Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

It should be noted that, the embodiment of the present invention can be applied in network as shown in Figure 9.Network based on as shown in Figure 9, long-range BAS Broadband Access Server (Broadband Remote Access Server, BRAS) can, by sending AAA message to primary radius server or standby radius server, make primary radius server or standby radius server process user's AAA business.

In prior art, if primary radius server fault, but surpass fault time after Preset Time, BRAS thinks that primary radius server is normal, immediately by user's authentication, mandate and call charge service switch to primary radius server, and primary radius server may be also in malfunction, may cause a large amount of AAA business normal process not compare, in embodiments of the present invention, in the process that BRAS can switch to primary radius server by AAA business by standby radius server at BRAS, according to the first default percentage, send AAA message to primary radius server, the authentication success rate of primary radius server is determined in the AAA response then receiving in first scheduled time according to BRAS, and in the authentication success rate of primary radius server when being preset to power threshold, just determine the in running order normal condition of primary radius server, and all AAA messages of BRAS are sent to described primary radius server, the AAA business that is about to user switches to primary radius server.

Pass through this programme, can reduce because arrive in default fault time, and primary radius server is still in the situation of fault, BRAS blindly switches to primary radius server by user's AAA business, causes the possibility that a large amount of AAA business can not normal process.In this programme, in the process that AAA business is switched to primary radius server by standby radius server, only according to the first default percentage, send an AAA message to primary radius server, and definite primary RIDIUS in Preset Time to the ratio of an AAA message response during higher than predetermined threshold value, just determine that primary radius server is in normal condition, then just user's AAA business is switched to primary radius server, thereby the possibility of the AAA message that the primary radius server that can reduce BRAS in prior art directly user's AAA business to be switched to primary radius server when arrive in default switching time and cause is cannot normal process a large amount of.

Embodiment 1

The embodiment of the present invention provides a kind of message transmitting method, can be applied in process that BRAS switches to primary radius server by AAA business by standby radius server, and as shown in Figure 1, this message transmitting method, comprising:

S101, BRAS send an AAA message to described primary radius server according to the first default percentage.

It should be noted that, user's authentication，authorization，accounting AAA generally adopts radius protocol, and radius protocol is a kind of agreement of C/S structure, at RFC2865, in RFC2866, defines, and protocol contents is simply clear and definite, and expandability is better.

Wherein, because radius protocol is simply clear and definite, expandability is better, and therefore application is comparatively extensive.For example, the passable range of application of radius protocol can comprise in the business such as plain old telephone online, ADSL online, partial wideband online, IP phone, the Virtual Private Dialup Network based on dial user (Virtual Private Dialup Networks, VPDN), mobile phone pre-payment.IEEE has proposed 802.1x standard, and this is a kind of standard based on port, for the access authentication to wireless network, also adopts radius protocol when authenticating.

It should be noted that, while communicating between BRAS and radius server in embodiments of the present invention, the application layer communication protocol adopting is radius protocol.

Exemplary, radius server (primary radius server and standby radius server) can be by setting up a customer data base that stores user name and user cipher, and after receiving AAA message, by user name and the user cipher of storing in customer data base, the AAA business of the corresponding subscriber equipment of described AAA message is carried out to authentication，authorization，accounting, then the configuration information after return authentication is to BRAS, to indicate BRAS:RADIUS server to complete corresponding authentication，authorization，accounting flow process.

S102, BRAS receive the AAA response from primary radius server, and according to the AAA response receiving in first scheduled time, determine the authentication success rate of primary radius server.

Wherein, authentication success rate is for characterizing the disposal ability of primary radius server to a described AAA message, and an AAA response is the response message of primary radius server to an AAA message.

Exemplary, BRAS can start to send an AAA message according to the first default percentage from this BRAS, and extremely the moment of primary radius server starts timing, and statistics moment of starting timing from BRAS play the number of the AAA response that BRAS during this period of time that timing time surpassed for first scheduled time receives, then calculate BRAS and at BRAS, be sent to shared percentage in the sum of an AAA message of primary radius server in the number of a received AAA response of above-mentioned time period, and the authentication success rate using the percentage calculating as primary radius server.

If the authentication success rate of the primary radius server of S103 is more than or equal to, be preset to power threshold, BRAS determines that primary radius server is in normal condition, and all AAA messages that send BRAS are to primary radius server.

Further alternative, the method for the embodiment of the present invention can also comprise: if the described authentication success rate of described primary radius server is preset to power threshold described in being less than, BRAS can determine that described primary radius server is in malfunction.

Further, when the described authentication success rate due to radius server is preset to power threshold described in being less than, BRAS determines that primary radius server is when malfunction, BRAS can continue to carry out: according to the first default percentage, send AAA message to primary radius server, then according to the AAA response receiving in first scheduled time, determine the authentication success rate of primary radius server, and then in authentication success rate higher than being preset to after power threshold, determine that primary radius server is in normal condition, and all AAA messages that send BRAS are to primary radius server.

Or, when the described authentication success rate due to radius server is lower than the described power threshold that is preset to, BRAS determines that primary radius server is when malfunction, and BRAS can directly send all described AAA message of described BRAS to standby radius server.

It should be noted that, the first default percentage can be less than or equal to 1 in the present embodiment.

Wherein, when the first default percentage is less than 1, the method for the embodiment of the present invention can also comprise: BRAS sends the 2nd AAA message to standby radius server according to the second default percentage.Now, the first default percentage and the second default percentage sum are 1.

The message transmitting method that the embodiment of the present invention provides, will recognize in the process that AAA business switches to primary radius server by standby radius server at BRAS, and BRAS sends an AAA message to primary radius server according to the first default percentage; Reception responds from an AAA of primary radius server, and according to the AAA response receiving in first scheduled time, determines the authentication success rate of primary radius server; If the authentication success rate of primary radius server is more than or equal to, be preset to power threshold, determine that primary radius server is in normal condition, and all AAA messages that send BRAS be to primary radius server.

Pass through this programme, can reduce because arrive in default fault time, and primary radius server is still in the situation of fault, BRAS blindly switches to primary radius server by user's AAA business, causes the possibility that a large amount of AAA business can not normal process.

Concrete, in a kind of application scenarios of the present embodiment, the first default percentage is less than 1.Now, in the process that AAA business is switched to primary radius server by standby radius server at BRAS, only a part of AAA message is issued to primary radius server (sending an AAA message to primary radius server according to the first default percentage), and definite primary RIDIUS in Preset Time to the ratio of this part of AAA message response during higher than predetermined threshold value, just determine that primary radius server is in normal condition, then just user's AAA business is switched to primary radius server, thereby the possibility of the AAA message that the primary radius server that can reduce BRAS in prior art directly user's AAA business to be switched to primary radius server when arrive in default switching time and cause is cannot normal process a large amount of.

In the another kind of application scenarios of the present embodiment, the first default percentage equals 1.Now, in the process that AAA business is switched to primary radius server by standby radius server at BRAS, with similar in prior art, all AAA messages are issued to primary radius server (sending an AAA message to primary radius server according to the first default percentage), but can be in determining Preset Time (first scheduled time) in the present embodiment to the ratio of AAA message response that is sent to primary radius server during higher than predetermined threshold value, just determine that primary radius server is in normal condition, then just user's AAA business is switched to primary radius server.Compared with prior art, in the present embodiment, pass through to calculate the authentication success rate to AAA message of the primary radius server in certain hour, and then the authentication success rate that obtains of comparing calculation and be preset to power threshold and determine that whether primary radius server is in malfunction, can judge more all sidedly that primary radius server is in malfunction or normal condition, and then can between primary radius server and standby radius server, carry out according to the state of the primary radius server obtaining the switching of AAA business, thereby can reduce in prior art because the mistake to the state of primary radius server is judged, the possibility of the AAA message that the primary radius server causing is cannot normal process a large amount of.

Embodiment 2

The embodiment of the present invention provides a kind of message transmitting method, can be applied in process that BRAS switches to primary radius server by AAA business by standby radius server, and as shown in Fig. 2 or Fig. 3, this message transmitting method, can comprise:

S201, BRAS judge whether to meet pre-conditioned.

Wherein, in the first application scenarios of the embodiment of the present invention, describedly meet pre-conditionedly, be specifically as follows: start timing the default finish time that BRAS switches to AAA business standby radius server by primary radius server from BRAS, and timing time surpassed for second scheduled time.

Or, in the second application scenarios of the embodiment of the present invention, described meet pre-conditioned, be specifically as follows: start timing the default finish time that BRAS switches to AAA business standby radius server by primary radius server from BRAS, within default the 3rd scheduled time, receive the 2nd AAA response from primary radius server.

Wherein, the 2nd AAA response is the response message of primary radius server to the 3rd AAA message, and the 3rd AAA message is that BRAS was sent to the AAA message of primary radius server before described AAA business is switched to standby radius server.

Concrete, in embodiments of the present invention, in the process that BRAS switches to primary radius server by AAA business by standby radius server, BRAS can first send an AAA message to primary radius server according to the first default percentage, and be more than or equal to while being preset to power threshold in the authentication success rate (the authentication success rate of primary radius server is determined in the AAA response that BRAS receives according to first scheduled time) of determining primary radius server, just BRAS determines that primary radius server is in normal condition, the all AAA messages that then just send BRAS to primary radius server (, AAA business is switched to primary radius server by standby radius server).

But, BRAS is when sending an AAA message to primary radius server according to the first default percentage, primary radius server may be temporary in malfunction, therefore, if BRAS at definite primary radius server after malfunction, directly carry out following steps: according to the first default percentage, send an AAA message and send the 2nd AAA message to standby radius server to primary radius server with according to the second default percentage, and now if primary radius server is current in complete fault state, the AAA message that primary radius server sends according to the first default percentage for the BRAS receiving also cannot be processed.In this case, although standby radius server can preset according to second the 2nd AAA message that percentage sends by normal process BRAS, but, because BRAS can not determine whether complete failure of primary radius server, therefore, if primary radius server complete failure now, the AAA message that primary radius server can not normal process BRAS sends according to the first default percentage, the corresponding user of an AAA message cannot normally reach the standard grade.

In the first application scenarios of the embodiment of the present invention, because primary radius server may be temporary in malfunction, in the regular hour, (BRAS switches to AAA business to start default finish time standby radius server timing by primary radius server from BRAS, timing time surpassed for second scheduled time) after, primary radius server may return to normal condition by temporary malfunction, now primary radius server possesses the ability of processing a certain amount of AAA business, therefore, alternatively, BRAS sends an AAA message according to the first default percentage and sends the 2nd AAA message to before standby radius server to primary radius server with according to the second default percentage, can first judge that BRAS switches to AAA business to start default finish time standby radius server timing by primary radius server from BRAS, whether timing time surpassed for second scheduled time, and surpass after second scheduled time at timing time, carry out again S202 and S203, can reduce like this because primary radius server may be in the time (as 5 minutes) in temporary fault state, the possibility that the corresponding user of an AAA message that BRAS is sent to primary radius server according to the first default percentage cannot normally reach the standard grade.

Exemplary, suppose that be 10:00 the default finish time that BRAS switches to AAA business after standby radius server by primary radius server, and second scheduled time can be 15 minutes, BRAS can start timing from 10:00, after timing time surpasses 15 minutes, be that current time surpasses after 10:15, BRAS can determine meet pre-conditioned.

The embodiment of the present invention second in application scenarios, because primary radius server may be temporary in malfunction, therefore, if BRAS is at certain hour, (BRAS switches to AAA business to start default finish time standby radius server timing by primary radius server from BRAS, timing time is default the 3rd scheduled time) in, (the 2nd AAA response is the response message of primary radius server to the 3rd AAA message to receive the 2nd AAA response from primary radius server, the 3rd AAA message is that BRAS was sent to the AAA message of primary radius server before AAA business is switched to described standby radius server), represent that primary radius server possesses the ability of processing a certain amount of AAA business, now BRAS sends an AAA message to primary radius server compared at BRAS, AAA business being switched to while arriving default finish time after standby radius server by primary radius server according to the first default percentage, according to the first default percentage, send an AAA message to primary radius server at once, can reduce because primary radius server may be in the time in temporary fault state, the possibility that the corresponding user of an AAA message that BRAS is sent to primary radius server according to the first default percentage cannot normally reach the standard grade.

Therefore, optionally, BRAS sends an AAA message according to the first default percentage and sends the 2nd AAA message to before standby radius server to primary radius server with according to the second default percentage, can first judge that BRAS switches to AAA business to start default finish time standby radius server timing by primary radius server from BRAS, within default the 3rd scheduled time, whether receive the 2nd AAA response from primary radius server, and in BRAS, within default the 3rd scheduled time, receive after the 2nd AAA response from primary radius server, carry out again S202 and S203, to reduce because primary radius server may be in the time in temporary fault state, the possibility that the corresponding user of an AAA message that BRAS is sent to primary radius server according to the first default percentage cannot normally reach the standard grade.

Exemplary, suppose that be 10:00 the default finish time that BRAS switches to AAA business after standby radius server by primary radius server, and the 3rd scheduled time can be 10 minutes, BRAS can start timing from 10:00, if BRAS receives the 2nd AAA response from primary radius server at 10:00 to any moment between 10:10, BRAS can determine meet pre-conditioned.

It should be noted that, S201 is optional, also can not carry out S201 in embodiments of the present invention, directly carries out S202:BRAS and sends an AAA message to primary radius server and subsequent packet transfer process according to the first default percentage.

Alternatively, if do not meet pre-conditionedly, all AAA messages that send BRAS, to standby radius server, are directly carried out S211:

S202, BRAS send an AAA message to primary radius server according to the first default percentage.

It should be noted that, in embodiments of the present invention, in the process that BRAS switches to primary radius server by AAA business by standby radius server, BRAS sends an AAA message to primary radius server according to the first default percentage, be that BRAS only issues primary radius server by a part of AAA message, authentication success rate for detection of primary RIDIUS server, rather than when starting AAA business to switch to primary radius server by standby radius server, just send all AAA messages to primary radius server, can reduce BRAS in prior art and directly user's AAA business be switched to primary radius server when arrive in default switching time, but the possibility of the AAA message that the primary radius server that primary radius server may still cause in malfunction is cannot normal process a large amount of.

S203, BRAS send the 2nd AAA message to standby radius server according to the second default percentage.

It should be noted that, the first default percentage and the second default percentage sum are 1.The first default percentage and the second default percentage can arrange according to user's input data for BRAS.

S204, BRAS receive the AAA response from primary radius server.

Concrete, primary radius server is after the AAA message receiving from BRAS, can to the corresponding user of each AAA message, carry out corresponding authentication，authorization，accounting respectively, then after completing a user's authentication，authorization，accounting, can send an AAA and respond to BRAS, to notify this primary radius server of BRAS to complete corresponding user's authentication，authorization，accounting.

Wherein, an AAA response is the response message of primary radius server to an AAA message.

S205, BRAS determine the authentication success rate of primary radius server according to the AAA response receiving in first scheduled time.

Wherein, authentication success rate is for characterizing the disposal ability of primary radius server to the corresponding AAA business of an AAA message.

Concrete, due to primary radius server may break down cause cannot normal process or complete failure can not process an AAA message (can not carry out user's authentication，authorization，accounting) that is received from BRAS, primary radius server cannot send or cannot send in time an AAA and responds to BRAS, therefore, BRAS can determine according to the AAA response receiving in first scheduled time authentication success rate of primary radius server.

Exemplary, BRAS determines that according to the AAA response receiving in first scheduled time method of the authentication success rate of primary radius server can comprise: BRAS starts to send an AAA message according to the first default percentage from this BRAS, and extremely the moment of primary radius server starts timing, and statistics moment of starting timing from BRAS play the number of an AAA response and the sum of the AAA message that BRAS is sent to primary radius server that BRAS during this period of time that timing time surpassed for first scheduled time receives, then calculate BRAS and at BRAS, be sent to shared percentage in the sum of an AAA message of primary radius server in the number of a received AAA response of above-mentioned time period, and the authentication success rate using the percentage calculating as primary radius server.

For example, if BRAS within first scheduled time, be sent to primary radius server an AAA message add up to 10, and the number of the AAA response that BRAS receives within first scheduled time is 3, BRAS can determine that the authentication success rate of primary radius server is 30%.

It should be noted that, BRAS can repeatedly add up BRAS and send an AAA message to primary radius server, and primary radius server carries out user's authentication，authorization，accounting, return to an AAA and respond the total time spending to the process of BRAS, then according to first scheduled time of determining total time counting on.

S206, BRAS judge whether authentication success rate is more than or equal to and are preset to power threshold.

It should be noted that, in prior art, if BRAS receives the AAA response from a N continuous AAA message of primary radius server within a certain period of time, BRAS determines that primary radius server is in normal condition, and if BRAS does not receive the AAA response from a N continuous AAA message of primary radius server within a certain period of time, BRAS determines that primary radius server is in malfunction.Because primary radius server may exist a period of time in malfunction, the situation (be in-and-out situation) of a period of time in normal condition, so in prior art may there is the mistake judgement to the state of primary radius server in BRAS when carrying out the condition judgement of primary radius server.

For example, suppose that in the prior art BRAS sends 10 AAA messages and (comprising: AAA message 1-AAA message 10) to primary radius server, and in prior art when BRAS sends and finishes to above-mentioned 10 AAA messages starting to send above-mentioned 10 AAA starts of heading, add in the default stand-by period, if receive 5 continuous AAA responses, can determine that primary radius server is in normal condition.But in the time of may existing primary radius server in the process that receives and process these 10 AAA messages and in normal condition, time and in situation in malfunction, BRAS still judges the problem of primary radius server in normal condition.In this case, if primary radius server when receiving AAA message 1, AAA message 3, AAA message 5, AAA message 7 and AAA message 9 in normal condition, and primary radius server when receiving AAA message 2, AAA message 4, AAA message 6, AAA message 8 and AAA message 10 in malfunction, primary radius server can be processed AAA message 1, AAA message 3, AAA message 5, AAA message 7 and AAA message 9, and returns to AAA response 1, AAA response 3, AAA response 5, AAA response 7 and AAA response 9 to BRAS.Now, although primary radius server when receiving AAA message 2, AAA message 4, AAA message 6, AAA message 8 and AAA message 10 in malfunction, can not return to corresponding AAA responds to BRAS, but BRAS, after receiving AAA response 1, AAA response 3, AAA response 5, AAA response 7 and AAA response 9 these five AAA responses, can determine that primary radius server is in normal condition.But in fact primary radius server is not completely normal.Adopting said method to carry out judging to primary radius server is inaccurate with comprehensive.When primary radius server and in normal condition, time and in situation in malfunction, it is can not normal process a large amount of AAA message, if now judge, primary radius server is in normal condition, and all AAA messages that send BRAS are to primary radius server, may cause the primary radius server can not a large amount of AAA message of normal process, may increase the possibility that a large number of users cannot normally be reached the standard grade.

Compared with prior art, in the embodiment of the present invention, pass through to calculate the authentication success rate to AAA message of the primary radius server in certain hour (the first Preset Time), and then the authentication success rate that obtains of comparing calculation and be preset to power threshold and determine that whether primary radius server is in malfunction, can judge more all sidedly that primary radius server is in malfunction or normal condition, and then can between primary radius server and standby radius server, carry out according to the state of the primary radius server obtaining the switching of AAA business.

It should be noted that, be preset to power threshold and be in BRAS, set in advance for judging the whether success rate threshold value in malfunction of primary radius server.Wherein, BRAS can repeatedly add up in the situation that the authentication success rate of primary radius server is different numerical value, and then the failure condition of primary radius server is determined and be preset to power threshold according to the data that count on; Or the input that BRAS can receive user arranges threshold data, according to the threshold data configuration that arranges of user's input, be preset to accordingly power threshold.In the embodiment of the present invention, to being preset to the concrete numerical value of power threshold and setting or collocation method, do not limit.For example, being preset to power threshold can be 60%.

Concrete, if being greater than or equal to, authentication success rate is preset to power threshold, BRAS determines that primary radius server, in normal condition, continues to carry out S207-S208; If authentication success rate is less than, be preset to power threshold, BRAS determines that primary radius server is in malfunction, continues as shown in Figure 2 to carry out S209 and S210 or continues to carry out as shown in Figure 3 S209 and S211:

S207, BRAS determine that primary radius server is in normal condition.

Wherein, BRAS after normal condition, can switch to primary radius server at definite primary radius server by user's AAA business, carries out S208: send all AAA messages of BRAS to primary radius server.

S208, BRAS send all AAA messages of BRAS to primary radius server.

S209, BRAS determine that primary radius server is in malfunction.

Wherein, BRAS after malfunction, represents that primary radius server does not still possess the ability of a large amount of AAA business of normal process at definite primary radius server.

Now, in a kind of application scenarios of the embodiment of the present invention, BRAS can only issue primary radius server by a part of AAA message, be that BRAS can continue to issue primary radius server primary radius server is carried out to fault detect by sending a part of AAA message, (as shown in Figure 2, carry out S210) and definite primary RIDIUS in Preset Time to the ratio of this part of AAA message response during higher than predetermined threshold value, just determine that primary radius server is in normal condition, then just user's AAA business is switched to primary radius server, thereby the possibility of the AAA message that the primary radius server that can reduce BRAS in prior art directly user's AAA business to be switched to primary radius server when arrive in default switching time and cause is cannot normal process a large amount of.

S210, BRAS send the 4th AAA message to described primary radius server according to the described first default percentage.

It should be noted that, BRAS sends the 4th AAA message according to the described first default percentage and to S202:BRAS in the method for described primary radius server and the embodiment of the present invention, according to the first default percentage, sends an AAA message extremely the method for primary radius server is similar, and the embodiment of the present invention repeats no more here.

Further alternative, under a kind of situation of above-mentioned application scenarios, at BRAS, according to the described first default percentage, send the 4th AAA message to before described primary radius server, the method for the embodiment of the present invention can also comprise: it is pre-conditioned that BRAS judges whether primary radius server meets.

In this case, BRAS sends the 4th AAA message to described primary radius server according to the described first default percentage, be specifically as follows: if meet pre-conditionedly, BRAS sends the 4th AAA message to described primary radius server according to the described first default percentage.

Further alternative, in this case, the method for the embodiment of the present invention can also comprise: if meet pre-conditionedly, BRAS sends the 5th AAA message to standby radius server according to the described second default percentage; If it is pre-conditioned that primary radius server does not meet, carry out S211.

It should be noted that, BRAS sends the 4th AAA message according to the described first default percentage and to S202:BRAS in the concrete grammar of described primary radius server and the embodiment of the present invention, according to the first default percentage, sends an AAA message extremely the concrete grammar of primary radius server is similar, and the embodiment of the present invention repeats no more here; BRAS sends the 5th AAA message according to the described second default percentage and to S203:BRAS in the concrete grammar of standby radius server and the embodiment of the present invention, according to the second default percentage, sends the 2nd AAA message extremely the concrete grammar of standby radius server is similar, and the embodiment of the present invention repeats no more here.

S211, BRAS send all AAA messages of BRAS to standby radius server.

In the another kind of application scenarios of the embodiment of the present invention, BRAS definite primary radius server after the malfunction (representing that primary radius server does not still possess the ability of a large amount of AAA business of normal process) directly by all AAA messages of BRAS to standby radius server, to reduce due to primary radius server fault, can not normal process AAA business, the possibility that causes a large number of users normally not reach the standard grade.

Pass through this programme, can reduce because arrive in default fault time, and primary radius server is still in the situation of fault, BRAS blindly switches to primary radius server by user's AAA business, causes the possibility that a large amount of AAA business can not normal process.In this programme, in the process that AAA business is switched to primary radius server by standby radius server at BRAS, determine after primary radius server fault, only a part of AAA message is issued to primary radius server, and definite primary RIDIUS in Preset Time to the ratio of this part of AAA message response during higher than predetermined threshold value, just determine that primary radius server is in normal condition, then just user's AAA business is switched to primary radius server, thereby the possibility of the AAA message that the primary radius server that can reduce BRAS in prior art directly user's AAA business to be switched to primary radius server when arrive in default switching time and cause is cannot normal process a large amount of.

Further, in this programme, BRAS is before issuing primary radius server by a part of AAA message, can judge whether to meet pre-conditioned, and in meet pre-conditioned after, just a part of AAA message is issued to primary radius server, can further improve at BRAS when a part of AAA message is issued to primary radius server, the possibility of primary radius server in normal condition, thereby can reduce the possibility that primary radius server cannot normal process be sent to a part of AAA message of radius server, and then can improve BRAS and be sent to the possibility that the corresponding user of a part of AAA message of radius server normally reaches the standard grade.
