Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for measuring network parameters provided by the present application can be applied to the application environment shown in fig. 1, in which a client, a measurement device, and a server are connected to each other through a network. Specifically, the network connection may be a wired network connection or a wireless network connection. The client may be but not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, the measuring device is used for measuring network performance of a network between the client and the server, and may be but not limited to various measuring devices, apparatuses, systems and the like, and the server may be implemented by an independent server or a server cluster formed by a plurality of servers.
The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart of a method for measuring a network parameter according to an embodiment. The implementation is mainly performed by the measurement device in fig. 1, and this embodiment relates to a specific process in which the measurement device configures a network by measuring an actual performance parameter of the network and further by using a measured result. As shown in fig. 2, the method includes:
s101, monitoring the change trend of the transmission rate of the network.
The variation trend is used to indicate the variation of the transmission rate of the network at different monitoring time points, and may be a trend of increasing the transmission rate or a trend of decreasing the transmission rate. It should be noted that, assuming that the above-mentioned trend is a transmission rate decrease, that is, when the transmission rate between the server and the client decreases, the measurement device may implement the transmission rate decrease by controlling the transmission time of the message between the server and the client, for example, the measurement device may receive the message sent from the client to the server, and resend the message to the server after a certain time, so as to generate a certain time delay between the server and the client, thereby changing the transmission rate. In this embodiment, when the method is applied to the application scenario shown in fig. 1, when the measurement device measures the actual network performance of the network between the client and the server, the change trend of the transmission rate of the network may be monitored in real time, and optionally, the measurement device may also periodically monitor the change trend of the transmission rate of the network, so that the measurement device may measure the network parameter according to the change trend.
S102, when the change trend has a mutation point with a reduced rate, determining the maximum transmission rate of the network according to the mutation point with the reduced rate on the change trend.
Wherein, the maximum transmission rate represents the maximum transmission rate limit value that the network can bear. In practical application, when the measurement device monitors that a sudden point with a reduced rate appears on a change trend, it indicates that the transmission rate in the network has changed greatly, and the transmission rate may exceed the maximum transmission rate limit value that can be borne by the network, so the transmission rate monitored by the measurement device at the sudden point is the maximum transmission rate of the network, which is equivalent to the maximum transmission rate limit value that can be borne by the network. In this embodiment, when the measurement device measures the transmission performance of the network, the measurement device may determine the maximum transmission rate that can be borne by the network in practical application directly according to a sudden point of rate reduction on a change trend.
S103, acquiring network parameters according to the maximum transmission rate and the network time delay corresponding to the mutation point.
The network parameter is used to represent the transmission performance of the network, and may be any parameter capable of representing the transmission performance of the network, for example, a throughput of network transmission, a bandwidth, a transmission rate, a transmission delay, a bandwidth-delay product, and the like. The network latency (RTT) represents the delay Time for communications back and forth between the client and the server.
In this embodiment, the measurement device may further record the network delay between the client and the server at this time while determining the maximum transmission rate of the network according to the monitored variation trend of the transmission rate, determine the recorded network delay as the network delay corresponding to the mutation point, and then obtain the performance parameter of the network according to the maximum transmission rate of the network and the network delay corresponding to the mutation point. Optionally, the measurement device may calculate the maximum transmission rate and the network delay corresponding to the mutation point, and then obtain the required network performance parameter therefrom.
And S104, configuring the network according to the network parameters and the service quality parameters matched with the network parameters.
The Quality of Service (QoS) parameter refers to a network that can provide better Service capability for specified network communication by using various basic technologies, is a security mechanism of the network, and is a technology for solving problems such as network delay and congestion, and may specifically include parameters such as Committed Information Rate (CIR), Peak Information Rate (Peak Information Rate, PIR), and the like. In this embodiment, after the measurement device obtains the network parameter of the network by monitoring the variation trend of the transmission rate of the network, the measurement device may further instruct the user to select the qos parameter matched with the network parameter according to the network parameter, and perform hardware or software configuration of each switching device on the preconfigured network according to each technical index included in the qos parameter, so that the network performance of the configured network is matched with the network performance constrained by the qos parameter. Optionally, after acquiring the network parameter of the network, the measurement device may also directly instruct the user to perform hardware or software configuration on each switching device in the network on the preconfigured network according to the network parameter.
In the method for measuring network parameters provided in the above embodiment, the measurement device obtains the mutation point by monitoring a variation trend of the transmission rate of the network, determines the maximum transmission rate of the network according to the mutation point, further determines the network parameters by combining the network delay corresponding to the mutation point, and then configures the network according to the network parameters and the service quality parameters matched therewith. In the method, the measuring equipment obtains the transmission rate mutation point by analyzing the variation trend of the transmission rate of the network so as to obtain the network parameter, and the network parameter obtained by measurement is closer to the actual performance parameter of the network because the transmission rate mutation point corresponds to the limit value of the actual transmission rate which can be carried by the network. Therefore, according to the network configured by the network parameters and the matched service quality parameters, the actual application performance of the network is basically consistent with the network performance constrained by the service quality parameters of the network, the network data packet loss, congestion and delay are avoided, and the normal speed transmission of the network is greatly ensured.
In an application scenario, optionally, the network parameters involved in the foregoing embodiments may include a maximum transmission rate, a network delay, and a bandwidth-delay product.
The maximum transmission rate represents a maximum transmission rate limit value that can be carried by a network in practical application, and belongs to a bottleneck performance parameter of the network. Network latency represents the latency of communications back and forth between a client and a server. The bandwidth-delay product is a network performance indicator that represents the maximum number of bits on a communication link. In this embodiment, the network parameters may include various parameters for indicating the network performance, such as the rate, bandwidth, throughput, delay-bandwidth product, network delay, etc. of the network transmission. The network parameters involved in this embodiment include the maximum transmission rate that the network can carry, the network latency of the communication between the client and the server, and the bandwidth-latency product of the network.
Optionally, when the network parameter includes a bandwidth delay product, the step S103 "obtaining the network parameter according to the maximum transmission rate and the network delay corresponding to the mutation point" specifically includes: and determining a bandwidth delay product according to the network delay and the maximum transmission rate.
The present embodiment relates to a method for determining a bandwidth-delay product by a measurement device, and optionally, the measurement device may perform a multiplication operation on the acquired network delay and the maximum transmission rate, and an obtained product is the bandwidth-delay product. Optionally, the measurement device may also perform weighting processing on the obtained network delay and the maximum transmission rate, and then perform multiplication operation on the processed network delay and the maximum transmission rate, so that an obtained product is a bandwidth delay product.
In one embodiment, fig. 3 is a flowchart of a method for measuring a network parameter according to one embodiment. The embodiment relates to a specific process that a measurement device performs message interaction with a client and a server in a measurement process of the measurement device, and as shown in fig. 3, the process includes:
s201, receiving a TCP response message sent by a client.
The TCP response message is a response message replied to the server after the client receives the message sent by the server, so that the server can learn the condition of the client receiving the message according to the response message.
In this embodiment, in the process of measuring the network parameter, the measurement device also needs to receive a TCP response message sent by the client, so as to perform corresponding message processing or time delay processing on the TCP response message, so as to forward the processed TCP response message to the server, so that the measurement device can monitor the data transmission condition on the network between the client and the server in real time.
And S202, when the preset delay time is reached, sending a TCP response message to the server side.
The delay time can be customized by a user according to actual application requirements, and is used for indicating the time for the measurement equipment to delay forwarding of the TCP response message.
Based on the foregoing embodiment, it can be understood that the present embodiment describes a process in which the measurement device performs delay processing on a TCP response message received from the client, that is, the measurement device sets a delay time in advance, and then after the measurement device receives the TCP response message sent by the client and needs to wait for the delay time, the measurement device sends the TCP response message to the server, so as to ensure that the server can normally receive the TCP response message sent by the client. The delay time may be a variable time, the initial value may be set to 0, or may be set to another value, and the delay time may be periodically changed in an increasing manner, which is not limited in this embodiment.
As shown in fig. 3A, in the data transmission process, the server sends a downstream TCP message (D1, D2, D3, D4, D5) to the client, and the client sends an upstream TCP response message (p1, p2, p3, p4, p5) to the server after receiving the downstream TCP message. With the solution of this embodiment, when the measurement device measures the transmission performance of the transmission network between the client and the server, the measurement device may receive the TCP response message (p1, p2, p3, p4, p5) sent by the client, and send the TCP response message (p1, p2, p3, p4, p5) to the server after performing the delay processing on the TCP response message, that is, when the preset delay time arrives.
In the above embodiment, the measurement device receives the TCP response message sent by the client during the process of measuring the network parameter, and sends the TCP response message to the server when the preset delay time is reached. In the transmission process, since the delay time is a variable quantity, the delay time can be adjusted by a user according to actual application requirements, and when the measurement device monitors a variation trend of the transmission rate of the network each time, the delay time needs to be adjusted to change the transmission rate of the network, so that the measurement device can measure the maximum transmission rate of the network from the variable transmission rate. The measurement method only needs to adjust the delay time to change the actual time delay characteristic of the network, so as to change the actual transmission rate of the network, and then further can measure the network parameters which can be borne by the network by monitoring the change trend of the transmission rate of the network, so that the measured network parameters are closer to the actual performance parameters of the network.
In one embodiment, fig. 4 provides a flow chart of one implementation of the embodiment S101 of fig. 2. The embodiment relates to a specific process in which the measurement device monitors a variation trend of the transmission rate of the network, and as shown in fig. 4, the step S101 "monitoring a variation trend of the transmission rate of the network" includes:
s301, acquiring the transmission rate of the network according to a preset time period.
In this embodiment, when the measurement device monitors a change trend of the transmission rate of the network, the measurement device may set a fixed time, for example, 5s, 4s, 3s, and the like, and then monitor the transmission rate of the network with the time as a period, and record the transmission rate corresponding to each time point.
S302, monitoring whether a rate-reduced mutation point appears in the change trend according to the transmission rate.
In this embodiment, when the measurement device obtains the transmission rate at the current time point, whether a sudden change point with a reduced rate occurs in the change trend may be further monitored by analyzing the variation between the transmission rate and the transmission rate recorded at the adjacent time point. And when the variation is within a preset threshold range, determining that a rate-reduced mutation point appears on the variation trend, and otherwise, determining that no rate-reduced mutation point appears on the variation trend. It should be noted that, the threshold range may be set by the measurement device in advance according to the actual application requirement, and this embodiment is not limited thereto.
In one embodiment, FIG. 5 provides a flow chart of one implementation of S302 of the embodiment of FIG. 4. This embodiment relates to a specific procedure where the measurement device determines the discontinuity point based on the monitored transmission rate. As shown in fig. 5, in the step S302 "monitoring whether a rate-decreasing abrupt point occurs according to the transmission rate includes:
s401, judging whether the transmission rate is reduced, if so, executing a step S402; if the transmission rate is not decreased, step S403 is performed.
In this embodiment, when monitoring a change trend of the transmission rate of the network each time, the measurement device may record the transmission rate monitored each time in the cache. When the measurement device monitors whether a rate-decreasing discontinuity point occurs according to the transmission rate monitoring change trend, specifically, the transmission rate monitored this time may be compared with the transmission rate recorded in the previous monitoring, and whether the transmission rate monitored this time decreases is analyzed, if the monitored transmission rate decreases, the measurement device may perform the step of S402, and if the monitored transmission rate does not decrease, the measurement device may perform the step of S403.
S402, determining the mutation point with the reduced rate of change trend.
In this case, the measurement device determines that a sudden point at which the rate of change in the transmission rate of the network decreases occurs.
And S403, accumulating the delay time to obtain new delay time, and sending a TCP response message to the server when the new delay time is reached.
In this application, when receiving a TCP response message sent by a client, the measurement device first performs numerical accumulation on the delay time to change the delay time, and then forwards the TCP response message to a server after a new delay time. At this time, the measurement device may return to the step of performing S101 to re-monitor the change trend of the transmission rate of the network until the abrupt point of the decrease of the rate of the change trend is monitored, thereby completing the measurement of the network parameter. It should be noted that, when the measurement device performs the numerical value accumulation operation on the delay time, the numerical value accumulated each time may be determined according to the actual application requirement, and may be 0.5ms, 1ms, 2ms, and the like.
After the measuring device obtains the network parameters according to the method for measuring network parameters described in any of the embodiments above, in order to match the actual performance of the network with the network performance agreed by the service quality parameters preset in the network as much as possible, thereby not causing waste of resources, and avoiding phenomena such as network congestion, delay, and unstable network rate caused by mismatch, the measuring device may further configure the network according to the guidance of the network parameters, and therefore, in one embodiment, the present application further provides a method for configuring a network according to the network parameters and the service quality parameters matched with the network parameters, which specifically includes: and configuring the cache of the network according to the bandwidth-delay product, and configuring the network according to the service quality parameter matched with the network parameter. In this embodiment, when the measurement device obtains the network parameter by using the method for measuring the network parameter and the network parameter includes a bandwidth delay product, the measurement device may directly set a space size of a cache of each switching device in the network according to a value of the bandwidth delay product, and may specifically configure the cache by using the value of the bandwidth delay product as a design index of the cache size. Optionally, the measurement device may further select a quality of service parameter matching the bandwidth-delay product value by analyzing the bandwidth-delay product value to configure hardware and software of the network.
The method for measuring network parameters provided by the embodiment realizes the process of selecting the matched service quality parameters according to the measured network parameters and configuring the network according to the matched service quality parameters, so that the network performance of the network in practical application can be kept consistent with the network performance agreed by the service quality parameters by the method for configuring the network, the network data packet loss, congestion and delay are avoided, and the normal rate transmission of the network is greatly ensured.
With reference to all the above embodiments, the present application further provides a method for measuring a network parameter, as shown in fig. 6, the method specifically includes:
s501, a delay time (initial value is 0) is initialized.
And S502, receiving a TCP response message sent by the client.
And S503, when the delay time is up, sending the TCP response message to the server.
S504, monitoring the transmission rate of the network.
S505, judging whether the transmission rate of the network is reduced, if so, executing S506; if not, S509 is executed.
S506, stopping monitoring, determining the transmission rate at the moment as the maximum transmission rate of the network, and acquiring the network time delay from the client to the server at the moment.
And S507, calculating the maximum bandwidth delay product according to the maximum transmission rate and the network delay.
And S508, selecting matched service quality parameters according to the maximum transmission rate, the network delay and the maximum bandwidth-delay product, and configuring the network.
And S509, accumulating the delay time by a value 1 to obtain new delay time.
S510, after waiting for a preset time (e.g., 5S), the process returns to S502.
In the method for measuring network parameters provided in the above embodiment, the measurement device changes the transmission delay of the network by adjusting the delay time, so that networks with different delay characteristics can be simulated, the maximum bandwidth delay product that can be carried by each network can be measured, and then the corresponding quality of service parameter can be selected according to each maximum bandwidth delay product, and specific network deployment and configuration are guided according to each quality of service parameter, so that the actual performance of the configured network is basically consistent with the network performance constrained by the quality of service parameter, thereby avoiding network data packet loss, congestion, and delay, and greatly ensuring normal rate transmission of the network. In addition, by the method, resource waste caused by the fact that the number of actually required caches is small but the number of the marked caches is too large can be avoided, and the utilization rate of resources is greatly improved.
It should be understood that although the various steps in the flow charts of fig. 2-6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
