First, application scenarios applicable to the present application will be described. The method and the device can be applied to throughput testing of the Ethernet data carried by the video networking.
Based on the above, the embodiment of the application provides a method and a system for throughput testing.
Referring to fig. 1 and fig. 2, fig. 1 is a flowchart of a throughput testing method according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a throughput testing system according to an embodiment of the present application. As shown in fig. 1 and fig. 2, the throughput testing system provided in the embodiments of the present application includes a view networking terminal and a view networking server, where the view networking terminal at least includes an ethernet interface, a protocol conversion module and a view networking interface that are sequentially connected, the ethernet interface of the first view networking terminal is used for being connected with a first network interface of a testing device, and the ethernet interface of the second view networking terminal is used for being connected with a second network interface of the testing device. The video networking interface of the first video networking terminal is used for being connected with the first network interface of the video networking server, and the video networking interface of the second video networking terminal is used for being connected with the second network interface of the video networking server.
The view port terminal may be a view router. The video router has at least an Ethernet interface Ge0/1 and a video network interface Ge0/8. The video router is also provided with a protocol conversion module used for converting Ethernet data and video networking data.
The test device is a portable, visual, intelligent detection device that can detect the physical layer, data link layer, network layer operating conditions defined by the OSI model. The method is used for performing performance test on the network equipment and checking parameters such as throughput, delay and bandwidth of the equipment. The test equipment has at least ethernet interfaces Ge1/1 and Ge1/2 for transmitting or receiving ethernet data.
The architecture of throughput test can be as shown in fig. 2, where a first video terminal and a second video terminal are deployed in a video networking environment respectively, and are connected with test equipment to form a data transmission loop. The Ethernet interface of the first video terminal is connected with the first Ethernet interface of the test equipment through a network cable, and the Ethernet interface of the second video terminal is connected with the second Ethernet interface of the test equipment through a network cable. The video networking interface of the first video networking terminal is connected with the first network interface of the video networking server through an optical module, and the video networking interface of the second video networking terminal is connected with the second network interface of the video networking server through an optical module.
Before testing, the first video terminal and the second video terminal are required to be respectively registered into the video network, and the video network number is opened and configured to access the network. And automatically establishing a visual networking VPN tunnel between the first visual networking terminal and the second visual networking terminal. And carrying out data transmission in the VPN tunnel through the VPN server.
Then, logging in the test equipment, connecting the Ethernet interfaces Ge1/1 and Ge1/2 corresponding to the test equipment, selecting the corresponding test templates, setting the corresponding parameters, and confirming the start of the test. Next, the testing step includes:
s101, the test equipment responds to a throughput test instruction and sends a first test data packet to the first video terminal through an Ethernet transmission channel.
The throughput test instruction is used for indicating parameters such as test rounds, single-round test time, test precision, data packet size, data packet quantity and the like.
S102, the first video terminal converts the received first test data packet into a second test data packet and sends the second test data packet to the second video terminal through a video networking transmission channel.
S103, the second video networking terminal converts the received second test data packet into a third test data packet and sends the third test data packet to the test equipment through the Ethernet transmission channel, so that the test equipment determines the throughput of the video networking transmission channel.
According to the throughput testing system provided by the embodiment of the application, the throughput of the visual network core server can be determined by constructing the testing equipment and the data transmission loop between the visual network terminals and performing throughput testing. Compared with the prior art that the PC is adopted to run the test software, the requirements of the client market are met, and the throughput test result is more accurate and standard.
In particular, the test run may be one or more times. In order to obtain more accurate test results, multiple rounds of testing are typically performed.
And in the single-round test time, the test equipment sends a first test data packet with a first preset number to the first video terminal based on the preset rate so as to acquire a third test data packet with a second preset number fed back by the second video terminal, and the preset rate in the next round of test is adjusted according to the deviation between the first preset number and the second preset number.
The test equipment can adjust the preset rate in the next round of test in the following way: and comparing the magnitudes of the first preset number and the second preset number in the single-round test time. When the first preset number is equal to the second preset number, the preset speed of the next round of testing is increased. And when the first preset number is larger than the second preset number, reducing the preset speed in the next round of test.
Taking the first round of testing as an example, parameters such as the preset rate, the single round of testing time, the size of the data packets, the number of the data packets and the like are preset by a technician before testing, and the testing equipment sends the data packets to the first video terminal through the Ge1/1 interface according to a certain time interval and an initial rate. The packet size may be 64 bytes, 128 bytes, 256 bytes, 512 bytes, 1024 bytes, 1446 bytes, 1518 bytes, etc.
The first video networking terminal receives a first test data packet in an Ethernet format through a Ge0/1 interface and converts the first test data packet into a second test data packet in a video networking format through a protocol conversion model. The first video terminal uploads the second test data packet to the video networking server through the Ge0/8 interface, and the video networking server forwards the second test data packet to the Ge0/8 interface of the second video terminal.
And the second video terminal converts the received second test data packet in the video networking format into a third test data packet in the Ethernet format, and sends the third test data packet back to the Ge1/2 interface of the test equipment through the Ge0/1 interface.
The test device can count the second preset number of the received test data packets in the first round of test time, compare the second preset number with the first preset number actually sent, and determine whether to drop the packets.
If the first preset number is equal to the second preset number, no packet is lost, and at this time, the preset rate in the next round of test can be increased. If the first preset number is greater than the second preset number, packet loss is indicated, and the preset rate of the next round of test is required to be reduced. Taking the initial rate (1000M) as 50% for example, the second round of testing requires an increase in rate, then adjust to 75%, the third round of testing requires a decrease in rate, then adjust to 62.5%, and so on.
As shown in fig. 3, the test device may then determine the throughput of the internet of view transmission channel by:
s201, determining a speed difference value between a first preset speed and a second preset speed corresponding to two adjacent rounds of testing.
S202, determining whether the rate difference value is smaller than the product between the test precision and the initial rate.
And S203, if yes, recording the current preset rate and taking the current preset rate as the throughput of the video networking transmission channel.
S204, if not, carrying out the next round of test, and returning to the step S201.
For example, the rate difference between the preset rates in the first test round and the second test round is calculated, and if the rate difference is smaller than 1000m×1%, the current preset rate can be recorded and used as the throughput of the video network transmission channel. If the test precision requirement is not met, the next round of test is carried out after the preset speed is adjusted until the test precision requirement is met, and the test can be stopped. Or after the number of tests is satisfied, the test may be stopped.
In a specific embodiment, the test may be stopped and the result output when a throughput is determined, thus saving time. The throughput here is determined based on the RFC2544 protocol, measured in terms of the maximum number of packets per second passed (PPS/FPS) or bits (bits/s, KBbit/s, mbit/s, gbit/s, etc.).
The test may also be stopped after the number of tests is met, where multiple throughput results may be determined, and the average rate may be calculated based on all recorded preset rates. And taking the average rate as the throughput of the video networking transmission channel. The accuracy of the results obtained in this way is higher.
In the foregoing embodiment, the provided testing method adopts unidirectional testing, that is, the test data packet is sequentially sent to the first view router, the view server, and the second view router and then returns to the testing device. In one embodiment of the present application, a bidirectional test manner may also be adopted, that is, the test device sends the test data packet to the first view router and the second view router at the same time. At the moment, the first visual connection router sends the received test data packet to the second visual connection router through the visual connection server, the second visual connection router sends the test data packet back to the test equipment, meanwhile, the second visual connection router also sends the test data packet sent by the test equipment to the first visual connection router through the visual connection server, and the first visual connection router feeds back the received test data packet to the test equipment.
In this case, the process and principle of the test device outputting the test result are similar to those of the foregoing embodiment, and will not be described again. The bidirectional test mode has higher performance requirement on the video networking, the obtained data is more convincing, and the test time is faster.
In one embodiment of the application, the view networking terminal may be a view networking router, so as to balance the memory resource allocation and reduce the resource occupation, whether the view networking transmission channel between the first view networking router and the second view networking router is successfully established or not may be determined, if yes, the protocol conversion module is invoked, otherwise, the corresponding thread is set to an ending or suspension state, so as to reduce the thread occupation.
