It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the accompanying drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For better understanding of the embodiments of the present application, the partial terms or term translations appearing during the description of the embodiments of the present application are explained as follows:
transmission Control Protocol (TCP): is a connection-oriented, reliable, byte-stream based transport-layer communication protocol that is intended to accommodate layered protocol hierarchies that support multi-network applications. Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks.
Internet Control Message Protocol (ICMP): is a subprotocol of TCP/IP protocol cluster, which is used to transfer control message between IP host and router. The control messages refer to messages of the network itself, such as network failure, whether a host is reachable, whether a route is available, and the like, and the control messages play an important role in the transmission of user data although not transmitting the user data.
ACK (acknowledgement character): the transmission control character is used to indicate that the data sent from the receiving station has been received correctly, and is generally returned to the sending station by the receiving station. Generally, in the TCP/IP protocol, if the receiving side successfully receives the data, an ACK message is replied, wherein the ACK message has a fixed format and a fixed length.
Example 1
According to an embodiment of the present application, there is provided a network connection status monitoring method for a network device, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a schematic flowchart of an optional network connection status monitoring method for a network device according to an embodiment of the present application, where as shown in fig. 1, the method at least includes steps S102-S108, where:
step S102, the network connection state of the target network device is periodically detected according to the Internet control message protocol.
Wherein, a clock mode can be adopted for periodically starting tasks.
As an optional implementation manner, before periodically detecting the network connection state of the target network device according to the internet control packet protocol, device information of the target network device may be further obtained from the database, where the device information includes: device name, device identification, and historical offline information of the target network device.
Optionally, after the device information of the network device is acquired, the first thread may be periodically invoked to execute the first timeout detecting sub-program, so as to detect whether the internet control message protocol communication timeout occurs in the target network device through the first timeout detecting sub-program.
Generally, an ICMP message is encapsulated in an IP packet, and the ICMP message, which is an aid to the IP protocol, may operate at the network layer. There is a field called TTL (Time To Live) in the IP packet To prevent the IP packet from being forwarded endlessly on the network when the router control encounters a problem and a loop condition occurs. The value is decremented by 1 for each pass through a router until the value is 0, indicating that the IP packet is discarded, and at the same time, the IP router sends an ICMP timeout message to the sender host, informing that the IP packet is discarded.
ICMP may be used in the IP protocol for sending control messages, i.e. ICMP sends information according to the IP protocol. Therefore, ICMP can be divided into two main functions, one is to determine whether an IP packet can successfully reach a target address, and the other is to diagnose a network, where two terminal programs using ICMP data packets are Ping and Traceroute, respectively, the Traceroute program is used to display a possible path between two network devices and measure a delay of the data packet on the IP network, and the Ping program is a simplified version of the Traceroute program, and thus, the Ping program is usually used in practical applications.
Ping is a common tool for detecting network connectivity, and can also collect other relevant information such as time consumed by a report packet arriving at a receiving end and returning to a sending end, so that the Ping operation principle is to send an ICMP Echo request message to the receiving end, wait for the response of the ICMP Echo response message, and judge whether the receiving end network can be reached according to whether the Echo response message is received.
In addition, the user may customize different parameters in the Ping command, such as ICMP message length, number of ICMP messages sent, timeout time waiting for reply response, etc., and the network device may construct and send an ICMP message according to the configuration parameters, and perform the Ping test, where the output information in the Ping command includes: the receiver address, the length of the ICMP message, the sequence number, the TTL value and the round trip time, wherein the sequence number is contained in the variable parameter field in the ICMP Echo reply message, and the TTL and the round trip time are contained in the IP data packet head of the message. Different purposes that can be realized when the Ping command configures different parameters can be visually shown through table 1.
TABLE 1
And step S104, when the number of times of the target network equipment for generating the internet control message protocol communication overtime exceeds a first preset threshold value is continuously detected, detecting the network connection state of the target network equipment according to the transmission control protocol.
For example, if the first timeout detection subroutine executed by the first thread detects that the timeout times of the internet control message protocol communication of the target network device exceed 10 times, the device information of the target network device is sent to another thread for detection.
Specifically, a second thread is called to execute a second timeout detection subroutine, where the second timeout detection subroutine is used to detect whether a transmission control protocol communication timeout occurs in the target network device.
Generally, in the communication process of the TCP protocol, a receiving end of the TCP returns a series of acknowledgement information to determine whether an error occurs, and once a packet loss occurs, a timeout retransmission operation needs to be started to retransmit data that has not been acknowledged. Therefore, retransmission is an important mechanism for ensuring data reliability in the TCP protocol (i.e., transmission control protocol).
There are two ways for TCP retransmission, one is time-based and the other is acknowledgement information, that is, the TCP protocol acknowledgement and retransmission are based on the premise that the data packet is acknowledged or not. Therefore, when TCP sends a message, it starts a retransmission timer, which can be divided into the following two cases: firstly, when an ACK (acknowledge character) message of a specific message is received before the timer is overtime, the timer is cancelled; secondly, if the ACK (acknowledgement character) message of a specific message is not received before the timer expires, the data message needs to be retransmitted, and the timer is reset, where the expiration of the timer is generally called Retransmission Timeout (RTO).
In practical application, a proper RTO is required to be set, so that the waste of network equipment resources can be effectively reduced, and if the RTO is too small, part of data messages are likely to be congested or the network is not good and has larger delay, so that unnecessary retransmission operation is caused; if the RTO is too large, the sending end needs to wait for a long time to find the data loss, thereby affecting the network transmission efficiency. Therefore, it is necessary to adaptively adjust the RTO according to the RTT (Round-Trip Time) in the network in combination with the actual network condition.
And step S106, when the number of times of the transmission control protocol communication timeout of the target network equipment is continuously detected to exceed a second preset threshold value, determining that the target network equipment is offline.
For example, when the second timeout detecting subroutine executed by the second thread detects that the number of times of timeout of transmission control protocol communication of the target network device exceeds 15, the target network device is determined to be offline.
Step S108, sending an offline notification message to the target terminal, wherein the offline notification message at least comprises the device information and the offline time of the target network device.
The target terminal may be, but not limited to, a mobile phone, a computer, or the like.
For example, fig. 2 shows a schematic diagram of an optional offline notification reminding interface of the target terminal, and as can be seen from fig. 2, a user can view information such as a device name, a device IP address, and device offline time of the target network device through the target terminal, thereby effectively improving the efficiency of device monitoring.
As an optional implementation manner, before sending the offline notification message to the target terminal, the device information of the target network device may also be sent to the message pushing module, the log module, and the data operation gateway.
Specifically, the message pushing module firstly sorts the offline notification messages and then accesses a Web SID API interface, updates Security Identifiers (SIDs) in a browser interface in the monitoring terminal according to the offline notification messages, and generates offline log information, where the offline log information includes device information and offline time of the target network device; then, the log module sorts the related information and sends the information to the database operation gateway; and finally, the database operation gateway updates the network connection state of the target network equipment in the database and writes offline log information into a log table of the database.
Optionally, when it is detected that the target network device is restored from the offline state to the online state, a network restoration notification message is sent to the target terminal, where the network restoration notification message at least includes device information of the target network device, network restoration time, and offline duration.
For example, fig. 3 shows a schematic diagram of an optional offline notification reminding interface of the target terminal, and as can be seen from fig. 3, a user can view information such as a device name, a device IP address, a network recovery time, and a device offline duration of the target network device through the target terminal.
As another optional implementation, before sending the network recovery notification message to the target terminal, the offline duration may also be determined according to the offline time and the network recovery time of the target network device, and network recovery log information is generated and stored in the log module, where the network recovery log information at least includes the device information, the network recovery time, and the offline duration of the target network device; then, the data operation gateway updates the network connection state of the target network equipment in the database and writes the network recovery log information into a log table of the database; and finally, the message pushing module updates the security identifier in the browser interface in the monitoring terminal according to the network recovery notification message.
In the embodiment of the application, the network connection state of the target network equipment is detected periodically according to an internet control message protocol, when the number of times of the target network equipment for generating the internet control message protocol communication overtime exceeds a first preset threshold value is continuously detected, the network connection state of the target network equipment is detected according to a transmission control protocol, and when the number of times of the target network equipment for generating the transmission control protocol communication overtime exceeds a second preset threshold value is continuously detected, the target network equipment is determined to be offline; and then sending an offline notification message to the target terminal, wherein the offline notification message at least comprises the device information and offline time of the target network device. The network connection state of the target network equipment is subjected to double detection through an internet control message protocol and a transmission control protocol, so that the accuracy of a detection result is ensured; meanwhile, when the target network equipment is detected to be offline, the offline notification message is sent to the target terminal of the maintainer in time, and the technical problem that the maintainer cannot know the network connection state of the network equipment in time in the related technology is effectively solved.

As an optional implementation manner, before periodically detecting the network connection state of the target network device according to the internet control packet protocol, the first detecting module 41 may further obtain device information of the target network device from a database, where the device information includes: device name, device identification, and historical offline information of the target network device.
Optionally, after acquiring the device information of the network device, the first detecting module 41 may execute a first timeout detecting sub-routine by periodically calling a first thread, so as to detect whether an internet control messaging protocol communication timeout occurs in the target network device through the first timeout detecting sub-routine
The second detecting module 42 is configured to detect a network connection status of the target network device according to the tcp when the number of times of timeout of the tcp communication of the target network device is continuously detected to exceed a first preset threshold.

And the notification module 44 is configured to send an offline notification message to the target terminal, where the offline notification message at least includes device information of the target network device and offline time.
