Claim 8:
9. A network management method configured to analyze a data flow, wherein the network management method comprises:
receiving a packet of the data flow;
computing, by using a first hash algorithm, a first digest value of the packet according to a packet attribute in response to the packet satisfying a dropping event;
computing, by using a second hash algorithm, a second digest value of the packet according to the packet attribute in response to the packet satisfying the dropping event;
computing a plurality of identification codes of the packet respectively according to the first digest value and the second digest value of the packet, and searching a plurality of status values associated with the plurality of identification codes in a plurality of lookup tables respectively, so as to determine whether the dropping event of the data flow is recorded;
recording a packet content in a monitoring event in response to determining that at least one of the following conditions is met: (1) a first status value of the plurality of status values does not satisfy a control value, and (2) a second status value of the plurality of status values does not satisfy the control value; and
changing the first status value of a first lookup table of the plurality of lookup tables to be the control value and changing the second status value of a second lookup table of the plurality of lookup tables to be the control value,
wherein the first hash algorithm is different from the second hash algorithm, and the first digest value is different from the second digest value.
