【摘要】 网络层析成像技术作为通信网络、层析成像技术和统计学理论相结合的产物,是一种全新的网络链路级参数推理、拓扑结构识别和OD(Origin-Destination)流估计的技术。在简要介绍网络层析成像的基本概念和数学模型的基础上,本文从网络链路级参数的推理、网络拓扑结构识别和OD流的估计3方面介绍了网络层析成像的研究现状,分析和展望了一些有价值的新发展,并指出了下一步的研究方向。更多还原

【Abstract】 As a result of combination of tomography technology,statistics theory and communication networking,net- work 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 ef- ficient 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.更多还原
