The present invention discloses a method for measuring and evaluating network burst damage event, wherein the method comprises the following steps: passive perceiving and active detecting burst event; filtering and analyzing after merging the result; dividing the event grade according to the merging result, realizing the positioning to the fault reason; determining whether an adjustment of protocol mechanism should be executed according to the grade; and checking the whole condition of adjusted network for ensuring the correctness. The invention also provides a system for measuring the network burst damage event. The system comprises a router control module, an array management algorithm module, a network management module and an off-line calculating module. The problem to be settled by the invention is cause that the router has a flow perceiving capability, realize whether the full-network link and node operate normally and whether the burst damage event is generated. The result is notified in time for adjusting the protocol mechanism. The invention provides criterion for the protocol adjustment thereby increasing the usability and reliability of network node and link and finallyguaranteeing the service quality of network.
