Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1A is a flowchart of a method for evaluating network quality according to an embodiment of the present invention, which is applicable to a case where network quality evaluation is performed on any network cluster composed of various types of basic network devices when a network change is certified. The method for evaluating network quality provided in this embodiment may be performed by the apparatus for evaluating network quality provided in the embodiment of the present invention, where the apparatus may be implemented in a software and/or hardware manner, and is integrated in a server for performing the method, and the server may be a server side that analyzes transmission traffic of each basic network device in a network cluster.
Specifically, referring to fig. 1A, the method may include the steps of:
and 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 among a large number of basic network devices, that is, a plurality of network nodes exist in the current network of this embodiment, and corresponding data transmission can be performed among the network nodes, at this time, in order to ensure high transmission efficiency and comprehensive coverage of the current network, a corresponding network change requirement inevitably exists in the current network, for example, when a certain network node fails, the current network needs to be upgraded, or an equipment component of the certain network node needs to be replaced and updated, or a new network node needs to be added to the current network, and the like.
In this embodiment, in order to avoid the current network from performing an unreasonable change configuration, thereby preventing the problem of worse network quality caused by an unreasonable change of the network, the influence of the current network change on the network quality is analyzed in advance before the current network performs a real 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, and the change configuration information can represent various configuration parameters of each network node in the current network after the network node participates in the change, so that by analyzing the configuration requirement of each network node change in the change configuration information, each network node existing after the change and a transmission path of each network node after the change during data transmission can be correspondingly simulated, and thus, a network change path after the current network change is simulated.
It should be noted that, in this embodiment, the network node in the current network may be each basic network device constituting the current network, and a physical interface and a logical interface for performing data transmission on each basic network device, and the network change path after the current network change may be represented by a simulated routing table, a forwarding table, a connection state table, a Media Access Control (MAC) address table, and the like, and can accurately represent each transmission path that can be used for transmitting data after the current network change. When analyzing the MAC address table after the current network change, the MAC address table before the current network change and the change configuration information during the current network change need to be referred to, 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.
And S120, controlling the historical flow data of the current network to be forwarded on the network change path, and evaluating the corresponding network change quality based on the quality factor difference before and after the current network change.
Optionally, before the current network performs the real change operation, the 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 data transmission of the current network before the change can be collected, the historical flow data can be collected by adopting a data packet mode and comprises various flow data transmitted before the current network is changed, information such as a data transmission path and the like, for example, the source MAC address, the destination MAC address, the source IP address, the destination IP address, etc. of the data packet, at this time, by analyzing the historical traffic 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 determined.
Then, in order to analyze the network quality after the current network change, this embodiment may further control each piece of traffic data in the real historical traffic 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 the moment, the quality factor difference before and after the current network change can be judged by comparing the network quality difference under each quality factor before and after the current network change, so that the quality of the network change after the current network change is evaluated relative to the quality of the network change before the change, thereby realizing the advanced evaluation of the network change quality without performing the quality evaluation after the current network performs the real change operation, avoiding the unreasonable change configuration of the current network, and preventing the problem of poorer network quality caused by the unreasonable change of the network.
It should be noted that the quality factor in this embodiment may be various reference factors that can affect the network quality change in the current network, such as the number of route changes before and after the network change, the number of port state changes, and the like, so that the network change quality after the current network change is automatically analyzed from multiple dimensions, and the accuracy of evaluating the network change quality is improved.
According to the technical scheme provided by the embodiment, before a current network is changed, a network change path after the current network is changed is simulated according to change configuration information of the current network, historical flow data before the current network is changed is controlled to be forwarded on the simulated network change path, and data transmission capacity after the current network is changed is analyzed, so that the corresponding network change quality is evaluated based on quality factor difference before and after the current network is changed, and therefore, the network change quality is evaluated in advance, the quality evaluation is not required to be carried out after the current network carries out real change operation, unreasonable change configuration of the current network is avoided, and the problem that the network quality is worse after unreasonable change of the network is avoided; meanwhile, before the current network is actually changed, the simulated network change path can be used for carrying out automatic network change quality evaluation, the subjective experience of engineering personnel on network change is not needed, and the evaluation accuracy of the 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 the second embodiment of the present invention. The embodiment is optimized on the basis of the embodiment. Specifically, as shown in fig. 2A, the present embodiment explains the simulation process of the current network change and the evaluation process of the network change quality in detail.
Optionally, as shown in fig. 2A, the present embodiment may include the following steps:
s210, in response to the change instruction of the current network, analyzing the change configuration information in the change instruction.
Optionally, when the current network has a change requirement, the engineer may input corresponding change configuration information and trigger execution of a corresponding change operation, so as to generate a change instruction of the current network. At this time, the traffic analysis server for executing the method for evaluating network quality in this embodiment may receive a change instruction of the current network, and in response to the change instruction, execute an analysis operation of the change instruction to analyze a specific change scheme that is to change the current network at this time, that is, the change configuration information in this embodiment, so as to analyze the network structure after being changed by using the change configuration information in the subsequent step.
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 simulating and running the change configuration script.
And S220, configuring the corresponding simulation execution point according to the change configuration information so as to simulate the corresponding network change path by using the simulation execution point.
Specifically, by analyzing the change configuration information of the current network, the network nodes existing after the current network is changed and the actual configuration parameters of each network node can be determined. Therefore, as shown in fig. 2B, in this embodiment, the simulation execution points existing in the open platform provided by the graphic simulator GNS or each hardware manufacturer may be used to replace each network node existing after the current network is changed, and the change configuration parameters of each network node are used to configure each simulation execution point correspondingly, so that the changed network structure can be simulated through the configuration condition of each simulation execution point, that is, the network change path after the current network is changed is simulated through each configuration parameter used for representing the data transmission requirement on each simulation execution point, and it is not necessary to perform a real change operation on the current network before the network change quality evaluation, so as to avoid a negative impact on the current network caused by an unreasonable change scheme.
For example, in this embodiment, the corresponding simulation execution point may be configured by simulating and running a change configuration script that represents change configuration information of the current network. Meanwhile, in order to ensure the consistency with the network interface before the change, the present embodiment modifies the interface identifier (such as an index serial number) of each simulation execution point to be consistent with the interface identifier before the change according to the change configuration information and the data transmission interface information included in the historical traffic data before the current network change, so as to ensure the validity when the simulated network change path is used for forwarding the historical traffic data before the change.
And S230, controlling the historical traffic data of the current network to be forwarded on the network change path, and recording the change traffic situation of the network change path.
In this embodiment, after a network change path after a current network change is simulated, a traffic change state during data transmission at each network node in the network change path can be analyzed by controlling historical traffic data of the current network to be forwarded on each path in the network change path, so as to obtain a change traffic situation of the network change path, where the change traffic situation is used to indicate a traffic change situation of each network node in the network change path, which is used to indicate data transmission capability, such as whether traffic congestion occurs or bandwidth surplus occurs, and network quality under each quality factor after the current network change can be analyzed through the change traffic situation.
It should be noted that the changed traffic situation in this embodiment may be represented by a traffic time curve on each node in the network changed path. At this time, a Data Plane Development Kit (DPDK) may be used to analyze the actual transmission condition of the historical traffic Data on each node in the network change path, and further draw a traffic time curve on each node, so as to represent the change traffic situation of the network change path.
In addition, the historical traffic data in this embodiment may be traffic data actually transmitted in the current network in the same preset time period within the last preset time period, the previous day, and the previous week before the current network receives the change instruction, and the quality factor difference before and after the current network change may be analyzed subsequently according to the specific traffic change condition of the original traffic situation and the change traffic situation in the time period to which the corresponding historical traffic data belongs, so as to ensure the accuracy of the evaluation of the network change quality.
S240, analyzing the change difference of the current network under each quality factor based on the original flow situation and the changed flow situation before the current network is changed.
Optionally, before the current network is changed, the embodiment continuously collects historical traffic data actually transmitted in the current network, and then analyzes an actual transmission condition of the historical traffic data on each node before the current network is changed by using a data plane development kit DPDK, so as to draw a traffic time curve on each node before the current network is changed, thereby representing an original traffic situation before the current network is changed. That is, the historical traffic data captured by the data plane development kit DPDK is summarized and counted to each network node (e.g., 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 comparing the original flow situation before the current network change with the changed flow situation after the current network change to analyze the real overall network quality situation before and after the current network change, and further judging the flow change situation before and after the current network change which can affect the network quality under each quality factor so as to obtain the network quality change situation before and after the current network change under each quality factor, and comparing the network quality change situation before and after the current network change under each quality factor to obtain the change difference of the current network under each quality factor so as to evaluate the corresponding network change quality 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 described 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 this embodiment controls the historical traffic data of the current network to be forwarded on the network change path, records the change traffic situation of the network change path, and then determines whether there is transmission congestion after the current network is changed according to the specific traffic change situation after the current network is changed, which is indicated by the change traffic situation, and if so, directly determines that the final network change quality is abnormal, thereby rejecting to change the current network by using the change configuration information; otherwise, the change difference of the current network under each quality factor is continuously analyzed to evaluate the corresponding network change quality.
For example, in this embodiment, after performing corresponding configuration on each simulation execution point according to the change configuration information, historical traffic data may be forwarded, and then a traffic time curve of each interface on each simulation execution point, that is, a change traffic situation of a network change path, is counted, so as to check a peak traffic point on each network node and compare the peak traffic point with a corresponding physical interface bandwidth, and at this time, if the peak traffic is greater than 90% of the interface bandwidth, it is directly determined that transmission congestion occurs.
And S250, evaluating the corresponding network change quality based on the change difference of the current network under each quality factor.
In this embodiment, after analyzing the change difference of the current network under each quality factor, it may be determined whether the network quality change caused by the change difference under each quality factor is a positive influence or a negative influence, so as to perform quality scoring on the network change quality after the current network change by using the weight of each quality factor, and express the corresponding network change quality by using the quality scoring.
Illustratively, if the simulated historical traffic data occupies too high bandwidth during data forwarding of the network change path, the deduction is performed, and corresponding traffic difference analysis can be performed on each quality factor, such as the number of execution errors of the change script, the number of route changes, the number of port state changes, and the like, so that the evaluation conditions under each quality factor are integrated to obtain the final quality score of the network change quality.
In the technical scheme provided by the embodiment, before a current network is changed, a corresponding simulation execution point is configured through change configuration information of the current network to simulate a network change path after the current network is changed, then historical flow data before the current network is changed is controlled to be forwarded on the simulated network change path, and data transmission capacity after the current network is changed is analyzed through an original flow situation and a change flow situation, so that corresponding network change quality is evaluated based on change difference of the current network under each quality factor, thereby realizing advanced evaluation of the network change quality, avoiding quality evaluation after the current network performs real change operation, avoiding unreasonable change configuration of the current network, and preventing the problem of poorer network quality after unreasonable change of the network; meanwhile, before the current network is actually changed, the simulated network change path can be used for carrying out automatic network change quality evaluation, the subjective experience of engineering personnel on network change is not needed, and the evaluation accuracy of the network change quality is improved.

and S310, acquiring historical flow data of the current network and the original path of the current network before change by using a telemetry technology.
Optionally, in order to implement network quality comparison before and after the current network change, in this embodiment, before the current network change, a Telemetry telemetrology technology is adopted, and information such as corresponding interface traffic statistics, CPU or memory data is periodically and actively uploaded to a traffic analysis server by each network node through a Push Mode (Push Mode), so as to obtain historical traffic data of the current network, and analyze information such as a source MAC address, a target MAC address, a source IP address, and a target IP address of the historical traffic data. In addition, a routing table, a forwarding table, an MAC address table, a connection state table, and the like before the current network change are collected by using a Telemetry telemetering technology to obtain an original path before the current network change, so as to analyze the quality factor difference before and after the current network change.
And 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, go to S340; if not, go to S350.
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 before and after the current network change. If the table entries are not changed, it is indicated that the paths before and after the current network change are consistent, and at this time, when data transmission is performed according to the network change path, the network quality requirement before the current network change can be met, so that the final network change quality can be directly determined to be normal, thereby indicating that the network quality before and after the current network change does not change. 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 the final network change quality to be normal.

In this embodiment, regardless of whether the evaluated network change quality is normal, the change configuration information of the current network is forwarded to the manual evaluation platform, and meanwhile, according to the analyzed quality factor difference before and after the current network change, a corresponding change optimization point is prompted to the manual evaluation platform, for example, for a change scheme with a quality score lower than a baseline value, after the change scheme is determined to be rejected, the optimization point existing in the change scheme is analyzed according to the actual difference before and after the current network change, so as to optimize the change configuration information, and if the change script error frequency is greater than n times, a standard current network configuration is provided; and for the change scheme with the quality score exceeding the baseline value, prompting a corresponding point of deduction to carry out overall optimization on the change configuration information of the current network so as to obtain a final network evaluation result, so that the network change quality is integrally improved after the change configuration information is adopted to change the current network.
According to the technical scheme provided by the embodiment, the change configuration information of the current network is secondarily evaluated through the manual evaluation platform, and the change configuration information is optimized according to the prompted change optimization 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 change is improved.
