateway can determine that the lower computer is online.

[0083] For example, Figure 4 As shown, when the working mode of the gateway is bridge mode, the gateway first obtains the IP address of the lower computer, and when the IP address of the lower computer is obtained, it queries the ARP table according to the IP address of the lower computer. At the same time, the gateway determines the connection status of its own EI network port and USB interface. If the MAC address corresponding to the IP address of the lower computer is obtained, and the connection status of the EI network port or USB interface of the gateway is UP (i.e., the connection is normal), it can be determined that the lower computer is online.

[0084] In other embodiments, when the address query result indicates that the MAC address of the lower computer does not exist in the ARP table, the gateway may determine that the lower computer is in an offline state.

[0085] Optionally, when the connection status of the physical interface of the gateway is disconnected, the gateway may determine that the lower computer is in an offline state.

[0086] Optionally, when the address query result indicates that the MAC address of the lower computer does not exist in the ARP table, and the connection status of the physical interface of the gateway is disconnected, the gateway can determine that the lower computer is offline.

[0087] (2) The working mode of the gateway is routing mode or bridging mode

[0090] In some embodiments, the gateway may obtain link tracking information through a link tracking (conntrack) component of the Linux system or a system file (such as nf_conntrack), and determine the connection status of the physical interface through the link tracking information. The link tracking information includes but is not limited to: the source address, destination address, source port, destination port, protocol type and connection status of the data packet sent by the lower computer.

[0091] S502, based on whether the working mode of the gateway is routing mode or tunnel mode, obtain the source address and destination address of the data packet sent by the lower computer.

[0092] In some embodiments, the gateway may obtain link tracking information through a link tracking (conntrack) component of the Linux system or a system file (such as nf_conntrack), and obtain the source address and destination address of the data packet sent by the lower computer through the link tracking information.

[0093] S503, detecting the running state of the lower computer based on the connection state of the physical interface and the source address and the destination address of the data packet sent by the lower computer.

[0094] Specifically, the gateway can determine whether the lower computer is online or offline based on the connection status of the physical interface and the source address and destination address of the data packet sent by the lower computer obtained based on the link tracking information.

[0095] In some embodiments, the gateway may obtain a preset network address range. When the connection status of the physical interface of the gateway is normal and the gateway obtains the preset network address range, if the source address and destination address of the data packet sent by the lower computer are within the preset network address range, the gateway determines that the lower computer is online.

[0096] Optionally, based on the above, if the source port and the destination port of the data packet sent by the lower computer are within a preset network address range, the gateway can determine that the lower computer is online.

[0097] Optionally, based on the above, if the source address, destination address, source port and destination port are within a preset network address range, the gateway can determine that the lower computer is online.

[0098] In other embodiments, when the connection status of the physical interface of the gateway is normal and the gateway has not obtained the preset network address range, if the source address and destination address of the data packet sent by the lower computer are not the address of the gateway interface, and the source address and destination address belong to the preset type address, the gateway determines that the lower computer is online.

[0099] The preset address types include Class A addresses, Class B addresses and Class C addresses.

[0100] Optionally, when the connection status of the physical interface of the gateway is normal and the gateway has not obtained the preset network address range, if the source address and the destination address are not the addresses of the gateway interface and the source address and the destination address do not belong to the preset type address, the gateway determines that the lower computer is offline.
