Topology inference is one of the main applications in network tomography, and network topology can be inferred by end-to-end measurement by using tomography. This paper discusses topology inference technologies based on network tomography, the measurement methods and topology inference methods. The measurement methods and topology inference methods are analyzed integrally, and the difficulties in topology inference are concluded. The next step researches on network topology inference are discussed.
