Ask quantity to exceed the manageable maximum trading volume of system) time still can be properly functioning, be generally required for design overload and protect
Protective function, i.e. flow-control.
The common methods carrying out flow-control is: each circuit for every station server all configures a single flow control
Parameter processed, such as circuit ceiling, this flow control parameter is only used for judging whether the flow of the circuit corresponding to this parameter surpasses
Cross this restriction, if it does, then take corresponding flow control policy to carry out current limliting, to guarantee the properly functioning of system.

The arm's length dealing of other external systems.At this moment, it is necessary to by the stream that flow-control is certain to each external system integral dispensing
Amount limit, it is ensured that the transaction of each external system all can normal process.
In current practice, if needing to realize the overall flow-control to certain external system, can only will distribute to this
The bulk flow of external system is fixedly assigned to all affiliated circuits, as each bar circuit is divided equally, part by certain distribution method
Circuit distributes big flow, part circuit distribution low discharge etc..
But when distributing to multiple circuit according to firm discharge limit, the flow that actually occurs of some circuit exceeds well over as its point
The firm discharge limit joined so that this circuit processing pressure is relatively big, and the flow that actually occurs of some circuit is much smaller than as its point
The firm discharge limit joined.As certain circuit occurs in that suddenly big flow in the case of dividing equally.And for example part circuit distribute big flow,
In the case of part circuit distribution low discharge, the circuit distributing big flow but occurs in that low discharge, and the circuit of distribution low discharge is but
Occur in that big flow.Therefore, by fixed allocation stream quantitative limitation, it is impossible to carry out Real-time and Dynamic adjustment for different circuits so that
Line resource can not be fully used, and causes the waste of line resource.Therefore, the assignment of traffic side of existing distributed system
Method, needs to be optimized.
To sum up, prior art carries out according to firm discharge limit the circuit assignment of traffic of distributed system, exists each
The transaction flow of circuit cannot dynamically adjust, and causes the wasting skill of line resource of some circuit over loadings, some circuits
Art problem.

In order to realize each circuit in packet is carried out flow dynamics control, the embodiment of the present invention 3 layers of flow-control of design
Parameter, the flow control parameter of each packet includes 3 layers of flow control parameter, includes following configuration for arbitrary packet: arbitrary
Packet configuration one is grouped the highest current limliting, and the highest current limliting of packet of arbitrary packet is definite value, and the highest limit of packet of different grouping
Stream configuration is identical or different；One the highest current limliting of circuit of arbitrary line configuring and circuit dynamic current limiting, the circuit of arbitrary circuit
The highest current limliting is definite value, and the highest current limliting of circuit of each bar circuit in same packet is identical or different；The circuit of arbitrary circuit moves
State current limliting is adjustable, and the circuit dynamic current limiting of arbitrary circuit is less than or equal to the highest current limliting of circuit of this circuit.
Current limliting the highest for circuit, refers to that the maximum limit flow valuve that single line allows, the i.e. the highest current limliting of circuit are less than thing
The flow that in reason, circuit maximum can carry, the visual practical situation of occurrence determines, this value is fixed, will not be along with packet traffic control
Dynamically adjust and adjust.
For circuit dynamic current limiting, refer to that the cut-off current that single line allows temporarily, circuit dynamic current limiting can be modified,
Modified values is controlled by NetStream Data Analyzer and flow regulator, the highest less than the highest current limliting of circuit.Initial value can be defaulted as
The highest current limliting of circuit.
For being grouped the highest current limliting, referring to the maximum limit flow valuve that single packet allows, this value is fixed, will not be along with stream of packets
What amount controlled dynamically adjusts and adjusts, and value determines depending on practical situation.
The configuration structure of 3 layers of flow control parameter sees Fig. 3.As it is shown on figure 3, the flow control parameter configuration of every circuit
Information includes the highest current limliting of circuit of circuit, circuit dynamic current limiting, packet ID, circuit ID.The flow-control of each logic groups
Parameter configuration includes the corresponding relation being grouped the highest current limliting and packet ID.Circuit ID is used for distinguishing different circuit, such as circuit 1
The identification code that circuit ID is circuit 1, packet ID is for distinguishing different logic groups, and such as the numbering of packet, circuit 1 place is divided
Group is packet 1, then the packet ID of circuit 1 is the numbering of packet 1.
Packet traffic in each packet controls in parameter configuration, the highest current limliting of packet of each packet and this packet
Packet ID there is corresponding relation, therefore, NetStream Data Analyzer can packet traffic based on each packet control parameter configuration letter
Breath, in conjunction with current transaction flow and the highest current limliting of packet of configuration of each packet, determines which packet needs to carry out flow tune
Joint, which packet is made without Flow-rate adjustment.In the flow control parameter configuration information of every circuit, the line of every circuit
There is corresponding relation in the packet ID of the highest current limliting in road and circuit dynamic current limiting and the circuit ID of this circuit, the packet of this circuit place,
Therefore when NetStream Data Analyzer determines the packet needing to carry out Flow-rate adjustment, can be according to the flow control of the circuit belonging to this packet
Parameter configuration processed, redefines out the dynamic current limiting parameter needing to carry out the circuit of Flow-rate adjustment.NetStream Data Analyzer determines
After going out the adjusted value needing to carry out the dynamic current limiting of the circuit of Flow-rate adjustment, by dynamic current limiting adjusted value and the circuit of circuit
ID is sent to the flow regulator that this circuit is corresponding.
Above-mentioned logic groups based on the part or all of circuit in distributed transaction system, NetStream Data Analyzer and flow are adjusted
The deployment of joint device, and the configuration of the flow control parameter of each logic groups and the interior circuit of packet, can realize distributed system
The flow to each circuit that is in operation carries out Real-time and Dynamic regulation and control.During whole circuit flow-control, only circuit is moved
This parameter of state current limliting is modified.
The flow control methods that the embodiment of the present invention provides is performed by NetStream Data Analyzer and flow regulator.NetStream Data Analyzer
By the transaction of bar circuit each in certain time in transaction data base is added up, the packet of combined circuit, calculate current point
The loading condition of group also judges whether to need to carry out flow-control, if needing to control, then the modified values of flow-control is notified
Flow regulator comes into force.NetStream Data Analyzer and flow regulator carry out the Real-time and Dynamic of flow and adjust the circuit in packet
Whole, mainly include two kinds of situations.
A kind of situation is: NetStream Data Analyzer timing (setting of visual practical situation of concrete cycle) accesses database server,
Add up each current transaction flow of bar circuit, calculate the total flow of currently concluding the business of each packet further according to rule of classification, it may be judged whether be super
Cross the highest current limliting of packet of this grouping and setting, if it does, the new circuit continuing to calculate the interior each circuit of packet dynamically limits
Stream, and notify that flow regulator is adjusted in the way of Flow-rate adjustment instruction.Flow regulator receives NetStream Data Analyzer transmission
Flow-rate adjustment instruction, according to new circuit dynamic current limiting, notify and revise the old circuit dynamic current limiting of corresponding line, generally
Circuit dynamic current limiting information is stored in a storage file of transaction processing server, can be replaced by new circuit dynamic current limiting
Fall old circuit dynamic current limiting, make new circuit dynamic current limiting come into force, finally realize the dynamic control of flow.
Another kind of situation is: NetStream Data Analyzer is if it find that current group flow is not less than being grouped the highest current limliting, but packet
When interior certain circuit has reached the circuit dynamic current limiting of this circuit, need to tune up the circuit dynamic current limiting of this circuit, in order to
Make full use of line load, continue to calculate the new circuit dynamic current limiting of the interior each circuit of packet, and instruct with Flow-rate adjustment
Mode notify that flow regulator is adjusted.This is because certain circuit reaches when reaching circuit dynamic current limiting of this circuit,
There may be the outside actual request flow situation more than currently practical flow of circuit, if the transaction total flow of packet is less than
It is grouped the highest current limliting, then the dynamic line limit of this circuit can be tuned up, in order to promote the utilization rate of line resource.Flow is adjusted
Joint device receives the Flow-rate adjustment instruction of NetStream Data Analyzer transmission, according to new circuit dynamic current limiting, notifies and revises corresponding line
Old circuit dynamic current limiting, finally realize the dynamic control of flow.
In the embodiment of the present invention, NetStream Data Analyzer only disposes one can realize flow control function, it is possible to dispose multiple.

Easily flow is controlled.
In a kind of optional embodiment, needing the circuit carrying out flow adjustment is the part circuit in being grouped, and step 502 is wrapped
Include: according to the proportionate relationship between the current transaction flow of part or all of circuit, determine the line that part or all of circuit is corresponding
The adjusted value of road dynamic current limiting, to reduce the transaction flow of part or all of circuit.
Such as, in distributed system architecture as shown in Figure 2, configure the circuit of every circuit of every transaction processing server
The highest current limliting is 300, and initial plant dynamic current limiting is also configured as 300, and the highest current limliting of packet of each packet is 400, circuit 1,
Circuit 3, circuit 5 is packet 1, and circuit 1, circuit 3, the current transaction flow of circuit 5 is respectively as follows: 200,150,80.Because of packet 1
Transaction total flow is more than 400, it is therefore desirable to the circuit in this packet carries out Flow-rate adjustment, specifically can select circuit 1, circuit
3 for need the circuit carrying out flow adjustment, the ratio between circuit 1 and the current transaction flow of circuit 3 be 4:3, if with packet
The highest current limliting 400 is radix, occupies ratio (250:200) equal proportion in the current transaction flow of circuit 1 and circuit 3 in packet 1
Adjust, then in packet 1, the circuit dynamic current limiting of circuit 1 will be adjusted to The circuit dynamic current limiting of circuit 3 will
It is adjusted toSo after a period of time, the transaction flow of circuit 1 and circuit 3 can decline, and finally makes packet
Within the transaction total flow of 1 drops to 400.
In a kind of optional embodiment, needing the circuit carrying out flow adjustment is the whole circuits in being grouped, and step 502 is wrapped
Include: according to the proportionate relationship between the current transaction flow of whole circuits, determine the circuit dynamic current limiting that each circuit is corresponding
Adjusted value, to reduce the transaction flow of part or all of circuit.
Such as, in distributed system architecture as shown in Figure 2, configure the circuit of every circuit of every transaction processing server
The highest current limliting is 300, and initial plant dynamic current limiting is also configured as 300, and the highest current limliting of packet of each packet is 400, wherein, often
Platform transaction processing server two lines Lu Weiyi is grouped, (unit multi-line packet mode the most as shown in Figure 2, circuit 1 and line
Road 2 is packet 1, and circuit 3 and circuit 4 are packet 2, and circuit 5 and circuit 6 are packet 3).
Assuming in current line, the current transaction flow of each circuit is as follows:
Circuit 1:250
Circuit 2:200
Circuit 3:100
Circuit 4:200
Circuit 5:50
Circuit 6:300
Owing to the maximum flow of single line is limited by circuit self Current limited Control, namely external flow even more than
300, limited by circuit self maximum flow, actually enter the flow of system the highest by also only 300, therefore NetStream Data Analyzer only needs place
The flow-control of reason packet.
NetStream Data Analyzer performs above-mentioned steps 402, obtains the total flow of currently concluding the business of each packet, it may be assumed that packet 1:450,
Packet 2:300, is grouped 3:350.
NetStream Data Analyzer performs above-mentioned steps 403, passes through and is grouped the highest current limliting 400 and compare, determines the flow of packet 1
450 have exceeded 400 set, and packet 1 is the packet needing to carry out Flow-rate adjustment, and is grouped 2 and is grouped 3 all not less than being grouped
High current limliting, it is not necessary to adjust.NetStream Data Analyzer occupies ratio in the current transaction flow of each circuit in packet 1, will be grouped circuit 1 in 1
Carry out equal proportion with the circuit dynamic current limiting of circuit 2 to turn down, or the circuit by circuit 1 maximum for transaction flow current in packet
Dynamic current limiting is individually turned down.
Such as, NetStream Data Analyzer is with packet the highest current limliting 400 as radix, by circuit 1 in packet 1 and the current friendship of circuit 2
Easily flow occupies the adjustment of ratio (250:200) equal proportion, then in packet 1, the circuit dynamic current limiting of circuit 1 will be adjusted toThe circuit dynamic current limiting of circuit 2 will be adjusted to After certain time, circuit 1
The transaction flow of transaction flow and circuit 2 can decline, within making the transaction total flow of packet 1 drop to 400.As shown in Figure 2
In the framework of distributed transaction system, circuit 1 and circuit 2 all access transaction processing server 1, and flow regulator 1 controls circuit 1
With the Flow-rate adjustment of circuit 2, the flow regulator 1 on such NetStream Data Analyzer notice transaction processing server 1 is by circuit 1 and line
The first original circuit dynamic current limiting (such as initial value 300) on road 2 is respectively modified as 222 and 178.After certain time, the transaction flow of circuit 1
Amount and the transaction flow of circuit 2 can decline, and the transaction flow such as circuit 1 is dropped to 100 by 250, and the transaction flow of circuit 2 by
200 drop to 178.
After the transaction flow of circuit 1 and the circuit dynamic current limiting of circuit 2 are turned down, the transaction flow of circuit 1 and line
The transaction flow on road 2 can decline, this is because: for circuit 1, after circuit dynamic current limiting is adjusted to 22, circuit 1 is interim
The cut-off current allowed is 222, and transaction processing server 1 can be according to the real trade flow of circuit 1 and circuit dynamic current limiting 222
Between difference, control the load of this circuit, such as, when detecting that relatively circuit 1 was in certain period of time, such as the friendship of 2 minutes
Easily flow is always close to the circuit dynamic current limiting 222 of this circuit, and outside this circuit of access system of notice is in busy state, it is proposed that
Outside access system selects to access other not busy circuits, and so, outside access system the most no longer accesses this circuit, one section
After time, the transaction flow of this circuit 1 of fully loaded will drop to circuit dynamic current limiting less than 222.The transaction flow of circuit 2
The reason that amount can decline is in like manner.
In a kind of optional embodiment, the line needing the circuit carrying out flow adjustment to be the interior current transaction flow maximum of packet
Road, step 502 includes: according to current total transaction flow of the current transaction flow of the maximum circuit of current transaction flow with packet
Ratio, determine the adjusted value of the circuit dynamic current limiting that the maximum circuit of current transaction flow is corresponding, to reduce current transaction flow
The transaction flow of maximum circuit.
Such as, still the circuit 1 of the packet 1 in the example above and the circuit dynamic current limiting of circuit 2 are adjusted, circuit
The current transaction flow of 1 is maximum (250), when adjusting, with packet the highest current limliting 400 as radix, or with the highest current limliting of circuit
For radix, will individually the circuit dynamic current limiting (being defaulted as 300) of circuit 1 be adjusted toOr, adjust
For
These are only the current transaction flow of the circuit maximum according to current transaction flow and current total transaction flow of packet
The ratio of amount determines the citing of the adjusted value of the circuit dynamic current limiting that the circuit of current transaction flow maximum is corresponding, it is also possible to according to it
His adjustable strategies, determines the adjusted value of the circuit dynamic current limiting that the maximum circuit of current transaction flow is corresponding.
