Description
Technical Field
The embodiment of the invention relates to the technical field of network simulation, in particular to a network simulation processing method, a network simulation processing device, electronic equipment and a storage medium.
Background
The network simulation is a high and new technology for simulating network behavior by using a mathematical modeling and statistical analysis method, and simulating the transmission of network traffic by establishing a statistical model of network equipment and network links, thereby obtaining network performance data required by network design and optimization. Conditions for network impairment simulation include the presence in a real wide area network: limited bandwidth, delay, packet loss, jitter, out of order, repeated packets, competing traffic, congestion, bit errors, etc. These conditions may reduce the performance of the application for network applications and are sometimes fatal.
The simulation method of the existing network mainly comprises the following three steps:
1) Simulation using a network simulator
At a basic level, the network simulator uses mathematical formulas to create network theory and a fully virtual network model. Simulators are software solutions, different types being available for different applications. Although they are mainly used for research and educational purposes, they can also be used as key test tools in network design and development. Testing a network in this manner may save time and money, but network simulators are not without limitation. These highly complex operations require a degree of experience and training to properly configure to obtain reliable results. In addition, network simulators are not practical because certain events cannot be expected independently of the physical network.
2) Simulation using a large network simulator
A network simulator (also called a WAN simulator) is used to test performance under a real network. These devices may also be used for quality assurance, concept verification or troubleshooting purposes. The network simulator is provided as a hardware or software solution that allows network architects, engineers and developers to accurately evaluate the application's responsiveness, throughput and end-user quality of experience before making changes or additions to the application system. By physically placing it between two LAN segments, the network emulator can accurately replicate the client-to-server WAN connection without the need for routers, modems, etc. Bandwidth constraints and impairments (e.g., packet loss, delay, and jitter) can then be applied to the mirrored network. Delays may be specified to simulate the remote transmission of data, the behavior and response of an application as if the client and server were physically separated in nature. Application performance and end user experience can then be observed, tested and verified in real time under such conditions. Such large network simulators are versatile and excellent in performance, but require high operating requirements, are expensive and are inconvenient to carry.
3) Simulation using network simulation software
Some network simulation software is installed on the PC to be converted into a network simulator. However, the PC has large volume and is inconvenient to carry; the network interface is less, the expansibility is poor, and the price of the network simulation software is more expensive.
In summary, in the prior art, simulation tests are only performed on a wired network, and a network simulation method for a wireless network is absent.

Detailed Description
The following describes the embodiments of the present invention further with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.
Fig. 1 shows a flow chart of a simulation processing method of a network according to the present embodiment, including:
s101, the network simulator determines the simulation transmission delay of the network according to the preset delay time, and determines the simulation packet loss rate of the network according to the preset packet loss rate.
The network simulator is small equipment for network simulation.
The delay time is preset time for simulating network transmission delay.
The packet loss rate is a preset proportion for simulating the network packet loss condition.
The simulated transmission delay is the transmission delay of the current simulated network.
The simulated packet loss rate is the packet loss rate of the current simulated network.
S102, receiving a service simulation instruction, generating a simulation data packet according to the service simulation instruction, and sending the simulation data packet to a test terminal according to the simulation transmission delay and the simulation packet loss rate.
Wherein the service simulation instruction is an instruction for performing service simulation.
The simulation data packet is a simulation data packet generated according to the service simulation instruction.
The network simulator is connected with the test terminal in a wired mode or a wireless mode, and sends the simulation data packet to the test terminal and receives the simulation data returned by the test terminal.
S103, receiving simulation data returned by the test terminal, and calculating according to the simulation data to obtain a simulation result.
The simulation data are returned data after the test terminal receives and processes the simulation data packet.
The simulation result is a result calculated from simulation data, such as network reliability.
For example, the small-sized network simulator provided in this embodiment is divided into three parts:
1) Wire part
Comprises 2-3 RJ45 wired ports. For connecting two networks (PCs) by wire.
2) Wireless part
Including WIFI interfaces. For connecting the wireless terminal(s) with the small network simulator.
3) Network simulation software
And installing kernel versions (built-in NetEm functions) of more than Linux2.6 and TC function modules. The phenomena of delay, packet loss, repetition, damage, disorder and the like of the network are simulated through commands.
The WiFi is a wireless network composed of a wireless access point AP (Access Point) and a terminal with a wireless access function. The AP is a bridge between the wired local area network and the wireless local area network, and any test terminal with a wireless access function can access the wired local area network and the wide area network after being connected with the AP. The test terminal may be a PC with a wireless network card, a PC with CPE access, a mobile phone, etc.
Compared with the connection structure of the simulation network provided by the prior art as shown in fig. 2, the connection structure of the simulation network provided by the embodiment is shown in fig. 3, and after the network is erected, the connection structure enters a linux system operation page of the small network simulator. The network simulation was performed according to the following commands: when performing the simulation of the delay transmission, the transmission of the ath0 network card is set to be delayed for 100ms to be sent, and the command is as follows: tc qdisc add dev ath0 root netem delay100 ms. The results obtained are shown in FIG. 4.
According to the embodiment, after the network simulator is connected with the test terminal in a wired mode or a wireless mode, simulation test is carried out according to the preset simulation transmission delay and the simulation packet loss rate, and the network simulator is low in price, convenient to carry, good in expansibility and applicable to wired and wireless networks.
Further, on the basis of the above method embodiment, determining, by the network simulator in S101, a simulated transmission delay of the network according to a preset delay time, specifically includes:
the network simulator determines the range of simulation transmission delay of the network according to the preset delay time and the delay fluctuation value;
correspondingly, in S102, the sending the simulated data packet to the test terminal according to the simulated transmission delay and the simulated packet loss rate specifically includes:
and generating target simulation transmission delay according to the range of the simulation transmission delay, and sending the simulation data packet to a test terminal according to the target simulation transmission delay and the simulation packet loss rate.
Specifically, in a real situation, the delay value is not so accurate as shown in fig. 4, and there is some fluctuation.
For example, the transmission of ath0 is set to be delayed by 100 ms.+ -.10 ms (any value between 90 and 110 ms) and sent as follows: tc qdisc add dev ath0 root netem delay100ms 10ms.
By simulating the delay value with fluctuation, more real network conditions can be reflected.

Wherein the emulation data package comprises the first emulation data package and the second emulation data package.
Specifically, to further enhance the randomness of the ripple delay value, the transmission of the ath0 network card is set to 100ms, and at the same time, about 30% of packets are transmitted with a delay of ±10ms:
tc qdisc add dev ath0 root netem delay 100ms 10ms 30％。
by simulating the delay value with random volatility, more realistic network conditions can be reflected.
Further, on the basis of the above method embodiment, in S102, the sending the simulated data packet to the test terminal according to the simulated transmission delay and the simulated packet loss rate specifically includes:
and sending the simulation data packet to a test terminal according to the simulation transmission delay, the simulation packet loss rate and a preset simulation packet loss success rate.
For example, when simulating network packet loss, the transmission of the ath0 network card is set to randomly drop 1% of data packets: tc qdisc add dev ath0 root netem loss 1%.
Further, setting the success rate of packet loss, setting the transmission of the ath0 network card to randomly drop 1% of data packets, wherein the success rate is 30%: tc qdisc add dev ath0 root netem loss1%30%.
By setting the success rate of randomly lost data packets and/or lost packets, more real network conditions can be reflected.
Further, on the basis of the above method embodiment, in S102, the sending the simulated data packet to the test terminal according to the simulated transmission delay and the simulated packet loss rate specifically includes:
and sending the simulation data packet to a test terminal according to the simulation transmission delay, the simulation packet loss rate, the preset simulation data packet repetition rate and the preset simulation data packet damage rate.
For example, when emulating packet duplication, the transmission of the ath0 network card is set to randomly generate 1% duplicate packets: tc qdisc add dev ath0 and root netem duplicate%.
In another embodiment, the packet corruption is simulated and the transmission of the ath0 network card is set to randomly generate 0.2% corrupted packets: tc qdisc add dev ath0, root netem corrupt, 0.2%.
By setting the repetition rate of the simulation data packet and/or the damage rate of the simulation data packet, more real network conditions can be reflected.
Further, on the basis of the above method embodiment, in S102, the sending the simulated data packet to the test terminal according to the simulated transmission delay and the simulated packet loss rate specifically includes:
immediately transmitting a third simulation data packet to a test terminal according to the simulation packet loss rate, and transmitting a fourth simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate;
wherein the simulation data packet includes the third simulation data packet and the fourth simulation data packet.
For example, to be able to simulate packet out-of-order, the transmission of the ath0 network card may be set to: 25% of the packets (50% correlation) would be sent immediately, with an additional delay of 10 seconds: tc qdisc add dev ath0 root netem delay 10ms reorder 25%50%.
By simulating the disorder of the data packets, the more real network condition can be reflected.
Further, on the basis of the above method embodiment, the simulation processing method of the network further includes:
determining new simulation transmission delay of the network according to the modified delay time, and determining new simulation packet loss rate of the network according to the modified packet loss rate;
correspondingly, in S102, the sending the simulated data packet to the test terminal according to the simulated transmission delay and the simulated packet loss rate specifically includes:
and sending the simulation data packet to a test terminal according to the new simulation transmission delay and the new simulation packet loss rate.
Specifically, the current emulation network can be restored or altered: if the simulation network is required to be recovered to be normal, only the monitoring needs to be deleted: tc qdisc del dev ath0 root netem delay 4s; if only the parameter values are changed: tc qdisc change dev ath0 root netem delay 4s.
Whether the network simulator sends the simulation data packet to the wired test terminal or the wired test terminal sends the simulation data packet to the network simulator, even the small network simulator communicates with the wireless test terminal, the network simulator is controlled by the commands.
The embodiment provides a network device with multiple network ports and WIFI function, which installs software with network simulation function, so that the network device becomes a small network simulator, the function of the network simulator is realized, the problems of high price, poor portability and poor expansibility of the simulation device in the prior art are solved, and the network device is also applicable to wired and WIFI networks.
