See also Fig. 3, the synoptic diagram of the ICP/IP protocol stack architexture when Fig. 3 is a telechiric device of the present invention as the terminal of WLAN (wireless local area network) or by wired ADSL visit Internet, described ICP/IP protocol stack architexture comprises application layer, transport layer, network layer, data link layer, also comprise media access control sublayer in the described data link layer, application layer comprises http protocol, File Transfer Protocol, SMTP and POP3 agreement, is respectively applied for the function that realizes that Web page browsing, file are downloaded and sent and received e-mail.
Adopt above-mentioned the 1st, 2, when 3 kind of method carried out web access, realize the Internet network access functions by the ICP/IP protocol stack.
Realize that as a terminal access device of WLAN (wireless local area network) the function of Web page browsing is the procedure declaration of example to described telechiric device visit Internet net with described telechiric device below:
Described telechiric device forms one 802.11 WLAN environment by wireless module and described digital equipment (comprising PC), and PC has linked Internet.
The user at first sends a HTTP request by the Web browser in the operating system of described telechiric device, network application-level protocol HTTP adds that with request msg http header is packaged into packet and sends into the transport layer of ICP/IP protocol stack, network layer, and the packet of all upper strata being sent at each layer adds that corresponding header sends into one deck down.Send into wireless module at last, the IP data envelope that wireless module is sent network layer here is dressed up Frame (mac frame) and is sent to the wireless module (wireless NIC) of receiving equipment (PC) by wireless module, the wireless module of PC and ICP/IP protocol stack obtain web page contents by ISP from purpose web server, issue the wireless module of telechiric device then with the form of Frame, after the telechiric device wireless module receives Frame, according to handling with the inverse process that sends the HTTP request, take out at first that data division in the Frame is sent into network layer and transport layer is handled, give application layer protocol HTTP at last and handle web page contents is shown in Web browser.To the application of using the FTP file in download and sending and receiving e-mail, just application layer protocol is realized differently, and the processing procedure of bottom is identical, only need be for operating system add the corresponding client application program, as the ftp client application program etc., can realize.
When adopting above-mentioned the 4th kind of mode to carry out web access, if speed is enough fast, as 3G network, this moment is after connecting local ISP by communication network (3G network), directly insert ordinary Internet by ISP, do not need to connect the WAP gateway server, still realize the Internet network access functions by the ICP/IP protocol stack, the process of visiting Internet with above-mentioned 1,2,3 kind of mode is similar, does not repeat them here.
When above-mentioned the 4th kind of mode carried out web access, because be subjected to the influence of the data transmission rate of current wireless channel, with by wired access and insert Internet as the WLAN terminal mode and compare, usually speed is lower, if network is busy, network speed can be slower, adopt this moment the wap protocol stack to realize getting online without being tethered to a cable, and browse the WAP page by the WAP page browser, because the WAP page (adopting the WML file layout) takies Internet resources still less than the common web page (adopting the Html file layout).
Described telechiric device realizes that by described wap protocol stack the method for getting online without being tethered to a cable is: described telechiric device sends solicited message, connect the local ISP of ISP (Internet Service Provider) by communication network (GSM, CDMA or other mobile network); The local ISP of ISP connects the wireless application protocol (wap) gateway server; The WAP gateway server sends request to the object content server, and the object content server is passed to the WAP gateway server with the information html file; Information WML file after the WAP gateway server will use the wap protocol stack to handle is dealt into the local ISP of ISP (Internet Service Provider), and data message is sent to communication network by the local ISP of ISP, telechiric device receives the Internet data message of sending from communication network by wireless module, thereby can carry out the Web page browsing, operation such as send and receive e-mail.
In the transmission process to network packet, multifunction remote-controller of the present invention adopts " zero-copy " technology to improve the performance of network data transmission.
See also Fig. 4, Fig. 4 is the synoptic diagram of the mode of traditional network data bag, because the network equipment (normally NIC) driver operates in kernel spacing, after the network equipment is received packet, packet can leave in the kernel spacing, because upper layer application operates in user's space, and direct access kernel space, therefore to the packet in the network equipment be copied in the upper layer application system by system call, cause system performance to descend.
See also Fig. 5, multifunction remote-controller of the present invention is realized " zero-copy " technology of network packet by the dma controller in the described control module, obtain the bus control right of processor by described dma controller after, described dma controller is directly carried out read-write operation to storer.
The network packet of at first utilizing dma controller that described wireless module is received is directly delivered in the pre-assigned address space of system kernel, avoids the processor processing of described control module; Simultaneously, the region of memory of storage packet in the system kernel is mapped to the application space of trace routine, trace routine directly conducts interviews to this piece internal memory, thereby reduced the memory copying of system kernel to user's space, improved the expense that real time of data transmission has reduced system call simultaneously, and do not need to take the processor resource of control module, improved the overall performance that described telechiric device carries out network processes.
The above only is a preferred implementation of the present invention; should be understood that; the structure of existing telechiric device need not be described; but; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement and distortion, these improvement and distortion also should be considered as falling into protection scope of the present invention.
