Detailed Description
Aiming at the problem of network link abnormality caused by network equipment failure in the prior art, the embodiment of the application provides a control method of network data, which is applied to a control system in the network equipment and comprises the following steps: the control system determines the current running state information of the network equipment, determines whether the network equipment is abnormal according to the running state information, and then generates corresponding control instructions (a first control instruction or a second control instruction) to control the bypass system to enable the network equipment to be on-line or off-line; therefore, when the network equipment cannot normally operate, the network equipment is controlled to be disconnected, and the problem of network link abnormality caused by the fact that the network equipment cannot normally process the network data when the network data enters the network equipment is avoided.
The method in the embodiment of the application determines the running state information of the network equipment based on the control system heterogeneous with the network processing system, determines the abnormality of the network equipment according to the running state information, discovers the abnormality of the network equipment in time, namely, cannot normally process the network data, generates the first control instruction corresponding to the abnormality of the network equipment, and controls the bypass system to enable the network equipment to be disconnected, so that the network link is not influenced by the network equipment with faults, and the purpose of guaranteeing the network stability of the user is achieved.
It should be noted that, the network device described in the embodiments of the present application may be any network security platform hardware product, and for convenience of description, the network device will be hereinafter collectively referred to as a network device; the control system in the network device may be a health embedded control system having a dynamic detection function.
In order to better understand the above technical solutions, the following detailed description of the technical solutions of the present application is made by using the accompanying drawings and specific embodiments, and it should be understood that the specific features of the embodiments and the embodiments of the present application are detailed descriptions of the technical solutions of the present application, and not limiting the technical solutions of the present application, and the embodiments and the technical features of the embodiments of the present application may be combined with each other without conflict.
Referring to fig. 1, the present application provides a control method of network data, which is applied to a control system in a network device, wherein the network device comprises a control system, a network processing system, a power module and a bypass system. The method is used for avoiding the problem of network link abnormality caused by the failure of network equipment, and specifically comprises the following implementation steps:
step 101: and determining the current running state information of the network equipment.
Wherein the operation state information includes an operation state of the power module and/or an operation state of the network processing system.
Specifically, fig. 2 is a schematic structural diagram of a network device according to an embodiment of the present application. As shown in fig. 2, the network device includes a control system, a network processing system, a power module, and a bypass system. The bypass system is connected with the connector interface and is used for receiving the network data and transmitting the network data to the network processing system for processing. The connector interface may be an RJ45. The control system controls the bypass system by controlling the IO and communicates with the network processing system based on a bus (e.g., an IIC bus) while detecting the status of the power module to determine the operational status of the power module.
Further, when the power module operation state is one of the operation state information, the power supply voltage may be collected based on the digital-to-analog converter ADC. The digital filter may then be used to remove noise from the supply voltage to obtain an analog voltage. The analog voltage may then be used as reference data indicating the stability of the supply voltage as the operating state information of the power supply module.
When the operating state of the network device is one of the state information of the network device, the current state information of the network device may be determined based on the heartbeat monitoring. Specifically, the control system sends a heartbeat signal to the network processing system based on a bus (e.g., IIC bus) every first set time. And then, determining the running state of the network processing system according to whether the control system receives feedback information sent by the network processing system or not at every second set time. The second set time is greater than the first set time. In general, the length of the second set time may be set to be an integer multiple of the length of the first set time.
If yes, namely, at the second set time, the feedback signal sent by the network processing system is received, and the running state of the network processing system is determined to be an on-line state. If not, determining the running state of the network processing system as a disconnection state. And further, the running state (on-line/off-line) of the network processing system can be determined as the running state information of the network equipment.
Step 102: and determining whether the network equipment is abnormal according to the running state information.
Specifically, in response to the network device operating state being a dropped state, the network device anomaly is determined.
Further, it can also be determined whether the analog voltage is in the voltage calibration range, if not, it is determined that the analog voltage is abnormal, that is, the voltage provided by the power supply is unstable.
Further, in response to the analog voltage anomaly, a network device anomaly is determined.
In fact, for the power supply module, in addition to the above-mentioned case of unstable power supply, another possible case is: the network device is turned off, and the power supply is powered down. When the control system determines that the analog voltage is lower than the voltage threshold, the power supply module can be determined to be powered down, so that the related power-down mode parameter can be adjusted, the power-down mode parameter is used as the running state of the power supply module, and the network equipment is determined to be abnormal.
If it is determined that the error occurs, step 103 is executed; if it is determined that it is normal, step 104 is performed.
Step 103: if yes, a first control instruction is generated, and the bypass system is controlled to start a fault mechanism through the first control instruction, so that the network equipment is disconnected.
Specifically, the first control instruction may modify a register parameter in the bypass system to achieve the purpose of controlling a control circuit in the bypass system.
Fig. 3 is a schematic diagram of connection of a control circuit corresponding to a first control command according to an embodiment of the application. As shown in fig. 3, the network port No. 1 and the network port No. 2 are interfaces for receiving network data by the bypass system. When the bypass system controls the bypass system to start a fault mechanism based on the first control instruction, ab in the switches S1 and S2 in the control circuit is conducted, so that the network data No. 1 network port enters and is output from the No. 2 network port through the ab channel, and therefore the network processing system in the network equipment does not receive network data any more, and the network equipment is disconnected at the moment, so that the influence of the network equipment in the fault on a network link is effectively avoided.
Step 104: if not, generating a second control instruction, and controlling the bypass system to start a data permission mechanism through the second control instruction so as to enable the network equipment to be on line.
In particular, the second control instruction may also be used by the control system to modify a register parameter in the bypass system to achieve the purpose of controlling the control circuit in the bypass system.
In the embodiment of the application, the control system sends the second control instruction to the bypass system based on the control IO, so that the bypass system opens the control circuit in the bypass system, and further can receive the network data. The control IO may be GPIO (General Purpose Input/Output Port, general purpose input Output Port).
Fig. 4 is a schematic connection diagram of a control circuit corresponding to a second control instruction according to an embodiment of the present application. As shown in fig. 4, the control system controls ac conduction of the switches S1 and S2 in the control circuit in the bypass system based on the second control instruction, so that after the network data enters the No. 1 network port, the network data enters the bypass system in the direction shown by the arrow, and then is sent to the network processing system. After being processed by the network processing system, the network data is sent from the network processing system to the bypass system in the direction indicated by the arrow, and then is output through the No. 2 network port. At this time, the network device is on line, and the network data can be normally processed and output based on the network processing system.
Further, the embodiment of the application sets a redundant service port, ensures that the network processing system can successfully receive the network data for processing when the bypass system starts a data permission mechanism, and outputs the processed network data. Fig. 5 is a schematic diagram of a redundant service port (i.e., a redundant network port) between a network processing system and a bypass system according to an embodiment of the present application. As shown in fig. 5, in the embodiment of the present application, the number of network ports is set to be even, and 2 network ports are used as a group of network ports, where one network port is used for receiving network data, and the other network is used for outputting the network data to the bypass system. Specifically, a No. 1 net port is set, a No. 2 net port is a first net port group, and a No. 3 net port and a No. 4 net port are set as a second net port group. The first network port and the second network port are redundant network ports, and one network port can be used for transmitting/receiving data each time.
Therefore, after generating the second control instruction and controlling the bypass system to start the data permission mechanism and receive the network data, the control system can also detect whether the data transmission channel for transmitting the network data is normal. If not, a switching instruction is sent to the network processing system, so that the network processing system is switched from the current data transmission channel to the standby data transmission channel based on the switching instruction, namely, the current network port (i.e. the service port) is switched to the redundant network port corresponding to the current network port, and the network data is ensured not to be interrupted. For example, the network processing system is instructed to switch from the first set of traffic ports to the second set of traffic ports.
Further, in the embodiment of the present application, the control system may further receive a remote control of the main processor based on the corresponding message. The remote control may include mode settings such as timer reset, timing period, function enable, channel settings, power down settings, start up settings, etc. parameter settings. And a timer reset instruction for resetting the timer used for determining the first set time or the second set time to zero. The remote control modifies the parameters in the corresponding registers through the control system so as to achieve the purpose of controlling or monitoring other systems.
Fig. 6 is a schematic flow chart of remote control of the control system by the main processor according to the embodiment of the application. As shown in fig. 6, interrupt enable is first turned off to facilitate parameter setting in the relevant registers. And then receiving a message sent by the main process and indicating the setting parameters. The message is then parsed and the corresponding register parameters are modified/set according to the parameters indicated by the message. If the message includes a query instruction, register query information can be set, so that the network processing information queries corresponding content for the network data according to the query instruction. If the message includes the heartbeat information, the timing counting register is cleared so that the control system monitors the heartbeat of the network processing system according to the first set time and the second set time indicated by the heartbeat information. If the message includes information indicating the setting parameters, the parameters in the associated registers may be set based on the message. After the parameter settings/modifications of the relevant registers are completed according to the message, the interrupt enable may be turned on to exit the interrupt routine.
It should be noted that the interrupt enable is used for triggering the control system to control the bypass system when the control system detects that the power supply is abnormal or fails, and notifying the network processing system to stop working.
Fig. 7 is a schematic diagram of a control system according to an embodiment of the present application for performing heartbeat monitoring on a network device and performing power supply monitoring on a power supply module. Wherein, the power supply abnormality comprises power supply failure and unstable power supply. Referring to fig. 7, in an embodiment of the present application, a network device may be initialized at the start-up. The initialization may be for a network device to perform clock configuration, register configuration, IIC communication parameters, etc. And then inquiring the running state of the power supply, and if the running state of the power supply is abnormal, generating a first control instruction and modifying a state register in the bypass system. If the power supply running state is normal, the running state of the network processing system is queried, a first control instruction is still generated, parameters of a state register in the bypass system are modified to control the on/off of a control circuit in the bypass system, network equipment is ensured to process network data in a normal state, and a fault processing mechanism is started in an abnormal state to smoothly run off, so that the condition that the stability of a user network is reduced due to the influence of a network link is avoided. Correspondingly, if the query power state and the network processing state are not abnormal, generating a second control instruction to modify parameters corresponding to the second control instruction in the bypass switch state register, thereby achieving the purpose of controlling the bypass system.
The network device in the embodiment of the application can be deployed between an intranet and an extranet and is used for unpacking, analyzing and analyzing network behavior risks for the network flow data packet, so that the control method for the network data in the steps 101-104 can effectively avoid the problem of the isolation between the intranet and the extranet caused by the failure of the network device, and further effectively reduce the influence of the failure of the network device on enterprise business.
Further, in the embodiment of the present application, a network device is provided, where the control system is configured to execute the control method of the network data in steps 101 to 104.
The network device also comprises a network processing system for receiving the network data input by the bypass system and processing the network data according to the set rule to obtain the processed network data. And sending the processed network data to a bypass system and inputting the network data through the bypass system.
The network device further comprises a bypass system for receiving control instructions of the control system and controlling control circuits in the bypass system to start response mechanisms corresponding to the control instructions based on the control instructions.

The aforementioned control instructions include a first control instruction, a second control instruction, and the response mechanism includes a start-up failure mechanism corresponding to the first control instruction, and a data grant mechanism corresponding to the second control instruction.
The network device may also include a power module for powering the network processing system, the bypass system, and the control system. The power module comprises a first circuit and a second circuit. The first circuit is composed of a DC/DC and LDO circuit, and is connected with the network processing system and supplies power to the network processing system. The second circuit is a micro-control power supply circuit and supplies power to the control system and the bypass system, and in order to ensure that the control system can generate a first control instruction to control the bypass system when the power supply is abnormal or fails, the second circuit is required to have a power failure delaying function, so that a capacitor can be arranged in the second circuit, and the power failure delaying function is realized based on the charge-discharge principle of the capacitor. Fig. 8 is a schematic diagram of a second circuit according to an embodiment of the application. The current limiter is arranged on the positive side of the capacitor, so that the impact of instantaneous current can be reduced, and the effect of protecting the second circuit is achieved.
