Active measurement is a common method for the network measurement. The implementation process of most active measurement tool can be divided into three parts: sending, receiving and processing packets. In this paper, we study the current active detection method of network performance in those three aspects and summarize the common procedure of the active measurement. A kind of development kit is designed to quickly implement various active measurement tool based on libnet and winpcap. The implementation of the active measurement tool is simplified by encapsulating all kinds of the operation required in the active measurement procedure and providing unified programming interface in the new design. As the experimental results suggest, the active measurement development kit is able to realize various function of the active measurement tool and greatly reduce the code compared with existing tool, and the efficiency is highly improved.
