Embodiment
As shown in Figure 1, the invention discloses the method for testing of the many DUT of a kind of identical ip addresses, comprise terminal, tester and multiple DUT, terminal is connected with the network interface 0 of tester, multiple DUT is connected to n respectively one by one with the network interface 1 of tester, and as one embodiment of the invention, this terminal can be PC.
This method of testing also comprises:
Setting procedure, the IP number of the network interface 0 of tester is more than or equal to n+1, and wherein, n represents DUT quantity, and wherein IP0 is the IP of tester itself, IP1 to n is DUT virtual IP address, each IP corresponding DUT respectively of network interface 0;
Conversion accessing step, assuming that DUT IP is X, the network interface 1 of tester is X+1 to X+n to the IP of n, and the access of all IP m to network interface 0 is converted to the access to DUT IP X, and ties up packet and exported by network interface m.
Instrument runs Linux system, by configuration routing table and policybased routing, the access of all IP m to network interface 0 is converted to the access to DUT IP X, and ties up packet and flowed out by network interface m, like this access to the DUT that network interface m connects just has been converted into the access of IP m.By such mapping one by one, each IP address just corresponding DUT of difference of network interface 0, just can access corresponding DUT by the different virtual IP address of access concerning PC.
Some DUT needs PC upload file to DUT, and then DUT restarts and enters test mode, and the IP address before and after restarting can change (set before TFTP IP as Y), and conventional method PC needs to increase an IP again and serves for TFTP.
File transfer step is comprised in method of testing of the present invention, the carrying out of TFTP port is bound, to the IP address field Y+N(before network interface 1-n increase TFTP state, this is operating as inner realization simultaneously, to user transparent), virtual IP address n can be directly used when such user uploads, inner route, by the IP Y of the access map of TFTP port to TFTP state, can reduce user's configuration like this.
Some DUT needs to download startup file in the uboot stage from PC and could start and enter test mode (set server ip that uboot needs are accessed as Z), this stage needs first to send the mac address that ARP message looks into lower Y due to uboot, and the uboot of some version needs to receive arp response content mates just identification completely, because instrument itself does not have IP Z, so just have no idea to respond ARP, uboot failed download will be caused.For this reason, in file transfer step of the present invention, monitor the ARP message that network interface 1-n receives, send if ARP content is uboot, then initiatively send the arp response message that uboot needs.
TFTP is the simple protocol of a transfer files, and it realizes based on udp protocol.
Why the BIOS boot of the similar pc of uboot, be Uboot, is because the meaning of universal, and namely general boot, Uboot can guide the CPU of X86, also can guide the CPU of ARM, also has the CPU of PowerPC, MIPS and so on.
The invention also discloses the test macro of the many DUT of a kind of identical ip addresses, comprise terminal, tester and multiple DUT, terminal is connected with the network interface 0 of tester, and multiple DUT is connected to n respectively one by one with the network interface 1 of tester, as one embodiment of the invention, this terminal can be PC.
In test macro of the present invention, also comprise:
Setting module, the IP number for the network interface 0 making tester is more than or equal to n+1, and wherein, n represents DUT quantity, and wherein IP0 is the IP of tester itself, IP1 to n is DUT virtual IP address, each IP corresponding DUT respectively of network interface 0;
Conversion access modules, for supposing that DUT IP is X, the network interface 1 of tester is X+1 to X+n to the IP of n, and the access of all IP m to network interface 0 is converted to the access to DUT IP X, and ties up packet and exported by network interface m.
This test macro also comprises document transmission module, binds in document transmission module to TFTP port, the IP address field Y+N before increasing TFTP state simultaneously to network interface 1-n.
In described document transmission module, inner route is by the IP Y of the access map of TFTP port to TFTP state.
In described document transmission module, monitor the ARP message that network interface 1-n receives, send if ARP content is uboot, then initiatively send the arp response message that uboot needs.
Present invention achieves single PC, the DUT of the multiple identical IP of single tester test, network connection topologies is simple, greatly reduces production cost simultaneously; In 4 conventional DUT test environments, this invention just decreases the cost of 3 PC, and simultaneously owing to only needing a computer, operation also becomes simple, improves the efficiency of production line.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
