Data tracing method and device

The invention discloses a data traceability method and device, relates to the technical field of computers, and solves the problems that manual participation is needed in the early stage of the current data traceability process, the efficiency is too low, and unnecessary expenses are brought to traceability work due to traceability of redundant fields or reserved fields in a database due to the design problem of the database. The data tracing method comprises the steps of obtaining a data packet mirror image of network equipment, analyzing the data packet mirror image, determining structured data of the data packet mirror image, and generating tracing data of the network equipment according to packet header data. 本发明公开了一种数据溯源方法和装置，涉及计算机技术领域，解决了目前数据溯源过程前期需要人工参与效率过低的问题，以及由于数据库设计问题导致对数据库中冗余字段或保留字段溯源而为溯源工作带来不必要的开销的问题。该数据溯源方法包括：获取网络设备的数据包镜像，解析数据包镜像，确定数据包镜像的结构化数据，根据包头数据，生成网络设备的溯源数据。
