Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a network line status monitoring method according to an embodiment of the present invention.
The network line state monitoring method provided by the embodiment of the invention is suitable for a video conference terminal, and comprises the following steps:
s11, acquiring the IP address of the destination terminal and the preset threshold value for monitoring the network state;
s12, inquiring all intermediate routing addresses from the video conference terminal to the destination terminal according to the IP address;
s13, acquiring monitoring data of network state monitoring based on ICMP message transmission between the video conference terminal and each intermediate routing address;
and S14, when the numerical value of the monitoring data of the video conference terminal to any one of the intermediate routing addresses exceeds the corresponding preset threshold value, judging that the network state from the video conference terminal to the intermediate routing address is abnormal.
Preferably, the network status monitoring is any one of the following: packet loss rate monitoring, network delay monitoring, network jitter monitoring and line bandwidth monitoring.
It should be noted that preset thresholds for packet loss rate monitoring, network delay monitoring, network jitter monitoring, and line bandwidth monitoring need to be set according to actual network conditions, and no requirement is made here. It can be understood that, when the network state monitoring is packet loss rate monitoring, the monitoring data of the network state monitoring is packet loss rate data, and if the packet loss rate data exceeds a preset threshold, it is determined that the packet loss rate data is abnormal, and the abnormal packet loss rate data is actively reported, so that a maintainer and a developer overhaul a corresponding network line.
In some preferred embodiments, the step S12 specifically includes:
sending an IP datagram carrying an ICMP message to a destination terminal through a socket of an ICMP protocol and the IP address, and setting the maximum hop number which can be forwarded by the IP datagram in a computer network;
and receiving and analyzing the ICMP message returned by each time hop to obtain all intermediate routing addresses from the video conference terminal to the destination terminal.
It should be noted that, when creating a Socket in Socket communication, a parameter protocol of the Socket needs to be set to IPPROTO _ ICMP, which means that an ICMP header is constructed by a program, so as to obtain a Socket of the ICMP protocol.
Preferably, the setting of the maximum hop count that the IP datagram can be forwarded in the computer network specifically includes:
setting the initial value of the time-to-live value TTL of the IP datagram in a computer network to be 0 and the maximum hop number which can be forwarded to be 30.
It should be noted that, when receiving the return information from the t-hop, the receiving function of Socket communication analyzes the information in the carried ICMP message to obtain the IP address at this time, and records it as the intermediate routing address; and the TTL is gradually increased, and when the IP address carried by the return information in a certain jump is monitored as the IP address of the target terminal or the TTL jump number reaches the maximum value, the routing tracking is stopped.

and obtaining packet loss rate data from the video conference terminal to the ith intermediate routing address according to the data volume of the sent ICMP message and the data volume of the ICMP message received by the ith intermediate routing address.
Specifically, the packet loss rate from the video conference terminal to the ith intermediate routing address is calculated according to the following formula:
the data volume of the sent ICMP message is the data volume of the ICMP message sent to the ith intermediate routing address by the video conference terminal, and the data volume of the received ICMP message is the data volume of the ICMP message from the video conference terminal received by the ith intermediate routing address.
It should be noted that, when the video conference terminal sends the ICMP message to the ith intermediate routing address, the receiving end of the intermediate routing address needs to modify the ICMP message and then return to inform the video conference terminal whether to receive the ICMP message.
In a specific embodiment, if the network status monitoring is network delay monitoring, the obtaining of the monitoring data of the network status monitoring based on the ICMP packet transmission condition between the video conference terminal and each intermediate routing address specifically includes:

and obtaining a network delay data set from the video conference terminal to the ith intermediate routing address according to the time stamp when each ICMP message is sent and the time stamp set when the ith intermediate routing address is received.
Preferably, the network latency data set comprises: the network delay time of n ICMP messages sent to the ith intermediate routing address, the maximum network delay time of n ICMP messages sent to the ith intermediate routing address, the minimum network delay time and the average network delay time.
Specifically, the difference between the timestamp when the x-th ICMP packet is sent and the timestamp set when the i-th intermediate routing address is received is used as the network delay time from the video conference terminal to the i-th intermediate routing address of the x-th ICMP packet.
Specifically, the average network delay from the video conference terminal to the ith intermediate routing address is calculated according to the following formula:
wherein n is the data volume of ICMP message sent to the ith intermediate routing address by the video conference terminal and the received timestampxThe timestamp set for the time when the x-th ICMP message is received by the i-th intermediate routing address, and the timestamp sentxIs the time stamp when the x-th ICMP message is sent to the i-th intermediate routing address.
It should be noted that, after the receiving end of each intermediate routing address receives the ICMP message sent by the video conference terminal and confirms that it is correct according to means such as verification, the type of the ICMP message is modified and returned to the video conference terminal, the ICMP message returned by the intermediate routing address is analyzed at the video conference terminal, the timestamp set when the ICMP message is received by the intermediate routing address is obtained, and the network delay time from the video conference terminal to the intermediate routing address can be obtained according to the difference value of the timestamps set at the video conference terminal and the intermediate routing address.
In a specific embodiment, if the network state monitoring is network jitter time monitoring, the obtaining of the monitoring data of the network state monitoring based on the ICMP packet transmission condition between the video conference terminal and each intermediate routing address specifically includes:
sequentially sending n ICMP messages containing time stamps to the ith intermediate routing address through a socket of an ICMP protocol, and recording the time stamp when each ICMP message is sent; wherein n is greater than 1;

and calculating the network jitter time data from the video conference terminal to the ith intermediate routing address according to the maximum network delay time and the minimum network delay time in the n network delay times.
Specifically, a difference value between a maximum network delay time and a minimum network delay time of the n network delay times is calculated as a network jitter time from the video conference terminal to the ith intermediate routing address.
For example, if n ICMP messages are sent to the 2 nd intermediate routing address, the network delay time from n video conference terminals to the 2 nd intermediate routing address is obtained, and the network delay time with the largest value is selected from the n network delay times as the maximum network delay time from the video conference terminal to the 2 nd intermediate routing address; selecting the network delay time with the minimum value from the n network delay times as the minimum network delay time from the video conference terminal to the 2 nd intermediate routing address; and calculating the difference value between the maximum network delay time and the minimum network delay time to obtain the network jitter time from the video conference terminal to the 2 nd intermediate routing address.
In a specific embodiment, if the network status monitoring is line bandwidth monitoring, the obtaining of the monitoring data of the network status monitoring based on the ICMP packet transmission condition between the video conference terminal and each intermediate routing address specifically includes:
