Fig. 1 is a flowchart of a fault locating method of a binding port of a network device according to an embodiment of the present invention, where, as shown in fig. 1, the method includes:
102, comparing a variation coefficient of each binding port at the current moment with a historical baseline variation coefficient to determine the binding port with a fault at the current moment, wherein the historical baseline variation coefficient of each binding port is obtained according to a plurality of historical variation coefficients of each binding port;
In the embodiment of the invention, the binding port with the fault at the current moment is determined by comparing the variation coefficient of each binding port at the current moment with the historical baseline variation coefficient, and the historical baseline variation coefficient is obtained in advance, so that the process for determining the binding port with the fault at the current moment is simple and high in efficiency, the subsequent binding port with the fault at the current moment can directly determine the member port with the fault at the current moment according to the bandwidth utilization rate of each member port in the binding ports with the fault, and compared with the traditional modeling process, the previous process is simple and does not depend on the business knowledge of network experts, and is easy to realize and high in efficiency.
In specific implementation, the network device refers to a physical entity forming a network of a telecom operator, and mainly comprises a switch, a broadband remote access server, a router and the like. Modern telecommunications carrier networks consist of thousands of network devices. Fig. 2 is a schematic diagram of a binding port in an embodiment of the present invention, where a network device may have a plurality of binding ports, and each binding port has a plurality of member ports, and because of the data volume of the network device in the backbone network of the telecom operator, the number of binding ports is large, the bandwidth is large, and a large amount of user services are carried. Once a problem arises, the effect is great. Based on the principle of 'no disorder and no trouble', when the problem starts to appear at the beginning, sensitive and effective early warning is required to be provided, and the member port with the problem is rapidly positioned so as to solve the problem early. The inventors have found that under normal circumstances, the bandwidth utilization of the individual member ports is approximately the same due to the traffic sharing mechanism of the network device. Once the bandwidth utilization of the member ports deviates greatly, this means that a problem occurs in a certain member port, and the router device, for example, has automatically switched the traffic carried by the member port with the problem to other member ports.
In an embodiment, before obtaining the coefficient of variation of the current time of each bonded port according to the bandwidth utilization of the plurality of member ports of each bonded port of the network device at the current time, the method further includes:
for each binding port of the network device, obtaining the flow rate and bandwidth of each member port of the binding port at the current moment;
and obtaining the bandwidth utilization rate of each member port at the current moment according to the flow rates and the bandwidths of the plurality of member ports of the binding port at the current moment.
In the above embodiment, the flow rate of each member port is the inflow or outflow rate, and the flow rate of the member port at the present moment is collected, and typically, the flow rate is collected at regular intervals, for example, every 5 minutes. The process for calculating the bandwidth utilization rate not only considers the bandwidth, but also considers the flow rate of the member port, and the calculated bandwidth utilization rate has higher accuracy.
In an embodiment, according to the bandwidth utilization of a plurality of member ports of each binding port of the network device at the current time, the following formula is adopted to obtain the variation coefficient of each binding port at the current time:
wherein r is i Bandwidth utilization for the ith member port of each bonded port;
n is the total number of member ports per bonded port.
In the above embodiment, the variation coefficient is used to determine whether the bundled port transmits a fault at the current moment, which reflects the equalization degree of the bandwidth utilization rate of the member port. Through calculating the coefficient of variation in real time, hidden danger can be effectively found sensitively, and early warning is provided. In probability theory and statistics, the coefficient of variation is a normalized measure of the degree of dispersion of the probability distribution. Fig. 3 is a schematic diagram of a variation coefficient of a binding port at multiple times in the embodiment of the present invention, as shown in fig. 3, the binding port is composed of 7 member ports, and when the average bandwidth utilization rate of the 7 member ports is very small, the variation coefficient is very unstable, so in step 101, the current time needs to be determined from busy time periods of the multiple binding ports, so that a small disturbance of the bandwidth utilization rate of the member ports will not cause a severe change of the variation coefficient, thereby avoiding a false report situation as much as possible. The busy hour period may be, for example, 9 early to 11 late.
In one embodiment, the historical baseline coefficient of variation for each bonded port is obtained using the following formula:
wherein C is t Historical baseline coefficients of variation for each binding port;
c i,t historical variation coefficients at time t of the ith day for each binding port;
n is the total number of days.
In the above embodiment, each binding port has its own historical baseline variation coefficient, and since the bandwidth utilization of the member ports is different at each time, a variation coefficient can be obtained at each time, so in order to make the historical baseline variation coefficient meaningful, it is necessary to count the historical variation coefficient at each time every day, and the greater the total number of days, the more accurate the historical baseline variation coefficient. The time of day may be accurate to a minute, for example 9 points 15 minutes.
In an embodiment, comparing the variation coefficient of the current time of each binding port with the historical baseline variation coefficient to determine the binding port with the fault at the current time comprises:
obtaining a historical baseline variation coefficient of the current moment of each binding port;
for each binding port, when the difference value between the variation coefficient of the current moment of the binding port and the historical baseline variation coefficient of the current moment exceeds a set threshold value, determining that the binding port fails at the current moment.
In the above embodiment, the predetermined historical baseline variation coefficient of the current time of each binding port may be obtained through the formula (4), the above set threshold may be determined according to the actual situation, and the above process of determining the binding port that fails at the current time is very simple, and only the variation coefficient of the binding port at the current time is compared with the historical baseline variation coefficient at the current time, which is very efficient compared with the conventional modeling method. Fig. 4 is a schematic diagram of a variation coefficient of another binding port at a plurality of moments in an embodiment of the present invention, as shown in fig. 4, the variation coefficient is abrupt at a moment 201908061500, which illustrates that the binding port fails at a moment 201908061500. Through investigation, at the moment 201908061500, the traffic of one member port of the bonded port is 0, and the member port fails, which indicates that the bonded port determined by the method of the variation coefficient is accurate.
In specific implementation, there are various methods for determining each failed binding port at the current time according to the bandwidth utilization of each member port in the failed binding port, and one embodiment is given below.
In one embodiment, determining, for each failed bonded port at the current time, the failed member port at the current time based on the bandwidth utilization of each member port in the failed bonded port includes:
obtaining an average value of bandwidth utilization rates of a plurality of member ports in the failed bonded port;
calculating the difference between the bandwidth utilization rate of each member port and the average value;
and determining the member port with the largest difference value as the member port with the fault at the current moment.
In the above embodiment, the average value of the bandwidth utilization ratios of the plurality of member ports in the failed binding port is obtained, and may be calculated by the formula (4), and the previous step is actually performed, where data may be directly obtained in this step, the difference value between the bandwidth utilization ratio of each member port and the average value is calculated, the absolute value of the difference value is generally obtained, the member port with the largest difference value is determined to be the member port with the failure at the current moment, in some cases, there may be a failure in the plurality of member ports with the difference value exceeding the preset difference value threshold, and the related variation cases should all fall into the protection scope of the present invention.
In an embodiment, the method further comprises:
and generating early warning information of the member port which is faulty at the current moment.
The early warning information can be prompted through interfaces, sounds and the like.

Of course, it can be understood that other variations of the detailed flow of the fault locating method of the binding port of the network device are also possible, and all related variations should fall within the protection scope of the present invention.
