In the embodiment of the present invention, describe access device and determine whether the IP address that described terminal equipment uses is static ip address by the IP address and MAC Address judging whether to store in dynamic address binding table described terminal equipment, if, then the IP address of described terminal equipment and MAC Address are stored in described dynamic address binding table, like this, facilitate described access device to obtain the IP address of described terminal equipment and MAC Address, and when described terminal equipment back-call network, access device can by directly getting IP address and the MAC Address of described terminal equipment in dynamic address binding table, the efficiency that access device E-Packets can be improved.Access device simulation generates DHCP message, use standard DHCP message form, change is not made to form, just can by the accessing position information of the user of static configuration IP address write DHCP message, upper layer network equipment (as gateway device) does not need to make any change and configuration, just by obtaining the mode of DHCP message, described DHCP message can be resolved, gets the accessing position information of the user of static configuration IP address easily.For the DHCP message of different-format, concrete generation method is identical, does not repeat herein.
In actual applications, access request comprises the ARP request of terminal equipment initiation or the data message of terminal equipment transmission; Accessing position information comprises the ID of access device, terminal equipment is linked into access device port numbers or SSID; DHCP message comprises DHCP_discover message, DHCP_request message and DHCP_inform message.Be applicable to above-mentioned all embodiments, therefore not to repeat here.
Be switch by access device below, gateway device is that wideband network gateway is (English: broadbandnetworkgateway, be called for short: BNG), terminal equipment is terminal computer, described computer uses static ip address, the IP address of described computer is 1.1.1.1, MAC Address is ZZZZZZ, the described computer port numbers be linked on switch is No. 34 is example, specifically describe when described computer access network, according to implementation procedure of the present invention, please refer to Figure 10, in the embodiment of the present invention, the embodiment of embody rule scene comprises:
Described computer sends access request to described switch.
Described switch receives the access request of computer; Resolve described access request, the IP address obtaining described computer is 1.1.1.1, and MAC Address is ZZZZZZ; The IP-MAC binding table arranged in search switch, determines the IP address and the MAC Address that do not store described computer in described IP-MAC binding table; The IP address 1.1.1.1 of described computer and MAC Address ZZZZZZ is stored in IP-MAC binding table; Get IP address 1.1.1.1, MAC Address ZZZZZZ and No. 34, the incoming end slogan of described computer on described switch of described computer; A new DHCP_discover message is generated by DHCP configuration order; The IP address 1.1.1.1 of described computer is write in the ClientIPaddress field of described DHCPdiscover message, write the MAC Address ZZZZZZ of described computer in ClientMACaddress field, in the option option82 of described DHCPdiscover message, write accessing position information 34; With DHCPdiscover message described in broadcast transmission, receive described DHCPdiscover message to enable gateway device.
The above, above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
