TRAFFIC PROCESSING METHOD, DEVICE AND SYSTEM

摘要

Disclosed is a traffic processing method, device and system, which are applied to a system comprising an elementary defence device and an advanced defence device, wherein the traffic cleaning capability of the advanced defence device is higher than that of the elementary defence device. The method comprises: a management and control device monitoring whether the load of an elementary defence device for cleaning the user traffic is greater than a first threshold; if a monitoring result is yes, the management and control device transferring the traffic processed by the elementary defence device to the advanced defence device for cleaning; the management and control device controlling the transfer of traffic which has been cleaned to a service processing device for processing. Thus different defence devices can be selected for traffic cleaning according to specific situations, reducing usage costs. At the same time, this series of operations are conducted without being perceived by a user, which does not need an additional operation from the user; thus the user experience is improved by way of dynamically scheduling a defence device.
