Abstract:By introducing an efficient statistical scheme for WAF traffic analysis processing which provides a mechanism for each processing Flow to dynamically adjust the processing capability, realizes dynamic adjustment processing capability, and realizes coordination adjustment processing capability and the synchronization mechanism between the various processing. On the other hand, in the traditional topology, drainage is started by the virtual network of the host machine or started by a stream serial thread with SDN. By introducing the high concurrent traction scheme in this study, the SDN traction Flow, strategy downward separation, and the concurrent protection of WAF are realized. Experimental results show that the scheme improves the accuracy of WAF protection and improves the WAF throughput.
