| Abstract: | As a result of combination of tomography technology, statistics theory and communication networking, network tomography is a novel technology about acquiring and processing information. In this paper, the cnception and mathematical model of network tomography network are briefly introduced. Next, the up-to-date research work on Link-Level Network Inference, topology identification and Origin-Destination Tomography are introduced and some efficient network tomography techniques are analyzed emphatically. Some valuable applications are explained and forecas ted. Finally, the research direction in the network tomography in the future is proposed. |
