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.
In an embodiment, as shown in fig. 1, a network performance testing method based on simulation software is provided, and this embodiment is illustrated by applying the method to a terminal, it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method may include the steps of:
As an example, the grid dispatching data network may be a network used by a grid enterprise, and in the grid dispatching data network, a plurality of communication nodes which communicate using an IPv6 protocol may be included, and a backbone network using an IPv4 protocol, where the backbone network may refer to a high-speed network used to connect a plurality of areas or regions. Each backbone network can have at least one connection point for interconnecting with other backbone networks, and the function range of the backbone network can reach dozens to thousands of kilometers.
The network topology may refer to the distribution and connection of computer devices in a network formed by computer devices, and as shown in fig. 2, is an example of a network topology. In particular implementations, the computer devices in the network topology may include any one or more of the following: terminal, server, router.
In practical application, a network topology structure corresponding to the power grid dispatching data network can be obtained, and since the network topology structure can describe the distribution situation and the connection mode of computer equipment in the power grid dispatching data network, the network topology structure can include a plurality of communication nodes which use the IPv6 protocol for communication in the power grid dispatching data network and a backbone network which uses the IPv4 protocol.
102, acquiring configuration parameters corresponding to the network topology structure and tunnel parameters of a network tunnel configured for the backbone network as network configuration parameters; the network tunnel is a network tunnel corresponding to an IPv6 protocol and an IPv4 protocol.
As an example, the configuration parameters may include parameters describing connection and distribution of each computer device in the network topology, such as address information, connection mode, and the like of each computer device.
A network tunnel may refer to a network protocol used to transmit data of another network protocol, for example, data of IPv6 transmitted through an IPv4 network, and a tunnel parameter may be a corresponding parameter of the network tunnel.
The network configuration parameters may be parameters that are used to describe characteristics of the network structure or devices, links, etc. in the network, and are used in building the network model.
After the network topology is obtained, the configuration parameters corresponding to the network topology can be obtained. Meanwhile, the backbone network adopts the IPv4, which is different from the IPv6 protocol adopted by the plurality of communication nodes, so that a network tunnel corresponding to the IPv6 protocol and the IPv4 protocol can be configured for the backbone network, and through the network tunnel, the IPv4 network can be used to transmit the data of the IPv 6.
In a specific implementation, a tunnel parameter corresponding to a network tunnel may be obtained, and the configuration parameter and the tunnel parameter may be used as the network configuration parameter. For example, a user may perform device operation on configuration parameters and tunnel parameters corresponding to a network structure to obtain network configuration parameters.
As an example, the simulation software may be software, such as Opnet software, that obtains network performance data required for network design or optimization by modeling network devices, links, and protocols, and simulating the transmission of network traffic.
In practical application, after the network tunnel parameters are obtained, the network configuration parameters can be input into simulation software, so as to construct a network model through the simulation software.
And 104, creating a simulation service flow, inputting the simulation service flow into the network model, and obtaining a corresponding first network service quality parameter when the plurality of communication nodes transmit the simulation service flow through the network tunnel.

After the network model is constructed, a simulation service flow can be created and input into the network model, so that a plurality of communication nodes are simulated through the network model to transmit the simulation service flow by using a network tunnel, and a corresponding network service quality parameter, namely a first network service quality parameter, can be obtained in the transmission process.
And 105, determining the network performance of the power grid dispatching data network when the network tunnel is configured according to the first network service quality parameter.
After the first network service quality parameter is obtained, the network performance of the power grid dispatching data network during the configuration of the network tunnel can be determined according to the parameter. Specifically, a preset network performance standard may be obtained, and the first network quality of service parameter is compared with the network performance standard to determine whether the power grid scheduling data network can provide a network meeting the network performance standard when the network tunnel is configured.
In the embodiment, a network topology structure corresponding to a power grid dispatching data network is obtained, configuration parameters corresponding to the network topology structure and tunnel parameters of a network tunnel configured for a backbone network are obtained and used as network configuration parameters, the network configuration parameters are input into simulation software, a network model is built, a simulation service flow is created and input into the network model, a corresponding first network service quality parameter is obtained, and the network performance of the power grid dispatching data network when the network tunnel is configured is determined according to the first network service quality parameter, so that the network simulation of the power grid dispatching data network when the network tunnel is configured is realized, and the network performance can be predicted in advance.
In one embodiment, as shown in fig. 3, the inputting the network configuration parameters into the simulation software to build the network model by the simulation software may include the following steps:
As an example, the emulated device may be a virtual device used in building the network model, and the emulated device may include a router, and a workstation and/or server as the communication node.
In practical applications, since the network is composed of a plurality of computer devices and is determined by the connection relationship and/or distribution condition among the plurality of computer devices, when the network model is constructed, a plurality of simulation devices corresponding to the power grid dispatching data network may be obtained, where the plurality of simulation devices corresponding to the power grid dispatching data network may refer to virtual devices corresponding to real devices used in the power grid dispatching data network, for example, the same device types and/or the same number of devices.
After the simulation equipment is acquired, the simulation equipment and the network configuration parameters can be input into the simulation software, and after the simulation software acquires the simulation equipment and the network configuration parameters, data connection among a plurality of simulation equipment can be established according to the network configuration parameters, so that a network model is constructed. When data connection is carried out, connection can be carried out through a link mode link model of Opnet.
In one example, MPLS (Multi-Protocol Label Switching) VPN (Virtual Private Network) and LSP (layered service provider) Network environments may be rapidly deployed through the Riverbed Modeler MPLS model.
In one example, after the network model is built, each simulation device and/or service in the network model may communicate via a TCP (Transmission Control Protocol).
In this embodiment, the simulation device and the network configuration parameters are input into the simulation software, the simulation software creates data connections among the multiple simulation devices by using the network configuration parameters, and constructs a network model, so that network simulation is realized, and a data basis is provided for a network performance test when a network tunnel is configured.
In one embodiment, the communication node may include a sender node and a receiver node, and the obtaining the configuration parameters corresponding to the network topology may include the following steps:
acquiring interface address information corresponding to an IPv6 node, and taking the interface address information as configuration parameters corresponding to a sending end node and a receiving end node; and acquiring actual service flow information, and determining a configuration parameter corresponding to the network topology structure according to the configuration parameter and the actual service flow information.
As an example, the actual traffic information may be a traffic bandwidth used by the grid scheduling data network in actual operation, such as 2M bandwidth lines, 155M bandwidth lines.
In a specific implementation, interface Address information may be set in advance for the IPv6 node, for example, interface Address information for the IPv6 node host attribute is configured as "No IP Address", and after the communication node configures the interface Address information, the communication node may be identified as the IPv6 node.
Based on this, the preset interface address information for the IPv6 node can be obtained, and the interface address information is used as the configuration parameters corresponding to the sender node and the receiver node, and the sender node and the receiver node are both represented as IPv6 nodes by setting the interface address information. In addition, other IPv6 node information can be configured and used as configuration parameters corresponding to the sending end node or the receiving end node together with interface address information. Furthermore, the actual service flow information corresponding to the power grid dispatching data network can be obtained, and the configuration parameters and the actual service flow information are used as the configuration parameters corresponding to the network topology structure of the power grid dispatching data network.
In this embodiment, by obtaining interface address information and actual service traffic information corresponding to the IPv6 node, configuration parameters corresponding to a network topology structure can be obtained, and a data basis is provided for building a network model.
In one embodiment, the obtaining of the tunnel parameters of the network tunnel configured for the backbone network may include the following steps:
step 301, acquiring a preset router model; the router model includes a first router in communication with the sending end node and a second router in communication with the receiving end node.
In a specific implementation, the power grid scheduling data network may include a plurality of routers, and each station may forward data through the routers for data interaction. Based on this, a preset router model corresponding to the power grid scheduling data network may be obtained, where the router model may include a first router in communication with the sending end node and a second router in communication with the receiving end node, and the first router and the second router may perform data interaction through a backbone network, for example, may be an NE20 router model. In practical application, the router model can be input into simulation software, and a corresponding router connection structure is constructed in the network model through a specified module of the simulation software.
Based on this, when the tunnel parameter corresponding to the network tunnel is obtained, the preset router model can be obtained.
Step 302, acquiring a tunnel interface address and a tunnel interface mode corresponding to the first router and the second router respectively; the tunnel interface address is an address of an IPv6 network tunnel, and the tunnel interface mode is a mode aiming at an IPv6 protocol and an IPv4 protocol.
After obtaining a router model including the first router and the second router, the tunnel interface address and the tunnel interface mode corresponding to the first router may be obtained, and the tunnel interface address and the tunnel interface mode won by the second router may be obtained.
The tunnel interface modes corresponding to the first router and the second router may be both modes for the IPv6 protocol and the IPv4 protocol, that is, an IPv6(6to4) mode. The tunnel interface Address corresponding to the first router and the tunnel interface Address corresponding to the second router may be configured as preset Address information, where the preset Address information is used to characterize that the tunnel provided by the router is an IPv6 tunnel, for example, the preset Address information may be "No IP Address".
Step 303, obtaining the static routing tables corresponding to the first router and the second router, and obtaining the tunnel parameters of the network tunnel configured for the backbone network according to the tunnel interface address, the tunnel interface mode and the static routing tables.
As an example, the static routing table may be configured with a network tunnel identifier and address information corresponding to a target node, where the target node may be a receiving node that is a target object and receives data when the sending end node sends the data, and accordingly, when the receiving end node sends the data, the receiving end node may also be changed into the sending end node.
In specific implementation, a static routing table corresponding to each of the first router and the second router may be obtained, where the static routing table may instruct the router to transmit data to a target node corresponding to address information by using a network tunnel corresponding to a network tunnel identifier when receiving data sent by a sending end node by configuring the network tunnel identifier and address information corresponding to the target node. For example, the address information configured by the IPv6 static routing table of the first router for the destination node is 2002, and the network tunnel identifier configured by the next hop is TunnelA, which may indicate that the IPv6 data is transmitted in the IPv6 tunnel identified by the network tunnel identifier of TunnelA after passing through the 6to4 router, and the destination address of the transmission is the communication node beginning with 2002.
After the static routing table is obtained, the tunnel interface address, the tunnel interface mode, and the static routing table may be determined as tunnel parameters corresponding to the network tunnel configured for the backbone network.
In this embodiment, the tunnel parameters of the network tunnel configured for the backbone network are obtained according to the tunnel interface address, the tunnel interface mode and the static routing table, so that a data basis can be provided for constructing the network model.
In an embodiment, as shown in fig. 4, the determining, according to the first network quality of service parameter, the network performance of the power grid dispatching data network when the network tunnel is configured may include the following steps:
As an example, the second network quality of service parameter may be a parameter reflecting network quality of service, and specifically, may be a network quality parameter of a corresponding network when a network tunnel is not used in the grid scheduling data network and a plurality of communication nodes using an IPv6 protocol perform data transmission through a backbone network. The second network quality of service parameter may comprise any one or more of: packet loss rate, delay information, response time, throughput.
In this embodiment, the second network quality of service parameter may be obtained. Specifically, the second network quality of service parameter may be a network quality of service parameter obtained by constructing a network model through simulation software and inputting a simulation service flow into the network model, where the network model is a network model corresponding to a power grid scheduling data network when a network tunnel is not applicable. Alternatively, the real parameters may be measured by a virtual device, software, or a physical device in a real network.
After the first network service quality parameter and the second network service quality parameter are obtained, the first network service quality parameter and the second network service quality parameter can be compared, and changes of network performance of the power grid dispatching data network when the network tunnel is used are determined, for example, influences on network delay and network packet loss rate after the network tunnel is used, or whether IPv6 data can penetrate through a backbone network using an IPv4 protocol after the network tunnel is used is determined through a comparison result, and normal communication of each communication node is guaranteed.
In one example, by comparing the first network quality of service parameter with the second network quality of service parameter, it can be determined that each communication node can traverse the IPv4 backbone network through the 6to4 network tunnel, the communication service can be kept running normally, the network delay of the grid-scheduling data network does not exceed 20 milliseconds, and the network packet loss rate does not exceed 0.01%.
In this embodiment, by comparing the first network service quality parameter with the second network service quality parameter, the network performance of the power grid scheduling data network when the network tunnel is configured can be determined, and the advance prediction of the network performance in a network tunnel use scenario is realized.
