Step S202: obtain the first sending time slots between the first packet and the second packet according to the packet capturing file obtained from network traffics.
Time slot refers to any periodicity period that can uniquely identify and define, and the serial being the gap information being exclusively used in some single passages, from multiplexing part, is a timeslice in time division multiplexing (TDM).The first sending time slots between the first packet and the second packet can be obtained according to packet capturing file.Wherein, the first packet and the second packet are two packets adjacent in network traffics, and the first packet can belong to identical data flow with the second packet, also can belong to different data flow.
Step S203: according to described first sending time slots and belonging to described first packet data flow preset multiplication factor obtain the second sending time slots.
In order to can network environment that is virtually reality like reality, when the packet structure test packet for same data flow, be that the multiplication factor preset according to identical data flow carries out constructing.Therefore, according to the first sending time slots and belonging to the first packet data flow preset multiplication factor can obtain the second sending time slots, namely the second sending time slots equals the multiplication factor that the first sending time slots is preset divided by data flow belonging to the first packet, and namely the second sending time slots is the business of described first sending time slots and described multiplication factor.

Step S205: the cryptographic Hash of the stream sequence number of data flow belonging to described first packet of the high byte position of the mark of the IP head of N number of test packet of described structure write, and recalculate the School Affairs of the IP head of described test packet.
Conveniently receiving terminal carries out the identification of data flow, the cryptographic Hash of the stream sequence number of data flow belonging to the first packet is written to the high byte position (such as, the identification division of table 2) of the mark of the IP head of N number of test packet.Because IP head is written with the cryptographic Hash of stream sequence number, therefore need the School Affairs (such as, the header checksum of table 2) of the IP head recalculating test packet.
In this way, test macro is when receiving the test packet that equipment under test forwards, can according to the high byte position of the mark of the IP head of the test packet received, determine that this test packet is the test packet belonging to which data flow very soon, data statistics is carried out to facilitate the test packet to receiving, thus do not need again to identify that received test packet is the test packet belonging to which data flow again, improve the efficiency of data statistics.
Step S206: if the protocol type of described first packet is multichannel agreement, while using described N number of IP address to replace the source IP address of described first packet, then synchronously replace the IP address of useful load part in described first packet, and recalculate the School Affairs of the data division of described N number of test packet.
If the protocol type of the first packet is multichannel agreement, then also include IP address information at the data division of the first packet, therefore, for the first packet that protocol type is multichannel agreement, N number of IP address is used to replace the source IP address of this first packet (such as, the source IP address of table 2) time, in synchronous replacement first packet, the IP address of useful load part (such as, the data division of table 1), and the School Affairs recalculating the data division of N number of test packet (such as, the data division of table 1), like this, N number of test packet can be constructed.
Because in test packet, the IP address of useful load part is also synchronously replaced, in this way, make equipment under test can correctly process the multichannel associated services of application layer according to the IP address of useful load part in test packet, thus the applied environment of real network can be simulated more truly.
Wherein, step S205 and step S206 does not have obvious sequencing relation, can select an execution yet.

Such as, the first sending time slots is 1 second, and the multiplication factor that data flow belonging to the first packet is preset is 10 times, then the second sending time slots is 0.1 second, namely within every 0.1 second, sends a test packet.
Step S208: receive the test packet that described equipment under test forwards.
After equipment under test receives test packet, forwarded by the test packet of reception, therefore test macro receives the test packet that equipment under test forwards, so that test macro obtains the test performance of equipment under test.
Step S209: obtain test result according to the test packet received.
