It will be understood by those skilled in the art that the hardware configuration of flow switching equipment shown in Fig. 1 does not constitute convection current The restriction for measuring switching equipment may include perhaps combining certain components or different portions than illustrating more or fewer components Part arrangement.

As shown in Figure 1, as may include operating system, net in a kind of memory 1005 of computer readable storage medium Network communication module, Subscriber Interface Module SIM and flow changeover program.Wherein, operating system is to manage and control flow switching equipment With the program of software resource, network communication module, Subscriber Interface Module SIM, flow changeover program and other programs or software are supported Operation；Network communication module is for managing and controlling network interface 1004；Subscriber Interface Module SIM is for managing and controlling user Interface 1003.

In flow switching equipment hardware configuration shown in Fig. 1, network interface 1004 is mainly used for connecting system background, with System background carries out data communication；User interface 1003 is mainly used for connecting client (user terminal), carries out data with client Communication；Flow switching equipment calls the flow changeover program stored in memory 1005 by processor 1001, and executes hereafter The flow switching method.

Based on the device hardware running environment of above-mentioned flow switching equipment, the following of inventive flow switching method is proposed Embodiment.

Inventive flow switching method is preferably applied to distributed system, and same distributed system is deployed with multiple subsystems System, subsystem are that can realize inquiry business, son of transferring accounts for realizing the application program of specific business function, such as Query Subsystem System can realize that transferred account service, loan subsystem can realize loan transaction.In addition, distributed system uses multiple data centers mode Subsystem is disposed, same subsystem can be deployed in one or more data centers.

Specifically to indicate atom business in a distributed system to service, for example the service of withholing indicates button convenient for managing Money business, financial service indicate loan transaction etc..Difference service is distinguished by service identifiers (Topic).Execution business That is, realizing corresponding service, namely the calling being related between subsystem, thus flow can be generated between different sub-systems.

It is the flow diagram of one embodiment of inventive flow switching method referring to Fig. 2, Fig. 2.In the present embodiment, the stream Measure switching method the following steps are included:

Step S10 establishes the network connection between service requester and service provider and each message channel respectively；

In the present embodiment, the realization of service needs to establish the network connection between service requester and service provider, with For transmitting flow, interaction between the two is realized.

In the present embodiment, service requester refers to consumer's (called side of service, some corresponding subsystem) of service, service Provider refers to supplier's (the called side of service, some corresponding subsystem) of service.Service requester is (suitable by request message In calling message) it is sent to service provider, and then service provider is called to carry out business processing, service provider returning response (or not returning response).

Explanation based on above-mentioned distributed system is it is found that in a distributed system, different sub-systems may use identical Service, for example deposit subsystem, subsystem of providing a loan, subsystem of transferring accounts require using the service of withdrawing the money (such as by withdrawal subsystem Unite and the service of withdrawal be provided), that is, between deposit subsystem and withdrawal subsystem, providing a loan between subsystem and withdrawal subsystem, turning All there is flow transmission between account subsystem and withdrawal subsystem.To realize flow control, thus needs to transmit flow and carry out Switching.

The present embodiment realizes the two by multiple messages channel preferably between service requester and service provider Between network connection, while further realize to flow transmission switch over control.

As shown in Figure 3, it is assumed that there is message channel A, B to can be used for realizing the network between service requester and service provider Connection establishes one with message channel A, message channel B respectively preferably in service requester self-starting each with service provider Network connection, thus by message channel A and/or message channel B, to realize the net between service requester and service provider Network connection.

In the present embodiment, message channel refers to the channel transmitted to request message and response message.Message channel, which refers to, appoints What can be used to transmit the channel of message, including but not limited to as RocketMQ (message queue), ActiveMQ, The message queues such as RabbitMQ (namely message-oriented middleware), or can provide the physical network of message transmission, message-oriented middleware Physical hardware product etc..

In the present embodiment, service requester establish and message channel between connection, in particular to service requester with disappear Breath channel between establish physical connection so that service request can by between the message channel and service provider in object Message circulation can be carried out in reason, it is not intended that centainly there is message circulation.And service provider is established between message channel Physical connection is established between connection, in particular to service provider and message channel, so that service provider can be by this Message channel physically can receive the calling message of service requester.

Step S20 obtains the assignment of traffic ratio that this service requester calls service；

In the present embodiment, after establishing the network connection between service requester and service provider, service requester Request message can be sent to service provider, and then service provider can also be to service requester returning response message.For reality Now flow between the two is transmitted and is controlled, thus needs to carry out flow switching, it is logical that the present embodiment preferably passes through switching flow transmission Road is to realize that flow switches.

To realize the accurate switching control to flow, the present embodiment is preferably based on assignment of traffic ratio to be switched into flow Row control.Assignment of traffic ratio is distribution ratio of the service requester flow in each message channel.Namely assignment of traffic ratio is Percentages, numerical values recited is between [0,1], and same service requester calls the flow of same services, in each message The sum of distribution ratio on channel is equal to 1 (100%).

The present embodiment is unlimited for the configuration mode of assignment of traffic ratio.For example, in the configuration file of service requester Static assignment of traffic ratio is configured, is also possible to configure dynamic assignment of traffic ratio by independent third party.

Step S30, according to the assignment of traffic ratio, using preset this service requester of channel selecting algorithms selection Send the correspondence message channel of request message；

In the present embodiment, due to being equipped with multiple messages channel between service requester and service provider, and flow is accurate Switch the output channel it needs to be determined that each message, namely needs to carry out message channel selection.

Since message is initiated by service requester, the present embodiment is preferably by service requester as message channel Selecting party, to determine which message channel request message that each will be sent specifically uses and is transmitted to service and provides Side.

The present embodiment preferably calls the assignment of traffic ratio of service according to this service requester of acquisition, and use is preset The correspondence message channel of this service requester of channel selecting algorithms selection transmission request message.The present embodiment is for channel selecting The specific implementation process of algorithm is unlimited.

The request message is sent to service from service requester and is provided by step S40 by the message channel of selection Side.

In the present embodiment, after the sendaisle of message has been determined, the request message that can initiate service requester leads to It crosses selected message channel and sends service provider to, service provider carries out business processing after receiving request message, then again Response message is pressed into former message channel backtracking to service requester.

It should be further noted that service provider and service requester need to introduce consistent API, to carry out and take The transmitting and receiving processing of relevant message is called in business.

The present embodiment builds the network of service requester, service provider and each message channel by message channel respectively Connection, to set up multiple transmission channels of flow, and then convenient for each message to composition flow in different messages channel Between switch over.In addition, obtaining the assignment of traffic ratio that service requester each time calls service, further so as to according to stream Amount distribution ratio, determines message channel corresponding to each request message of service requester transmission each time, is disappeared by this Request message is sent to service provider from service requester by breath channel, and then is realized logical in different messages to each message Flow switching between road, is restarted, entire handoff procedure is smoother, and passes through distribution ratio of liquid flow due to that need not modify to match to postpone Value control flow switching, rather than process number, so that flow switching is more accurate.

Further, since the present invention is by message channel, build service requester, service provider respectively with each message The network connection in channel, to set up multiple transmission channels of flow, and then can be by configuring assignment of traffic ratio to flow Switching is controlled.

Therefore, in one embodiment, to be further convenient for carrying out centralized control to distribution ratio of liquid flow value, while avoiding adjusting Service requester or provider are had an impact when assignment of traffic ratio, it is therefore preferable that being matched by independent third party's configuration center Assignment of traffic ratio is set, and dynamic configuration is preferably carried out as needed by administrative staff to the specific value of distribution ratio of liquid flow value.

In addition, due to the present invention using by the network connection built between service requester and service provider come Flow is transmitted, thus assignment of traffic ratio can be set from subsystem level granularity or data center's level granularity, and then can be real Now to the accurate switching control of flow.

For example, switching flow by different sub-systems.For example deposit subsystem, subsystem of providing a loan, subsystem of transferring accounts calling take Money service, and by message channel A, B transmit flow, then it is settable deposit subsystem assignment of traffic ratio: message channel A's Distribution ratio is 0.3, the distribution ratio of message channel B is 0.7 (namely 30% flow walks message channel A, and 70% flow Walk message channel B)；The assignment of traffic ratio of loan subsystem: point that the distribution ratio of message channel A is 0.5, message channel B It is 0.5 with ratio；It transfers accounts the assignment of traffic ratio of subsystem: the distribution that the distribution ratio of message channel A is 0.2, message channel B Ratio is 0.8.

In another example switching flow by different data center rank, for example, if depositing subsystem in the flow of data center 1 Message channel A is walked, walks message channel B in the flow of data center 2, then settable deposit subsystem is in different data center Assignment of traffic ratio: the distribution ratio of message channel A is 1 in data center 1, and the distribution ratio of message channel B is 0；In data The distribution ratio of message channel A is 0 in the heart 2, and the distribution ratio of message channel B is 1.

As shown in the above description, the assignment of traffic ratio of the present embodiment has the advantage that

(1) process is smooth: dynamic adjustment assignment of traffic ratio as needed, and then can realize the smooth of flow handoff procedure Adjustment, the mutation without leading to flow transmission quantity because of flow switching.

(2) process is accurate, and risk is controllable: in a first aspect, assignment of traffic ratio can be adjusted from small to large, if flow switched Occur not meeting expected situation in journey, then being unlikely to high-volume influences calling service.Second aspect, can be by different sub-systems Switch flow, multiple subsystems one by one can be subjected to flow switching, all subsystems is avoided to use same assignment of traffic Ratio and to influence face too wide.The third aspect can switch flow by data center's rank, for example certain subsystem is in data center 1 Flow walk channel A, walk channel B in the flow of another data center 2.

In addition, distribution ratio of liquid flow necessary to only obtaining current service according to subsystem level and data center's rank Value, and then can avoid the waste to distributed system bandwidth and computing resource.

(3) in domination set: the administrative staff of leading flow switching can be by modifying the data of configuration center to concentrate adjustment Assignment of traffic ratio, and the adjustment process does not need service requester or service provider changes any configuration information.

(4) elasticity is strong:, also can base since the assignment of traffic ratio of the present embodiment is configured by third party's configuration center It is configured in the actual conditions of distributed system, thus this mode had both been suitble to the scene of a small amount of flow system flow switching of small enterprise, The scene of similarly suitable thousands of a flow system flow switchings.

(5) boundary is sensitive: since the assignment of traffic ratio of the present embodiment is artificially configured by third party's configuration center, because And it can guarantee that flow all accurately switches to corresponding message channel and transmitted, and may be not present the situation of flow sideslip.For example, Assignment of traffic ratio is determined according to random algorithm, then is difficult to ensure same flow, the distribution ratio on each message channel The sum of be equal to 1, while being also difficult to ensure that distribution ratio can be divided exactly by message bar number, than if any 100 message, wherein 33.33% message is transmitted by message channel A, and 66.67% message is transmitted by message channel B, due to 33.33% He 66.67% can not all be divided exactly by 100, and then lead to that there are the situations of flow sideslip.

Further, since assignment of traffic ratio is present in third party's configuration center, it is therefore desirable to from third party's configuration The heart obtains assignment of traffic ratio.In one embodiment, it is preferably obtained and is flowed from third party's configuration center by following any mode Amount distribution ratio.

Mode one: elder generation is from third party's configuration center dynamic acquisition flow of services allocation table and caches to local, then passes through Query service assignment of traffic table, to obtain the assignment of traffic ratio that this service requester calls service.

Mode two: inquiry request directly is initiated to third party's configuration center, by searching for the service of third party's configuration center Assignment of traffic table calls the assignment of traffic ratio of service with this service requester of dynamic acquisition.

In the present embodiment, since assignment of traffic ratio may be adjusted in third party's configuration center, it is therefore preferable that timing from Third party's configuration center dynamic acquisition assignment of traffic ratio.It should be noted that in above two mode, timing can be from the Tripartite's configuration center dynamic acquisition assignment of traffic ratio is also possible to not timing from third party's configuration center dynamic acquisition flow point With ratio.

In addition, as can be seen from the above embodiments, to realize the accurate control switched to flow, thus can be from subsystem level grain Degree or data center's level granularity are arranged assignment of traffic ratio.Therefore, the present embodiment can be according to the corresponding son of service requester Flow of services allocation table is searched by data center where system and the subsystem, calls service to obtain this service requester Assignment of traffic ratio.

Flow of services allocation table and assignment of traffic ratio are illustrated further below.

Flow of services allocation table is used to store the assignment of traffic ratio for the service that each subsystem needs to call, and each subsystem System is divided by data center.

Assignment of traffic ratio is distribution ratio of the service requester flow in each message channel.Namely assignment of traffic ratio is Percentages, numerical values recited is between [0,1], and same service requester calls the flow of same services, in each message The sum of distribution ratio on channel is equal to 1 (100%).

Table 1

Flow of services allocation table as shown in Table 1 above specifically presses subsystem level and data center's rank configuration flow Distribute ratio.Wherein, subsystem 1 calls assignment of traffic ratio corresponding to service T1 in data center 1 are as follows: message channel A Distribution ratio be 0, the distribution ratio of message channel B is 0.8, the distribution ratio of message channel C is 0.2；Subsystem 2 is in data Assignment of traffic ratio corresponding to service T1 is called in center 1 are as follows: point that the distribution ratio of message channel A is 1, message channel B It is 0 with ratio, the distribution ratio of message channel C is 0.

It further, is the flow diagram of mono- embodiment of step S30 in Fig. 2 referring to Fig. 4, Fig. 4.Based on the above embodiment Described in flow of services allocation table and assignment of traffic ratio explanation, the selection course of message channel is illustrated.

In the present embodiment, above-mentioned steps S30 further comprises:

Step S301 judges in the assignment of traffic ratio with the presence or absence of the distribution ratio equal to 1；

Step S302, and if it exists, the distribution ratio equal to 1 is then corresponded into message channel as this service requester and is sent All request messages correspondence message channel；

In the present embodiment, since assignment of traffic ratio is distribution ratio of the service requester flow in each message channel, because This, if flow needs to flow through certain message channel, the corresponding distribution ratio of the message channel is naturally larger than 0, similarly, if desired controls Flow processed is not passed through certain message channel, then only the corresponding distribution ratio of the message channel need to be set as 0.As in above-mentioned table 1 It is shown, since subsystem 1 is 0 in the distribution ratio of message channel A, it is logical that subsystem 1 calls the flow of service T1 to be not passed through Road A.

As shown in the above description, if desired control flow flows through some or certain multiple message channels, then only need to be by message The corresponding distribution ratio in channel is set as 1 or is set as being greater than 0 and the numerical value less than 1.Thus can only be from distribution ratio be 1 Or to be selected greater than 0 and in message channel corresponding to the numerical value less than 1.

In the present embodiment, since the sum of the distribution ratio of same flow on each message channel is equal to 1, if flow Distribute ratio in exist equal to 1 distribution ratio, then flow can be transmitted by only existing a message channel, other message channels due to Distribution ratio is unable to transport stream amount for 0, thus can uniquely determine the corresponding message channel of distribution ratio is selected work For the correspondence message channel for all request messages that this service requester is sent.

As shown in above-mentioned table 1, since subsystem 2 is 1 in the distribution ratio of message channel A, and in other message channels Distribution ratio be 0, therefore, subsystem 2 calls the flow of service T1 only to pass through message channel A and is transmitted.And if on adjusting Stating subsystem 2 in table 1 calls the flow of service T1 in the distribution ratio of each message channel, then the switching control of flow can be achieved.

Step S303 then will be greater than 0 and the distribution ratio less than 1 correspond to message channel as this service if it does not exist The correspondence message channel of requesting party's transmission request message；

In the present embodiment, if can only exist greatly there is no the distribution ratio equal to 1 in the distribution ratio of same flow In 0 and the distribution ratio less than 1 therefore will be greater than 0 and the distribution ratio less than 1 correspond to message channel and asks as this service The correspondence message channel of the side's of asking transmission request message.

Further, since the sum of the distribution ratio of same flow on each message channel is equal to 1, because all message may be not present The case where distribution ratio in channel is all 0, meanwhile, if the distribution ratio equal to 1 is not present in the distribution ratio of same flow, It certainly exists and multiple is greater than 0 and the distribution ratio less than 1.

As shown in above-mentioned table 1, subsystem 1 is the distribution ratio of message channel A is 0, the distribution ratio of message channel B is 0.8, the distribution ratio of message channel C is 0.2.When subsystem 1 calls service T1, the corresponding transmission channel of flow is logical for message Road B, C, namely there are multiple corresponding message channels.

Step S304, if this service requester sends the correspondence message channel of request message there are multiple, based on pre- If computation rule, message channel corresponding to each request message of this service requester transmission is determined.

In the present embodiment, for the accurate switching control for realizing flow, when selected is asked for the transmission of this service requester Ask the correspondence message channel of message there are it is multiple when, be based further on default computation rule, with determine this service requester hair Message channel corresponding to each request message sent.It is the equal of that there are multiple channels, then any selection one.

The present embodiment can carry out flow switching control for the data center where subsystem or subsystem, while can The transmission channel of each request message is accurately controlled, and then is realized to each message between different messages channel Flow accurately switch.

It is further alternative, in one embodiment, when the correspondence message channel that service requester sends request message exists When multiple, especially by following computation rule, determine this service requester send each request message corresponding to disappear Cease channel:

(1) flow dicing treatment is carried out to the request message that service requester is sent, to obtain flow proportional assignment Numerical benchmark.

In the present embodiment, the request message item number that message channel the is transmitted not only assignment of traffic ratio phase with the channel It closes, but also related to the sum of request message that service requester is sent.Since the request message that service requester is sent is At random, not timing and generate in real time, thus the sum of request message can not be obtained ahead of time, so can not determine flow by than The numerical benchmark of example distribution.Therefore, it is necessary to the request messages sent to service requester to carry out flow dicing treatment, by one The numerical benchmark that the quantity of the request message of flow stripping and slicing is divided in portion as flow.

The present embodiment obtains a flow stripping and slicing especially by following manner: when service requester sends request message, Each request message that accumulative service requester is sent obtains request message sum；When request message sum reaches preset number When value, then a flow stripping and slicing is obtained, while current request message sum is reset to zero, and add up this service again and ask Each request message that the side of asking is sent, to obtain next flow stripping and slicing.

(2) in same flow stripping and slicing, message channel corresponding to each request message in the stripping and slicing of this flow is determined.

2.1, when starting accumulative request message every time, using any message channel in selected message channel as this The correspondence message channel of service requester transmission request message；

2.2, during each accumulative request message, judge request message quantity that current message channel is flowed into Whether the ratio between default value reaches the corresponding assignment of traffic ratio in current message channel；

2.3, if so, the correspondence message that another message channel sends request message as this service requester is led to Road, and continue to judge that the ratio between the current message channel request message quantity flowed into redefined and default value is It is no to reach the corresponding assignment of traffic ratio in current message channel；Otherwise, continue to send request message to current message channel.

The present embodiment for ease of understanding calls service T1 to be illustrated with subsystem 1 in above-mentioned table 1 below.

Assuming that the request message total quantity in a flow stripping and slicing is 1000, request message sum is msgNum, is used for Each request message that accumulative service requester is sent.Since the distribution ratio of message channel B, C are both greater than 0 and less than 1, because This, sends the correspondence message channel of request message when message channel B, C are called service T1 as this subsystem 1.

1, when starting request message that accumulative subsystem 1 is sent, by first request message be sent to message channel B or Person's message channel C, it is assumed that selection message channel B sends request message；

2, while continuing to send request message to message channel B, the request for judging that current message channel B is flowed into disappears Whether the ratio (being set as K) between breath quantity and default value (1000) reaches the corresponding distribution ratio of liquid flow of current message channel B It is worth (0.8)；

If 3, reaching the corresponding assignment of traffic ratio of message channel B, namely when msgNum=800, K=0.8 is then needed Flow switching is carried out, specifically using message channel C as the flow transmission channel after switching；

4, while being switched to message channel C by flow and continuing to send request message, judge current message channel C institute Whether the ratio between the request message quantity and default value of inflow reaches the corresponding assignment of traffic ratio of current message channel C (0.2)；Wherein, the request message quantity that message channel C is flowed into can be obtained by msgNum-800.And when the numerical value of msgNum reaches When to 1000 namely K=0.2, since the numerical value of msgNum at this time has reached default value, then needs to enter next flow and cut The switching of flow transmission channel in block, while msgNum is set to 0 again.

Since assignment of traffic ratio is present in third party's configuration center, it is therefore desirable to obtain flow from third party's configuration center Distribute ratio.In one embodiment, ratio obtains module 20 and is preferably obtained by following any mode from third party's configuration center Take assignment of traffic ratio.

In addition, due to the present invention using by the network connection built between service requester and service provider come Flow is transmitted, thus assignment of traffic ratio can be set from subsystem level granularity or data center's level granularity, and then can be real Now to the accurate switching control of flow.Therefore, in one embodiment, ratio acquisition module 20 can be corresponding according to service requester Flow of services allocation table is searched by data center where subsystem and the subsystem, calls clothes to obtain this service requester The assignment of traffic ratio of business.

Table 2

Flow of services allocation table as shown in Table 2 above specifically presses subsystem level and data center's rank configuration flow Distribute ratio.Wherein, subsystem 1 calls assignment of traffic ratio corresponding to service T2 in data center 1 are as follows: message channel A Distribution ratio be 0.3, the distribution ratio of message channel B is 0.5, the distribution ratio of message channel C is 0.2；Subsystem 2 is in number Assignment of traffic ratio corresponding to T2 is serviced according to calling in center 1 are as follows: the distribution ratio of message channel A is 1, message channel B's Distribution ratio is 0, the distribution ratio of message channel C is 0.

Further, above-mentioned flow shifting device flow of services allocation table as described in the examples and assignment of traffic are based on Ratio explanation, is illustrated the selection course of message channel.

In the present embodiment, the channel selecting module 30 is specifically used for:

In the present embodiment, since assignment of traffic ratio is distribution ratio of the service requester flow in each message channel, because This, if flow needs to flow through certain message channel, the corresponding distribution ratio of the message channel is naturally larger than 0, similarly, if desired controls Flow processed is not passed through certain message channel, then only the corresponding distribution ratio of the message channel need to be set as 0.As in above-mentioned table 2 It is shown, since subsystem 2 is 0 in the distribution ratio of message channel B, C, subsystem 2 calls the flow of service T2 to be not passed through Channel B, C.

As shown in above-mentioned table 2, since subsystem 2 is 1 in the distribution ratio of message channel A, and in other message channels Distribution ratio be 0, therefore, subsystem 2 calls the flow of service T2 only to pass through message channel A and is transmitted.And if on adjusting Stating subsystem 2 in table 2 calls the flow of service T2 in the distribution ratio of each message channel, then the switching control of flow can be achieved.

As shown in above-mentioned table 2, subsystem 1 distributes the distribution ratio that ratio is 0.3, message channel B message channel A's Distribution ratio for 0.5, message channel C is 0.2.When subsystem 1 calls service T2, the corresponding transmission channel of flow is message Channel A, B, C, namely there are multiple corresponding message channels.

In the present embodiment, for the accurate switching control for realizing flow, when selected is asked for the transmission of this service requester Ask the correspondence message channel of message there are it is multiple when, be based further on default computation rule, with determine this service requester hair Message channel corresponding to each request message sent.

It is further alternative, in another embodiment of inventive flow switching device, disappear when service requester sends request The correspondence message channel of breath there are it is multiple when, channel selecting module 30 determines that this service is asked especially by following computation rule Message channel corresponding to each request message that the side of asking is sent:

The present embodiment for ease of understanding calls service T2 to be illustrated with subsystem 1 in above-mentioned table 2 below.

Assuming that the request message total quantity in a flow stripping and slicing is 1000, request message sum is msgNum, is used for Each request message that accumulative service requester is sent.Since the distribution ratio of message channel A, B, C are both greater than 0 and less than 1, Therefore, the correspondence message channel of request message is sent when message channel A, B, C being called service T2 as this subsystem 1.

1, when starting request message that accumulative subsystem 1 is sent, by first request message be sent to message channel A or Person's message channel B or message channel C, it is assumed that selection message channel B sends request message；

2, while continuing to send request message to message channel B, the request for judging that current message channel B is flowed into disappears Whether the ratio (being set as K) between breath quantity and default value (1000) reaches the corresponding distribution ratio of liquid flow of current message channel B It is worth (0.5)；

If 3, reaching the corresponding assignment of traffic ratio of message channel B, namely when msgNum=500, K=0.5 is then needed Carry out flow switching, it is assumed that using message channel C as the flow transmission channel after switching；

4, while being switched to message channel C by flow and continuing to send request message, judge current message channel C institute Whether the ratio between the request message quantity and default value of inflow reaches the corresponding assignment of traffic ratio of current message channel C (0.2)；Wherein, the request message quantity that message channel C is flowed into can be obtained by msgNum-500.

If 5, reaching the corresponding assignment of traffic ratio of message channel C, namely when msgNum=700, K=0.2 is then needed Flow switching is carried out, using message channel A as the flow transmission channel after switching；

6, while being switched to message channel A by flow and continuing to send request message, judge current message channel A institute Whether the ratio between the request message quantity and default value of inflow reaches the corresponding assignment of traffic ratio of current message channel A (0.3)；Wherein, the request message quantity that message channel A is flowed into can be obtained by msgNum-500-200.And work as the number of msgNum When value reaches 1000 namely K=0.3, since the numerical value of msgNum at this time has reached default value, then need to enter next stream The switching of the flow transmission channel in stripping and slicing is measured, while msgNum is set to 0 again.
