File transfer protocol based network throughput testing approach

Abstract

In the invention, the sending party sets up buffer area, and fills data as data source of simulation file; and the receiving party creates buffer area to receive data. After test is started, the method executes steps: specifying remote server file (RSF), or determining route, name and size of RSF; calculating transmission positions of starting and stopping each thread; creating prearranged number of transmission thread, and starting up execution of transmission; obtaining size of transmitted data (TD) and transmission time (TT) of each thread, making statistics for throughput; when TD reach specified size, or TT reaches specified time, or user stops testing, the method stops each transmission thread. Making the most of network capacity, the invention eliminates unnecessary interference from reading/writing files so as to reflect actual throughput of network precisely and raise reliability. Moreover, automation control increases easy to use the test device and efficiency of test.

Description

technical field [0001] The invention relates to the field of communication network performance testing, in particular to a method for testing network throughput based on a file transfer protocol. Background technique [0002] Usually, in order to locate network faults and optimize the network, it is necessary to test the performance of the network. The network performance indicators mainly include throughput, response time, delay, jitter, and packet loss. The throughput refers to the maximum amount of data that passes through the network per unit of time without packet loss, and is measured in bits or bytes per second. Throughput is a comprehensive reflection of network performance. [0003] Throughput is closely related to network protocols, because different network protocols have different encapsulation formats, checksums, and sending and receiving processing of data packets. FTP (File Transfer Protocol) is a standard for file transfer in the network, and is an importan...

[0011] 5. The arrival of message segments may be out of order. In this case, TCP will reorder the received data and deliver the received data to the upper layer in the correct order.

[0012] 6. The data message will be repeated, so the receiving end of TCP must discard the repeated data

[0016] 1. Throughput is the maximum data rate of the network without packet loss, and the general file transfer system is not aimed at measuring throughput. Even if multi-threaded transfer is supported, one thread transfers part of the file data, the specified part The data transmission completion thread also ends, so the maximum rate cannot be reflected throughout the test process. For file uploads, it is more difficult to accurately test the throughput because the system does not support multi-threaded transmission of the same file.

[0017] 2. File reading and writing is not a part of network transmission, but it takes up processing time. Especially when the network speed is fast, the disk system is slow and the test equipment has limited memory, the file reading and writing time is more considerable than the network transmission time. Test The result does not exclude this part of the time, making
