In step S101, the Operational Visit request that client is sent is received, client mark is carried in Operational Visit request Know.

Wherein, client can be integrated in the terminals such as mobile phone or computer, when needing to execute some business in terminal, Operational Visit request can be sent to access frequency control device by client, access frequency control device receives business visit It asks request, the information such as service identification and client identification can be carried in Operational Visit request.The client identification can be Client name or client number etc. can be made of number, letter and/or word etc., and particular content does not limit here It is fixed.The type of Operational Visit request can be flexibly arranged according to actual needs, for example, it may be mail service access is asked Ask or microblogging Operational Visit request etc., particular content is not construed as limiting here.

It should be noted that the access frequency control device, which can be service server cluster, (is referred to as services sets Group), which may include one or more, wherein multiple service server clusters may include be multiple The service server cluster of different kinds of business service is provided for client, for example, mail service server cluster or microblogging industry Business server cluster etc., it is corresponding to provide mail service or microblogging business etc. to client respectively；Each service server It may include the service server of multiple same types of service in cluster.May include in service server cluster access server and Frequency control proxy server etc., which may include one or more, and it may include one which, which controls proxy server, Or it is multiple.Operational Visit can be asked to turn by service server cluster in the Operational Visit request for receiving client transmission It is initiated onto certain access server, and from the access server to frequency control proxy server (be referred to as frequency and control Agent) Frequency control request so that frequency control proxy server controls the access frequency of client according to frequency control request.

In step s 102, it determines token bucket mark corresponding with client identification, and inquires corresponding with token bucket mark Local token bucket.

In order to effectively control the access frequency of each client, access frequency control device can first pass through mark in advance Know the mapping relations safeguarded between client and local token bucket, that is, establishes the mapping between client identification and token bucket mark Relationship so that there are corresponding local token buckets for each client.Token bucket mark can be token bucket title or order Board bucket number etc. can be made of number, letter and/or word etc., and particular content is not construed as limiting here.

Wherein, token can be stored in local token bucket, local token bucket is mainly used for the access frequency to client It is controlled, for example, can be by indicating whether client can be allowed to access with the presence or absence of token in local token bucket, i.e., If there are tokens in local token bucket, access service can be provided for client, if token is not present in local token bucket, Access service is not provided for client.Each token in local token bucket can be represented as client and provide the service of access Number a, for example, token can provide one or many access services for client；Either, in local token bucket Each token can be represented as the period that client provides the service of access, such as a token can provide 1 for client Access service in second or 3 seconds；Either, each token in local token bucket, which can represent, provides in per second for client The number of service is accessed, i.e., each token in local token bucket can represent the interior number for allowing client to access per second (i.e. access frequency of client) etc..It is understood that the permission that token can represent can carry out spirit according to actual needs Setting living, particular content are not limited thereto.

The course of work of local token bucket may include：Token is generated, token is consumed and determines whether that client provides Access service etc..Wherein, it can periodically increase token into local token bucket with scheduled rate to generate token so that this Token in ground token bucket is on the increase, if token number is more than preset quantity threshold value in local token bucket, can be abandoned more Remaining token.Consumption token can be that the token accessed in consuming local token bucket when service is being provided for client, so as to Client access frequency is counted, which can be the number of interior access per second or the number etc. of interior access per minute.Sentence It is disconnected that whether to provide the service of access for client can be asked when the token quantity in local token bucket can meet Operational Visit When demand of the corresponding business to token, access service can be provided for client, be not otherwise that client provides access and services.

After the Operational Visit request for the carrying client identification for receiving client transmission, access frequency control device can To extract client identification from business access request, and closed according to the mapping between client identification and token bucket mark System determines token bucket mark corresponding with client identification.Then local token bucket corresponding with token bucket mark, inquiry are obtained The local token bucket, the local token bucket can be access frequency control device locally preset token buckets.I.e. when according to local Token in token bucket judges the access frequency of client, for example, when there are when token in local token bucket, it may be determined that client The access frequency at end is less than or equal to predetermined threshold value；When token is not present in local token bucket, it may be determined that the visit of client Ask that frequency is more than predetermined threshold value.

In some embodiments, it determines token bucket mark corresponding with client identification, and inquires and identified with token bucket After the step of corresponding local token bucket, access frequency control method can also include：

When there are when token, obtain the required token of Operational Visit request from local token bucket in local token bucket；Root Corresponding business is asked to provide access service for Operational Visit according to the token got.

For access frequency control device during inquiry local token bucket, when inquiring in local token bucket, there are tokens When, illustrate that the access frequency of the client is less than or equal to predetermined threshold value, business visit can be obtained from local token bucket at this time Ask the token needed for request.Wherein, which can be flexibly arranged according to actual needs, needed for Operational Visit request The quantity of token can be one or more, can be when looking into when the quantity of the token needed for the Operational Visit request is multiple It askes in local token bucket there are when the token needed for Operational Visit request, Operational Visit request institute is obtained from local token bucket The token needed.After getting token, access frequency control device can be Operational Visit request pair according to the token got The business answered provides the service of access.

It should be noted that providing the service of access when each token in token bucket represents in each cycle for client When number, frequency control apparatus is there are when token in inquiring local token bucket, it can be determined that whether current time needs more Token in new local token bucket, for example, if current time still within the current token period, local token bucket will not be updated In token；If current time comes into next new token cycle, business visit is reduced from local token bucket It asks the token needed for request, updates the token in local token bucket.When token is updated successfully, access can be provided for client Service；When token updates failure, preset times can be retried, if success, access service is provided for client, if failure, Then access service is not provided for client, and returns to failure information to client.

In step s 103, when determined according to the token in local token bucket client access frequency be more than predetermined threshold value When, to frequency control server set pocket transmission token application request.

Access frequency control device determines during inquiry local token bucket when according to the token in local token bucket When the access frequency of the client is more than predetermined threshold value, illustrate that the access frequency of the client is larger, for example, when inquiring local When token being not present in token bucket, it may be determined that the access frequency of the client is more than predetermined threshold value；Either, when inquiring this When token in ground token bucket is less than preset quantity, it may be determined that the access frequency of the client is more than predetermined threshold value；Wherein, in advance If quantity and predetermined threshold value can be flexibly arranged according to actual needs, particular content is not construed as limiting here.When according to this When token in ground token bucket determines that the access frequency of client is more than predetermined threshold value, in order to determine whether to increase the client The access frequency at end, access frequency control device can be to frequency control server set pocket transmission token application request at this time.

Wherein, frequency control server cluster can may include one or more, and multiple frequency control server clusters may include The frequency control server cluster of different type frequency control service is provided for multiple service server clusters, each in frequency control server cluster It may include that the frequency control server of multiple same frequency control types, a frequency control server can provide frequency for a service server and control Service.

In some embodiments, may include to the step of frequency control server set pocket transmission token application request：Judge Whether client identification is in preset white list；If client identification controls server set in preset white list, to frequency Pocket transmission token application is asked.

Specifically, access frequency control device can pre-set black and white lists, wherein limitation can be stored in blacklist The corresponding client identification of client of access frequency can only use in local token bucket the client in blacklist Token, when in local token bucket be not present token when, can not to frequency control server set pocket transmission token application request；White list In can store the corresponding client identification of client that can increase access frequency, i.e., for the client in white list, when It, can be to frequency control server set pocket transmission token application request when token being not present in local token bucket.

It is understood that access frequency control device can also pre-set unlimited access list and forbid accessing list Deng, wherein the client in unlimited access list can infinitely number access, and do not control its access frequency, prohibiting The client only accessed in list cannot access.

When determining that the access frequency of client is more than predetermined threshold value according to the token in local token bucket, access frequency control Whether device processed may determine that client identification in preset white list；If client identification in preset white list, To frequency control server set pocket transmission token application request.If client identification is not in preset white list, not to frequency control clothes Business device collection pocket transmission token application request is refused to provide access service for the corresponding client of the client identification.

Optionally, it if client identification is in preset white list, is asked to frequency control server set pocket transmission token application The step of asking may include：When client identification is in preset white list, token is produced in predetermined period；When production When token cannot meet the token needed for Operational Visit request, to frequency control server set pocket transmission token application request.

Specifically, the token in local token bucket can be that frequency control server cluster is pre-assigned, can also be local What token bucket produced in advance, the token quantity in the corresponding local token bucket of different clients can carry out according to actual needs Flexibly setting.When client identification is in preset white list, illustrate that the corresponding client of the client identification can increase Access frequency, access frequency control device can produce the token of preset quantity every predetermined period, and access frequency controls at this time Device produces token in predetermined period.When the token of production cannot meet the required token of Operational Visit request, frequency is accessed Rate control device can be to frequency control server set pocket transmission token application request.

In some embodiments, when determining that it is default that the access frequency of client is more than according to the token in local token bucket When threshold value, to after the step of frequency control server set pocket transmission token application request, access frequency control method can also include：

When there is no when token, receive frequency control server cluster to be based in the token bucket that frequency control server cluster inquiry prestores The token application failure information that token application request returns；Based on token application failure information, refuse as Operational Visit request pair The business answered provides the service of access.

Specifically, after access frequency control device is asked to frequency control server set pocket transmission token application, frequency control service Device cluster, which can be inquired, whether there is token in the token bucket to prestore, which is that frequency control server cluster is pre-set, Token can be stored in token bucket, the representative meaning of token and the course of work of token bucket and local token in the token bucket Bucket it is similar, repeat no more here.When frequency control server cluster inquires, and token is not present in token bucket, illustrate current each Client access frequency is larger, this time-frequency control server cluster is asked to return to access frequency control device and be enabled based on token application Board application failure information, access frequency control device receive the token application failure information.Access frequency control device is receiving To after token application failure information, can refuse to ask corresponding business to provide access service for Operational Visit.So as to have The solution of effect neatly limits the access frequency of client, to protect when client traffic uprushes (i.e. access frequency is uprushed) Protect the safety and stabilization of access frequency control device (i.e. service server cluster).

It should be noted that frequency control server cluster can ask after receiving token application request from token application In extract Operational Visit request need access service server mark, according to pre-set service server mark with frequency The mapping relations between server identification are controlled, determine frequency control server identification corresponding with service server mark, from frequency control clothes It is engaged in obtaining the corresponding frequency control server of frequency control server identification in device cluster.Frequency control server can inquire the token bucket to prestore In token, when the frequency control server inquire in token bucket be not present token when, frequency control server to access frequency control fill The token application failure information for setting return, when frequency control server inquires, and token is not present in token bucket, frequency controls server The token needed for token application request is returned to access frequency control device.

In step S104, the token that frequency control server cluster is returned based on token application request is received, and according to obtaining Token ask corresponding business to provide access service for Operational Visit.

After access frequency control device is asked to frequency control server set pocket transmission token application, frequency controls server cluster can It whether there is token in the token bucket that prestores to inquire, when frequency control server cluster inquires in token bucket there are when token, frequency Control server cluster asks to return to token to access frequency control device based on token application.Access frequency control device receives frequency The token that server cluster returns is controlled, and asks corresponding business to provide access service for Operational Visit according to obtained token. The preset local token bucket of access frequency control device can effectively share the load that frequency controls server cluster so that access frequency There are one bufferings between rate control device and frequency control server cluster, reduce access time of the client to frequency control server cluster Number can greatly reduce the pressure that frequency controls server cluster, can support the access buckles of bigger, while when frequency control server set When group is gone wrong, access frequency control device can control the access frequency of client by local token bucket, maximum possible Reduce the fault-tolerance of access frequency control device.

It should be noted that the access frequency control device can be service server cluster, in service server cluster May include access server and frequency control proxy server etc., it may include frequency control logical group and storage that frequency, which controls server cluster, Server cluster (also referred to as storage cluster) etc., wherein the access server in service server cluster and frequency control agency service In the quantity of device etc., and frequency control server cluster intermediate frequency control logical group and the quantity of storage server cluster can be according to reality Border needs flexibly to be arranged.For example, as shown in figure 3, client can be asked to service server collection pocket transmission Operational Visit, Operational Visit is asked the access server in load balancing to service server cluster by service server cluster.Receiving industry After access request of being engaged in, frequency control proxy server of the access server into service server cluster sends frequency control request.It is receiving To after frequency control request, frequency controls the local token bucket of proxy server inquiry.When determining client according to the token in local token bucket Access frequency be more than predetermined threshold value when, frequency control proxy server to frequency control server cluster in frequency control logical group send enable Board application is asked.After receiving token application request, frequency controls storage server of the logical group into frequency control server cluster Collect the update request of pocket transmission token.After receiving token update request, storage server cluster inquires the token bucket to prestore.When Storage server cluster inquiry token bucket in there are when token, reduced from token bucket token application request needed for token, And return to update result to frequency control logical group.After receiving update result, frequency controls logical group and controls proxy server to frequency Return to the token needed for token application request.The token received is stored in local token bucket by frequency control proxy server, and from originally The token needed for Operational Visit request is reduced in ground token bucket, and reduces token as a result, so that connecing to access server return Enter server asks corresponding business to provide access service for Operational Visit, with the corresponding business of processing business access request.

In some embodiments, corresponding business is asked to provide the service of access for Operational Visit according to obtained token Step may include：

Obtained token is stored to local token bucket；The order needed for Operational Visit request is obtained from local token bucket Board；According to the token needed for the Operational Visit request got, corresponding business is asked to provide access service for Operational Visit.

Specifically, access frequency control device is receiving order of the frequency control server cluster based on token application request return Bridge queen counts for the ease of the access frequency to client, can store obtained token to local token bucket；Then The token needed for Operational Visit request is obtained from local token bucket, and client is counted according to the token consumed in local token bucket The access frequency at end, and can be asked for Operational Visit corresponding according to the token needed for the Operational Visit request got Business provides the service of access, the i.e. corresponding business of processing business access request.

Optionally, the step of Operational Visit asks required token is obtained from local token bucket may include：Judgement is worked as Whether the preceding moment is within the current token period；If current time not within the current token period, obtains from local token bucket Token needed for Operational Visit request updates the token quantity in local token bucket.

Can be the token setting term of validity in local token bucket, the term of validity of a token can be using primary or more It is secondary, or use within a preset period of time.Frequency control apparatus is obtained from local token bucket needed for Operational Visit request Token when, it can be determined that whether current time needs to update the token quantity in local token bucket, that is, judges that current time is It is no within the current token period, if current time within the current token period, need not update the order in local token bucket Board quantity；If current time comes into next token cycle, Operational Visit request is reduced from local token bucket Required token updates the token quantity in local token bucket.When token quantity is updated successfully, visit can be provided for client The service of asking；When token quantity updates failure, preset times can be retried, if success, access service is provided for client, if Failure does not then provide access service for client, and returns to failure information to client.

From the foregoing, it will be observed that Operational Visit request of the embodiment of the present invention in the carrying client identification for receiving client transmission When, it may be determined that token bucket mark corresponding with client identification, and inquire local token bucket corresponding with token bucket mark；When When determining that the access frequency of client is more than predetermined threshold value according to the token in local token bucket, server set pocket transmission is controlled to frequency Token application is asked；Then the token that frequency control server cluster is returned based on token application request is received, and according to obtained order Board asks corresponding business to provide access service for Operational Visit.The program can safeguard each client according to client identification Token in corresponding local token bucket, and the token in the token bucket to prestore is safeguarded by frequency control server cluster, pass through Token in token bucket control effectively to the access frequency of client, improve access frequency is controlled it is accurate Property.

Referring to Fig. 4, Fig. 4 is the flow diagram of access frequency control method provided in an embodiment of the present invention.This method Flow may include：

201, client is asked to service server collection pocket transmission Operational Visit, and service server cluster asks Operational Visit Seek the access server in load balancing to service server cluster.

When needing to execute some business, client can be asked to service server collection pocket transmission Operational Visit, the industry The information such as service identification and client identification can be carried in business access request.Wherein, service identification can serve to indicate that the industry The corresponding type of service of access request of being engaged in, the Operational Visit ask corresponding type of service that can carry out according to actual needs flexibly Setting, for example, it may be mail service access request or the request of microblogging Operational Visit etc., particular content is not construed as limiting here. The service identification can be Business Name or business number etc., can be made of number, letter and/or word etc., particular content It is not construed as limiting here.The client identification is used to indicate client, which can be client name or client End number etc. can be made of number, letter and/or word etc., and particular content is not construed as limiting here.Service server cluster After receiving Operational Visit request, Operational Visit can be asked to the access service in load balancing to service server cluster On device.

202, after receiving Operational Visit request, frequency control agency service of the access server into service server cluster Device sends frequency control request.

Access server, can be to the frequency control agency service in service server cluster after receiving Operational Visit request Device sends frequency control request, and frequency control request can carry the information such as service identification and client identification, so that frequency control agency Server controls the access frequency of client according to frequency control request.

203, after receiving frequency control request, frequency controls the local token bucket of proxy server inquiry.

Frequency control proxy server can extract client identification after receiving frequency control request from frequency control request, and According to the mapping relations between the client identification pre-established and token bucket mark, token corresponding with client identification is determined Bucket mark.Then local token bucket corresponding with token bucket mark is obtained, inquires the local token bucket, which can be with It is frequency control proxy server locally preset token bucket.

Wherein, if there are tokens in local token bucket, access service can be provided for client, if in local token bucket There is no tokens, then do not provide access service for client.Each token in local token bucket can be represented as client The number of the service of access is provided, either, each token in local token bucket can be represented as client and provide access clothes The period of business, either, each token in local token bucket can represent in per second and provide access service for client Number (i.e. the access frequency of client) etc..It is understood that the permission that token can represent can be according to actual needs Flexibly it is arranged, particular content is not limited thereto.

For frequency control proxy server during inquiry local token bucket, when inquiring in local token bucket, there are tokens When, the token needed for Operational Visit request can be obtained from local token bucket.After getting token, frequency controls proxy server The token needed for Operational Visit request is reduced from local token bucket, and the token reduced is returned into access server, is accessed Server can ask corresponding business to provide access service according to obtained token for Operational Visit.

It should be noted that providing the service of access when each token in token bucket represents in each cycle for client When number, for example, per second access 1000 times, frequency control proxy server in inquiring local token bucket there are when token, if Current time within the current token period, then can not update the token (not reducing token) in local token bucket；If worked as The preceding moment comes into next token cycle, then the token needed for Operational Visit request, update are reduced from local token bucket Token in local token bucket.For example, it is assumed that allowing client is per second to access 1000 times, the current token period is the 50th second, such as Fruit current time in the 50th second, does not then reduce token；If current time enters the 51st second, token is reduced.When token more When new success, access service can be provided for client；When token updates failure, preset times can be retried, if success, Access service is provided for client, if failure, does not provide access service for client, and return to failure information to client. For not used token, frequency is controlled proxy server and can directly be abandoned, can also return to local token bucket.

It should be noted that frequency control proxy server can not only consume token, token can also be produced, for example, such as Fig. 5 Shown, frequency controls proxy server as the producer, can be periodically with scheduled rate production token, and by the token of production It stores into local token bucket (i.e. token bucket in Fig. 5), which can be the shared interior of frequency control proxy server It deposits, which can be the data structure of the local token bucket of storage；Either, frequency control proxy server is periodically to frequency Server cluster application token is controlled, and connects the token applied and is written in shared drive.Wherein, frequency control user can be made With the equipment of access frequency control method, such as the access server etc. of consumption token, frequency, which controls user, can pass through multi-process Or multithreading isotype consumes token.For example, when needing the access frequency to client to control, frequency controls user can be with Concurrently or sequentially frequency is asked to be controlled to shared drive by process 1, process 2, process 3 and process 4 etc., so as to out of share Deposit the token needed for acquisition.

Specifically, the process for consuming token can be as follows：It, can be to shared drive when frequency control user needs to consume token Apply for token number, if the token number in shared drive is 0, directly returning to frequency control user's frequency control transfinites, if in shared Token number in depositing is not 0, then frequency control user can apply to token, and execute subsequent operation.If token number is not 0 When, then shared drive also need to update token return to client if token is updated successfully and be updated successfully information；If Token update failure, then can retry certain number, if success, returns to client and be updated successfully information, if failure, returns Client updates failure information.If request frequency is controlled required token and is not present, frequency controls user and is notified that frequency control agency Server produces token, production token is removed in some cycles by frequency control proxy server, frequency controls proxy server can be in token The update of token is safeguarded in period.

204, when determining that the access frequency of client is more than predetermined threshold value according to the token in local token bucket, frequency controls generation It manages the frequency control logical group that server is controlled to frequency in server cluster and sends token application request.

Frequency control proxy server, should when being determined according to the token in local token bucket during inquiry local token bucket When the access frequency of client is more than predetermined threshold value, illustrate that the access frequency of the client is larger, for example, when inquiring local order When token being not present in board bucket, it may be determined that the access frequency of the client is more than predetermined threshold value；Either, when inquiring local When token in token bucket is less than preset quantity, it may be determined that the access frequency of the client is more than predetermined threshold value；Wherein, it presets Quantity and predetermined threshold value can be flexibly arranged according to actual needs, and particular content is not construed as limiting here.When according to local When token in token bucket determines that the access frequency of client is more than predetermined threshold value, frequency controls proxy server and controls server set to frequency Frequency control logical group in group sends token application request, and required token quantity, industry can be carried in token application request The information such as business mark and client identification.

It should be noted that frequency control proxy server can also pre-set black and white lists, wherein in blacklist Client can only use the token in local token bucket, can not be to frequency control service when token is not present in local token bucket Device collection pocket transmission token application is asked；It, can be with when token is not present in local token bucket for the client in white list To frequency control server set pocket transmission token application request.

When determining that the access frequency of client is more than predetermined threshold value according to the token in local token bucket, frequency control agency's clothes Whether business device may determine that client identification in preset white list；If client identification in preset white list, to Frequency control logical group in frequency control server cluster sends token application request.If client identification is not in preset white list In, then refuse to provide access service for the corresponding client of the client identification.

205, after receiving token application request, frequency controls storage server of the logical group into frequency control server cluster Collect the update request of pocket transmission token.

Wherein, storage server cluster is mainly responsible for access frequency situation of the storage client within the time cycle, storage Key assignments (Key-Value) storage (i.e. KV storages) system can be used to store client access frequency in server cluster.Frequency control is patrolled The granting of token can be responsible for, the storage of frequency control number, management frequency control strategy, black and white lists control, be directed to client by compiling group Personalized control (such as certain clients can reduce access frequency, and certain clients can increase access frequency, Ke Yijin The only access etc. of certain user) and management and the interaction of storage server cluster.After receiving token application request, frequency It controls the storage server collection pocket transmission token that logical group can be controlled to frequency in server cluster and updates request, token update is asked The information such as token quantity, service identification and client identification can be carried in asking, and enabled to be obtained from storage server cluster Board.

For example, as shown in fig. 6, access for customer end A in the time cycle 1, frequency controls logical group can be in week time Apply for token 1 to storage server cluster (and storage server cluster) according to token identifications 1 in phase 1, i.e., to storage server Collect pocket transmission token 1 and update request, storage server cluster can store customer end A in week time according to token identifications 1 at this time Access frequency situation in phase 1, the token identifications 1 can identify customer end A the time cycle 1 access times.Similarly, exist The access of time cycle 2, the access in the time cycle 3, the access in the time cycle 4 and the access etc. in the time cycle 5, Can be similar with the access in the time cycle 1, details are not described herein.

206, after receiving token update request, storage server cluster inquires the token bucket to prestore.

Storage server cluster can be previously stored with token bucket, and the token bucket is mainly in conjunction with frequency control proxy server Local token bucket controls the access frequency of client, and storage server cluster can be produced at interval of preset period of time Token, and token is stored into token bucket, if there are tokens in token bucket, access service can be provided for client, if Token is not present in token bucket, then does not provide access service for client.Each token in token bucket can be represented as visitor Family end provides the number of the service of access, and either, each token in token bucket can be represented as client and provide access clothes The period of business, either, each token in token bucket can represent time for providing the service of access in per second for client Number (i.e. the access frequency of client) etc..It is understood that the permission that token can represent can carry out according to actual needs Flexibly setting, particular content are not limited thereto.

Storage server cluster can inquire the token bucket to prestore, to judge token after receiving token update request It whether there is token in bucket.

207, when there are when token, reduce token application from token bucket to ask in the token bucket of storage server cluster inquiry Required token is sought, and update result is returned to frequency control logical group.

Storage server cluster, which can be inquired, whether there is token in the token bucket to prestore, when storage server cluster is inquired To, there are when token, storage server cluster can reduce the token needed for token application request from token bucket in token bucket, And update is returned as a result, the token needed for token update request, i.e. base can be carried in the update result to frequency control logical group In token update request token is returned to frequency control logical group.Frequency control logical group receives the order of storage server cluster return The token can be sent to frequency control proxy server by bridge queen.

When token is not present in the token bucket that the inquiry of storage server cluster prestores, can be returned to frequency control logical group Token application failure information, frequency control logical group and token application failure information are sent to access clothes by frequency control proxy server Business device, access server are refused to ask corresponding business to provide for Operational Visit based on the token application failure information received Access service.

For example, the access frequency for customer end A controls, it is assumed that control strategy is that customer end A is allowed to be accessed in 1 second 1000 times, when customer end A accesses in 1 second there are 1001 times, i.e., have in unix timestamps 1,510,112,115 1001 times When access, then in storage server cluster, the storage organization of the customer end A can be key：1510112115_1, value： 1001；Wherein, when receiving the 1001st Operational Visit request of customer end A transmission, the meeting backward reference frequency transfinites, while visitor The access denied of family end A achievees the purpose that precisely frequency is controlled.

208, after receiving update result, frequency control logical group returns to token application to frequency control proxy server and asks institute The token needed.

Frequency control logical group can extract token, and control to frequency after receiving update result from update result Proxy server returns to the token needed for token application request.The preset local token bucket of frequency control proxy server is had The load of effect shared frequency and control server cluster, reduces the access times that client controls frequency server cluster, can subtract significantly Few frequency controls the pressure of server cluster, can support the access buckles of bigger, while when frequency control server cluster goes wrong, industry Being engaged in server cluster can be by the access frequency of local token bucket control client, the reduction service server collection of maximum possible The fault-tolerance of group.

209, the token received is stored in local token bucket by frequency control proxy server, and reduces industry from local token bucket Token needed for access request of being engaged in.

Frequency control proxy server, can be with after receiving the token needed for the token application request that frequency control logical group returns Obtained token is stored to local token bucket；Then the token needed for Operational Visit request, root are reduced from local token bucket The access frequency of client is counted according to the token consumed in local token bucket.

The term of validity can be arranged in token in local token bucket, and the term of validity of a token can be using primary or more It is secondary, or use within a preset period of time.Frequency control proxy server obtains Operational Visit request institute from local token bucket When the token needed, if current time within the current token period, can not reduce the token in local token bucket；If worked as The preceding moment comes into next token cycle, then the order needed for Operational Visit request can be reduced from local token bucket Board.

210, frequency control proxy server generates frequency control as a result, and returning to frequency control result to access server.

Frequency control proxy server can generate frequency control according to the token reduced as a result, can carry permission in frequency control result The information of client access and token etc. return to frequency control result to access server.

211, after receiving frequency control result, access server asks corresponding business to provide access clothes for Operational Visit Business, with the corresponding business of processing business access request.

For access server after receiving frequency control result, it can be client that the information determination carried in result can be controlled according to frequency When end provides access service, the required token of Operational Visit request can be extracted from frequency control result, be that business is visited by token Ask that the corresponding business of request provides the service of access, with the corresponding business of processing business access request.

212, access server returns to service processing result to client.

Access server can generate service processing result after the corresponding business of processing business access request, and to visitor Family end returns to service processing result.

The embodiment of the present invention can be when service server cluster be accessed by high frequency, using token bucket to different clients Access frequency control effectively, and so as to protect the safety of service server cluster, and improves to access frequency The accuracy controlled.Also, it can effectively share frequency control using the preset local token bucket of frequency control proxy server to take The load of business device cluster so that there are one buffering, reduction clients pair between service server cluster and frequency control server cluster Frequency controls the access times of server cluster, can greatly reduce the pressure that frequency controls server cluster.
