A network testing method and device

Abstract

The embodiment of the present invention provides a network testing method and device, which relate to the field of communication technology and are applied to the destination network equipment directly connected to the destination test terminal. The destination network equipment stores entries, and the above table entries record: IP address of the destination test terminal The corresponding relationship with the MAC address of the destination test terminal. Wherein, the above method includes: receiving a test message with the first IP address of the destination network device as the destination address, and the test message carries the first subnet mask of the first IP address. According to the first subnet mask, determine whether an IP address belonging to the same network segment as the first IP address is recorded in the entry. If yes, generate a response message whose destination address is the source address of the test message, and send the response message, so that the source network device determines the network test result based on the response message. Applying the network testing method provided by the embodiment of the present invention can improve the success rate of network testing.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a network testing method and device. Background technique [0002] In the prior art, the NQA (Network Quality Analyzer, network quality analysis) technology can be used to test the network performance of the network between the two test terminals. Specifically, the above two test terminals may be referred to as a source test terminal and a destination test terminal, respectively. The source test end sends a test packet to the destination test end, wherein the destination address of the test packet is the IP address of the destination test end, and the test packet can be sent to the destination test end after being forwarded by the network device. After receiving the test packet, the destination test end can feed back a response packet to the source test end. If the above-mentioned source test end can receive the above-mentioned response message, it means that t...

Problems solved by technology

[0003] However, the IP address of the destination test end may be a dynamic address. If the IP address of the destination test end changes, the test packets generated by the source test end based on the original IP address of the destination test segment are difficult to be sent to the destination test end, resulting in network test failure.
