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。
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.
