Description
Technical Field
The embodiment of the invention relates to the technical field of network simulation, in particular to a simulation processing method and device of a network, electronic equipment and a storage medium.
Background
Network simulation is a high and new technology which simulates network behavior by using a mathematical modeling and statistical analysis method, and simulates the transmission of network traffic by establishing a statistical model of network equipment and network links, thereby acquiring network performance data required by network design and optimization. The conditions of the network impairment simulation include those present in a real wide area network: limited bandwidth, delay, packet loss, jitter, misordering, duplicate packets, competing traffic, congestion, bit errors, and the like. These conditions can degrade the performance of the application for network applications and can even be fatal at times.
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, and different types can be used for different applications. Although they are used primarily for research and educational purposes, they can also serve as key test tools in network design and development. Testing the network in this manner saves time and money, but the network simulator is not without limitation. These highly complex operations require a degree of experience and training to properly configure to achieve reliable results. In addition, network simulators are not practical because certain events cannot be expected independently of the physical network.
2) Simulation using large-scale network simulator
Network simulators (also known as WAN simulators) are used to test performance under real networks. These devices may also be used for quality assurance, concept verification or troubleshooting purposes. Network emulators are provided as hardware or software solutions that allow network architects, engineers and developers to accurately assess the responsiveness, throughput and end-user quality of experience of an application before making changes or additions to the application. By placing it physically between the 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 can be specified to simulate transmitting data over long distances, the behavior and response of the application as if the client and server were physically separated. Application performance and end-user experience can then be observed, tested and verified in real-time under such conditions. The large-scale network simulator has multiple functions and excellent performance, but has high operation requirement, high price and inconvenient carrying.
3) Simulation using network simulation software
Some network simulation software is installed on the PC, so that the PC is converted into a network simulator. But the PC is large in volume and inconvenient to carry; the network interface is few, the expansibility is poor, and the price of the network simulation software is expensive.
In summary, the prior art only performs simulation tests on wired networks, and lacks a network simulation method for wireless networks.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows a schematic flow chart of a simulation processing method of a network provided in this 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 a small device 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 simulation transmission delay is the transmission delay of the current simulation network.
And the simulation packet loss rate is the packet loss rate of the current simulation 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.
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 the simulation data returned by the test terminal, and calculating according to the simulation data to obtain a simulation result.
And the simulation data is returned after the test terminal receives and processes the simulation data packet.
The simulation result is a result calculated from the simulation data, such as network reliability.
For example, the small network simulator provided by the embodiment is divided into three parts:
1) wired part
Includes 2-3 RJ45 cable ports. For connecting two networks (PCs) by wire.
2) Wireless part
Including the WIFI interface. For connecting the wireless terminal(s) (1 or more) with the small network simulator.
3) Network simulation software
And installing a kernel version (built-in NetEm function) of Linux2.6 or more and a TC function module. 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 can be a PC with a wireless network card, a PC with access to CPE, a mobile phone and the like.
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 as shown in fig. 3, and after the network is set up, the network enters the linux system operation page of the small network simulator. Network simulation is carried out according to the following commands: when the simulation of delayed transmission is performed, the transmission of the ath0 network card is set to be transmitted with a delay of 100 milliseconds, and the commands are as follows: tc qdisc add dev ath0 root netem delay100 ms. The results obtained are shown in FIG. 4.
In the embodiment, after the network simulator is connected with the test terminal in a wired or wireless mode, the simulation test is performed according to the preset simulation transmission delay and the simulation packet loss rate, so that the price is low, the carrying is convenient, the expansibility is good, and the network simulator is also suitable for wired and wireless networks.
Further, on the basis of the above method embodiment, the determining, by the network simulator, the simulated transmission delay of the network according to the preset delay time in S101 specifically includes:
the network simulator determines the simulation transmission delay range of the network according to the preset delay time and the delay fluctuation value;
correspondingly, in S102, the sending the simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate specifically includes:
generating a 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.
In particular, in a real situation, the delay value is not as precise as shown in fig. 4, with some fluctuation.
For example, the transmission of ath0 is set to be sent with a delay of 100ms ± 10ms (any value between 90 ms and 110 ms), and the following commands are ordered: tc qdisc add dev ath0 root netem delay100ms 10 ms.
By simulating a delay value with volatility, a more real network situation can be reflected.

and sending a first simulation data packet with a preset proportion in the simulation data packets to a test terminal according to the simulation packet loss rate, and sending a second simulation data packet to the test terminal according to the target simulation transmission delay and the simulation packet loss rate.
Wherein the emulation data packet comprises the first emulation data packet and the second emulation data packet.
Specifically, to further enhance the randomness of the fluctuating delay values, the transmission of the ath0 network card is set to 100ms, while approximately 30% of the packets are transmitted with a delay of ± 10 ms:
tc qdisc add dev ath0 root netem delay 100ms 10ms 30％。
by simulating a fluctuating delay value with randomness, a more realistic network situation can be reflected.
Further, on the basis of the above method embodiment, the sending the simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate in S102 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 the simulation network loses packets, the transmission of the ath0 network card is set to randomly lose 1% of the packets: tc qdisc add dev ath0 root netem loss 1%.
Further, the success rate of packet loss is set, the transmission of the ath0 network card is set to randomly drop 1% of data packets, and the success rate is 30%: tc qdisc add dev ath0 root netem loss 1% 30%.
By setting the success rate of the data packets which are lost randomly and/or the packet loss, the more real network condition can be reflected.
Further, on the basis of the above method embodiment, the sending the simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate in S102 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, in the case of duplicate simulation packets, the transmission of ath0 network cards is set to randomly generate 1% duplicate packets: tc qdisc add dev ath0 root netem duplicate 1%.
In another embodiment, simulating packet corruption, 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, a more real network situation can be reflected.
Further, on the basis of the above method embodiment, the sending the simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate in S102 specifically includes:
immediately sending a third simulation data packet to a test terminal according to the simulation packet loss rate, and sending a fourth simulation data packet to the test terminal according to the simulation transmission delay and the simulation packet loss rate;
wherein the emulation data packet includes the third emulation data packet and the fourth emulation data packet.
For example, to be able to emulate packet misordering, the transmission of the ath0 network card may be set to: 25% of the packets (50% correlated) will be sent immediately, the other delays 10 seconds: tc qdisc add dev ath0 root netemdelay 10ms reorder 25% 50%.
By simulating the disorder of the data packets, a more real network situation can be reflected.
Further, on the basis of the above method embodiment, the simulation processing method for a 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 simulation data packet to the test terminal according to the simulation transmission delay and the simulation 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.
In particular, the current simulation network can be restored or modified: if the simulation network is required to be recovered to normal, only monitoring needs to be deleted: tc qdisc del dev ath0 root netem delay 4 s; if only the parameter values are changed: tc qdiscchange dev ath0 root netem delay 4 s.
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 simulation data packet is controlled by the commands.
The embodiment provides a multi-network-port network device with a WIFI function, software with a network simulation function is installed on the network device, the network device becomes a small network simulator, the functions of the network simulator are realized, the problems of high price, poor portability and poor expansibility of simulation equipment in the prior art are solved, and the multi-network-port network device is also suitable for wired and WIFI networks.
