Brief description of the drawings
Fig. 1 is the principle of the present invention block diagram.
Embodiment
As shown in Figure 1, the invention discloses a kind of test method of the identical more DUT of IP address, including terminal, tester and
Multiple DUT, terminal are connected with the network interface 0 of tester, and multiple DUT are connected one by one respectively with the network interface 1 of tester to n, as
One embodiment of the invention, the terminal can be PC.
The test method further includes：
Setting procedure, the IP numbers of the network interface 0 of tester are more than or equal to n+1, wherein, n represents DUT quantity, and wherein IP0 is survey
It is DUT virtual IP addresses to try instrument IP in itself, IP1 to n, and each IP of network interface 0 corresponds to a DUT respectively；
Change accessing step, it is assumed that DUT IP are X, and the IP of network interface 1 to the n of tester are X+1 to X+n, will
The access of all IP m to network interface 0 is converted to the access to DUT IP X, and ties up data packet and exported by network interface m.
Instrument runs Linux system, by configuring routing table and policybased routing, by the access of all IP m to network interface 0
The access to DUT IP X is converted to, and ties up data packet and is flowed out by network interface m, so access to IP m has been converted into pair
The access for the DUT that network interface m is connected.Mapping one by one in this way, each IP address of network interface 0 just correspond to a DUT respectively,
For PC corresponding DUT can be accessed by accessing different virtual IP addresses.
Some DUT need PC to upload files to DUT, and then DUT restartings enter test mode, and before and after restarting
IP address can change（If IP is Y before TFTP）, conventional method PC needs to be further added by an IP and serviced for TFTP.
Include file transmitting step in the test method of the present invention, to binding for TFTP ports, while give network interface
IP address section Y+N before 1-n increase TFTP states（This operation is realized to be internal, transparent to user）, such user can when uploading
Virtual IP address n is directly used, inside is route the IP Y of the access map of TFTP ports to TFTP states, can so reduce user
Configuration.
Some DUT needs can just launch into test mode from PC download startup files in the uboot stages and (set uboot need
The server ip to be accessed is Z), this stage needs first to send the mac addresses that ARP messages look into lower Y due to uboot, and some
The uboot of version need to receive arp response content matches just identification completely, since instrument does not have IP Z in itself, do not have thus
There is method to respond ARP, may result in uboot failed downloads.For this reason, in the file transmitting step of the present invention, network interface 1-n is monitored
Received ARP messages, send if ARP contents are uboot, actively send the arp response message of uboot needs.
TFTP is the simple protocol of a transmission file, it is based on udp protocol and realizes.
Why uboot is Uboot similar to the BIOS bootstrap of pc, is the meaning because universal, i.e., general
Bootstrap, Uboot can guide the CPU of X86, can also guide the CPU of ARM, also have PowerPC's, MIPS etc
CPU。
The invention also discloses a kind of test system of the identical more DUT of IP address, including terminal, tester and multiple DUT,
Terminal is connected with the network interface 0 of tester, and multiple DUT are connected one by one respectively with the network interface 1 of tester to n, as the present invention one
Embodiment, the terminal can be PC.
In the test system of the present invention, further include：
Setting module, for making the IP numbers of network interface 0 of tester be more than or equal to n+1, wherein, n represents DUT quantity, wherein
IP0 is DUT virtual IP addresses for tester IP in itself, IP1 to n, and each IP of network interface 0 corresponds to a DUT respectively；
Change access modules, for assuming that DUT IP be X, the IP of network interface 1 to the n of tester be X+1 to X+
N, the access to DUT IP X is converted to by the access of all IP m to network interface 0, and is tied up data packet and exported by network interface m.
The test system further includes document transmission module, TFTP ports is bound in document transmission module, at the same time
Increase the IP address section Y+N before TFTP states to network interface 1-n.
In the document transmission module, inside is route the IP Y of the access map of TFTP ports to TFTP states.
In the document transmission module, the received ARP messages of network interface 1-n are monitored, are sent if ARP contents are uboot
, then actively send the arp response message that uboot needs.
The present invention realizes single PC, and single tester tests the DUT of multiple identical IP, and network connection topologies are simple, while greatly
Reduce production cost greatly；The invention just reduces the cost of 3 PC in common 4 DUT test environments, simultaneously because only
A computer is needed, operation also becomes simple, improves the efficiency of production line.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
