A method for measuring network performance is provided in the present invention. The method is used to obtain a network address binding relationship of a measured flow from a network address translation (NAT) device between two measurement points, and configure flow description of the measured flow and the network address binding relationship to the measurement points. The measurement point extracts a target packet belonging to the measured flow according to the flow description or according to the flow description and the network address binding relationship, uses the network address binding relationship to make different measurement points create the same packet identification (ID) for the same packet, and generates and reports a packet abstract data according to a flow ID and the packet ID. Then, network performance indexes are calculated according to the packet abstract data reported by the measurement points. A network system is further provided in the invention.
