Embodiment Construction
[0042] The invention will be described in further detail below in conjunction with the accompanying drawings.
[0043] Such as figure 1 As shown, the present invention provides a mixed packet marking traceability system suitable for SDN networks. The system mainly combines abnormal behavior detection and data traceability technology to selectively mark or record data packets to achieve data traceability. The purpose of improving the accuracy and efficiency of data traceability. The system is mainly composed of four modules: regional agent module, anomaly detection module, data processing module and traceability management module, including as follows:
[0044] 1. Regional agent module
[0045] The regional agent module manages all related information of switches in a specific network area. Due to the complexity of the SDN network topology, the regional agent module in each traceability system is only responsible for managing part of the information of all switches in a speci...
