IPv6 target positioning method based on time delay constraint and adjacent sequence

The invention provides an IPv6 (Internet Protocol Version 6) target positioning method based on time delay constraint and an adjacent sequence. According to the method, multiple detection sources are used for carrying out mass detection to obtain path information from the detection sources to a target, a time delay-distance conversion relation is obtained through the path information obtained through detection, and then network time delay and a network topology structure are used for restraining the target to be within a coarseness range. And finally, according to the target address and the landmark address in the constraint area, an IPv6 adjacent sequence is judged, and the target is positioned based on the adjacent sequence. 本发明提供一种基于时延约束和邻近序列的IPv6目标定位方法。该方法使用多探测源进行大量探测获取探测源到目标的路径信息，并利用探测所获取的路径信息获取一个时延-距离转换关系，再利用网络时延和网络拓扑结构将目标约束至一个粗粒度的范围内，最后依据目标地址和约束区域内的地标地址，判定IPv6邻近序列并基于邻近序列对目标进行定位。
