It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings. Furthermore, embodiments of the invention and features of the embodiments may be combined with each other without conflict.
Example 1
Fig. 1A is a flowchart of a network quality evaluation method according to an embodiment of the present invention, where the embodiment is applicable to any network quality evaluation case performed by a network cluster formed by various basic network devices when a certification network is changed. The method for evaluating network quality provided in this embodiment may be implemented by the device for evaluating network quality provided in this embodiment of the present invention, where the device may be implemented by software and/or hardware, and integrated in a server that performs the method, where the server may be a server that has an analysis function for the transmission traffic of each basic network device in a network cluster.
Specifically, referring to fig. 1A, the method may include the steps of:
s110, simulating a corresponding network change path according to the change configuration information of the current network.
Specifically, a corresponding network cluster can be constructed through data transmission between a large number of basic network devices, that is, a plurality of network nodes exist in the current network in this embodiment, and corresponding data transmission can be executed between each network node.
In this embodiment, in order to avoid the problem that the network quality is worse after the current network performs unreasonable change configuration, the influence of the current network change on the network quality is analyzed in advance before the current network performs the actual change operation. Therefore, when it is determined that the current network has a change requirement, change configuration information of the current network is obtained first, where the change configuration information can represent each configuration parameter of each network node in the current network after the change, and further by analyzing the change configuration requirement of each network node in the change configuration information, each network node that exists after the change and a transmission path when each network node performs data transmission after the change can be correspondingly simulated, so as to simulate a network change path after the change of the current network.
It should be noted that, in this embodiment, the network node in the current network may be each basic network device that forms the current network, and a physical interface and a logical interface on each basic network device for performing data transmission, and the network change path after the current network change may be represented by the simulated routing table, forwarding table, connection state table, and media access control (Media Access Control, MAC) address table, so that each transmission path that can be used for transmitting data after the current network change can be accurately represented. When analyzing the MAC address table after the current network change, reference needs to be made to the MAC address table before the current network change and the change configuration information during the current change, so that the MAC address table after the current network change can be accurately obtained, and the binding of the physical interface and the logical interface on each network node simulated by the current network change is realized.
S120, the historical flow data of the current network is controlled to be forwarded on the network change path, and the corresponding network change quality is evaluated based on the quality factor difference before and after the current network change.
Optionally, before the current network executes the real change operation, a corresponding network change path can be simulated according to the change configuration information of the current network, the data transmission path after the current network is changed is represented by the network change path, at this time, each historical flow data of the data transmission performed by the current network before the change can be collected, the historical flow data can be collected in a data packet mode, and includes various flow data transmitted before the current network change, information such as a source MAC address, a target MAC address, a source IP address, a target IP address and the like of the data packet, at this time, by analyzing the historical flow data correspondingly transmitted on each network node before the current network change, the network quality indicating the network transmission capability under each quality factor before the current network change can be judged.
Then, in order to analyze the network quality after the current network change, the embodiment may further control each piece of flow data in the real historical flow data before the current network change to perform simulated forwarding in the simulated network change path, as shown in fig. 1B, by analyzing the simulated data transmission condition in the network change path, the network quality indicating the network transmission capability under each quality factor after the current network change is analyzed. At this time, by comparing the network quality difference under each quality factor before and after the current network change, the quality factor difference before and after the current network change can be judged, so that the network change quality after the current network change is evaluated relative to the network change quality before the change, thereby realizing the advanced evaluation of the network change quality, and the quality evaluation is performed without the current network executing the real change operation, avoiding the unreasonable change configuration of the current network and preventing the problem of worse network quality caused by unreasonable network change.
It should be noted that, the quality factor in this embodiment may be various reference factors in the current network, which may affect the network quality change, for example, the number of route changes and the number of port state changes before and after the network change, so as to automatically analyze the network quality after the current network change from multiple dimensions, and improve the accuracy of evaluating the network quality.
According to the technical scheme provided by the embodiment, before the current network is changed, a network change path after the current network is changed is firstly simulated according to the change configuration information of the current network, then historical flow data before the current network is controlled to be forwarded on the simulated network change path, so that the data transmission capacity after the current network is analyzed, and the corresponding network change quality is evaluated based on the quality factor difference before and after the current network is changed, so that the advanced evaluation of the network change quality is realized, the quality evaluation is carried out without the current network executing real change operation, the unreasonable change configuration of the current network is avoided, and the problem of poorer network quality caused by unreasonable change of the network is prevented; meanwhile, before the current network is truly changed, the simulated network change path can be utilized to carry out automatic network change quality assessment, subjective experience of engineering personnel on network change is not needed, and assessment accuracy of network change quality is improved.
Example two
Fig. 2A is a flowchart of a network quality evaluation method according to a second embodiment of the present invention, and fig. 2B is a schematic diagram of a network quality evaluation process according to a second embodiment of the present invention. This embodiment is optimized based on the above embodiment. Specifically, as shown in fig. 2A, the present embodiment explains in detail the simulation process of the current network change and the evaluation process of the network change quality.
Optionally, as shown in fig. 2A, the present embodiment may include the following steps:
s210, responding to the change instruction of the current network, and analyzing change configuration information in the change instruction.
Optionally, when a change requirement exists in the current network, an engineer may input corresponding change configuration information and trigger to execute a corresponding change operation, thereby generating a change instruction of the current network. At this time, the traffic analysis server for executing the evaluation method of network quality in this embodiment may receive the change instruction of the current network, and respond to the change instruction, and execute the analysis operation of the change instruction to analyze the specific change scheme of the current network, that is, the change configuration information in this embodiment, so as to analyze the changed network structure by using the change configuration information.
It should be noted that, the change configuration information in this embodiment may be interpreted by using a change configuration script, and then the network structure after the current network change may be simulated by running the change configuration script in a simulation manner.
S220, configuring corresponding simulation execution points according to the change configuration information so as to simulate corresponding network change paths by using the simulation execution points.
Specifically, by analyzing the change configuration information of the current network, each network node existing after the current network is changed and the actual configuration parameter of each network node can be judged. Therefore, as shown in fig. 2B, in this embodiment, the simulation execution points existing in the open platform provided by the graphics simulator GNS or each hardware manufacturer may be used to replace each network node existing after the current network is changed, and each simulation execution point is configured accordingly by adopting the change configuration parameters of each network node, so that the changed network structure can be simulated through the configuration condition of each simulation execution point, that is, each configuration parameter used to represent the data transmission requirement on each simulation execution point, to simulate the network change path after the current network is changed, without performing a real change operation on the current network before the network change quality evaluation, so as to avoid the negative influence of the unreasonable change scheme on the current network.
For example, in this embodiment, the corresponding simulation execution point may be configured by executing the change configuration script for representing the change configuration information of the current network through simulation. Meanwhile, in order to ensure the consistency with the network interface before the change, in this embodiment, according to the change configuration information and the data transmission interface information contained in the historical traffic data before the change of the current network, the interface identifier (such as the index serial number) of each simulation execution point is modified to be consistent with the network interface before the change, so as to ensure the effectiveness when the historical traffic data before the change is forwarded by using the simulated network change path.
S230, the historical flow data of the current network is controlled to be forwarded on the network change path, and the change flow situation of the network change path is recorded.
In this embodiment, after a network change path after a current network change is simulated, by controlling historical traffic data of the current network to be forwarded on each path strength in the network change path, a traffic change state when data is transmitted on each network node in the network change path can be analyzed, so as to obtain a changed traffic situation of the network change path, where the changed traffic situation is used to indicate a traffic change situation of each network node in the network change path, where the traffic change situation is used to indicate a data transmission capability, for example, whether traffic congestion, bandwidth remaining, or the like occurs, and by using the changed traffic state potential, network quality under each quality factor after the current network change can be analyzed.
It should be noted that, in this embodiment, the traffic situation may be represented by a traffic time curve on each node in the network rerouting path. At this time, the data plane development suite (Data Plane Development Kit, DPDK) may be used to analyze the actual transmission situation of the historical traffic data on each node in the network change path, and further draw the traffic time curve on each node, so as to represent the change traffic situation of the network change path.
In addition, the historical flow data in the embodiment can be flow data actually transmitted in the current network in the latest preset time period before the current network receives the change instruction, in the same preset time period in the previous day and the previous week, and the quality factor difference before and after the current network is changed can be correspondingly analyzed according to the specific flow change conditions of the original flow situation and the changed flow situation in the time period to which the corresponding historical flow data belongs, so that the evaluation accuracy of the network change quality is ensured.
S240, analyzing the change difference of the current network under each quality factor based on the original traffic situation and the changed traffic situation before the current network is changed.
Optionally, before the current network is changed, the embodiment continuously collects the historical traffic data actually transmitted in the current network, then analyzes the actual transmission condition of the historical traffic data on each node before the current network is changed by adopting a data plane development kit DPDK, and further draws a traffic time curve on each node before the current network is changed, so as to represent the original traffic situation before the current network is changed. That is, historical traffic data captured by the DPDK of the data plane development kit is summed up and counted to each network node (such as each network device and each network interface) before the current network change, and then a traffic time curve on each network node before the current network change is drawn according to the time node.
And by comparing the original flow situation before the current network is changed with the changed flow situation after the current network is changed, the real overall network quality situation before and after the current network is changed can be analyzed, and further the flow change situation which can influence the network quality under each quality factor before and after the current network is changed is judged, so that the network quality change situation before and after the current network is changed under each quality factor is obtained, the network quality change situation before and after the current network is changed under each quality factor is compared, and the change difference of the current network under each quality factor is obtained, so that the corresponding network change quality is evaluated according to the change difference of the current network under each quality factor.
In addition, if there is transmission congestion after the current network is changed, it is indicated that the change mode indicated by the change configuration information is not suitable for the current network, and the problem of network transmission congestion after the current network is changed can occur, so that in this embodiment, after the historical traffic data of the current network is controlled to be forwarded on the network change path, the change traffic situation of the network change path is recorded, and then whether there is transmission congestion after the current network is changed is judged according to the specific traffic change situation after the current network is changed, which is indicated by the change traffic situation, if yes, the final network change quality is directly determined to be abnormal, and the change of the current network by using the change configuration information is refused; otherwise, continuing to analyze the change difference of the current network under each quality factor to evaluate the corresponding network change quality.
For example, after each analog execution point is configured correspondingly according to the configuration changing information, the historical flow data can be forwarded, and then the flow time curve of each interface on each analog execution point, that is, the changed flow situation of the network change path, is counted, so that the peak flow point on each network node is checked and compared with the corresponding physical interface bandwidth, and at this time, if the peak flow is greater than 90% of the interface bandwidth, the transmission congestion is directly determined.
S250, based on the change difference of the current network under each quality factor, the corresponding network change quality is evaluated.
In this embodiment, after the change difference of the current network under each quality factor is analyzed, whether the network quality change caused by the change difference under each quality factor is positive or negative can be determined, so that the quality score is used to indicate the corresponding network change quality by using the weight of each quality factor to perform the quality score on the network change quality after the current network change.
If the simulated historical flow data occupies too high bandwidth during data forwarding of the network change path, deduction is carried out, and corresponding flow difference analysis can be carried out based on various quality factors such as the number of error execution times of the change script, the number of route change and the number of port state change, so that evaluation conditions under various quality factors are synthesized, and a final quality score of network change quality is obtained.
According to the technical scheme provided by the embodiment, before the current network is changed, the corresponding simulation execution point is configured through the change configuration information of the current network to simulate the network change path after the current network is changed, then the historical flow data before the current network is controlled to be forwarded on the simulated network change path, and the data transmission capacity after the current network is analyzed through the original flow situation and the change flow situation, so that the corresponding network change quality is evaluated based on the change difference of the current network under each quality factor, the advanced evaluation of the network change quality is realized, the quality evaluation is carried out without the current network executing real change operation, the unreasonable change configuration of the current network is avoided, and the problem that the network quality is worse after the unreasonable change of the network is prevented; meanwhile, before the current network is truly changed, the simulated network change path can be utilized to carry out automatic network change quality assessment, subjective experience of engineering personnel on network change is not needed, and assessment accuracy of network change quality is improved.

Moreover, a Telemetry technology is also adopted to collect a routing table, a forwarding table, a MAC address table, a connection state table and the like before the current network change so as to obtain an original path before the current network change, so that quality factor differences before and after the current network change can be analyzed later.
S320, simulating a corresponding network change path according to the change configuration information of the current network.
S330, judging whether the network change path is consistent with the original path before the current network change; if yes, executing S340; if not, S350 is performed.
Optionally, in this embodiment, whether the network change path after the current network change is consistent with the original path before the current network change may be analyzed by determining whether entries in the routing table, the forwarding table, the MAC address table, the connection state table, and the like are changed before and after the current network change. If the table entries are unchanged, the paths before and after the current network change are consistent, and at the moment, the network quality requirement before the current network change can be met when the data transmission is carried out according to the network change paths, so that the final network change quality can be directly determined to be normal, and the condition that the network quality before and after the current network change is unchanged is indicated. However, if the network change path after the current network change is inconsistent with the original path before the current network change, the quality factor difference before and after the current network change needs to be analyzed to evaluate the corresponding network change quality.
And S340, determining that the final network change quality is normal.

S360, forwarding the change configuration information of the current network to an artificial evaluation platform, and prompting a corresponding change optimization point to obtain a final network evaluation result.
In this embodiment, no matter whether the assessed network change quality is normal, the change configuration information of the current network is forwarded to the manual assessment platform, and corresponding change optimization points are prompted to the manual assessment platform according to the analyzed quality factor difference before and after the current network change, for example, after a change scheme with a quality score lower than a baseline value is determined and refused, the optimization points existing in the change scheme are analyzed according to the actual difference before and after the current network change so as to optimize the change configuration information, if the number of change script errors is greater than n, standard current network configuration is provided; and for the change scheme with the quality score exceeding the baseline value, the corresponding deduction point is prompted to integrally optimize the change configuration information of the current network, so that a final network evaluation result is obtained, and the network change quality is integrally improved after the current network is changed by adopting the change configuration information.
According to the technical scheme provided by the embodiment, the manual evaluation platform is used for carrying out secondary evaluation on the change configuration information of the current network, and optimizing the change configuration information according to the prompted change optimizing point, so that a final network evaluation result is obtained, the evaluation accuracy of the network change quality is ensured, and the overall quality of the network after the network change is improved.
