The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
The device state monitoring method provided by the disclosure can be applied to a controller, the controller can be a controller cluster or a single controller, and the physical architecture of the controller is not limited by the disclosure. The software system of the controller of the present disclosure may employ a micro-service architecture including a connection micro-service, a control micro-service, and a cache micro-service. The micro-services may be embodied in containers. In the present disclosure, the connection microservice and the control microservice may avoid resource consumption caused by full connection of the control microservice and the connection microservice by caching state information between the microservice interaction network device and the connection microservice.
Specifically, fig. 2 is a schematic architecture diagram of a micro service architecture provided by the present disclosure, and fig. 3 is a schematic flow diagram of an apparatus status monitoring method provided by the present disclosure, as shown in fig. 2 and fig. 3, the apparatus status monitoring method provided by the present disclosure includes:
in step 202, the connection microservice receives a connection request sent by a network device.
The embodiment of the present disclosure takes the network device 11 as an example to describe the provided device status monitoring method. When the network device 11 sends a connection request to the controller, the connection request is distributed to any connection microservice for processing by the load balancing module, which is described by taking the example that the connection request is distributed to the connection microservice 21. The connectivity microservice is responsible for receiving and maintaining communications with network devices.
And 204, the connection micro-service sends a write-in message to the cache micro-service, wherein the write-in message comprises the equipment information of the network equipment to be connected with the controller.
After the connection microserver 21 receives the connection request sent by the network device 11, the connection microserver 21 sends a write message to the cache microserver, where the write message includes device information of the network device 11 to which the controller is to establish a connection. Wherein the device information may be an IP address of the network device, a serial number of the network device, and the like. The network device can be a switch, a router and a firewall. The type of network device is not limited in this disclosure.
The write request is for causing the cache to write the device information of the microservice network device 11 into the cache microservice. And in turn, allows control microservice 31 and control microservice 32 to obtain information stored in the cache microservices by periodically polling the cache microservices. The information stored in the cache microservice may include: device information of the network device, connection state between the network device and the connection microservice, and identification of the connection microservice to which the network device is connected. For example, the cache microservice may store device information of the network device 11, an identifier of the connection microservice 21 corresponding to the network device 11, and a connection status between the network device 11 and the connection microservice 21.
The control microservice 31 and the control microservice 32 may further respectively obtain all information stored in the cache microservice, and determine a network device with a failed connection state and a connection microservice to which the network device is correspondingly connected.
The control microserver reads the information of one network device from the cache microserver, which means that a new device is on line, and if the device information is aged and deleted or the connection state between the network device and the connection microserver is set to be invalid, the network device is away, namely, the connection with the controller is disconnected.
After establishing a connection with the connection microservice 21, the network device 11 will periodically send keep-alive messages to the connection microservice 21. If the connection microservice does not receive the keep-alive message sent by the network device in the period exceeding the preset period, it means that the network device 11 is disconnected from the connection microservice 21. In order to enable the control microservice to know the connection state between the network device 11 and the connection microservice 21, in step 208, the connection microservice sends a write message to the cache service according to the received keep-alive message, that is, the connection microservice 21 periodically writes the connection state between the network device 11 and the connection microservice into the cache microservice, so that the control microservice knows the connection state between the network device 11 and the connection microservice 21.
Specifically, after receiving the keep-alive message sent by the network device 11, the connection microserver 21 sends a write message to the cache microserver, where the write message includes device information of the network device 11 that establishes a connection with the controller.
Corresponding to steps 202 and 204 above, the cache microserver receives the write message sent by the connectivity microserver. Specifically, the cache microservice may cause the control microservice to obtain the connection status between each network device and the connection microservice by performing steps 302-308. FIG. 4 is a schematic flow chart of the device status monitoring method executed on the cache microserver side according to the present disclosure
After receiving a write-in request sent by a connection microserver, a cache microserver determines that if the network equipment is written in for the first time according to equipment information carried by the write-in request, the cache microserver records the equipment information of the network equipment and sets Time To Live (TTL) for the network equipment; and if the cache micro-service determines that the network equipment is not written for the first time according to the write request, updating the timer corresponding to the network equipment and restarting timing.
It should be noted that different network devices may set different lifetime. The length of the TTL is determined by the writer at the time of writing.
The cache microserver utilizes a timer to count the time interval of the write requests received for the same network device twice. If the time interval of the write requests for the same network device, which are received twice before and after the cache micro-service, exceeds the lifetime, the network device and the connection micro-service may be considered to be disconnected at this time, and at this time, the connection state may be set to be invalid or the cache micro-service deletes the device information corresponding to the network device.
Of course, another possible implementation manner for step 306 is that the cache microserver for the network device receives the write information for the network device sent by the connection microserver when the timer for the network device does not exceed the lifetime, and at this time, the timer corresponding to the network device may be updated to be in the initial default state. Updating the timer to the initial default state may ensure that the timer is restarted, that is, the connection state between the network device and the connection microservice recorded in the cache microservice is ensured to be normal and valid.
In step 306, another possible implementation manner is that after the cache microserver sets the connection state of the network device and the connection microserver to be invalid, the cache microserver receives a write message for the network device sent by the connection microserver again, and then updates the timer corresponding to the network device to the initial default state so as to restart the timer.
For example, when the network device 11 first sends a connection request to the connection microserver 21, the connection microserver 21 sends a write request to the cache microserver, and the cache microserver receives the write request sent by the connection microserver 21, and according to the device information of the network device 11 carried in the write request, it can be determined that the related information of the network device 11 is first written to the cache microserver, so that the device information of the network device 11 is recorded, and a time to live TTL is set for the network device 11. Assuming that the TTL set for the network device 11 is 5S, if the timer corresponding to the network device 11 counts that the cache microserver still does not receive the write request associated with the network device 11 sent by the connection microserver 21 after exceeding 5S, at this time, it is considered that the network device 11 is disconnected from the connection microserver 21, and at this time, the cache microserver sets the connection state between the network device 11 and the connection microserver to be disabled. If the 3S is passed, the cache micro service receives the write request associated with the network device 11 sent by the connection micro service 21, which means that the connection between the connection micro service 21 and the network device 11 is normal, the connection micro service 21' can normally receive the keep-alive message sent by the network device 11, and the cache 502 micro service resets the timer corresponding to the network device 11 to the initial default state to restart the timing, so that it can be ensured that the time recorded by the timer does not exceed the lifetime corresponding to the network device, that is, it can be ensured that the connection state between the network device 11 and the connection micro service 21 recorded in the cache micro service is normal and valid.
The cache micro-service receives the read information periodically sent by the control micro-service, and the control micro-service can determine whether the connection between the network equipment and the controller is abnormal or not according to the connection state between the network equipment and the connection micro-service recorded by the read cache micro-service.
Of course, in step 306, if the cache microserver deletes the device information corresponding to the network device, the information recorded in the cache microserver read by the control microserver is the information of the network device connected to the controller, that is, the information of the network device disconnected from the connection microserver is not stored in the cache microserver, so that the load of the control microserver can be reduced when the control microserver periodically reads the information in the cache microserver.
In the prior art, there is actually a technical problem that, in a full-connection mode, if a connection microservice itself fails, is restarted, and the like, in the architecture shown in fig. 1, the connection microservice itself cannot execute any notification action, and a network device carried on the connection microservice should be disconnected with disconnection of the connection microservice, but the connection microservice itself fails, and cannot perform disconnection processing operation, and a control microservice needs to implement a set of complex mapping relationship between connection microservice and network device connection, so that a corresponding network device state can be processed after sensing a connection microservice failure. The control micro-service sends the write-in message to the cache micro-service through the connection micro-service, and when the cache micro-service does not receive the write-in message of a certain network device after the survival time is exceeded, the cache micro-service sets the connection state of the network device and the connection micro-service to be invalid or deletes the device information corresponding to the network device, so that the control micro-service can timely sense whether the network device is still connected with the controller.
When the controlling microservice determines that the connection state between the network device and the connecting microservice is abnormal, a preliminary inference is of a failure of the network device. In one implementation, if the control microservice determines that the connection states of all network devices connected to the microservice are failure states, it may preliminarily determine that the connection microservice is abnormal.
And determining a fault type according to the connection state and sending an alarm, wherein the fault type comprises a fault of the network equipment or a fault of the connection micro-service. Thereby providing more accurate alarm suggestions for maintenance personnel.

Optionally, the cache micro-service module 501 is further configured to determine whether a timer corresponding to the network device exceeds a lifetime corresponding to the network device when the cache micro-service module 501 receives a write-in message sent by the connection micro-service module 502 and addressed to the network device, and if the timer does not exceed the lifetime, the cache micro-service module 501 updates the timer to an initial default state.
Optionally, after the cache micro service module 501 sets the connection state between the network device and the cache micro service module 501 to be invalid, if the cache micro service module 501 receives a write message for the network device sent by the connection micro service module 502, the cache micro service module 501 updates the timer corresponding to the network device to an initial default state so that the timer is restarted.
The connection microservice module 502 is configured to receive a connection request sent by a network device;
