Abstract: The technology of this application relates to a method for identifying a flow, where a communication device counts a received packet in a first filtering manner. When determining that a quantity of the received packets of the target flow is greater than or equal to a first threshold, the communication device marks, starting from a packet that exceeds the first threshold, a packet whose count is a multiple of m. When determining that a quantity of the received packets of the target flow is greater than or equal to a second threshold, the communication device counts, in a second filtering manner, a packet that is continuously received. When determining that a quantity of the received packets of the target flow is greater than or equal to a third threshold λ4, the communication device determines that the target flow is an elephant flow, and marks a packet that is continuously received.
