    摘要： A method of automatically diagnosing operation of a communication network, the method comprising: collecting, during a plurality of time periods, a plurality of Layer-4 protocol statistics for Layer-4 network connections each having a first endpoint at one of one or more client devices, wherein data transmitted for each of the Layer-4 network connections traverses the communication network; determining a first network performance indicator, based on the Layer-4 statistics collected during a first time period included in the time periods and the Layer-4 statistics collected during a second time period included in the time periods and neither overlapping nor consecutive with the first time period; determining whether the communication network has experienced a performance issue based on the first network performance indicator; and causing a diagnostic action, a corrective action, or a maintenance action to be performed based on the determination whether the communication network has experienced a performance issue, wherein: the collecting a plurality of Layer-4 protocol statistics includes collecting TCP statistics for TCP connections when a packet is transmitted for the TCP connection; each of the Layer-4 network connections for which the Layer-4 protocol statistics are collected has a second endpoint at a network node; and the collecting is performed at the network node.
