Detailed description of the invention
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is carried out clearly and completely
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative labor
The every other embodiment obtained under dynamic premise, broadly falls into the scope of protection of the invention.
Embodiments providing a kind of flow control methods, the method can apply to distributed apparatus
Or in centralized device, for distributed apparatus, retransmission unit is the veneer in distributed apparatus, such as Fig. 1
Shown in, the structural representation of a kind of distributed apparatus provided for the embodiment of the present invention, in distributed apparatus
Each veneer on be both provided with one or more local token set, one of them veneer sets simultaneously
Being equipped with master control token set, for centralized device, retransmission unit is to arrange on the veneer of centralized device
Chip, the veneer in centralized device is provided with one or more chip, each chip is provided with
One or more local token set, one of them chip is provided with master control token set simultaneously,
In embodiments of the invention, the token that all local token set are obtained is distributed by master control token set.
Below, in conjunction with specific embodiment, method proposed by the invention is described further,
In the present embodiment, equipment is distributed apparatus, it is contemplated that the place of the usual not responsible service message of master control borad
Reason, is therefore arranged on master control token set on master control borad, and certainly, master control token set can be arranged at
On any veneer, or being arranged on third party device, the present embodiment is only to be arranged on master control token set
Illustrate as a example by master control borad.
As in figure 2 it is shown, the schematic flow sheet of a kind of flow control methods provided for the embodiment of the present invention, bag
Include following steps:
Step 201, business board sends token application message to master control borad.
Concrete, be provided with token requisition cycle in business board, business board when token arrives requisition cycle,
Send token application message to master control borad, token application message carries veneer numbering, adds token week
Phase, the information such as token number of application, for different veneers, token requisition cycle can be identical or different.
It should be noted that master control borad self can also have local token set, master control borad is according to the order of self
Board requisition cycle, generate token application message, and be this locality token set application from master control token set
Token.
Wherein, token application thresholding, token application thresholding=maximum allowable through-rate it are provided with in business board
* (token requisition cycle+propagation delay time), lack when the local token set of the veneer sending token application message
When the token quantity lost is less than or equal to the token application thresholding of self, the token of token application message application
Quantity be disappearance token quantity, when send token application message veneer local token set disappearance
When token quantity is more than the token application thresholding of self, the token quantity of token application message application is self
Token application thresholding.
Preferably, for master control borad and business board, when the token of himself arrives requisition cycle, permissible
Judge that the local token set of self is the fullest, when local token set is expired, master control borad and business
Plate does not generates or does not send token application message at this token requisition cycle, when local token set is discontented with
Time, master control borad and business board generate or send token application message.
Preferably, business board can also locally record non-response identification after sending token application message,
If when next token arrives requisition cycle, this non-response identification still exists, then business board is in this order
Board does not send token application message requisition cycle.
Preferably, this non-response identification can be configured so that and only exists a token requisition cycle, such as,
When this token arrives requisition cycle, there is non-response identification in this locality, then business board does not sends to master control borad
Token application message, and non-response identification is deleted.
Step 202, master control borad receives token application message.
Step 203, master control borad judges whether the token quantity in master control token set is zero, if result is yes,
Perform step 204, otherwise perform step 205.
Concrete, master control borad is provided with token increases cycle and token increase thresholding, whenever token increases
When cycle arrives, master control borad judges in master control token set, whether the token quantity of disappearance increases more than token
Thresholding, time if the determination result is YES, the token quantity that master control borad increases in master control token set is token
Increasing thresholding, otherwise, the token quantity that master control borad increases in master control token set is the token number of disappearance
Amount.The token exceeded in master control token set when frequency and the quantity of each business board application token is accelerated
Time, the token quantity in master control token set may be depleted.
Step 204, master control borad is numbered according to the veneer in token application message, sends order to corresponding service plate
Board entitlement message, the token quantity that this token grant message is distributed is zero, and performs step 207.
Step 205, master control borad is numbered and the order in master control token set according to the veneer in token application message
Board quantity, distributes token for corresponding service plate, and reduces the token of respective numbers in master control token set.
Concrete, master control borad may determine that whether the token quantity in master control token set is more than or equal to order
Board application message apllied token quantity；If the determination result is YES, master control borad is according to the numbered phase of veneer
Answer the token number that veneer distribution token application message is asked；If judged result is no, master control borad is according to list
All tokens that plate is numbered in just master control token set distribute to corresponding veneer.
Preferably, master control borad can record the token quantity that promising all veneers distributed, and according to dividing
The token quantity joined arranges priority from low to high for all veneers from more to less.When master control borad receives
During the token application message that business board sends, search priority according to veneer numbering, and judge this business board
Whether it is the veneer that priority is minimum, if the determination result is YES, master control board starting timer, work as timer
When time arrives, distributing token for this business board, otherwise directly this business board distributes token.
Step 206, the token of distribution is sent to business board by token grant message by master control borad, to increase
Token quantity in the local token set arranged in this veneer.
Step 207, business board receives the token grant message that master control borad sends, according in token grant message
The token quantity carried, increases the token quantity in local token set.
Preferably, if business board is locally recording non-response identification after sending token application message,
After receiving token grant message, business board deletes this non-response identification.
It should be noted that for centralized device, it is achieved flow process and the realization stream of above-mentioned distributed apparatus
Journey is similar to, and differs only in due to centralized device only one of which veneer, and therefore the set of master control token is with many
Individual local token set is safeguarded by each chip on veneer, for centralized device, there is not plate due to it
Between communicate, need not consider propagation delay time, therefore application this method can obtain compared to distributed apparatus more
Good speed limit effect.
For local token set, each veneer can be provided with multiple local token set, if veneer
Need for multiple local token aggregate requests tokens, its can a time unification that set will be for each
The token of ground token set application is sent to be provided with the list of master control token set by a combination message
Plate, sends token application message to avoid veneer to be individually for each local token set, and the plate caused leads to
Letter is frequent, and then the hydraulic performance decline produced.
The present invention passes through to arrange master control token set and local token set on veneer, and by being provided with master
The token quantity that the veneer of control token set is uniformly controlled in equipment in the local token set of all veneers,
Can realize multiple veneers or chip are carried out global traffic supervision, it is to avoid veneer or chip is actual passes through
Flow exceed and allow the flow that passes through.
Below in conjunction with specific embodiment, describe the present invention, in embodiments of the present invention, with
Master control token collection is combined into master control token bucket, local token collection is described as a example by being combined into local token bucket, right
In master control token bucket, its CBS(Committed Burst Size, maximum information frame sign can be promised to undertake) can
To be configured according to actual flow control strategy, its token increases the CIR that the cycle can be user's permission
(Committed Information Rate, can commitment information transfer rate), for local token bucket, examines
Considering to problems such as propagation delay times, the size of its CBS can be local token bucket CBS=this locality token bucket
CIR*(token requisition cycle+propagation delay time), with ensure veneer can before getting request token, with
The CIR allowed normally sends message, and herein, the CIR of local token bucket and master control token bucket can be different.
As it is shown on figure 3, in the present embodiment, veneer 1 is provided with master control token bucket and local order simultaneously
Being provided with local token bucket on board bucket, veneer 2 and veneer 3, in master control token bucket, residue token quantity is
90, the token of veneer 2 be requisition cycle 5s, local token bucket CBS be 500, real surplus token number
Amount is 300, and local token bucket CIR is 20.
As shown in Figure 4, a kind of flow control methods provided for the embodiment of the present invention, comprise the following steps:
Step 401, when the token of self arrives requisition cycle, and veneer 2 judges whether this locality has recorded and do not rings
Should indicate, if the determination result is YES, perform step 402, otherwise perform step 403.
Step 402, veneer 2 waits when next token arrives requisition cycle, returns and perform step 401.
Step 403, according to token requisition cycle and local token bucket CIR, veneer 2 determines that token application thresholding is
100, less than disappearance token number 200, therefore send token application message to veneer 1, ask 100 tokens,
And locally recording non-response identification.
Step 404, after veneer 1 receives the token application message that veneer 2 sends, it is judged that veneer 2 preferential
Whether level is minimum, if the determination result is YES, performs step 405, otherwise performs step 406.
Concrete, veneer 1 records the token quantity that promising veneer 1, veneer 2 and veneer 3 distributed.
Wherein, if the token quantity that veneer 1 distributed is 200, the token quantity distributed for veneer 2 is
400, the token quantity distributed for veneer 3 is 300, and veneer 1 is according to this record, by veneer 1, veneer 2
It is set to 1,3,2 with the priority of veneer 3, now performs step 405.
If the token quantity that veneer 1 distributed is 400, the token quantity distributed for veneer 2 is 100,
The token quantity distributed for veneer 3 is 300, and veneer 1 is according to this record, by veneer 1, veneer 2 and veneer
The priority of 3 is set to 3,1,2, now performs step 406.
Step 405, veneer 1 starts timer, wouldn't distribute token for veneer 2, and timer then after,
Perform step 406.
Wherein, if veneer 1 is before timer is not timed out, receive the token application message that veneer 3 sends, institute
The token quantity of request is 220, and veneer 1 determines that veneer 3 is not the veneer that priority is minimum, therefore to veneer
3 send token grant message, distribute 220 tokens for veneer 3, and are adjusted by the token number in master control token bucket
Whole is 80.
Step 406, the token application message that veneer 1 sends according to veneer 2, according to remaining in master control token bucket
Token quantity, return token grant message.
Concrete, if veneer 1 is before distributing token for veneer 2, it is assigned with 220 tokens for veneer 3, this
Time this locality token bucket in remaining token lazy weight 100, therefore distribute 80 tokens for veneer 2, and
Token number in master control token bucket is adjusted to 0.
If veneer 1 is when distributing token for veneer 2, the token quantity in local token bucket is more than or equal to 100
Individual, veneer 1 distributes 100 tokens for veneer 2, and by token grant message notifying veneer 2.
Step 407, after veneer 2 receives token grant message, according to the order carried in token grant message
Board quantity, increases the token in local token bucket, and deletes non-response identification.
In the present embodiment, arrange for its token Number dynamics distributed according to the priority of each veneer,
Such as, in the present embodiment, before this sub-distribution token, if the token quantity that veneer 1 distributed is 200,
The token quantity distributed for veneer 2 is 400, and the token quantity distributed for veneer 3 is 300, at this
After being assigned with 80 tokens for veneer 2, be assigned with 220 tokens for veneer 3, now, veneer 1 is veneer 2
The token sum distributed is 480, and the token sum distributed for veneer 3 is 520, and therefore, veneer 1 will
The priority of veneer 1, veneer 2 and veneer 3 is adjusted to 1,2,3.
