In the present embodiment, the state of the first local protection group comprises the state of a BRAS and the state of the 2nd BRAS.Need to prove that the 2nd BRAS can be provided with a timer, thus can be in the scheduled time, for example: about 10s, send the state of the first local protection group to a BRAS.Concrete, the 2nd BRAS sends to a BRAS by CR with the state of the first local protection group.
It should be noted that in the various embodiments of the present invention and the scheduled time is not limited, and those skilled in the art can be provided with the scheduled time arbitrarily according to the actual conditions needs.
When the state of step 102, BRAS BRAS in the state of judging the first local protection group and the state of the 2nd BRAS all are main state; then according to the logging request of first terminal that receives; the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection.
In the present embodiment, first terminal can be specially apparatus such as computer; Registered permanent residence information comprises local registered permanent residence information or far-end registered permanent residence information, and wherein, local registered permanent residence information is used to represent terminal from this wire over ground, and far-end registered permanent residence information is used to represent to back up the registered permanent residence information of coming from opposite end BRAS.In the present embodiment, the registered permanent residence information that BRAS only judges the terminal correspondence is local registered permanent residence information, during promptly from this wire over ground, just can carry out heartbeat detection to this terminal.For example, this registered permanent residence information can be " 0 " or " 1 " of Digital Logic, and wherein, " 0 " is used to represent that registered permanent residence information is local registered permanent residence information; " 1 " is used to represent that registered permanent residence information is far-end registered permanent residence information.In addition, this registered permanent residence information can be stored among the BRAS in this terminal corresponding terminal information form.
In addition, when first convergence switch that links to each other with a BRAS and with second convergence switch that the 2nd BRAS links to each other between following time of physical link normal condition, the state of a BRAS is a stand-by state, the state of the 2nd BRAS is main state; When the physical link between first convergence switch and second convergence switch breaks down, the state of the 2nd BRAS and a BRAS all is main state, two main phenomenons promptly appear, when first terminal that dials again after first terminal that then belongs to first convergence switch goes offline or belong to first convergence switch dials for the first time, the logging request that the one BRAS sends according to this first terminal that receives, the registered permanent residence information that writes down first terminal is local registered permanent residence information, thereby can carry out heartbeat detection to first terminal.It should be noted that when a BRAS does not detect the heartbeat of first terminal,, and stop this charging then to the processing of rolling off the production line of first terminal.
In the present embodiment, a BRAS can also be with the registered permanent residence information of first terminal, and promptly local registered permanent residence information is carried in the first back-up terminals information, sends to the 2nd BRAS.Wherein this first back-up terminals information comprises internet (the Internet Protocol of first terminal; Be called for short: IP) other information such as address; After the 2nd BRAS receives this first back-up terminals information, the local registered permanent residence information of first terminal in the first back-up terminals information is recorded as far-end registered permanent residence information.
In the present embodiment, when the state of the 2nd BRAS and a BRAS all is main state, the 2nd BRAS is a far-end registered permanent residence information according to the registered permanent residence information of record first terminal, can not carry out heartbeat detection to first terminal, can be because of the heartbeat that does not detect first terminal yet to the processing of rolling off the production line of first terminal; Simultaneously, the one BRAS is local registered permanent residence information according to the registered permanent residence information of record first terminal, this first terminal is carried out heartbeat detection, and can be when not detecting the heartbeat of first terminal, to the processing of rolling off the production line of first terminal, thereby realized that when the state of the 2nd BRAS and a BRAS all is main state this first terminal dials and reaches the standard grade after the success, not the phenomenon that can occur going offline.
In the present embodiment, receive the state of the first local protection group of the 2nd BRAS transmission by a BRAS, and when the state of the state of a BRAS and the 2nd BRAS all is main state in the state of judging this first local protection group, the logging request that sends according to first terminal that receives then, the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection; The registered permanent residence information that first terminal is sent is carried in the first back-up terminals information and sends to the 2nd BRAS simultaneously, for the 2nd BRAS the local registered permanent residence information of first terminal is recorded as far-end registered permanent residence information.Therefore, under two masters' situation, BRAS only carries out heartbeat detection to the terminal that is recorded as local registered permanent residence information correspondence, simultaneously, the terminal that is recorded as far-end registered permanent residence information is not carried out heartbeat detection, reach the standard grade or roll off the production line thereby make terminal only control it by a BRAS, thereby when having realized in dual-machine hot backup system occurring two main phenomenon, terminal dialing is reached the standard grade and can not gone offline after the success, can continue online to guarantee terminal.
The flow chart of another embodiment of the processing method that Fig. 4 goes offline for terminal of the present invention, as shown in Figure 4, the method for present embodiment comprises:
In the present embodiment, as shown in Figure 1, under the physical link normal condition between first convergence switch and second convergence switch, the state of a BRAS is a stand-by state, and the state of the 2nd BRAS is main state.The 2nd BRAS receives the logging request that first terminal and second terminal send, and writes down the registered permanent residence information of first terminal and the registered permanent residence information of second terminal is local registered permanent residence information, and first terminal and second terminal are carried out heartbeat detection.Simultaneously, the 2nd BRAS is carried at the registered permanent residence information of first terminal in the 3rd back-up terminals information, and the registered permanent residence information of second terminal is carried in the 4th back-up terminals information, again the 3rd back-up terminals information and the 4th back-up terminals information are sent to a BRAS.Wherein, the 3rd back-up terminals information can comprise other information such as IP address of first terminal, and the 4th back-up terminals information can comprise other information such as IP address of second terminal.
Step 202, a BRAS are recorded as far-end registered permanent residence information with the local registered permanent residence information of first terminal and second terminal respectively.
In the present embodiment, the one BRAS receives the 3rd back-up terminals information and the 4th back-up terminals information, and the local registered permanent residence information of first terminal in the 3rd back-up terminals information is recorded as far-end registered permanent residence information, and the local registered permanent residence information of second terminal in the 4th back-up terminals information is recorded as far-end registered permanent residence information.Need to prove that a BRAS can be with first terminal of record and the local registered permanent residence information stores of second terminal in database.
In addition, because the registered permanent residence information of first terminal that writes down among the BRAS and the registered permanent residence information of second terminal are far-end registered permanent residence information, therefore, a BRAS does not detect first terminal and second terminal, thereby a BRAS does not reach the standard grade to first terminal and second terminal and handles or the processing of rolling off the production line.
In the present embodiment, when the physical link between first convergence switch and second convergence switch broke down, the 2nd BRAS found to detect first terminal, then to the processing of rolling off the production line of first terminal, and stopped charging to first terminal.Simultaneously, the 2nd BRAS deletion is stored in the 3rd back-up terminals information among the 2nd BRAS, and sends first terminal message that rolls off the production line to a BRAS.
In the present embodiment, a BRAS receives the message that rolls off the production line of first terminal of the 2nd BRAS transmission, the then three back-up terminals information of deletion record in a BRAS.At this moment, because the physical link between first convergence switch and second convergence switch breaks down, therefore, the state of a BRAS becomes major state by stand-by state.Promptly the state of a BRAS and the 2nd BRAS all is main state, promptly two main phenomenons.It should be noted that in each embodiment of the present invention when the state of a BRAS and the 2nd BRAS all was main state, BRAS only carried out heartbeat detection to the terminal of minute book landholder message breath, the terminal of record far-end registered permanent residence information is not carried out heartbeat detection.Therefore, when the 2nd BRAS has deleted the local registered permanent residence information of the 3rd back-up terminals information and first terminal, the 2nd BRAS can not carry out heartbeat detection to first terminal, simultaneously, when the 2nd BRAS is local registered permanent residence information in the registered permanent residence information according to record second terminal, can also be to the heartbeat detection of carrying out of second terminal.In addition, when a BRAS was far-end registered permanent residence information in the registered permanent residence information according to second terminal that writes down, a BRAS can not carry out heartbeat detection to second terminal.
In sum, second terminal is just come its reach the standard grade processing or the processing of rolling off the production line by the 2nd BRAS, when the physical link between first convergence switch and second convergence switch broke down, second terminal can also continue online, and the situation that can not occur going offline.
In the present embodiment, the implementation of step 205 and the implementation of step 101 shown in Figure 2 are similar, do not repeat them here.
When the state of step 206, BRAS BRAS in the state of judging the first local protection group and the state of the 2nd BRAS all are main state; the logging request that sends according to first terminal that receives then; the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection.
In the present embodiment, the implementation of step 206 and the implementation of step 102 shown in Figure 2 are similar, do not repeat them here.Need to prove, a BRAS and two BRAS when all being main state of the one BRAS in the state of judging the first local protection group, in order to prevent it is of short duration two main illusion and cause meaningless processing, the 2nd BRAS can postpone the regular hour and send the state of the first local protection group to a BRAS, when a BRAS receives the state of the first local protection group that the 2nd BRAS sends, logging request according to first terminal transmission that receives, the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection; Perhaps a BRAS is at the double state that receives the first local protection group of the 2nd BRAS transmission; and when detecting a BRAS and the 2nd BRAS and all being main state; the logging request that the one BRAS sends according to first terminal that receives; the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection.
In the present embodiment, the implementation of step 207 and the implementation of step 103 shown in Figure 2 are similar, do not repeat them here.Need to prove that when first terminal dials when reaching the standard grade again, a BRAS has received the logging request that this first terminal sends, and the registered permanent residence information that writes down first terminal is local registered permanent residence information, comes first terminal is carried out heartbeat detection.Simultaneously, the registered permanent residence information of first terminal is carried in the first back-up terminals information sends to the 2nd BRAS, so that the 2nd BRAS is recorded as far-end registered permanent residence information with the local registered permanent residence information of first terminal in the first back-up terminals information, thereby make the 2nd BRAS not detect first terminal, promptly in two main phenomenons, dialing first terminal of reaching the standard grade is only made a strategic decision by a BRAS again, and it is reached the standard grade or rolls off the production line.
In the present embodiment, by when two main phenomenon not occurring, only there is the 2nd BRAS that first terminal and second terminal are carried out heartbeat detection, when two main phenomenon occurring, and when the 2nd BRAS does not detect the heartbeat of first terminal, then the 2nd BRAS deletes the end message of first terminal, and sends first terminal and roll off the production line message to a BRAS, so that a BRAS deletes the second back-up terminals information.Simultaneously, make the BRAS that wins receive the state of the first local protection group of the 2nd BRAS transmission, and when the state of the state of a BRAS and the 2nd BRAS all is main state in the state information of judging this first local protection group, the logging request that sends according to first terminal that receives then, the registered permanent residence information that writes down first terminal is local registered permanent residence information, and first terminal is carried out heartbeat detection; The registered permanent residence information that first terminal is sent is carried in the first back-up terminals information and sends to the 2nd BRAS simultaneously, for the 2nd BRAS the local registered permanent residence information of first terminal is recorded as far-end registered permanent residence information.Therefore, under two masters' situation, the one BRAS only carries out heartbeat detection to first terminal that is recorded as local registered permanent residence information correspondence, simultaneously, the 2nd BRAS only carries out heartbeat detection to second terminal that is recorded as local registered permanent residence information, thereby making the BRAS that wins control first terminal reaches the standard grade or rolls off the production line, the 2nd BRAS controls second terminal and reaches the standard grade or roll off the production line, thereby when having realized in dual-machine hot backup system occurring two main phenomenon, terminal dialing is reached the standard grade and can not gone offline after the success, can continue online to guarantee terminal.
Need to prove also that further in another embodiment of the present invention, this method can also comprise:
The one BRAS receives the second back-up terminals information that the 2nd BRAS sends, and the second terminal registered permanent residence information in this second back-up terminals information is local registered permanent residence information;
The one BRAS is recorded as far-end registered permanent residence information with the local registered permanent residence information of second terminal.
In the present embodiment, physical link between first convergence switch and second convergence switch breaks down, and the state of a BRAS and the 2nd BRAS all is main state, second terminal of angelica second convergence switch dials when reaching the standard grade for the first time, the registered permanent residence information that the 2nd BRAS writes down second terminal is local registered permanent residence information, come second terminal is kept heartbeat detection, and make a strategic decision that it is reached the standard grade or rolls off the production line; Simultaneously, the registered permanent residence information of second terminal is carried in the second back-up terminals information sends to a BRAS, the one BRAS receives this second back-up terminals information, and the local registered permanent residence information of second terminal in the second back-up terminals information is recorded as far-end registered permanent residence information, then this second terminal is not detected, thereby it is reached the standard grade or rolls off the production line to have realized second terminal having only the 2nd BRAS to make a strategic decision, and then when having realized in dual-machine hot backup system occurring two main phenomenon, second terminal dialing is reached the standard grade after the success, not the phenomenon that can occur going offline.
Need to prove, for second terminal that belongs to second convergence switch, physical link between first convergence switch and second convergence switch breaks down, and when second terminal sends logging request, the registered permanent residence information that the 2nd BRAS writes down second terminal is local registered permanent residence information, comes the processing of reaching the standard grade or roll off the production line of second terminal; Physical link normal condition between first convergence switch and second convergence switch, and when second terminal sends logging request, the registered permanent residence information that the BRAS that is main state by state writes down second terminal is local registered permanent residence information, and to the processing of reaching the standard grade or roll off the production line of second terminal.
The flow chart of another embodiment of the processing method that Fig. 5 goes offline for terminal of the present invention, as shown in Figure 5, the method for present embodiment comprises:
