Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are done concrete description:
Please refer to shown in Figure 2ly, it is a configuration diagram of the present invention.The present invention includes: DynamicHost is set communication protocol server 210 (Dynamic Host Configuration Protocol server), at least one client 220 and many simple and easy file transfer protocol servers 230 (tftp server).Each client 220 links Dynamic Host Configuration Protocol server 210 and tftp server 230 through Internet (internet), corporate intranet (intranet) or local-area network (Lan).
That tftp server 230 is adopted is simple and easy file transfer protocol (TFTP), and this is a kind of simple agreement that is used for transmitting archives, operate in UDP (User Datagram Protocol, UDP) on.Being designed to little of simple and easy file transfer protocol and simply be easy to operation, therefore, simple and easy file transfer protocol lacks FTP (File Transfer Protocol, many characteristics FTP).
(Application Programming Interface, API), interface routine 240 is in order to the networking package of interception from client 220 for storage interface program in the Dynamic Host Configuration Protocol server 210.When client 220 was activated, client 220 at first can be sent a broadcasting packages, required address, a dynamic networking (Internet Protocol address).Dynamic Host Configuration Protocol server 210 can provide an address, operational networking and subnet road shielding (subnet mask) to client 220 according to configured address at present.After client 220 was confirmed the address, networking of self, Dynamic Host Configuration Protocol server 210 will send other configuration information, in configuration information, has also comprised the address, networking of tftp server 230.
Therefore when 220 pairs of Dynamic Host Configuration Protocol server 210 of client required the address, networking of self, Dynamic Host Configuration Protocol server 210 of the present invention was handled according to following step accordingly, please refer to shown in Figure 3:
Step S310: runnable interface program in Dynamic Host Configuration Protocol server, in order to intercept and capture the configuration information that Dynamic Host Configuration Protocol server sends to client;
Step S320: interface routine is revised the address information of the tftp server in the configuration information, and returns connection request according to amended configuration information and give client; And
