Description

Technical Field

[0001] The present application relates to the technical field of network testing, and in particular to a broadband ad hoc network testing and file restoration method based on sample files. Background Art

[0002] Broadband ad hoc network is a dynamic network system that does not require fixed infrastructure and is usually used in a dynamic network environment that is rapidly deployed. Due to the characteristics of broadband ad hoc networks such as highly dynamic nodes and constantly changing topology, the stability of its network performance, transmission efficiency and data integrity face more stringent tests. In these application scenarios, testing network performance often involves actual application requirements of large-capacity data and high bandwidth, so it is crucial to conduct broadband ad hoc network test performance evaluation based on sample files (i.e., arbitrary files) with real payloads.

[0003] The current network testing tools on the market, such as Netperf and iperf, are mainly aimed at performance testing needs in ordinary network environments, and are usually used to test network parameters such as bandwidth, latency, and jitter. However, these tools do not support the use of sample files for testing, making it impossible for users to effectively verify the integrity and accuracy of broadband ad hoc network transmission. In addition, existing tools are also unable to restore the transmitted sample files after the test is completed, which limits the feasibility and practicality of using sample files in testing. Summary of the invention

[0010] In one embodiment, the server extracts payload data from stored data packets in batches by using a sliding window, and restores the sample file before the test based on the extracted payload data, including: The server dynamically plans the sliding window size based on the size of a single packet, and uses the sliding window to batch extract the payload data in the data packet by sorting the data packet sequence number, merges and splices all the extracted payload data, and restores the sample file before the test.

[0011] In one embodiment, the method further comprises: Based on the restored sample files, the network performance index results of the broadband ad hoc network are benchmarked and analyzed, and the performance of the broadband ad hoc network during data transmission is evaluated through benchmarking analysis.

[0019] In one embodiment, Figure 1 As shown, a broadband ad hoc network test and file restoration method based on sample files is provided, comprising the following steps: Step S1: The server sends test instructions to the sending end and the receiving end respectively through the broadband ad hoc network, and sends a sample file to the sending end.

[0020] Among them, by using sample files to conduct real load data network testing of broadband self-organizing networks, it is possible to more accurately simulate actual data transmission scenarios and improve the authenticity and effectiveness of broadband self-organizing network performance evaluation.

[0021] Step S2: The sender splits the sample file into payload data and encapsulates the sender information according to the size of a single packet, and sends all the data packets encapsulated by the sender to the receiving end through the broadband self-organizing network. After the data packet is sent, the start time and end time of the data packet are further reported to the server for storage through the broadband self-organizing network.

[0022] Specifically, the sender splits the sample file into payload data according to the size of a single packet, encapsulates each payload data into a data packet and sorts it, and encapsulates the sender timestamp, sender IP, sender port and data packet sequence number into the data packet.

[0023] Furthermore, after the information encapsulation of the sender is completed, a test script of the traffic generator (MGEN) is written, all the data packets encapsulated by the sender are loaded into the test script, and the traffic generator is used to parse the test script and send all the data packets encapsulated by the sender to the receiving end through the broadband ad hoc network.

[0024] Among them, by splitting and encapsulating data packets, the standardization and manageability of data transmission are ensured, which helps to improve the reliability of the test process. And by recording the time information of the sent and received data packets, various network performance indicators such as delay, packet loss rate, transmission rate, packet group time difference, etc. can be analyzed in detail, so that users can effectively verify the integrity and accuracy of broadband ad hoc network transmission.

[0025] Step S3: The receiving end records the received data packets one by one and encapsulates the receiving end information, and reports all the encapsulated data packets of the receiving end to the server for storage through the broadband ad hoc network.

[0026] Specifically, the receiving end records the received data packets one by one, and encapsulates the receiving end timestamp, receiving end IP and receiving end port into the data packet. After the receiving end information encapsulation is completed, all the receiving end encapsulated data packets are reported to the server for storage through the Kafka message middleware in the broadband ad hoc network.

[0027] Furthermore, the server stores the data packets reported by the receiving end in the elastic search search engine.

[0028] Step S4: After the test of the sending end and the receiving end is completed and the data reporting is completed, the server uses a time window to perform statistical analysis on the stored data to obtain the network performance indicator results of the broadband ad hoc network; the server uses a sliding window to batch extract the payload data in the stored data packets, and restores the sample file before the test based on the extracted payload data.

[0029] Specifically, after the test of the sending and receiving ends is completed and the data is reported, the server dynamically plans the time interval according to the test duration to divide the time window, and uses the time window to perform statistical analysis on the stored data to obtain the network performance indicator results of the broadband ad hoc network; among them, the network performance indicator results include latency, packet loss rate, transmission rate, packet group time difference and total number of data packets.

[0030] The server dynamically plans the sliding window size based on the size of a single packet, and uses the sliding window to batch extract the payload data in the data packet by sorting the data packet sequence number, merges and splices all the extracted payload data, and restores the sample file before the test.

[0031] Restoring the sample files can avoid the limitation of feasibility and practicality of using the sample files in network performance testing. Furthermore, the server can also benchmark and analyze the network performance index results of the broadband ad hoc network based on the restored sample files, and evaluate the performance of the broadband ad hoc network in the data transmission process through benchmarking analysis, which is conducive to optimizing network performance.
