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.

referring to fig. 1, fig. 1 is an interaction schematic diagram of a device testing method according to an embodiment of the present invention, and is applied to a system including a client and a network node.

the network node may be any node in the P2P network that provides shared data resources. Specifically, the physical machine corresponding to the network node may be an edge device such as a computer or a server. The client may be a test software installed on a terminal, the terminal is connected to the network node, and the connection mode may be physical connection, for example, the terminal and the network node may be connected by a data transmission cable; the connection may also be a network connection, for example, the terminal and the network node are connected via the internet.

the specific method of the equipment testing method comprises the following steps:

S101, a client sends a data acquisition request to a network node according to a first sending rate;

s102, the network node responds to the data acquisition request;

S103, the network node sends the data requested by the received data acquisition request to the client;

s104, the network node detects the running state;

s105, the network node sends a rate adjustment request to the client under the condition that the running state is a non-steady state, wherein the non-steady state is as follows: a state that the data acquisition request quantity needing to be responded is not matched with the data processing performance of the network node, wherein the data acquisition request quantity needing to be responded is positively correlated with the first sending rate;

s106, the client adjusts the first sending rate according to the rate adjustment request to obtain a second sending rate, and sends a data acquisition request according to the second sending rate;

s107, when the operation state of the network node is a steady state, obtaining a steady sending rate of the network node sending data to the client side in the steady state, and using the steady sending rate as a test result for testing the data sending performance of the network node, wherein the steady state is as follows: a state in which the amount of data acquisition requests that need to be responded matches the data processing performance.

the operation state is information reflecting the operation condition of the network device, and is related to the data acquisition request quantity to be responded by the network node and the data processing performance of the network node. The data acquisition request amount that the network node needs to respond is the number of data acquisition requests that the network node has received. The data acquisition request quantity is positively correlated with a first sending rate at which the client sends the data acquisition request, and the larger the first sending rate is, the larger the data acquisition request quantity is, the smaller the first sending rate is, and the smaller the data acquisition request quantity is. The data processing performance of the network node is generally determined by the hardware performance of the network node, wherein the hardware performance includes the memory, the CPU frequency, and the like of the network node.

Specifically, when the performance of sending data by the network node is tested, the client may send a data obtaining request to the network node. The data obtaining request is used for requesting to obtain data stored in a network node, where the data may be all data stored in the network node or a part of data openly shared in the network node. The data obtaining request carries data information of a request instruction and data expected to be requested, and the data information can be a data name, a data identifier, a data storage position and the like. Each data acquisition request may be for requesting one or more of the data stored by the network node.

after receiving a data acquisition request sent by a client, a network node processes the received request, and the data acquisition request amount that the network node can respond to in unit time is related to the data processing performance of the network node, that is, the data processing performance of the network node can be measured by the data acquisition request amount that the network node can respond to in unit time.

When the amount of data acquisition requests received by the network node in unit time is large, a situation that the data acquisition requests are queued may occur in one situation, and further the data acquisition requests cannot be responded to in time. Another situation may arise where there are fewer resources available to respond to each data fetch request, resulting in a slow response to each data fetch request. In any case, it is shown that the amount of data acquisition requests that the network node needs to respond to exceeds its own data processing performance, that is, the amount of data acquisition requests that need to respond does not match its own data processing performance.

when the amount of the data acquisition request received by the network node in unit time is small, a large amount of resources of the network node are idle, which obviously means that the amount of the data acquisition request to be responded by the network node is lower than the data processing performance of the network node, and the amount of the data acquisition request to be responded is not matched with the data processing performance of the network node.

Under the two conditions, the data acquisition request quantity to be responded by the network node is not matched with the data processing performance of the network node, and the data acquisition request quantity to be responded by the network node needs to be continuously adjusted in order to ensure that the network node can normally operate.

in the case where the amount of the data acquisition request requiring response matches the data processing performance of the network node, the operation state of the network node may be referred to as a stationary state, corresponding to the non-stationary state.

that is, the operation state of the network node may be divided into a stationary state and a non-stationary state. The non-stationary state may further include an underload state and an overload state, because the non-stationary state may be caused by the amount of data acquisition requests that the network node needs to respond to exceeding its own data processing performance, and may be caused by the amount of data acquisition requests that the network node needs to respond to being lower than its own data processing performance.

In view of the above, in one embodiment of the present invention, the various states referred to above, from the perspective of standing per unit time, can be understood in light of the following description.

The above-mentioned steady state can be understood as: the data acquisition request quantity received in unit time of the network node is matched with the data processing performance of the network node.

The above-mentioned non-stationary state can be understood as: and the state that the data acquisition request quantity received in the unit time of the network node is not matched with the data processing performance of the network node.

the overload state can be understood as: the data acquisition request quantity received in unit time by the network node exceeds the data processing performance of the network node.

the above-mentioned underrun condition can be understood as: the data acquisition request quantity received in unit time by the network node is lower than the data processing performance of the network node.

under the condition that the running state of the network node is a stable state, the stable sending rate of the data sent by the network node to the client is obtained and used as a test result for performing performance test on the network node, and thus the obtained test result can truly reflect the optimal performance of the network node.

and because the maximum rate of the data sent by the network node can represent the optimal performance of the network node, the stable sending rate is used as a test result for testing the data sending performance of the network node, and the performance of the network node can be truly and accurately reflected. Therefore, the scheme provided by the embodiment of the invention can be used for testing the performance of the data sent by the network node.

Referring to fig. 2, fig. 2 is a schematic flowchart of a first device testing method provided in the embodiment of the present invention, and is applied to a network node.

S201, receiving a data acquisition request sent by a client according to a first sending rate, sending data requested by the received data acquisition request to the client, and detecting the running state of a network node.

in an embodiment of the present invention, a terminal for installing a client and a network node first establish a communication connection, and specifically, the communication connection may be established based on a TCP (Transmission Control Protocol) or a UDP (User Datagram Protocol), which is not limited in the embodiments of the present invention.

In one embodiment of the invention, the network node is in the same local area network as the terminal where the client is installed. The local area network is a closed network, and data is transmitted in the local area network with strong stability, high reliability and high transmission rate.

the client receives an Internet Protocol (IP) Address of a network node which is expected to perform a device test and a port number of the network node, which are input by a user. Therefore, the client can directionally send the data acquisition request to the network node which is expected to carry out the equipment test according to the IP and the port number of the network node.

after receiving a data acquisition request sent by a client, a network node determines data requested by the data acquisition request from data stored in the network node, sends the determined data to the client, and detects an operating state in a process of processing the data acquisition request by the network node.

In an embodiment of the present invention, a ratio of non-timeout data in the sent data to the sent data may be detected, and the operation state of the network node may be obtained according to the ratio.

Wherein, the non-overtime data is: the time interval between the data sending time and the time of receiving the data request is less than a first preset time length, where the first preset time length may be 10 milliseconds, 50 milliseconds, 100 milliseconds, and the like, and the embodiment of the present invention does not limit this. For example, for a data acquisition request, the time when the network node obtains the request is 0 ms, the time when the data requested by the request is sent to the client is 30 ms, and the first preset time duration is 50 ms, since the time interval between the sending time of the data and the time when the data request is received is 30 ms, which is smaller than the first preset time duration, the data requested by the request is non-timeout data.

specifically, the ratio of the non-overtime data in the data sent by the network node to the sent data may be detected within a preset time period before the current time, or the ratio of the non-overtime data in a preset number of data sent by the network node before the current time to the sent data may be detected.

For example, it is detected that 100 pieces of data are sent by the network node within a preset time period before the current time, where 80 pieces of non-timeout data are detected, and the ratio of the non-timeout data to the sent data is 80%.

The ratio of the non-overtime data to the sent data can directly reflect the operation state of the network node, and when the operation state of the network node is good, the network node can send out the data in time, so that the ratio of the non-overtime data to the sent data is large; on the contrary, when the network node is in a poor operation state, the network node cannot send out the data in time, which may cause task accumulation, and the proportion of the data which is sent out overtime will be larger and larger, that is, the proportion of the data which is not overtime will be smaller and smaller. By detecting the ratio of the non-overtime data, the operation state of the network node can be accurately obtained.

in an embodiment of the present invention, after detecting a ratio of non-overtime data in transmitted data to the transmitted data, in a case that the ratio is greater than a preset upper threshold, it indicates that a data acquisition request amount that a network node needs to respond is lower than its own data processing performance, and therefore, it may be considered that an operating state of the network node is an underloaded state; under the condition that the ratio is smaller than the preset lower limit threshold, it is indicated that the data acquisition request quantity to be responded by the network node exceeds the data processing performance of the network node, so that the operation state of the network node can be considered as an overload state; in the case that the above ratio is between the upper threshold and the lower threshold, it means that the data acquisition request amount to which the network node needs to respond matches the data processing performance of the network node itself, and therefore the operation state of the network node can be considered to be a steady state.

Wherein the upper threshold is greater than the lower threshold. The specific values of the upper threshold and the lower threshold can be obtained according to application scenarios and empirical values. By adjusting the upper threshold and the lower threshold, the judgment condition of the network node operation state can be limited according to the requirement. When the precision of the upper limit threshold and the lower limit threshold is higher, the judgment on the running state of the network node is more accurate, and the accuracy of the obtained performance test result is higher.

Under the condition that the network node is in an underload state or an overload state, the task amount received by the network node in unit time is not matched with the data processing performance of the network node, and therefore the network node can be considered to be in a non-steady state.

The following is a description by way of specific examples. If the calculated ratio is 90% and is greater than the upper threshold 80%, it is assumed that the upper threshold is 80% and the lower threshold is 40%, which indicates that the data acquisition request amount that the network node needs to respond to is lower than the data processing performance of the network node itself, and therefore the operation state of the network node may be considered as an underload state; if the calculated ratio is 20% and is less than the lower threshold 40%, it indicates that the data acquisition request amount that the network node needs to respond exceeds the data processing performance of the network node itself, and therefore the operation state of the network node can be considered as an overload state; if the calculated ratio is 60% and is between the upper threshold 80% and the lower threshold 40%, it indicates that the data acquisition request amount to which the network node needs to respond matches with its own data processing performance, and therefore the network node may be considered to be in a steady state.

on the basis of the above embodiment, in an embodiment of the present invention, the operation state of the network node may also be determined according to a duration that the above ratio is within the threshold range. Wherein, the threshold range is: a range from a lower threshold to an upper threshold.

specifically, when the duration of which the ratio is within the threshold reaches the duration threshold, it is determined that the task amount received by the network node in unit time matches the data processing performance of the network node, and the operating state of the network node is considered to be a steady state, otherwise, it is determined that the task amount received by the network node in unit time does not match the data processing performance of the network node, and the operating state of the network node is considered to be a non-steady state. The duration threshold value can be obtained according to an application scene and a preliminary experiment.

In an embodiment of the present invention, a test duration between the current time and the time when the data acquisition request is received for the first time may also be detected, and the operation state of the network node may be obtained according to the test duration.

the network node starts to respond to the received request and detects the running state of the network node from the moment when the network node receives the data acquisition request for the first time, and sends a rate adjustment request to the client under the condition that the running state of the network node is in a non-steady state until the running state of the network node is in a steady state. That is, the rate at which the client sends the data acquisition request to the network node is continuously adjusted, and then the data acquisition request amount that the network node needs to respond is continuously adjusted, based on which, it can be considered that the data acquisition request amount that the network node needs to respond matches the data processing performance of the network node itself after a certain time period has elapsed since the network node first received the data acquisition request, and then it can be considered that the network node has finished adjusting the sending rate of the data acquisition request to the client, that is, the network node is in a stable state. Therefore, the running state of the network node is judged by detecting the test duration, the network node does not need to perform complex calculation, the performance resources of the network node can be saved, and the network node can better respond to the data acquisition request.

In one embodiment of the invention, after the test duration is obtained, when the test duration reaches a second preset duration, the client is considered to finish adjusting the first sending rate, and the data acquisition request quantity to be responded by the network node is matched with the data processing performance of the network node, so that the operation state of the network node is a stable state; under the condition that the test time length does not reach the second preset time length, the client is considered to have not adjusted the first sending rate, and the data acquisition request quantity to be responded by the network node is not matched with the data processing performance of the network node, so that the operation state of the network node is obtained to be a non-steady state.

the second preset time period may be 3 minutes, 5 minutes, 1 minute, and the like, and the specific value may be obtained according to an application scenario and an empirical value. Therefore, the time required by the test can be controlled by limiting the second preset time, when the second preset time is longer, the obtained running state of the network node is more accurate in a stable state, and when the second preset time is shorter, the time required by the equipment test is shorter, so that the test efficiency can be accelerated.

s202, sending a rate adjustment request to the client under the condition that the running state is a non-steady state.

under the condition that the operation state is a non-steady state, it is described that the data acquisition request quantity to be responded by the network node is not matched with the data processing performance of the network node, and therefore, the rate at which the client sends data to the network node to obtain the request needs to be adjusted, so that the data acquisition request quantity to be responded by the network node is matched with the data processing performance of the network node, and the network node can send a rate adjustment request to the client based on the rate adjustment request. And after receiving the rate adjustment request, the client adjusts the rate of sending the data acquisition request.

Referring to fig. 3, fig. 3 is a schematic flow chart of a second device testing method according to an embodiment of the present invention, where after receiving a rate adjustment request sent by a network node, a client adjusts the first sending rate to obtain a second sending rate, and continues to send a data acquisition request at the adjusted second sending rate. The network node needs to return to execute step S201, receive a data acquisition request sent by the client, send the requested data to the client, and detect the operating state of the network node.

in one embodiment of the invention, the non-steady state comprises an underload state and an overload state, and the speed down-regulation request is sent to the client terminal under the condition that the running state is the overload state, and the speed up-regulation request is sent to the client terminal under the condition that the running state is the underload state.

The rate down-regulation request is used for requesting the client to down-regulate the rate of sending the data acquisition request, and the rate up-regulation request is used for requesting the client to up-regulate the rate of sending the data acquisition request.

Under the condition that the operation state of the network node is an overload state, the data acquisition request amount required to be responded by the network node exceeds the data processing performance of the network node, and the data acquisition request amount received by the network node in unit time is related to the rate of sending the data acquisition request by the client, so that a rate down-regulation request needs to be sent to the client, and after the client receives the rate down-regulation request, the sending rate of the currently sent data acquisition request can be down-regulated, so that the rate is reduced when the client continuously sends the data acquisition request to the network node, namely, the data acquisition request amount received by the network node in unit time is reduced, and the data acquisition request amount required to be responded by the network node is reduced.

under the condition that the running state of the network node is an underload state, it is described that the data acquisition request amount required to be responded by the network node is lower than the data processing performance of the network node, and the data acquisition request amount received by the network node in unit time is related to the rate of sending the data acquisition request by the client, so that a rate up-regulation request needs to be sent to the client, and after receiving the rate up-regulation request, the client can up-regulate the sending rate of the currently sent data acquisition request, so that the rate of the client continuously sending the data acquisition request to the network node is reduced, that is, the data acquisition request amount sent to the network node in unit time is reduced, thereby being beneficial to reducing the data acquisition request amount required to be responded by the network node.

by sending the rate up-regulation request or the rate down-regulation request to the client, the client regulates the rate in a targeted manner according to the received rate up-regulation request or the received rate down-regulation request, so that the data acquisition request quantity required to be responded by the network node can be regulated, the running state of the network node can be further regulated, and finally, the network node can reach a stable state.

S203, under the condition that the operation state is a stable state, obtaining the stable sending rate of the data sent by the network node to the client under the stable state, and taking the stable sending rate as a test result for testing the data sending performance of the network node.

under the condition that the operation state of the network node is a stable state, the data acquisition request quantity required to be responded by the network node is matched with the data processing performance of the network node, and the data acquisition request sending rate of the client and the data sending rate of the network node reach a balanced state.

In an embodiment of the present invention, a rate at which the network node sends data to the client within a third preset duration in a steady state may be obtained as a steady sending rate.

specifically, the data sending rate of the network node is fluctuating, and by obtaining the data sending rate of the network node within a period of time, the interference of the peak value or the trough value of the data sending rate of the network node can be eliminated, so that the obtained stable sending rate can reflect the performance of the network node more truly.

in an embodiment of the present invention, a rate at which the network node sends data to the client within a preset third duration may be obtained according to a preset time interval, and an average value of the obtained multiple rates is calculated to be used as a sending rate at which the network node sends data to the client.

for example, the preset time interval may be 10 seconds, the third duration may be 1 minute, the rate at which the network node sends data to the client within 1 minute is obtained every 10 seconds, 7 rates are obtained in total, and an average value of the 7 rates is calculated as the sending rate at which the network node sends data to the client.

in an embodiment of the present invention, the data amount of data sent by the network node to the client within a third preset time period in a steady state may also be counted, and an average sending rate of the network node within the third preset time period is calculated according to the data amount and the third preset time period, and is used as the steady sending rate.

It should be noted that there is no execution sequence for the above steps S202 and S203, and the execution of S202 and S203 depends only on the result of the operation state detected in S201.

in an embodiment of the present invention, after obtaining the test result, the network node may further send the test result to the client. Therefore, the client can conveniently display the test result, and the user can conveniently obtain the test result.

As can be seen from the above technical solutions, when the device testing scheme provided by the embodiments of the present invention is applied to perform a performance test on a network node, the network node receives a data acquisition request sent by a client at a first sending rate, sends data requested by the received data acquisition request to the client, and detects an operating state of the network node; under the condition that the operation state is a non-steady state, the data acquisition request quantity required to be responded by the network node is not matched with the data processing performance of the network node, so that a rate adjustment request is sent to the client, the first sending rate is adjusted by the client to realize the adjustment of the data acquisition request quantity, under the condition that the operation state is a steady state, the data acquisition request quantity required to be responded by the network node is matched with the data processing performance of the network node, and the obtained steady sending rate of the data sent to the client by the network node is close to the maximum rate of the data sent by the network node.

specifically, the data obtaining request template includes an instruction template and a data information template, and the data information template is replaced with the data information of the obtained data to be requested, so as to generate a data obtaining request. Therefore, a user does not need to manually input a data acquisition request, and the efficiency of the performance test of the equipment is improved.

in an embodiment of the present invention, a manually input data acquisition request template may be directly obtained, or a data acquisition request template may be generated according to a data acquisition request stored in a data acquisition request log. Specifically, when the network node uploads data, a data acquisition request log is generated, the data acquisition request actually received by the network node is stored in the log, and a data acquisition request template is obtained according to the actually received data acquisition request. The data obtaining request log may be a log generated during a network peak period of the network node, for example, the network peak period may be 20: 00-22:00.

In an embodiment of the present invention, when the first sending rate is adjusted to obtain the second sending rate, the first sending rate may be adjusted according to a preset ratio. Wherein the preset ratio may be 10%, 5%, 20%, etc.

for example, assuming that the preset ratio is 10%, the first transmission rate is 10Mbps, and in the case of up-regulating the first transmission rate, the second transmission rate is

10Mbps*(1+10％)＝11Mbps

In another embodiment of the present invention, when the first sending rate is adjusted to obtain the second sending rate, the adjustment may be performed according to a preset difference. Wherein, the preset difference value can be 0.1Mbps, 0.2Mbps, 0.05Mbps, etc.
