The invention provides a network equalization method and a system for the packet transport of network traffic identifiers. The method comprises the steps of acquiring a network flow for packet transport; according to the acquired network flow for packet transport, establishing a network identification data table; searching flow identification parameters in the network identification data table, and judging whether the network flow for packet transport is consistent with the flow identification parameters of configuration parameters; when the network flow is not consistent with the flow identification parameters of the configuration parameters, pushing the early-warning information and conducting the corresponding correction and optimization operation. Through acquiring the network flow for packet transport, a network identification data table is formed by corresponding flow identification parameters. Therefore, the network bottleneck is identified by the corresponding early-warning information, and then a network equalization scheme is formulated. The network capacity expansion and optimization is reasonably developed. The service flow and the network resource matching degree are improved. The security and the resource utilization rate of the network are improved.
