Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the flow chart of address field distribution method embodiment one of the present invention.Present embodiments provide a kind of address field distribution method, the method can be performed by address field distributing equipment, and this equipment can pass through software and/or hardware implementing.This equipment is specifically as follows BAS Broadband Access Server (Broadband Remote Access Server, be called for short BRAS) in, wherein BRAS generally has multiple, be positioned at the edge of backbone network, access address can be distributed for user, the data access of agreement (Internet Protocol the is called for short IP) net making user can realize interconnecting between the network of bandwidth.The intercommunication of each BRAS, shares to realize each BRAS address field, improves address field utilance.It will be understood by those skilled in the art that in specific implementation process, each BRAS both may be a BRAS, can be again the second BRAS.Namely each BRAS comprises the function of a BRAS and the function of the 2nd BRAS.The present embodiment, elaborates first using a BRAS as executive agent to address field distribution method at this.As shown in Figure 1, the method for the present embodiment can comprise:
Step 101 a: BRAS determines the first subaddressing section needing application from the available address section of the machine.
In specific implementation process, first can in each BRAS configuration address section, wherein, the address field of configuration on each BRAS must exist with the address field that configures on other BRAS and occurs simultaneously, and each BRAS can configure at most 32 sector address sections, and span is 0-31.Especially, each BRAS that address field existence is occured simultaneously constitutes address shared group.
When subscriber equipment accesses one of them BRAS by PPPOE or DHCP mode, for convenience of description, the present embodiment is referred to here as a BRAS, and namely during subscriber equipment access the one BRAS, a BRAS determines the first subaddressing section needing application from the machine available address section.Wherein, the available address section of the machine is the address field being also not yet assigned to user.When the subaddressing section in address field distributes to the user of a BRAS, or this subaddressing section is when being distributed to user by other BRAS, Duan Weiyi subaddressing, the subaddressing section that this is assigned with, need remove this subaddressing section from the machine available address section, obtains new the machine available address section.In specific implementation process, a BRAS can carry out record by subaddressing section to this, obtains record sheet, when again applying for subaddressing section, getting rid of the subaddressing section recorded in this record sheet, from the machine available address section, applying for subaddressing section.
Step 102 a: BRAS sends the first address request to the 2nd BRAS, the first address request carries the first subaddressing section, and the address field of a BRAS and the address field of the 2nd BRAS exist common factor.
Occur simultaneously because the address field of a BRAS and the address field of the 2nd BRAS exist, therefore, after a BRAS determines the first subaddressing section needing to apply for from the available address section of the machine, one BRAS needs to the 2nd BRAS(i.e. other BRAS) send the first address request, wherein, carry this first subaddressing section in first address request, determine to make the 2nd all BRAS whether a BRAS can use this first subaddressing section.Especially, can comprise at most 65535 BRAS in the shared group of address, each BRAS has respective mark, and a BRAS according to the mark of each 2nd BRAS, can send address request to each 2nd BRAS.
Step 103 a: BRAS receives the Address requests response that the 2nd BRAS returns, Address requests response is used to indicate the 2nd BRAS and allows a BRAS to apply for the first subaddressing section.
When the 2nd BRAS allows a BRAS to apply for this first subaddressing section, to a BRAS return address request response, be used to indicate the 2nd BRAS and allow a BRAS to apply for the first subaddressing section.One BRAS receives the Address requests response that the 2nd BRAS returns.
Step 104: after determining that the 2nd BRAS allows a BRAS to apply for the first subaddressing section, a BRAS is from the first Duan Zhongwei user equipment allocation address, subaddressing.
When after the Address requests response that BRAS reception the 2nd BRAS returns, determine that the 2nd BRAS allows a BRAS to apply for the first subaddressing section, a BRAS is from the first Duan Zhongwei user equipment allocation address, subaddressing.Meanwhile, a BRAS removes this first subaddressing section from residue available address section, forms new available address section, when a BRAS applies for subaddressing again, determines the first subaddressing section needing application in the available address section that this is new.
The address field distribution method that the embodiment of the present invention provides, a BRAS determines the first subaddressing section needing application from the available address section of the machine; One BRAS sends the first address request to the 2nd BRAS, and the first address request carries the first subaddressing section, and the address field of a BRAS and the address field of the 2nd BRAS exist common factor; One BRAS receives the Address requests response that the 2nd BRAS returns, and Address requests response is used to indicate the 2nd BRAS and allows a BRAS to apply for the first subaddressing section; After determining that the 2nd BRAS allows a BRAS to apply for the first subaddressing section, one BRAS is from the first Duan Zhongwei user equipment allocation address, subaddressing, the address field that each BRAS mode through consultation achieves each BRAS is shared, improve the utilance of address field, and without the need to carrying out allocation address section by unified network element, solve the problem of distribution bottlenecks.
On the basis of Fig. 1 embodiment, the address field distribution method that the embodiment of the present invention provides also comprises: a BRAS receives the second address request that the 2nd BRAS sends, and the second address request carries the second subaddressing section needing application; Whether the one BRAS is consistent with the second subaddressing section according to the first subaddressing section, determines whether the 2nd BRAS can apply for the second subaddressing section
In specific implementation process, whether a BRAS is consistent with the second subaddressing section according to the first subaddressing section, determines whether the 2nd BRAS can apply for the second subaddressing section.Specifically can be divided into following possible implementation:
A kind of possible implementation is, after a BRAS determines to need application first subaddressing section, when the first subaddressing section is consistent with the second subaddressing section, then a BRAS compares the priority of a BRAS and the priority of the 2nd BRAS.
In specific implementation process, each BRAS in the shared group of address has respective priority, and the span of priority is 0-65535, and priority value is less, and priority is higher.Meanwhile, in the second address request that the 2nd BRAS sends, the priority of the 2nd BRAS can also be comprised.When the first subaddressing section is consistent with the second subaddressing section, the BRAS that priority is high obtains corresponding subaddressing section, and the BRAS that priority is low applies for subaddressing section again.It will be understood by those skilled in the art that in specific implementation process, may occur that a BRAS is identical with the priority that the 2nd BRAS configures.
One BRAS compares the priority of a BRAS and the 2nd BRAS, and determines whether that permission the 2nd BRAS applies for the second subaddressing section according to priority comparative result, specifically can have the situation that three kinds are possible:
A possible situation, when the priority of a BRAS is greater than the priority of the 2nd BRAS, a BRAS refuses the 2nd BRAS and applies for the second subaddressing section.In specific implementation process, a BRAS can send address refusal response to the 2nd BRAS, and to refuse the 2nd BRAS application, a BRAS can not also make any response.
Another kind of possible situation, when priority lower than the 2nd BRAS of the priority of a BRAS, then a BRAS allows the 2nd BRAS to apply for the second subaddressing section.In specific implementation process, a BRAS sends Address requests response to the 2nd BRAS, applies for the second subaddressing section to allow the 2nd BRAS.
Another possible situation, when the priority of a BRAS equals the priority of the 2nd BRAS, compares the IP address of a BRAS and the IP address of the 2nd BRAS; When the result compared do not meet permission the 2nd BRAS apply for the condition of the second subaddressing section time, the one BRAS refuse the 2nd BRAS apply for the second subaddressing section.In specific implementation process, if the IP address value of a BRAS is less than the IP address value of the 2nd BRAS, then a BRAS determines not allow the 2nd BRAS to apply for the second subaddressing section, if the IP address value of a BRAS is greater than the IP address value of the 2nd BRAS, then a BRAS determines that permission the 2nd BRAS applies for the second subaddressing section.
Another kind of possible implementation is, after a BRAS determines to need application first subaddressing section, when the first subaddressing section and the second subaddressing section are not occured simultaneously and the second subaddressing section belongs to the available address section of a BRAS, one BRAS allows the 2nd BRAS to apply for the second subaddressing section, and removes the second subaddressing section from the available address section of a BRAS.
In specific implementation process, one BRAS sends Address requests response to the 2nd BRAS, the second subaddressing section is applied for allow the 2nd BRAS, and the second subaddressing section is removed from residue available address section, form new available address section, when a BRAS applies for the first subaddressing section again, in the available address section that this is new, determine the first subaddressing section needing application.
The address field distribution method that the embodiment of the present invention provides, the second address request of the 2nd BRAS transmission is received by a BRAS, one BRAS determines that whether the second subaddressing section that a BRAS needs the first subaddressing section of application and the 2nd BRAS to need to apply for is consistent, when a BRAS determines that the second subaddressing section needing the first subaddressing section of application and the 2nd BRAS to need to apply for is consistent, then according to priority, a BRAS determines whether that permission the 2nd BRAS applies for the second subaddressing section, not only achieve sharing of the address field of each BRAS, also assures that and only to be used by a BRAS at the same address field of synchronization, this BRAS is carried out in order from Duan Zhongwei user equipment allocation address, subaddressing.
Fig. 2 is the flow chart of address field distribution method embodiment two of the present invention.Present embodiments provide a kind of address field distribution method, the method can be performed by address field distributing equipment, and this equipment can pass through software and/or hardware implementing.This equipment is specifically as follows BAS Broadband Access Server (Broadband Remote Access Server, be called for short BRAS) in, wherein BRAS generally has multiple, be positioned at the edge of backbone network, access address can be distributed for user, the data access of agreement (Internet Protocol the is called for short IP) net making user can realize interconnecting between the network of bandwidth.The intercommunication of each BRAS, shares to realize each BRAS address field, improves address field utilance.It will be understood by those skilled in the art that in specific implementation process, each BRAS both may be a BRAS, can be again the second BRAS.The present embodiment, elaborates using the 2nd BRAS as executive agent to address field distribution method at this.As shown in Figure 2, the method for the present embodiment can comprise:
Step 201, the 2nd BRAS receive the first address request that a BRAS sends, and the first address request carries the first subaddressing section that a BRAS needs application, and the address field of a BRAS and the address field existence of the 2nd BRAS are occured simultaneously;
It will be appreciated by those skilled in the art that, in specific implementation process, 2nd BRAS receives the first address request that an one or more BRAS sends, wherein, first address request carries the first subaddressing section of a BRAS application, and the address field of a BRAS and the address field of the 2nd BRAS exist common factor.Meanwhile, the first subaddressing section can be discontinuous, when the first subaddressing section is multistage, also indicates the hop count order of the first subaddressing section in the first address request.
Step 202, the 2nd BRAS determine that whether the first subaddressing section is the available address section in the address field of the 2nd BRAS;
Address field due to the address field of a BRAS and the 2nd BRAS exists and occurs simultaneously, and therefore, the 2nd BRAS needs to determine that whether the first address field is the available address section in the address field of the 2nd BRAS.When the 2nd BRAS determines that the first subaddressing section is not the available address section in the address field of the 2nd BRAS, then the 2nd BRAS allows a BRAS to apply for this first subaddressing section.When the 2nd BRAS determines that the first subaddressing section is the available address section in the address field of the 2nd BRAS, then carry out step 203.
Step 203, after determining that the first subaddressing section is the available address section in the address field of the 2nd BRAS, to a BRAS return address request response, Address requests response is used to indicate the 2nd BRAS and allows a BRAS to apply for the first subaddressing section.
Particularly, after determining that the first subaddressing section is the available address section in the address field of the 2nd BRAS, the 2nd BRAS responds to a BRAS return address, specifically comprises following process:
2nd BRAS determines that whether the second subaddressing section that the first subaddressing section and the 2nd BRAS need to apply for is consistent;
If not, then the 2nd BRAS is to a BRAS return address request response, particularly, when the first subaddressing section and the second subaddressing section inconsistent time, illustrate that the 2nd BRAS is current and do not use this first subaddressing section, and current also application uses this first subaddressing section, then the 2nd BRAS is to a BRAS return address request response.
If so, the 2nd BRAS compares the priority of a BRAS and the priority of the 2nd BRAS, and each BRAS has respective priority, and the span of priority is 0-65535, and priority value is less, and priority is higher.
When priority higher than the 2nd BRAS of the priority of a BRAS, the 2nd BRAS is to a BRAS return address request response.
When priority lower than the 2nd BRAS of the priority of a BRAS, the 2nd BRAS ignores the first address request that a BRAS sends, and does not namely do any reply, or to a BRAS return address refusal response.
When comparative result be the priority of a BRAS identical with the priority of the 2nd BRAS time, the 2nd BRAS compares the IP address of a BRAS and the IP address of the 2nd BRAS; When the result compared meet permission the one BRAS apply for the condition of the first subaddressing section time, the 2nd BRAS is to a BRAS return address request response.Particularly, IP address is the IP address that BRAS sends address request.If the IP address value of a BRAS is less than the IP address value of the 2nd BRAS, then the 2nd BRAS allows a BRAS application, if the IP address value of a BRAS is greater than the IP address value of the 2nd BRAS, then the 2nd BRAS determines not allow a BRAS application.
Alternatively, when the 2nd BRAS allows a BRAS to apply for the first subaddressing section, the 2nd BRAS removes the first subaddressing section from the available address section of the 2nd BRAS.By which, ensure that the 2nd BRAS is to the management of available address section, can not cause the address conflict of a BRAS and the 2nd BRAS, and when the 2nd BRAS applies for the second subaddressing section again, can not apply for that a BRAS using address field.
The address field distribution method that the embodiment of the present invention provides, the first address request of a BRAS transmission is received by the 2nd BRAS, first address request carries the first subaddressing section that a BRAS needs application, and the address field of a BRAS and the address field of the 2nd BRAS exist common factor; 2nd BRAS determines that whether the first subaddressing section is the available address section in the address field of the 2nd BRAS; After determining that the first subaddressing section is the available subaddressing section in the address field of the 2nd BRAS, to a BRAS return address request response, Address requests response is used to indicate the 2nd BRAS and allows a BRAS to apply for the first subaddressing section, not only achieve sharing of the address field of each BRAS, also assures that and only to be used by a BRAS at the same address field of synchronization, this BRAS is carried out in order from Duan Zhongwei user equipment allocation address, subaddressing.
Fig. 3 is the signaling diagram of address field distribution method embodiment three of the present invention, below in conjunction with Fig. 3, is described in detail to the address field distribution method that the embodiment of the present invention provides.In figure 3, BRAS-A can be understood as BRAS, a BRAS-B and BRAS-C and can be understood as the 2nd BRAS.Below first BRAS-A, BRAS-B and BRAS-C are briefly described.
