Step 301：LNS address lists are obtained, determines that a LNS is standby each other with the 2nd LNS according to the LNS address lists
Part relation.
LNS address lists can in the following manner be obtained：
One kind is achieved in that：First LNS static configurations obtain LNS address lists.
Another kind is achieved in that：First LNS is from Layer 2 Tunneling Protocol LAC (L2TP Access
Concentrator, abbreviation LAC) LNS address lists are obtained, specifically, a LNS and Layer 2 Tunneling Protocol LAC
LAC is set up in tunneling process, and the address information of LNS is carried by the property value in AVP message, according to the address of the LNS for carrying
Information sets up LNS address lists, it is also possible to after a LNS and Layer 2 Tunneling Protocol LAC LAC set up tunnel, lead to
The address information of the LNS that the property value crossed in AVP message is carried, the address information according to the LNS for carrying sets up LNS address columns
Table, it would however also be possible to employ other modes, is not particularly limited to this application.
Determine that a LNS and the 2nd LNS backup each other relation according to LNS address lists, the LNS ground in LNS address lists
Location information is arranged in sequence, and first LNS in acquiescence LNS lists is the in main LNS, and LNS lists
One LNS and the 2nd LNS backup each other relation, thus the 2nd LNS processes the message that a LNS sends, and other LNS are sent
Message is not processed.
Because a LNS and the 2nd LNS backup each other relation, thus a LNS and the 2nd LNS can share address pool,
First LNS and the 2nd LNS can simultaneously for user distributes address information, it is also possible to which a LNS enters row address distribution, or second
LNS enters row address distribution, a LNS is given tacit consent under normal circumstances and enters row address distribution, when two equipment are simultaneously different user point
During with IP address, a LNS and the 2nd LNS same times may distribute the situation of same IP address, in order to prevent this feelings
Condition occurs, thus when IP address is distributed for user, determines the first address state of the first address, and first address does not exist
Used on 2nd LNS.
Step 302：Determine the first address state of first address.
The first address state of the first address can in the following manner be determined：
First LNS sends the first message to the 2nd LNS, wherein, first message carries the first address.
The form that first message may be referred to charging message is transmitted, i.e. source address information, mesh are carried in the first message
Address information and the first address etc..
The first feedback message of the 2nd LNS transmissions is obtained, the first ground of the first address is carried in the first feedback message
Location state.
First LNS to the 2nd LNS send the first message, wherein, the first message carry the first address, make the 2nd LNS according to
The LNS address pools of first address search the 2nd, determine first address state of first address in the 2nd LNS address pools, by what is determined
First address state is carried and sent to a LNS in the first feedback message.
First LNS obtains the first address state of the first address according to the first feedback message.
If the first address state is unallocated state, user is distributed into the first address, if the first address state is for
Distribution state, then reselect next address, re-executes step 302.
The application implementation method, first, a LNS selected the first address before address is distributed, and determined the first address
First address state, if the first address state is unallocated state, distributes to user, without to address by first address
Pond is divided, and alleviates the complexity to address pool planning, while reserved need not also distribute address, and then solves user point
With the problem that address wastes.
A relation secondly as LNS and the 2nd LNS backup each other a, it is achieved thereby that LNS and the 2nd LNS is shared
Address pool, and need not be that each LNS needs to be needed to divide different address pools according to user, solve user's distribution address and waste
Problem.

First LNS sends second and feeds back message to the 2nd LNS, can be used with the second address for informing the 2nd LNS, explanation
First LNS does not use the address information, and locks the second address.
First LNS locks the second address, while the 2nd LNS is also required to lock the second address, so when a LNS failures
When, when the 2nd LNS enters row address distribution, do not result in the problem of address conflict.
First LNS locks the second address, and now the second address cannot again participate in the distribution of address；First LNS unlocks
Or when the tunnel teardown between LAC and LNS, can release to two address locking.
It is described when there are two or more LAC between client and LNS as a kind of implementation method therein
2nd LNS can be used as described two or two or more LAC main LNS.
During in order to prevent the 2nd LNS as main LNS, tunnel is individually set up with LAC and address generation address conflict is distributed
Problem, can first determine whether whether the 2nd LNS has LNS address lists, if so, then the 2nd LNS can be from larger available address
Start to distribute address, for example：Address pool range is 10.0.0.1~10.0.0.100, then the 2nd LNS can be from 10.0.0.100
Start to obtain distribution address, can as far as possible avoid address from distributing and produce conflict.Certain 2nd LNS can also from it is less can land used
Location starts to obtain distribution address.The method of distribution address is obtained, conflict is produced as long as can reach and avoid address to distribute as far as possible,
Method to this application not to specific distribution address is limited.
The application implementation method, first, a LNS selected the first address before address is distributed, and determined the first address
First address state, if the first address state is unallocated state, distributes to user, without to address by first address
Pond is divided, and alleviates the complexity to address pool planning, while reserved need not also distribute address, and then solves user point
With the problem that address wastes.
