In step S2, the first terminal apparatus is embedded with a test program, and a test parameter is set by the test program accordingly, enabling the first terminal apparatus to transmit a data packet according to a setting value of the test parameter. In the exemplary embodiment, the test program is a packet Internet groper, i.e., a conventional Ping instrument, and the test parameter at least comprises one selected from a group consisting of a number of test data packet needed to be transmit, a size of the test data packet, and a receiving rate of the test data packets in a single test. For example, the size of the test data packets can be set to a size that Windows supports, the first terminal apparatus is designed to transmit N (=1000) test data packets, each of which has 1280 bytes, in a single test, and the network connection apparatus is judged to be a qualified product if a receiving rate of the test data packets received by the second terminal apparatus is larger than 90%. Note that the size of the testing data packet is defined according to a standard constituted by Internet Engineering Task Force (IETF), and can have a size of 64, 128, 256, 1024, 1280 or 1518. Whether a test result is successful or not is defined according to the standard constituted by Internet Engineering Task Force (IETF). Then proceed to step S3.
In step S3, a packet capturing program and an execution parameter are embedded in the second terminal apparatus, enabling the second terminal apparatus to acquire the test data packet according to a setting value of the executive parameter. In the exemplary embodiment, the packet capturing program is an ethereal packet acquiring software. In an actual application process, an internet protocol type in the software is set to be Internet control Message Protocol (ICMP), and a type value of ICMP rule is set to be 8. Under the ICMP rule, the second terminal apparatus automatically provides a reply to indicate that the test data packets are received provided after receiving the test data packets. After such a setting process is completed, the second terminal apparatus runs the packet acquiring software to receive the test data packets. Next proceed to step S4.
In step S4, when executing the test program the first terminal apparatus transmits a group of test data packets to the second terminal apparatus, and counts a number of the data packets that have been transmitted until the number of the transmitted test data packets is equal to the setting value of the test parameter, which is set by the test program previously. In the exemplary embodiment, the first terminal apparatus is designed to execute the Ping instruction and transmit N (=1000) test data packets, each of which has 1280 bytes, in a single test to a specified address, and count a number M of test data packets that have been transmitted in the single test. The number M is added by one every time when one test data packet is transmitted by the first terminal apparatus until the number M is equal to the number N, that is 1000. Then proceed to step S5. In step S5, the second terminal apparatus executes the packet capturing program to acquire the test data packets transmitted from the first terminal apparatus, and counts a number P of the test data packets that have been received by the second terminal apparatus. In the exemplary embodiment, after receiving the test data packets the second terminal apparatus returns information representing that the test data packets have been received by the second terminal apparatus, and counts the number P. The number P is added by one every time when the second terminal apparatus receives one test data packet until the number P is equal to N, that is 1000, which means that test is completed. Then proceed to step S6. In step S6, the test parameter set by the test program is compared with the number P of the test data packets that have been received by the second terminal apparatus and counted by the packet capturing program, and a receiving rate of the test data packets is calculated. In the exemplary embodiment, the second terminal apparatus is assumed to have received 950 test data packets, i.e., P=950, which means that the receiving rate of the test data packet is 95% (P/M). Then proceed to step S7.
In step S7, the data receiving efficiency of the first connecting port and the second connecting port assembled in the network connection apparatus that has been tested is judged according to the receiving rate of the test data packets. In the exemplary embodiment, the receiving rate is 95%, which is larger than a predetermined receiving rate of 90%, so the data receiving efficiency of the connecting ports assembled in the network connection apparatus is quite excellent. In addition, such a test result can be recorded in the terminal apparatuss for future reference.
