Described statistic unit, the receiving terminal of quantity and described second channel that the transmitting terminal also for adding up described second channel in described second Preset Time sends packet receives the quantity of packet;

Described Alarm Unit, the receiving terminal that transmitting terminal for the described second channel when described statistic unit statistics sends the described second channel that the quantity of packet and described statistic unit are added up receive the quantity of packet unequal time, send warning information and generate log recording.

6. a method for applied in network performance test, is characterized in that, comprising:

Speed first passage being sent packet in the first Preset Time is progressively reduced to zero by port speed, and synchronous speed second channel being sent packet is progressively increased to described port speed by zero, the speed sum that the speed of wherein said first passage transmission packet and described second channel send packet is described port speed;

The receiving terminal of quantity and described first passage that the transmitting terminal adding up described first passage in described first Preset Time sends packet receives the quantity of packet;

When the quantity that the receiving terminal of quantity and described first passage that the transmitting terminal of described first passage sends packet receives packet is unequal, sends warning information and generate log recording.

7. method according to claim 6, it is characterized in that, described warning information comprises packet loss quantity and the temporal information of packet loss occurs, described packet loss quantity is the difference that the receiving terminal of described first passage receives between quantity that the quantity of packet and the transmitting terminal of described first passage send packet, and the temporal information of described generation packet loss comprises described first passage and starts to send the moment that moment of packet and described first passage stop sending packet.

8. the method according to claim 6 or 7, is characterized in that, the frame structure of described packet comprises the distinguishing identifier for distinguishing described first passage and described second channel.

9. the method according to any one of claim 6-8, is characterized in that, described first passage and described second channel independently transmit and receive data bag separately.

10. the method according to any one of claim 6-9, it is characterized in that, when the quantity that the receiving terminal of quantity and described first passage that the transmitting terminal of described first passage sends packet receives packet is unequal, warning information is sent and after generating log recording, described method also comprises described:

The speed described second channel being sent packet in the second Preset Time is progressively reduced to zero by port speed, and synchronous speed first passage being sent packet is progressively increased to described port speed by zero;

The receiving terminal of quantity and described second channel that the transmitting terminal adding up described second channel in described second Preset Time sends packet receives the quantity of packet;

When the quantity that the receiving terminal of quantity and described second channel that the transmitting terminal of described second channel sends packet receives packet is unequal, sends warning information and generate log recording.
