For the application's above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
Prior art has been solidificated in business demand in flow control methods, thereby the specific aim of method is more intense, causes each business demand, all needs the flow control methods of a kind of uniqueness that Pei Ge is corresponding with it, and flow control methods durability is lower.
The application provides a kind of flow control methods, and business demand is independent, can call different Flow Control plug-in units for different first-class control main bodys, thereby make the flow control methods described in the application be applicable to various business, and durability is very high.
With reference to Fig. 1, provided a kind of flow control methods flow chart described in the embodiment of the present application.
When access services device, need to control flow, therefore can transmitted traffic control request.Correspondence can receive flow control request, and wherein, described flow control request comprises first-class control main body.
Flow Control main body refers to the main body of carrying out flow control, with concrete traffic aided.For example, in banking, described Flow Control main body can be the POS machine paying; In social network-i i-platform, described Flow Control main body can be the user of this platform, or logins the IP address of this platform.
Wherein, described POS(Point Of Sale) machine is point-of-sale terminal, it is a kind of multi-functional terminal end, it is arranged on to the franchised business of credit card and accepts in site and be unified into network with computer, just can realize electronic funds automatic account transfer, it has the functions such as the consumption of support, pre-authorization, inquiry into balance and account transfer, uses safety, quick, reliable.The machine of POS described in the application can be virtual POS machine.
Wherein, there is not the body of physics POS machine in described virtual POS machine, but comprise the various data that POS machine possesses itself, as POS terminal number, and trade company number, key etc.When third party pays Yu bank of company docking and realizes POS and receive single business, bank is considered as Yi Ge trade company by third party's payment company conventionally, distribute a lot of terminal datas (being virtual POS machine) to this trade company, third party pays company and just can carry out with the virtual POS machine that bank distributes the single operation of POS receipts like this.
IP is Internet Protocol, and Internet protocol is computer network and interconnects the agreement that communicates and design.
Above-mentionedly in flow control request, get after first-class control main body, that can obtain described first-class control main body joins Ge information, in actual treatment, described in can obtaining, joins Ge information from buffer memory, can from database, obtain described Pei Ge information, the application does not limit this yet.
Wherein, described Pei Ge information comprises the requesting threshold of described first-class control main body, certainly, can also comprise the data such as classification of first-class control main body in described Pei Ge information, and the application does not limit this.
Because different business exists different business demands, prior art has been solidificated in business demand in flow control methods, but in actual treatment, judgement for visit capacity is comparison general character, and be comparison individual character for the judgement of business demand, this has just caused existing flow control methods specific aim more intense, and durability is lower.
Therefore the application is when carrying out flow control, independent by the business demand that compares individual character, and the judgement of comparing the visit capacity of general character is integrated.In specific implementation, can pass through She Ge card i/f, for all kinds of business demands, by described card i/f and concrete traffic aided connection, wherein, described business plug-in unit is used for preserving business demand strategy, and for example, whether POS machine is not frozen.Business demand She Ge is judged in plug-in unit, therefore, when needing business to participate in flow control, call corresponding business plug-in unit and carry out business demand judgement.
Therefore, can call business plug-in unit corresponding to described first-class control main body by card i/f, judge whether described first-class control main body meets business demand.For example, described first-class control main body is POS-A1, and business plug-in unit corresponding to described first-class control main body is financial business plug-in unit, can call described financial business plug-in unit by described card i/f, judge whether POS-A1 meets business demand, whether not frozen etc. such as POS-A1.
If so, meet all kinds of business demands, perform step 14; If not, do not meet certain class business demand, perform step 16.
If meet all kinds of business demands, can further compare the determining step of the visit capacity of general character, can detect first-class control main body and whether reach requesting threshold, if described first-class control main body has reached requesting threshold, described first-class control main body can not conduct interviews; If described first-class control main body does not reach requesting threshold, described first-class control main body can conduct interviews.In concrete enforcement, can judge whether the current accessed amount of described first-class control main body is less than described requesting threshold.
If so, perform step 15; If not, perform step 16.
For example, POS-A1 is not frozen, and the requesting threshold of POS-A1 is 5.If the current accessed amount of POS-A1 is 3<5, follow-up execution step 15, if the current accessed amount of POS-A1 is 5=5, follow-up execution step 16.
Meeting under the prerequisite of business demand, if described first-class control main body does not reach requesting threshold, when the current accessed amount of described first-class control main body is less than described requesting threshold, described first-class control main body can conduct interviews, and therefore current accessed amount can be added and return in the lump successfully sign.
In upper example, the current accessed amount of POS-A1 is 3, the current accessed amount of POS-A1 can be added to one, and current accessed amount is 3+1=4, then returns to successfully sign, and POS-A1 can continue follow-up access, carries out corresponding business etc.
When not meeting business demand, described first-class control main body can not conduct interviews, and returns to unsuccessfully sign.Or described first-class control main body has reached requesting threshold,, when the current accessed amount of described first-class control main body is more than or equal to described requesting threshold, described first-class control main body can not conduct interviews, and returns to unsuccessfully sign.
As above in example, POS-A1 is not frozen, and the current accessed amount of POS-A1 is 5, now will return to unsuccessfully sign, and POS-A1 can not continue candidate's access.And for example, POS-A1 is frozen, now will return to equally unsuccessfully sign, and POS-A1 can not continue candidate's access.
In sum, in flow control methods, different business demand corresponding to business, and meeting under the prerequisite of business demand, control method for visit capacity is basically identical, therefore the flow control methods described in the application, independent by unique business demand, and consistent visit capacity control method is integrated.Therefore after receiving flow control request, first obtain first-class control main body Pei Ge information, then for all kinds of business demands, by card i/f, call business plug-in unit corresponding to described first-class control main body, by described business plug-in unit, judge whether described first-class control main body meets such business demand, and then the judgement of the amount of conducting interviews.Therefore, the application can, for different first-class control main bodys, call corresponding with it all kinds of Flow Control plug-in unit judgement business demands, and adopt consistent visit capacity control method, thereby make the flow control methods described in the application be applicable to various business, durability is very high.
Preferably, in described flow control request, also comprise Flow Control strategy,
Described current accessed amount also comprises after being more than or equal to described requesting threshold:
Flow Control strategy in flow control request is judged; When Flow Control strategy is refusal, return to unsuccessfully sign; When Flow Control strategy is when switching, what be switched to the second Flow Control main body and obtain described the second Flow Control main body joins Ge information.
As above in example, POS-A1 is not frozen, and the current accessed amount of POS-A1 is 5, can also detect the Flow Control strategy in flow control request, if Flow Control strategy is refusal, now will return to unsuccessfully sign, and POS-A1 can not continue candidate's access.If Flow Control strategy, for switching, is switched to the second Flow Control main body as POS-A2, and obtain described the second Flow Control main body join Ge information.Then can re-execute above-mentioned steps 13, described the second Flow Control main body is carried out to flow control.
Preferably, in described Pei Ge information, also comprise the classification of first-class control main body, in described flow control request, also comprise switching threshold.
Described in the application, join the classification that also comprises first-class control main body in Ge information, under described classification, comprise a plurality of Flow Control main bodys, as first-class control main body, the second Flow Control main body etc.If the classification of POS-A1 is user A, user A also has POS-A2 and POS-A3.
With reference to Fig. 2, provided described in the application's preferred embodiment main body switching flow figure in a kind of flow switch method.
The described step that is switched to the second Flow Control main body comprises:
If Flow Control strategy is carried out in above-mentioned judgement, follow-uply join Ge information in can query caching, then search under the classification of described first-class control main body whether have the second Flow Control main body.
If so, there is described the second Flow Control main body, perform step 202; If not, there is not described the second Flow Control main body, perform step 204.
For example, the classification of POS-A1 is user A, and user A also has POS-A2 and POS-A3.
Wherein, described switching times is for same flow control request, from receiving a certain flow control request, till return to successfully sign or end mark for this flow control request, during the number of times of the Flow Control main body switched of described flow control request.As above in example, user A comprises that 3 Flow Control main bodys are respectively POS-A1, POS-A2 and POS-A3, if initial first-class control main body is POS-A1, when being switched to POS-A2 by POS-A1, switching times is 1, when being switched to POS-A3 by POS-A2 again, switching times is 2, by that analogy, every switching 1 time, switching times+1.
Therefore, be if so, that switching times is less than switching threshold, perform step 203; If not, switching times is not less than switching threshold, performs step 204.
Whether the switching times that detects described classification is less than switching threshold, and for example, switching threshold is 10, if the switching times of user A be 3<10, perform step 203; If the switching times of user A is 10=10, perform step 204.
If switching times is less than switching threshold, can chooses at random the second Flow Control main body under the classification of a described first-class control main body and carry out and switch.
For example, the switching times of user A is 3< switching threshold 10, can from POS-A2 and POS-A3, as the second Flow Control main body, then carry out and switch by an optional POS machine, use described second control volume to carry out business, and described second control volume is carried out to flow control.
If there is not described the second Flow Control main body, or, there is described the second Flow Control main body but switching times is not less than switching threshold, handoff failure, returns to unsuccessfully sign.
In sum, the application, when the current accessed amount of first-class control main body is more than or equal to described requesting threshold, follow-uply can carry out Flow Control strategy.According to the classification of first-class control main body, search the second Flow Control main body under described classification, be then switched to the second Flow Control main body, and obtain described the second Flow Control main body join Ge information, re-start flow control.The application's flow control methods is more flexible, and Flow Control strategy is various.

Whether step 301, is meeting under the prerequisite of all kinds of business demands, detect current accessed amount and exist;
Meeting under the prerequisite of business demand, detecting current accessed amount and whether exist, in query caching, whether having current accessed amount, if there is not described current accessed amount, performing step 302; If there is described current accessed amount, perform step 303.
Step 302 is 0 by current accessed Liang She Ge;
If there is not described current accessed amount, for the first time described first-class control main body is carried out to flow control, so can be 0 by current accessed Liang She Ge, then follow-up execution step 305.
Step 303 is obtained current accessed amount from buffer memory;
When there being described current accessed amount, can from buffer memory, obtain current accessed amount.
If so, be that current accessed amount is less than described requesting threshold, perform step 305; If not, perform step 307.
When current accessed amount is less than described requesting threshold, or, after current accessed Liang She Ge is 0, current accessed amount can be added to one, and be updated in buffer memory;
In sum, the application will join Ge information and current accessed amount is kept in buffer memory, can reduce the call operation to database, thereby reduces the burden in flow control, database being caused.
With reference to Fig. 4, provided described in the application's preferred embodiment flow in a kind of flow control methods and discharged flow chart.
