ABSTRACT:
A method for measuring network performance is disclosed to solve the problem in active network performance measurement that a measurement point on receiving a packet is unable to determine the source of the packet after the network address translation (NAT). The method includes that a first measurement point constructs a probe packet containing address information about the first measurement point in a data field thereof based on a measurement instruction and sends the probe packet to a second measurement point via a NAT device for translating the network address, and the second measurement point receives the probe packet and determines the source of the packet according to the address information in the packet; and finally calculates network performance metrics, according to related information in the probe packet. A network system is also disclosed.
