Embodiment
For problems of the prior art, embodiments provide a kind of method of address assignment, take Fig. 1 as the application scenarios schematic diagram of the embodiment of the present invention, the method is applied in the network comprising BRAS, terminal equipment and aaa server.In the embodiment of the present invention, BRAS have recorded virtual Domain, and have recorded the corresponding relation between this virtual Domain and one or more true territory.Wherein, the territory of true territory and necessary being of the prior art, and BRAS external (as to aaa server) only can present virtual Domain, one or more true territory can be had under this virtual Domain, and each true territory under this virtual Domain is relatively independent.In the embodiment of the present invention, attribute information corresponding to true territory can configure or inherits from the virtual Domain corresponding with this true territory according to demand.Further, the attribute information that true territory is corresponding specifically includes but not limited to: IP address pool, precedence information and/or bandwidth information.
In the embodiment of the present invention, the attribute information in the multiple true territory that virtual Domain is corresponding can be identical or different.Concrete, the IP address pool in different true territory can be different, and such as, the IP address pool in the true territory 1 that virtual Domain is corresponding is IP address pool 1, and the IP address pool in the true territory 2 that virtual Domain is corresponding is IP address pool 2.The precedence information in different true territory can be identical, also can be different, and such as, the precedence information in the true territory 1 that virtual Domain is corresponding is priority 1, and the precedence information in the true territory 2 that virtual Domain is corresponding is priority 2, and priority 1 will be better than priority 2.The bandwidth information in different true territory can be identical, also can be different, and such as, the bandwidth information in the true territory 1 that virtual Domain is corresponding is 2M, and the bandwidth information in the true territory 2 that virtual Domain is corresponding is 1M.
In the embodiment of the present invention, to the operation in any one true territory corresponding to virtual Domain, all can not have influence on other true territory that this virtual Domain is corresponding.Such as, when revising the IP address pool in true territory 1 corresponding to virtual Domain or precedence information or bandwidth information, all can not have influence on the IP address pool in true territory 2 corresponding to virtual Domain or precedence information or bandwidth information.
In the embodiment of the present invention, the IP address pool in different true territory can be continuous print IP address pool, also can be discrete IP address pool.Such as, the IP address pool 1 in the true territory 1 that virtual Domain is corresponding can be continuous print IP address pool with the IP address pool 2 in true territory 2, also can be discrete IP address pool.
In the embodiment of the present invention, in virtual Domain, can attribute information be comprised, when the true territory that virtual Domain is corresponding does not configure this attribute information, the attribute information of virtual Domain can be inherited.Based on this, can the attribute information in multiple true territory under batch modification virtual Domain.Such as, in virtual Domain, can bandwidth information be comprised, when true territory 1 corresponding to virtual Domain and true territory 2 all do not have configured bandwidth information, then can inherit the bandwidth information of virtual Domain, thus make true territory 1 and true territory 2 inherit the bandwidth information of virtual Domain.
Based on above-mentioned application scenarios, as shown in Figure 2, the method for this address assignment comprises the following steps:
Step 201, BRAS, when receiving the application IP addresses message from terminal equipment, determines the virtual Domain that this terminal equipment is corresponding, and selects a true territory from true territory corresponding to this virtual Domain.
In the embodiment of the present invention, BRAS determines the process of the virtual Domain that terminal equipment is corresponding, specifically include but not limited to as under type: BRAS is when receiving the application IP addresses message from terminal equipment, this application IP addresses message is sent to aaa server, by aaa server utilize the user profile determination terminal equipment that carries in application IP addresses message by Certificate Authority after, virtual Domain corresponding for this terminal equipment is informed to BRAS; Wherein, aaa server have recorded the corresponding relation between virtual Domain and terminal equipment.Further, BRAS receives from virtual Domain corresponding to the terminal equipment of aaa server.
Wherein, terminal equipment is in the process of application IP address, application IP addresses message can be sent (as DHCP (Dynamic Host Configuration Protocol to BRAS, DHCP) request message), in this application IP addresses message, carry the user profile such as username and password corresponding to this terminal equipment.BRAS receives the application IP addresses message from terminal equipment, and this application IP addresses message is sent to aaa server.Aaa server utilizes the user profile such as the username and password carried in this application IP addresses message to judge whether terminal equipment passes through Certificate Authority; If not by Certificate Authority, then aaa server notice BRAS refuses terminal equipment access network, and this process does not repeat them here.
In the embodiment of the present invention, aaa server can record the corresponding relation between virtual Domain and terminal equipment, based on the corresponding relation between this virtual Domain and terminal equipment, when terminal equipment is by Certificate Authority, then aaa server can inquire about the corresponding relation between terminal equipment and virtual Domain that this aaa server records, thus obtain virtual Domain corresponding to this terminal equipment with, and virtual Domain corresponding for this terminal equipment is informed to BRAS, received from virtual Domain corresponding to the terminal equipment of aaa server by BRAS.
In above process, aaa server can record the information of terminal equipment and the corresponding relation of virtual Domain, for aaa server, only the information of storage terminal equipment and the corresponding relation of virtual Domain need be used, what do not need perception self to store is the information of terminal equipment and the corresponding relation of virtual Domain, or the information of terminal equipment and the corresponding relation in true territory, namely aaa server does not need the situation in perception virtual Domain and true territory, concerning aaa server, virtual Domain is consistent with the process in true territory.
In the embodiment of the present invention, BRAS selects the process in a true territory from true territory corresponding to virtual Domain, specifically include but not limited to as under type: when attribute information corresponding to real domain of taking seriously comprises precedence information, BRAS selects precedence information optimum true territory from true territory corresponding to virtual Domain; Or,
When attribute information corresponding to real domain of taking seriously comprises bandwidth information, when the terminal equipment quantity of current access is less than the first numerical value, then BRAS selects bandwidth information maximization true territory from true territory corresponding to virtual Domain; Or, when the terminal equipment quantity of current access is greater than second value, then a BRAS true territory selecting bandwidth information minimum from true territory corresponding to virtual Domain; Wherein, this second value is greater than this first numerical value.
Wherein, by configuring different precedence informations for different true territories, and select precedence information optimum true territory from true territory corresponding to virtual Domain, thus the IP address pool that the true territory that can ensure to be preferably terminal equipment configuration high priority message is corresponding.Such as, when the precedence information of real domain 1 of taking seriously is better than the precedence information in true territory 2, when then having available IP address in the IP address pool 1 in true territory 1, BRAS can select the true territory 1 of precedence information optimum from true territory corresponding to virtual Domain, until when there is no available IP address in the IP address pool 1 in true territory 1, BRAS just can select the true territory 2 of precedence information optimum (now from true territory corresponding to virtual Domain, IP address pool 1 due to true territory 1 has not had available IP address, therefore, BRAS can not select IP address in the IP address pool 1 from true territory 1, namely BRAS can not consider the precedence information in true territory 1, precedence information optimum be true territory 2), thus the IP address that guarantee is preferably in terminal equipment configuration IP address pool 1.
Wherein, according to the time order and function relation of terminal equipment access, BRAS can distribute different bandwidth information for different terminal equipments.Concrete, when the terminal equipment quantity of current access is less than the first numerical value, terminal equipment number ratio is less, and the bandwidth that each terminal equipment distributes can be relatively a little bigger, therefore, BRAS can select bandwidth information maximization true territory from true territory corresponding to virtual Domain.Due to the restriction of total bandwidth, along with the continuous increase of terminal equipment quantity, when the terminal equipment quantity of current access is greater than second value, terminal equipment number ratio is more, the bandwidth that each terminal equipment distributes can point relatively, therefore, a BRAS true territory can bandwidth information being selected minimum from true territory corresponding to virtual Domain.
In the embodiment of the present invention, BRAS selects the process in a true territory from true territory corresponding to virtual Domain, specifically include but not limited to as under type: when all there is no available IP address in the IP address pool that each true territory (i.e. all true territories) that virtual Domain is corresponding is corresponding, then BRAS is that virtual Domain configures new true territory, and comprises not by the IP address pool used in this new true territory.Further, BRAS selects new true territory from true territory corresponding to virtual Domain, namely selects the current true territory reconfigured.
In the embodiment of the present invention, if the negligible amounts of terminal equipment, when in the IP address pool that the true territory that virtual Domain is corresponding is corresponding also not by use IP address time, BRAS deletes this true territory from virtual Domain.
In sum, in the embodiment of the present invention, if the quantity of terminal equipment is more, when all there is no available IP address in the IP address pool that all true territories are corresponding, under virtual Domain, a new true territory can be added again.If the negligible amounts of terminal equipment, in the IP address pool having true territory corresponding also not by use IP address time, this true territory can be deleted under virtual Domain, not affect other the true territory under virtual Domain.
Step 202, BRAS determines the IP address pool that the true territory of current selection is corresponding, and from this IP address pool, selects one not by the IP address used, and by this IP address assignment to terminal equipment.
Such as, if the true territory of current selection is true territory 1, then BRAS determines that the IP address pool of true territory 1 correspondence of current selection is IP address pool 1, and from this IP address pool 1, selects one not by the IP address used, and by this IP address assignment to terminal equipment.Wherein, select one in BRAS secondary IP address pond 1 not by the process of IP address that uses, BRAS directly can utilize the IP address pool 1 of local configuration, selects one not by the IP address used in secondary IP address pond 1; Or, the application IP addresses message of terminal equipment is sent to Dynamic Host Configuration Protocol server by BRAS, the IP address pool 1 of local configuration is utilized by Dynamic Host Configuration Protocol server, one is selected not by the IP address used in secondary IP address pond 1, and this selection do not informed to BRAS by the IP address used, BRAS obtains not by the IP address used.
Based on technique scheme, in the embodiment of the present invention, by safeguarding the corresponding relation between virtual Domain and one or more true territory at BRAS, thus the quantity of the IP address that can use can be expanded.If the quantity of terminal equipment is a lot, the equal corresponding same virtual Domain of a large amount of terminal equipments, and there is no available IP address in IP address pool corresponding to true territory corresponding to this virtual Domain, then can configure new true territory for this virtual Domain, thus can in any configuration do not revised on aaa server and under not affecting the current user's prerequisite used, IP address in the IP address pool that the true territory utilizing this new is corresponding is terminal equipment distributing IP address, avoids terminal equipment cannot be assigned to IP address.Under aforesaid way only needs the virtual Domain on BRAS, add the problem that true territory just can solve address dilatation, do not need to revise any configuration on aaa server, reduce in whole networking because of risk that configuration modification brings.
Based on the inventive concept same with said method, a kind of BRAS is additionally provided in the embodiment of the present invention, be applied in the network comprising BRAS and terminal equipment, described BRAS have recorded virtual Domain, and the corresponding relation that have recorded between described virtual Domain and one or more true territory, as shown in Figure 3, described BRAS specifically comprises:
