Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
At present, a serpentine self-loop topology traffic testing method is generally used, where a serpentine self-loop topology is shown in fig. 1, fig. 1 takes a 6-port tested network device as an example, a port 1 of a network tester 101 is connected to a port 1 of a tested network device 102, the port 1 of the tested network device 102 is internally communicated with a port 2 of the tested network device 102, the port 2 of the tested network device 102 is externally connected to a port 3 of the tested network device 102 through a network cable, the port 3 of the tested network device 102 is internally communicated with a port 4 of the tested network device 102, the port 4 of the tested network device 102 is externally connected to a port 5 of the tested network device 102 through a network cable, the port 5 of the tested network device 102 is internally communicated with a port 6 of the tested network device 102, and the port 1 of the tested network device 102 is connected to the port 6 of the network tester 101. When the port 1 of the network tester 101 sends a message during the traffic test, the message is forwarded from the port 1 of the network device 102 to the port 6 of the network device 102 via the port 2, the port 3, the port 4, the port 5, and the port 6, and is analyzed at the port 6. If packet loss is found according to the analysis result at the port 6, because the packet passes through all the ports of the network device to be tested, a fault port needs to be diagnosed from all the ports, the diagnosis range is too large, if the number of the ports of the network device to be tested is large, the diagnosis range is very large, the fault port is difficult to be quickly and accurately located, the port fault diagnosis capability is poor, and the maintenance workload is large.
In addition, because the network tester 101 and the network device 102 to be tested are not directly connected to all ports, the clock failure problem cannot be accurately intercepted, that is, it is difficult to find clock related problems such as clock drift.
In order to solve the above technical problems, embodiments of the present application provide a method for testing network port traffic, where a full-port direct-connection loopback topology is adopted, so as to reduce a diagnosis range, facilitate quick diagnosis of a failed port, improve a fault diagnosis performance, and cover fault tests such as clock drift of all ports.

The ports of the network device under test 102 and the ports of the network tester 101 may be directly connected through network cables or optical fibers, respectively.
The multiple ports of the network device under test 102 are sequentially communicated in the network device under test 101 according to a preset sequence, and a first port is communicated with a last port in the preset sequence, so as to form a full-port direct-connection loopback topology.
The preset sequence may be that the ports are connected in sequence according to the arrangement sequence of the ports, for example, the port 1 shown in fig. 2 is communicated with the port 2, the port 2 is communicated with the port 3, the port 3 is communicated with the port 4, the port 4 is communicated with the port 5, the port 5 is communicated with the port 6, and the port 6 is communicated with the port 1; the connection may be in an out-of-order connection, for example, port 1 communicates with port 3, port 3 communicates with port 2, port 2 communicates with port 4, port 4 communicates with port 5, port 5 communicates with port 6, and port 6 communicates with port 1.

s301, the network tester sends a test message to the second port of the tested network equipment through the first port.
The first port is any one port on the network tester, and the first port is correspondingly connected with the second port.
Taking the above-mentioned network device under test as a 6-port device, for example, the network device under test shown in fig. 2. The first port may be port 1, port 2, port 3, port 4, port 5 or port 6 of the network tester. In this embodiment, the first port is the port 1 of the network tester, and the second port is a port connected to the port 1 of the network tester, for example, the port 1 of the network device under test.
S302, the tested network device forwards the tested message to a fourth port of the tested network device through the second port.
Wherein the fourth port communicates with the second port inside the network device under test. Taking fig. 2 as an example, the fourth port is port 2 of the network device under test.
And S303, the tested network equipment sends the test message to the third port of the network tester through the fourth port.
Wherein the third port and the fourth port are correspondingly connected. Taking fig. 2 as an example, the third port is port 2 of the network tester.
And S304, the network tester analyzes the tested message at the third port to obtain an analysis result.
It should be noted that, in this embodiment of the application, using the steps of S301 to S304, the network tester sends a test packet to the port 1 of the network device under test through the port 1, the network device under test forwards the test packet to the port 2 of the network device under test, and then flows to the port 2 of the network tester through the network cable or the optical fiber, and the tester performs packet analysis, statistics, calculation, and the like at the port 2, and provides a corresponding analysis result. Similarly, the network tester sends out a test message through the port 2, the test message passes through the port 2 of the tested network equipment, the port 3 of the tested network equipment and then the port 3 of the network tester, and a test result is obtained after analysis; thus, the other ports make corresponding analysis results according to the policy (finally cover the topology shown in the figure, or test according to the topology scheme customized by the customer, with the topology shown in fig. 2, the flow direction coverage condition of each port of the tested network device is that the port 1 to the port 2, the port 2 to the port 3, the port 3 to the port 4, the port 4 to the port 5, the port 5 to the port 6, and the port 6 to the port 1).
If the analysis result shows that the port of the network device under test has a fault, the network tester analyzes the message under test at the third port in S304, and after obtaining the analysis result, the fault port can be located according to the analysis result.
According to the technical scheme, the plurality of ports of the tested network equipment are connected with the plurality of ports of the network tester in a one-to-one correspondence mode, the plurality of ports of the tested network equipment are sequentially communicated inside the tested network equipment according to the preset sequence, and the first port and the last port in the preset sequence are communicated to form the full-port direct connection loopback topology. When testing, the network tester sends a test message to a second port of the tested network equipment through a first port; the first port is any one port on the network tester, and the first port is correspondingly connected with the second port; the network tester receives the test message sent by a fourth port of the tested network equipment through a third port; the fourth port is communicated with the second port in the interior of the tested network equipment; the third port is correspondingly connected with the fourth port; and the network tester analyzes the tested message at the third port to obtain an analysis result. If the existence of the fault port is determined according to the tested message, the test message only passes through the two ports of the tested network equipment, so that the diagnosis range is reduced under the condition that the number of the ports of the tested network equipment is large, the fault port can be conveniently and quickly diagnosed, the fault diagnosis performance is improved, and the fault tests such as clock drift of all the ports can be covered.
It can be understood that the analysis result in this embodiment may be a packet loss detection result and/or a clock detection result, and whether a test packet is lost in the transmission process may be determined according to the packet loss detection result, so as to determine whether a port through which the test packet passes is faulty, so as to locate a faulty port. In addition, because the ports of the network tester and the tested network equipment are all directly connected, the clock detection result obtained at the ports of the network tester can be used for determining whether clock related problems such as clock drift occur or not, and therefore the problem of clock faults is accurately intercepted.
Optionally, if the analysis result includes a clock detection result, and the test packet includes clock information, at this time, a possible implementation manner of S304 is that the network tester extracts the clock information from the detected packet at the third port; and comparing the clock information with standard clock information to obtain a clock detection result.
Of course, the clock detection result may also be determined according to the packet loss detection result, for example, after determining the packet loss according to the packet loss detection result, there may be many reasons for the packet loss, where clock drift may be a reason for generating the packet loss, so the clock detection result may be further determined according to the packet loss detection result.
