Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of a main flow of a method for adjusting a traffic quota according to a first embodiment of the present invention; as shown in fig. 1, a method for adjusting a traffic quota according to an embodiment of the present invention mainly includes:
step S101, receiving one or more flow transmission requests, and determining a user identifier according to request information in the flow transmission requests for each flow transmission request; the traffic transmission request comprises an access request sent by a client in the current traffic transmission request and a response request returned by the target server.
Specifically, according to the embodiment of the present invention, for the multiple traffic transmission requests, the multiple traffic transmission requests may be sent by one network terminal, or may be sent by multiple network terminals, and one network terminal (e.g., a client) may initiate multiple traffic transmission requests at the same time.
Further, according to the embodiment of the present invention, an interaction between the client and the target server is involved in one traffic transmission process, and the traffic value in the subsequent determination of the current traffic transmission process is also referred to as a traffic value generated in one interaction process (request and response).
Illustratively, the request information includes information such as a user number, an IP address, and a port number, and a unique user identifier is determined according to the request information, which is helpful for subsequently determining a data object corresponding to the user identifier, so as to perform statistics on a traffic value in a traffic transmission process.
Step S102, searching from the data object set according to the user identification to determine a first data object, and acquiring a corresponding address of the first data object in the data object set; the data object is used for indicating the corresponding relation between the user identification and the flow value correspondingly transmitted by the user identification.
Through the setting, the first data object is determined from the data object set according to the unique user identifier corresponding to the flow transmission request, the flow value in the flow transmission request is counted on the basis of the flow value counted by the data object, the total flow value corresponding to the user in the process of multiple flow transmission requests is determined conveniently, and the flow quota is adjusted conveniently subsequently. On the other hand, the address of the first data object corresponding to the data object set is obtained, which is helpful for directly writing the traffic value counted in the current traffic transmission process into the address, namely directly writing the traffic value into the first data object corresponding to the user identifier in the data object set, so that the real-time counting of the traffic value is realized, the counting efficiency of the traffic value is improved, and the adjustment efficiency of the traffic quota is further improved.
Further, according to the embodiment of the present invention, if it is determined that the first data object corresponding to the user identifier does not exist in the process of searching the data object set, the method further includes:
creating a second data object according to the user identification;
and performing statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the second data object, and writing the statistical operation result into the second data object.
In the actual implementation process, after the user identifier is determined, firstly, whether a first data object corresponding to the user identifier exists in a data object set is inquired and judged, and if the first data object exists, a corresponding address of the first data object in the data object set is obtained; if not, the first data object corresponding to the user identifier is not existed in the data object set, that is, the client corresponding to the user identifier has not initiated the request for the excessive flow transmission and has not generated the excessive flow value, at this time, the second data object is reconstructed according to the user identifier and is used as the data object for the flow value statistics in the current transmission process. Through the arrangement, even if the client initiating the flow transmission request does not have a corresponding data object in the data object set, the flow value statistics can be carried out by establishing the data object, and then the data object set is updated according to the second data object, so that the statistical efficiency and the statistical accuracy of the flow value are ensured, and meanwhile, even if a plurality of flow transmission requests initiated by the client corresponding to the user identification are received, the flow value corresponding to each flow transmission request can be simultaneously counted, the iterative statistics is carried out on the total flow value, the statistical efficiency is improved, and the statistical error is avoided.
Preferably, according to an embodiment of the present invention, after the step of writing the result of the statistical operation into the second data object, the method further includes:
judging whether a data object corresponding to the user identifier exists in the data object set or not;
if so, acquiring an address corresponding to the data object corresponding to the user identifier in the data object set, and writing the flow value counted in the second data object into the address;
and if not, locking the data object set, and inserting the second data object into the data object set successfully subjected to locking.
In a specific embodiment, in the process of constructing a new data object (i.e., a second data object) according to a user identifier, a data object corresponding to the user identifier may have been inserted into a data object set by other statistical units, and in order to avoid that multiple data objects exist in the data object set for the same user identifier, before inserting a newly constructed target data object into the data object set, it is necessary to determine again whether a data object corresponding to the user identifier exists in the data object set.
According to another specific implementation manner of the embodiment of the present invention, since the same client may initiate multiple traffic transmission requests simultaneously, at this time, second data objects are respectively constructed for the user identifier corresponding to each traffic transmission request, that is, before inserting a data object set, multiple second data objects may have been constructed for the same user identifier, if a second data object is directly inserted into the data object set, after the client initiates a traffic transmission request again, multiple data objects corresponding to the user identifier may be queried in the data object set, so that complexity of determining a target data object is increased, a difficulty coefficient is further added to summarization of a total traffic value corresponding to the user identifier, and more statistical time of the traffic value is consumed. Therefore, when the newly constructed second data object is inserted into the data object set, the data object set needs to be locked, and after the locking is successful, the newly constructed second data object is inserted into the data object set.
Through the setting, before the flow value statistics is executed, the data object corresponding to the user identifier is effectively ensured to exist, and the flow value generated by the client corresponding to the user identifier in the flow transmission process is counted (if the data set has the first data correspondence, the flow value counted in the current flow transmission process is directly summarized to the original flow value counted according to the address of the first data object), so that the real-time performance of the flow statistics is ensured, and the adjustment efficiency of the flow quota is improved.
Illustratively, according to the embodiment of the present invention, the locking processing on the data object set and the inserting the second data object into the data object set successfully subjected to the locking processing include:
locking the data object set, and judging whether the locking is successful;
and if the locking processing fails, placing the second data object in the candidate queue, so that the candidate queue performs locking processing on the data object set again until the locking processing is successful.
Specifically, when the locking fails, the target data object to be inserted into the data object set is placed in the candidate queue, so that the locking processing is performed subsequently.
Further, according to the embodiment of the present invention, if the locking process is successful, the method further includes:
judging whether a data object corresponding to the user identifier exists in the data object set which is successfully locked again according to the user identifier;
if the traffic value exists, taking a data object corresponding to the user identifier in the data object set as a target data object, and writing the traffic value counted in the second data object into the target data object;
and if not, inserting the second data object into the data object set.
In specific implementation, when the locking process may be performed last time, corresponding data objects are inserted for the same user identifier, and in order to ensure that only the uniquely corresponding data object exists for the same user identifier in the data object set, it is necessary to query and determine whether the data object corresponding to the user identifier exists in the data object set again. If the data object exists, taking the data object corresponding to the user identifier in the data object set as a target data object corresponding to the user identifier, namely updating the target data object and acquiring the address of the target data object; and if the flow value does not exist, inserting a second data object which is newly created and completes the flow value statistics in the current flow transmission process into the data object set, and updating the data object set.
Step S103, performing a statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object, and writing a statistical operation result into an address of the first data object in the data object set.
Specifically, according to the embodiment of the present invention, the performing a statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object includes:
and counting the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object in an atomic operation mode.
Atomic operations refer to operations that are not interrupted by a thread scheduling mechanism, and once started, run to the end without switching to another thread in the middle. Counting in an atomic operation mode: when multiple threads add operations to the same counter (the traffic values counted by multiple traffic transmission requests initiated by the same client are superimposed on the original statistical value of the same data object), if the locking is not performed, the counter value (the superimposed total statistical value) is inaccurate, and if the locking operation is performed to the same counter value, multiple threads compete for the same lock, so that the calculation efficiency is reduced. By using the atomic operation, an operation lock is not needed, the calculation operation is completed by the compiler and the hardware, the calculation performance is improved, and the realization of the logic is simpler.
According to the embodiment of the present invention, in a specific implementation, the same client may initiate multiple traffic transmission requests at the same time, that is, multiple statistical units all obtain data object addresses corresponding to the same user identifier from a data object set, and write corresponding traffic values into the corresponding addresses in the traffic transmission process of each statistical unit. Through atomic operation, multiple writing of the same data object is realized, and errors in writing (summarizing, and overlaying of newly written data to the original statistical flow value) of multiple statistical values are avoided.
And step S104, adjusting the flow quota corresponding to each data object according to the flow quota strategy and the flow value of each data object in the data object set.
The proxy server establishes a flow quota policy according to network bandwidth, data of a network terminal (client) initiating access and the like, adjusts a flow quota (residual flow quota) corresponding to each data object in a data object set by combining flow values (a total flow value updated in real time and including a flow value generated in each flow transmission process) corresponding to each data object, and executes corresponding operations (such as warning, current limiting and the like) according to the flow quota of each data object.
According to the technical scheme of the embodiment of the invention, one or more flow transmission requests are received, and the user identification is determined according to the request information in the flow transmission request aiming at each flow transmission request; the flow transmission request comprises an access request sent by a client in the current flow transmission request and a response request returned by a target server; searching from the data object set according to the user identification to determine a first data object, and acquiring a corresponding address of the first data object in the data object set; the data object is used for indicating the corresponding relation between the user identification and the flow value correspondingly transmitted by the user identification; carrying out statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object, and writing the statistical operation result into the address of the first data object corresponding to the data object set; the technical means of adjusting the flow quota corresponding to each data object according to the flow quota policy and the flow value of each data object in the data object set overcome the technical problems of dependence on the performance of an external database, low adjustment efficiency and low accuracy of the adjusted flow quota in the existing method, and further achieve the technical effects of improving the flow statistical efficiency, improving the efficiency of adjusting the flow quota and ensuring the accuracy of the adjusted flow quota.
Fig. 2 is a schematic diagram of a main flow of a method for adjusting a traffic quota according to a second embodiment of the present invention; as shown in fig. 2, a method for adjusting a traffic quota according to an embodiment of the present invention mainly includes:
step S201, receiving one or more traffic transmission requests, and determining a user identifier according to request information in the traffic transmission request for each traffic transmission request. The traffic transmission request comprises an access request sent by a client in the current traffic transmission request and a response request returned by the target server.
Specifically, according to the embodiment of the present invention, for the multiple traffic transmission requests, the multiple traffic transmission requests may be sent by one network terminal, or may be sent by multiple network terminals, and one network terminal (e.g., a client) may initiate multiple traffic transmission requests at the same time.
Illustratively, the request information includes information such as a user number, an IP address, and a port number, and a unique user identifier is determined according to the request information, which is helpful for subsequently determining a data object corresponding to the user identifier, so as to perform statistics on a traffic value in a traffic transmission process.
Further, according to a specific implementation manner of the embodiment of the present invention, a state machine in the proxy server may be used to receive the traffic transmission request, and a traffic value generated by an interaction (including a request of the client and a response of the server) between the client and the server is counted by the state machine.
Step S202, searching from the data object set according to the user identification, and judging whether a first data object corresponding to the user identification exists. If yes, go to step S203; if not, go to step S204.
Specifically, the data object is used to indicate the correspondence between the user identifier and the traffic value correspondingly transmitted by the user identifier.
Step S203, acquiring the corresponding address of the first data object in the data object set, performing a statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object, and writing the statistical operation result into the corresponding address of the first data object in the data object set.
Through the setting, the first data object is determined from the data object set according to the unique user identifier corresponding to the flow transmission request, the flow value in the flow transmission request is counted on the basis of the flow value counted by the data object, the total flow value corresponding to the user in the process of multiple flow transmission requests is determined conveniently, and the flow quota is adjusted conveniently subsequently. On the other hand, the address of the first data object corresponding to the data object set is obtained, which is helpful for directly writing the traffic value counted in the current traffic transmission process into the address, namely directly writing the traffic value into the first data object corresponding to the user identifier in the data object set, so that the real-time counting of the traffic value is realized, the counting efficiency of the traffic value is improved, and the adjustment efficiency of the traffic quota is further improved.
Step S204, creating a second data object according to the user identification; and performing statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the second data object, and writing the statistical operation result into the second data object.
In the actual implementation process, after the user identifier is determined, firstly, whether a first data object corresponding to the user identifier exists in a data object set is inquired and judged, and if the first data object exists, a corresponding address of the first data object in the data object set is obtained; if not, the first data object corresponding to the user identifier is not existed in the data object set, that is, the client corresponding to the user identifier has not initiated the request for the excessive flow transmission and has not generated the excessive flow value, at this time, the second data object is reconstructed according to the user identifier and is used as the data object for the flow value statistics in the current transmission process. Through the arrangement, even if the client initiating the flow transmission request does not have a corresponding data object in the data object set, the flow value statistics can be carried out by establishing the data object, and then the data object set is updated according to the second data object, so that the statistical efficiency and the statistical accuracy of the flow value are ensured, and meanwhile, even if a plurality of flow transmission requests initiated by the client corresponding to the user identification are received, the flow value corresponding to each flow transmission request can be simultaneously counted, the iterative statistics is carried out on the total flow value, the statistical efficiency is improved, and the statistical error is avoided.
According to a specific implementation manner of the embodiment of the present invention, in order to distinguish between a first data object (already stored in the data object set) and a second data object (newly created and not yet inserted into the data object set), the first data object and the second data object may be distinguished according to a parameter in db of the data object, and for the data object already stored in the data object set, an in db parameter is true; if not already stored in the set of data objects (e.g., the newly created second data object), the in db parameter is false.
Step S205, judging whether a data object corresponding to the user identification exists in the data object set; if so, acquiring an address corresponding to the data object corresponding to the user identifier in the data object set, and writing the flow value counted in the second data object into the address; and if not, locking the data object set, and inserting the second data object into the data object set successfully subjected to locking.
In a specific embodiment, in the process of constructing a new data object (i.e., a second data object) according to a user identifier, a data object corresponding to the user identifier may have been inserted into a data object set by other statistical units, and in order to avoid that multiple data objects exist in the data object set for the same user identifier, before inserting a newly constructed target data object into the data object set, it is necessary to determine again whether a data object corresponding to the user identifier exists in the data object set.
According to another specific implementation manner of the embodiment of the present invention, since the same client may initiate multiple traffic transmission requests simultaneously, at this time, second data objects are respectively constructed for the user identifier corresponding to each traffic transmission request, that is, before inserting a data object set, multiple second data objects may have been constructed for the same user identifier, if a second data object is directly inserted into the data object set, after the client initiates a traffic transmission request again, multiple data objects corresponding to the user identifier may be queried in the data object set, so that complexity of determining a target data object is increased, a difficulty coefficient is further added to summarization of a total traffic value corresponding to the user identifier, and more statistical time of the traffic value is consumed. Therefore, when the newly constructed second data object is inserted into the data object set, the data object set needs to be locked, and after the locking is successful, the newly constructed second data object is inserted into the data object set.
Through the setting, before the flow value statistics is executed, the data object corresponding to the user identifier is effectively ensured to exist, and the flow value generated by the client corresponding to the user identifier in the flow transmission process is counted (if the data set has the first data correspondence, the flow value counted in the current flow transmission process is directly summarized to the original flow value counted according to the address of the first data object), so that the real-time performance of the flow statistics is ensured, and the adjustment efficiency of the flow quota is improved.
Illustratively, according to the embodiment of the present invention, the locking processing on the data object set and the inserting the second data object into the data object set successfully subjected to the locking processing include:
locking the data object set, and judging whether the locking is successful;
and if the locking processing fails, placing the second data object in the candidate queue, so that the candidate queue performs locking processing on the data object set again until the locking processing is successful.
Specifically, when the locking fails, the target data object to be inserted into the data object set is placed in the candidate queue, so that the locking processing is performed subsequently.
Further, according to the embodiment of the present invention, if the locking process is successful, the method further includes:
judging whether a data object corresponding to the user identifier exists in the data object set which is successfully locked again according to the user identifier;
if the traffic value exists, taking a data object corresponding to the user identifier in the data object set as a target data object, and writing the traffic value counted in the second data object into the target data object;
and if not, inserting the second data object into the data object set.
In specific implementation, when the locking process may be performed last time, corresponding data objects are inserted for the same user identifier, and in order to ensure that only the uniquely corresponding data object exists for the same user identifier in the data object set, it is necessary to query and determine whether the data object corresponding to the user identifier exists in the data object set again. If the data object exists, taking the data object corresponding to the user identifier in the data object set as a target data object corresponding to the user identifier, namely updating the target data object and acquiring the address of the target data object; and if the flow value does not exist, inserting a second data object which is newly created and completes the flow value statistics in the current flow transmission process into the data object set, and updating the data object set.
Specifically, according to the embodiment of the present invention, the statistical operation on the traffic value transmitted corresponding to the traffic transmission request is performed in an atomic operation manner.
Atomic operations refer to operations that are not interrupted by a thread scheduling mechanism, and once started, run to the end without switching to another thread in the middle. Counting in an atomic operation mode: when multiple threads add operations to the same counter (the traffic values counted by multiple traffic transmission requests initiated by the same client are superimposed on the original statistical value of the same data object), if the locking is not performed, the counter value (the superimposed total statistical value) is inaccurate, and if the locking operation is performed to the same counter value, multiple threads compete for the same lock, so that the calculation efficiency is reduced. By using the atomic operation, an operation lock is not needed, the calculation operation is completed by the compiler and the hardware, the calculation performance is improved, and the realization of the logic is simpler.
According to the embodiment of the present invention, in a specific implementation, the same client may initiate multiple traffic transmission requests at the same time, that is, multiple statistical units all obtain data object addresses corresponding to the same user identifier from a data object set, and write corresponding traffic values into the corresponding addresses in the traffic transmission process of each statistical unit. Through atomic operation, multiple writing of the same data object is realized, and errors in writing (summarizing, and overlaying of newly written data to the original statistical flow value) of multiple statistical values are avoided.
Step S206, adjusting the flow quota corresponding to each data object according to the flow quota policy and the flow value of each data object in the data object set.
The proxy server establishes a flow quota policy according to network bandwidth, data of a network terminal (client) initiating access and the like, adjusts a flow quota (residual flow quota) corresponding to each data object in a data object set by combining flow values (a total flow value updated in real time and including a flow value generated in each flow transmission process) corresponding to each data object, and executes corresponding operations (such as warning, current limiting and the like) according to the flow quota of each data object.
According to the technical scheme of the embodiment of the invention, one or more flow transmission requests are received, and the user identification is determined according to the request information in the flow transmission request aiming at each flow transmission request; the flow transmission request comprises an access request sent by a client in the current flow transmission request and a response request returned by a target server; searching from the data object set according to the user identification to determine a first data object, and acquiring a corresponding address of the first data object in the data object set; the data object is used for indicating the corresponding relation between the user identification and the flow value correspondingly transmitted by the user identification; carrying out statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object, and writing the statistical operation result into the address of the first data object corresponding to the data object set; the technical means of adjusting the flow quota corresponding to each data object according to the flow quota policy and the flow value of each data object in the data object set overcome the technical problems of dependence on the performance of an external database, low adjustment efficiency and low accuracy of the adjusted flow quota in the existing method, and further achieve the technical effects of improving the flow statistical efficiency, improving the efficiency of adjusting the flow quota and ensuring the accuracy of the adjusted flow quota.
Fig. 3 is a schematic diagram of main modules of an apparatus for adjusting a traffic quota, according to an embodiment of the present invention; as shown in fig. 3, an apparatus 300 for adjusting a traffic quota according to an embodiment of the present invention mainly includes:
a receiving module 301, configured to receive one or more traffic transmission requests, and determine, for each traffic transmission request, a user identifier according to request information in the traffic transmission request; the traffic transmission request comprises an access request sent by a client in the current traffic transmission request and a response request returned by the target server.
Specifically, according to the embodiment of the present invention, for the multiple traffic transmission requests, the multiple traffic transmission requests may be sent by one network terminal, or may be sent by multiple network terminals, and one network terminal (e.g., a client) may initiate multiple traffic transmission requests at the same time.
Further, according to the embodiment of the present invention, an interaction between the client and the target server is involved in one traffic transmission process, and the traffic value in the subsequent determination of the current traffic transmission process is also referred to as a traffic value generated in one interaction process (request and response).
Illustratively, the request information includes information such as a user number, an IP address, and a port number, and the user identifier is determined according to the request information, which is helpful for subsequently determining a data object corresponding to the user identifier, so as to count a traffic value in a traffic transmission process.
The first data object determining module 302 is configured to search from the data object set according to the user identifier to determine a first data object, and obtain an address of the first data object in the data object set; the data object is used for indicating the corresponding relation between the user identification and the flow value correspondingly transmitted by the user identification.
Through the setting, the first data object is determined from the data object set according to the unique user identifier corresponding to the flow transmission request, the flow value in the flow transmission request is counted on the basis of the flow value counted by the data object, the total flow value corresponding to the user in the process of multiple flow transmission requests is determined conveniently, and the flow quota is adjusted conveniently subsequently. On the other hand, the address of the first data object corresponding to the data object set is obtained, which is helpful for directly writing the traffic value counted in the current traffic transmission process into the address, namely directly writing the traffic value into the first data object corresponding to the user identifier in the data object set, so that the real-time counting of the traffic value is realized, the counting efficiency of the traffic value is improved, and the adjustment efficiency of the traffic quota is further improved.
Further, according to the embodiment of the present invention, the apparatus 300 for adjusting a traffic quota further includes a second data object determining module, where if it is determined that there is no first data object corresponding to the user identifier in the process of searching the data object set; a second data object creation module to:
creating a second data object according to the user identification;
and performing statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the second data object, and writing the statistical operation result into the second data object.
In the actual implementation process, after the user identifier is determined, firstly, whether a first data object corresponding to the user identifier exists in a data object set is inquired and judged, and if the first data object exists, a corresponding address of the first data object in the data object set is obtained; if not, the first data object corresponding to the user identifier is not existed in the data object set, that is, the client corresponding to the user identifier has not initiated the request for the excessive flow transmission and has not generated the excessive flow value, at this time, the second data object is reconstructed according to the user identifier and is used as the data object for the flow value statistics in the current transmission process. Through the arrangement, even if the client initiating the flow transmission request does not have a corresponding data object in the data object set, the flow value statistics can be carried out by establishing the data object, and then the data object set is updated according to the second data object, so that the statistical efficiency and the statistical accuracy of the flow value are ensured, and meanwhile, even if a plurality of flow transmission requests initiated by the client corresponding to the user identification are received, the flow value corresponding to each flow transmission request can be simultaneously counted, the iterative statistics is carried out on the total flow value, the statistical efficiency is improved, and the statistical error is avoided.
The counting module 303 is configured to perform a counting operation on a traffic value transmitted by the target data object in the current traffic transmission process, and write a result of the counting operation into a corresponding address of the target data object in the data object set.
Specifically, according to the embodiment of the present invention, after the step of writing the result of the statistical operation into the second data object, the statistical module 303 is further configured to:
judging whether a data object corresponding to the user identifier exists in the data object set or not;
if so, acquiring an address corresponding to the data object corresponding to the user identifier in the data object set, and writing the flow value counted in the second data object into the address;
and if not, locking the data object set, and inserting the second data object into the data object set successfully subjected to locking.
In a specific embodiment, in the process of constructing a new data object (i.e., a second data object) according to a user identifier, a data object corresponding to the user identifier may have been inserted into a data object set by other statistical units, and in order to avoid that multiple data objects exist in the data object set for the same user identifier, before inserting a newly constructed target data object into the data object set, it is necessary to determine again whether a data object corresponding to the user identifier exists in the data object set.
According to another specific implementation manner of the embodiment of the present invention, since the same client may initiate multiple traffic transmission requests simultaneously, at this time, second data objects are respectively constructed for the user identifier corresponding to each traffic transmission request, that is, before inserting a data object set, multiple second data objects may have been constructed for the same user identifier, if a second data object is directly inserted into the data object set, after the client initiates a traffic transmission request again, multiple data objects corresponding to the user identifier may be queried in the data object set, so that complexity of determining a target data object is increased, a difficulty coefficient is further added to summarization of a total traffic value corresponding to the user identifier, and more statistical time of the traffic value is consumed. Therefore, when the newly constructed second data object is inserted into the data object set, the data object set needs to be locked, and after the locking is successful, the newly constructed second data object is inserted into the data object set.
Through the setting, before the flow value statistics is executed, the data object corresponding to the user identifier is effectively ensured to exist, and the flow value generated by the client corresponding to the user identifier in the flow transmission process is counted (if the data set has the first data correspondence, the flow value counted in the current flow transmission process is directly summarized to the original flow value counted according to the address of the first data object), so that the real-time performance of the flow statistics is ensured, and the adjustment efficiency of the flow quota is improved.
Illustratively, according to an embodiment of the present invention, the statistic module 303 is further configured to:
locking the data object set, and judging whether the locking is successful;
and if the locking processing fails, placing the second data object in the candidate queue, so that the candidate queue performs locking processing on the data object set again until the locking processing is successful.
Specifically, when the locking fails, the target data object to be inserted into the data object set is placed in the candidate queue, so that the locking processing is performed subsequently.
Further, according to an embodiment of the present invention, if the locking process is successful, the statistical module 303 is further configured to:
judging whether a data object corresponding to the user identifier exists in the data object set which is successfully locked again according to the user identifier;
if the traffic value exists, taking a data object corresponding to the user identifier in the data object set as a target data object, and writing the traffic value counted in the second data object into the target data object;
and if not, inserting the second data object into the data object set.
In specific implementation, when the locking process may be performed last time, corresponding data objects are inserted for the same user identifier, and in order to ensure that only the uniquely corresponding data object exists for the same user identifier in the data object set, it is necessary to query and determine whether the data object corresponding to the user identifier exists in the data object set again. If the data object exists, taking the data object corresponding to the user identifier in the data object set as a target data object corresponding to the user identifier, namely updating the target data object and acquiring the address of the target data object; and if the flow value does not exist, inserting a second data object which is newly created and completes the flow value statistics in the current flow transmission process into the data object set, and updating the data object set.
Specifically, according to an embodiment of the present invention, the statistical module 303 is further configured to:
and counting the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object in an atomic operation mode.
Atomic operations refer to operations that are not interrupted by a thread scheduling mechanism, and once started, run to the end without switching to another thread in the middle. Counting in an atomic operation mode: when multiple threads add operations to the same counter (the traffic values counted by multiple traffic transmission requests initiated by the same client are superimposed on the original statistical value of the same data object), if the locking is not performed, the counter value (the superimposed total statistical value) is inaccurate, and if the locking operation is performed to the same counter value, multiple threads compete for the same lock, so that the calculation efficiency is reduced. By using the atomic operation, an operation lock is not needed, the calculation operation is completed by the compiler and the hardware, the calculation performance is improved, and the realization of the logic is simpler.
According to the embodiment of the present invention, in a specific implementation, the same client may initiate multiple traffic transmission requests at the same time, that is, multiple statistical units all obtain data object addresses corresponding to the same user identifier from a data object set, and write corresponding traffic values into the corresponding addresses in the traffic transmission process of each statistical unit. Through atomic operation, multiple writing of the same data object is realized, and errors in writing (summarizing, and overlaying of newly written data to the original statistical flow value) of multiple statistical values are avoided.
The adjusting module 304 is configured to adjust a traffic quota corresponding to each data object according to the traffic quota policy and the traffic value of each data object in the data object set.
The proxy server establishes a flow quota policy according to network bandwidth, data of a network terminal (client) initiating access and the like, adjusts a flow quota (residual flow quota) corresponding to each data object in a data object set by combining flow values (a total flow value updated in real time and including a flow value generated in each flow transmission process) corresponding to each data object, and executes corresponding operations (such as warning, current limiting and the like) according to the flow quota of each data object.
According to the technical scheme of the embodiment of the invention, one or more flow transmission requests are received, and the user identification is determined according to the request information in the flow transmission request aiming at each flow transmission request; the flow transmission request comprises an access request sent by a client in the current flow transmission request and a response request returned by a target server; searching from the data object set according to the user identification to determine a first data object, and acquiring a corresponding address of the first data object in the data object set; the data object is used for indicating the corresponding relation between the user identification and the flow value correspondingly transmitted by the user identification; carrying out statistical operation on the traffic value transmitted corresponding to the traffic transmission request corresponding to the first data object, and writing the statistical operation result into the address of the first data object corresponding to the data object set; the technical means of adjusting the flow quota corresponding to each data object according to the flow quota policy and the flow value of each data object in the data object set overcome the technical problems of dependence on the performance of an external database, low adjustment efficiency and low accuracy of the adjusted flow quota in the existing method, and further achieve the technical effects of improving the flow statistical efficiency, improving the efficiency of adjusting the flow quota and ensuring the accuracy of the adjusted flow quota.
