<p>The invention provides a method and device of preventing attack for network equipment, and solves the problem that current communication network could not intelligently prevent attack. The method comprises obtaining a packet losing information of a flow overload, a resource information, a resource security information, and a flow restriction threshold of a network equipment. The flow restriction threshold of a service message is adjusted correspondingly based on the packet losing information of a flow overload and the comparative result of the resource information with the resource security information. Under the condition that the system resource is limited, the method and equipment adopt intelligent adjustment measures to increase the flow restriction threshold dynamically, thus improving the capacity of the network equipment to realize the best service disposing capacity. And under the condition that the system resource is overloaded, the method and equipment adopt intelligent prevention measures to decrease the flow restriction threshold dynamically, thus reaching the purpose of protecting equipment.</p> |
