摘　　要：网络断层扫描是一种新的网络外部测量方法,与传统的网络内部测量方法不同,它是根据网络边缘的测量来推测网络内部属性或网络拓扑的,从而实现与网络结构或协议无关的网络测量。综述了网络断层扫描的基本概念、关键技术以及最新研究进展,最后提出了进一步研究的课题。Network tomography（NT） is a new measurement and inferring method, which is different from the traditional network internal measurement method, it infers the network attribute or identifies the network topology based on the measurement occurring on the edge of the network, implementing the network measurement in no connection with network constructor and protocol. This paper makes a survey of recent works of the network tomography, which presents the basic concept and key technology of the NT, and discusses research directions and open problems in this area are discussed.
