Detailed Description
Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is only exemplary and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details.

Where expressions like at least one of "A, B and C, etc. are used, the expressions should generally be interpreted in accordance with the meaning as commonly understood by those skilled in the art (e.g.," a system having at least one of A, B and C "shall include, but not be limited to, a system having a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In a unitized architecture, to route traffic to the correct target unit, a traffic routing table, such as a unit dimension table, may be designed that includes a second mapping rule. Assuming that there is an application deployed by a unitized architecture, the application can divide the range of the value range of the data according to the attribute value into different sections according to the data range distribution, so that different units process the data of different sections. For example, the last two bits of UserId (i.e., user ID, whose type is an integer value) may be used as a division basis, and the entire service cluster is divided into 5 units, the unit dimension table is shown in table 1 (for example only).
TABLE 1
Last two digits of userId | Target unit |
00,01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19 | Zone1 |
20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39 | Zone2 |
40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59 | Zone3 |
60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79 | Zone4 |

Referring to Table 1, traffic with the last 2 bits of userId of 00-19 is routed to Zonel, traffic with the last 2 bits of userId of 20-39 is routed to Zone2, and so on.
Taking Zone1 as an example, if it is abnormal or in consideration of load balancing, the processing performance is poor. Traffic originally routed to Zone may be routed to other units at this point, as shown in table 2, and may be routed to Zone4.
TABLE 2
Last two digits of userId | Target unit |
00,01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19 | Zone4 |

Referring to table 2, the last 2 bits of userid are traffic of 00-19 and 60-79, which will be routed to Zone4, zone1 will no longer accept traffic. At present, the flow switching takes a unit as a routing unit, the switching dimension is all services under a Zonel unit, the flexibility is poor, and the flow switching requirement of finer granularity cannot be met.
The embodiment of the disclosure provides a flow switching method, which comprises the following steps: and obtaining a service call request to be routed, wherein the service call request comprises a call identifier to be routed and a target service. And determining a second target unit based on a second mapping relation in a second mapping rule, wherein the second mapping rule comprises a second mapping relation between the to-be-routed call identifier and the second target unit. And under the condition that the call identifier to be routed does not exist in the first mapping rule, routing the service call request to a second target unit, wherein the second target unit is provided with the target service. Under the condition that the to-be-routed call identifier exists in the first mapping rule, if the target service is determined based on the first mapping relation, routing the service call request to the first target unit, wherein the target service is deployed in the first target unit, and the first mapping rule comprises the to-be-routed call identifier, the target service and the first mapping relation between the first target unit.
Compared with the mode of directly determining the second target unit through the to-be-routed call identifier according to the second mapping rule in the unit dimension table, in the embodiment of the disclosure, the first mapping rule and the second mapping rule can be combined, under the condition of performing service dimension flow switching, whether the target service performs flow switching is determined according to the to-be-routed call identifier, and after the target service is determined, the first target unit is determined so as to realize service granularity switching.
According to an embodiment of the present disclosure, after obtaining a service call request to be routed, first, it is determined whether there is a call identifier to be routed in a first mapping rule. And secondly, if the to-be-routed call identifier exists, determining whether the target service exists according to the first mapping relation. And if the target service exists, routing the service call request to a first target unit in the first mapping relation. In addition, if the first mapping rule does not have the to-be-routed call identifier or the target service of the service call request, determining that the second target unit performs routing according to the second mapping relation in the second mapping rule. By setting the second mapping rule and the first mapping rule, the flow switching requirement of the unit dimension or the service dimension can be better met, the switching granularity is finer, and the flexibility is higher.

The background management server may analyze and process the received data such as the user request, and feed back the processing result (e.g., the web page, information, or data obtained or generated according to the user request) to the terminal device.
It should be understood that the number of terminal devices, networks, units and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Fig. 2 schematically illustrates an architecture diagram of a flow switching system according to an embodiment of the present disclosure.
As shown in fig. 2, the flow switching system 200 of this embodiment may include a configuration center 210, a flow regulator 220, and N first units 231, 232, … … N (i.e., unit 1, unit 2 … … unit N), where unit 1 may be implemented by the a unit 110 in fig. 1, and other units are also similar to unit 1, corresponding to the hardware units in fig. 1. The solid line in fig. 2 is used to characterize the sending of the service invocation request and the dashed line is used to characterize the obtaining of the second mapping rule and/or the first mapping rule from the configuration center.
The configuration center 210 is configured to configure a second mapping rule and a first mapping rule, where the first mapping rule includes a to-be-routed call identifier, a first mapping relationship between a target service and a first target unit, and the second mapping rule includes a second mapping relationship between the to-be-routed call identifier and a second target unit. The traffic dispatcher 220 is configured to obtain the first mapping rule and the second mapping rule from the configuration center according to a service call request to be routed from outside the unit, and execute the traffic switching method according to the embodiment of the present disclosure. Each first unit is used for calling the target service in response to the service calling request, and the N first units comprise a second target unit and first target units. Each first unit is further configured to execute the traffic switching method according to the embodiment of the present disclosure according to the service call request to be routed generated in the unit. The route calculation module is configured to be disposed in the traffic conditioner and each first unit, so as to execute the traffic switching method according to the embodiment of the disclosure.
Referring to fig. 1 and 2, outside of the unit may refer to outside of the distributed system. The service invocation request to be routed outside the unit may be a service invocation request sent by the user to the distributed system using the terminal device 151, 152, 153. The service call request to be routed generated in the unit may be a service call request generated in each first unit, for example, in the process of executing the service call request sent by the user, call execution of a plurality of services is involved, and after the unit 1 receives the service call request outside the unit, the service call request in the unit may be processed and generated. Referring to fig. 2, when the unit 1 performs the request routing, if the target unit is the unit 1, the request is regarded as an intra-unit call request. If the target unit is not unit 1, then the request is considered a cross-unit call.
Referring to fig. 2, the invocation of the service may be implemented by an RPC framework, which is a remote invocation framework, such as Dubbo, gRPC, etc. framework. The consumer may be a node in the micro-service architecture that initiates the RPC call. The provider may be a node in the micro-service architecture that receives RPC calls. In RPC calls, a service call request contains, in addition to UserID, request parameters, return values, some additional information of the request, such as start time, end time of the request, interface definition of the target service, method list of the target service, timeout time of the service, etc., all of which are collectively referred to as request context.
According to embodiments of the present disclosure, acquisition of UserId may be responsible for invoking a particular module in the link, such as by a traffic conditioner (e.g., load balancing device 160) at the outermost traffic ingress outside the unit, and by the RPC framework at inter-modulation between micro-services within the unit. The target service is the micro-service that is currently requested by the transaction, and can be obtained from the request context.
According to the embodiment of the disclosure, the route calculation module may be a service running independently, or may be a component integrated by other modules on the link for use, and when implemented as a component, for example, may be made into a Jar to be integrated by other modules.
The flow switching method according to the embodiment of the present disclosure will be described in detail below with reference to fig. 3 to 5 based on the descriptions of fig. 1 and 2.

Further, a routing computation module within the traffic conditioner may obtain the first mapping rule and the second mapping rule from the configuration center.
Each first unit may obtain a service call request to be routed generated in the unit, and obtain a call identifier to be routed and a target service in the request. Further, the route calculation module within the first cell may obtain the first mapping rule and the second mapping rule from the configuration center.
Wherein the routing computation module may cache the first mapping rule and the second mapping rule locally without having to read from the configuration center every computation, thereby providing performance. Operations S302 to S310 may be performed using the route calculation module.

For example, a first mapping rule is configured in a service dimension table and a second mapping rule is configured in a unit dimension table, in which case the traffic routing table includes a service dimension table and a unit dimension table. Or the first mapping rule and the second mapping rule are configured in the same routing table, in which case the traffic routing table is a routing table.
Taking the configuration of the first mapping rule in the service dimension table and the configuration of the second mapping rule in the unit dimension table as an example, whether the call identifier to be routed has a corresponding entry in the service dimension table or not can be determined, and if yes, the existence is confirmed.
In operation S303, it is determined whether or not there is a target service in the first mapping relation. If yes, operation S304 is executed, and if no, operation S307 is executed.
In accordance with an embodiment of the present disclosure, in the case where there is a to-be-routed call identifier in the first mapping rule, in operation S303, if the target service is not determined based on the first mapping relationship, operation S307 is performed to route the service call request to the second target unit.
According to an embodiment of the disclosure, a call identifier column, a cell column and a service column may be included in the service dimension table, each cell under the identifier column may be configured with one or more call identifiers, each cell under the service column may be configured with one or more services, and each cell under the cell column is configured with a cell number. The data for each row may determine the mapping between call identifications, units, and services. Table 3 schematically shows the first mapping rule content of the service dimension table. The last two digits of "UserId" are the call identifier column, "target unit" is the unit column, and "service list" is the service column.
TABLE 3 Table 3
After the to-be-routed call identifier is determined in the service dimension table, the data where the to-be-routed call identifier is located comprises a first mapping relation, so that a service list in a service column of the row is obtained. It is determined whether the target service exists in the service list.
In operation S304, it is determined whether the first target unit exists in the first mapping relationship. If yes, operation S305 is performed, and if no, operation S307 is performed.
In operation S305, a first target unit is determined based on the first mapping relation.
And determining whether a unit number exists in the unit column in the row data where the call identifier to be routed is located, and if the unit number exists, taking the unit number as a first target unit.
In operation S306, if the to-be-routed call identifier exists in the first mapping rule, if the target service is determined based on the first mapping relationship, the service call request is routed to the first target unit, where the first target unit is deployed with the target service, and the first mapping rule includes the to-be-routed call identifier, the target service, and the first mapping relationship between the first target unit.
In operation S307, it is determined whether there is a call identifier to be routed in the second mapping rule. If yes, operation S308 is executed, and if no, the process ends.
According to embodiments of the present disclosure, referring to tables 1 and 2, the last two digits of the call identifier column "UserId" and the cell column "target cell" may be included in the cell dimension table, and each cell under the identifier column may be configured with one or more call identifiers, with each cell under the cell column being configured with a cell number. The data for each row may determine the call identifier, the mapping between the cells.
In operation S308, it is determined whether a second target unit exists in the second mapping relationship. If yes, operation S309 is executed, and if no, ending.
In operation S309, a second target unit is determined based on the second mapping relationship.
After the to-be-routed call identifier is determined in the unit dimension table, the data of the to-be-routed call identifier comprises a second mapping relation, so that the unit number configured by the unit column of the row is obtained. The unit number is taken as a second target unit.
In operation S310, if the to-be-routed call identifier does not exist in the first mapping rule, determining a second target unit based on a second mapping relationship in the second mapping rule, and routing the service call request to the second target unit, where the second target unit is deployed with the target service, and the second mapping rule includes the second mapping relationship between the to-be-routed call identifier and the second target unit.
According to an embodiment of the present disclosure, after obtaining a service call request to be routed, first, it is determined whether there is a call identifier to be routed in a first mapping rule. And secondly, if the to-be-routed call identifier exists, determining whether the target service exists according to the first mapping relation. And if the target service exists, routing the service call request to a first target unit in the first mapping relation. In addition, if the first mapping rule does not have the to-be-routed call identifier or the target service of the service call request, determining that the second target unit performs routing according to the second mapping relation in the second mapping rule. By setting the second mapping rule and the first mapping rule, the flow switching requirement of the unit dimension or the service dimension can be better met, the switching granularity is finer, and the flexibility is higher.
Fig. 4 schematically illustrates a flow chart of setting a second mapping rule according to an embodiment of the disclosure.
As shown in fig. 4, before operation S307, setting the second mapping rule of this embodiment includes operations S410 to S420.
In operation S410, N first units are obtained, wherein M services are deployed in each first unit, and N, M is an integer greater than or equal to 1, respectively.
In operation S420, a third mapping relationship between each first unit and at least one call identifier is set based on a first routing rule, where the first routing rule includes a setting rule using the unit as a routing unit, and the third mapping relationship includes a second mapping relationship.
Referring to fig. 1, 2 and table 1, for example, 5 first units Zone1, zone2, zone3, zone4, zone5 are included under a distributed system. In some embodiments, if the third mapping relationship is set according to the last two digits (between 00 and 99) of the userID, every 20 tail numbers may be divided into a section, and the userID in each section has the third mapping relationship with one first unit. For example, if the last two digits of the to-be-routed identifier userID are 00, the corresponding second target unit is Zone1, and a second mapping relationship exists between the last two digits. Wherein the last two digits of UserID from different users may be the same.
It should be noted that the present disclosure is not limited to setting the third mapping relationship according to the last two digits of UserID. For example, the settings may be by region identification, device identification, or identification that may characterize a user, etc. When the third mapping relation is set according to the region identification, the third mapping relation can be set between different regions and the first unit. When the device identifier is set, a third mapping relationship can be set between different terminal devices and the first unit. When an identification setting is made that characterizes a user, all requests of a user can be routed to a first unit.
According to an embodiment of the present disclosure, the traffic switching method of this embodiment further includes setting a first mapping rule, and specifically includes: and setting a fourth mapping relation between any calling identifier and any first unit and at least one service in the first unit based on a second routing rule, wherein the second routing rule comprises a setting rule taking the service as a routing unit.
Through the second mapping rule, traffic switching with the unit as a routing unit can be realized. On the basis, the first mapping rule is combined, and when the service call request is routed, the priority of the fourth mapping relation is higher, so that the target unit can be obtained according to the determined target service in the first mapping relation in the fourth mapping relation. Specifically, the service list mapped is determined by calling the identifier, and if the target service exists in the service list, the request is routed to the target unit through the mapping between the service list and the target unit, so that the service granularity is switched.
In some embodiments, only the unit dimension table may be used when no traffic switching is performed, as shown in table 1. In this case, when the flow rate in the cell dimension is switched, a certain cell number may be modified to a target cell to be switched, as shown in table 2.
In other embodiments, the unit dimension table may remain unchanged when traffic switching for the service dimension is performed, as shown in table 1. The service dimension table configures the mapping relation among the calling identification list, the service list and the target unit. Referring to tables 1 and 3, if traffic of two services, namely ServiceA and ServiceB, which should be originally sent to Zone1 is switched to Zone4 and the other services are not active, a fourth mapping relationship of UserID tail number intervals 00 to 19, zone4, serviceA and ServiceB may be set in table 3.
For example, in operation S302, it is determined that the identifier of the call to be routed does not exist in the first mapping rule, and if at this time or during the next routing, the service dimension is switched to the identifier of the call to be routed, and a certain service that is called by the identifier is routed to other units. Then a first mapping relationship between the call identifier to be routed and the first target unit, the target service may be set based on the second routing rule. The fourth mapping relationship in the service dimension table includes the first mapping relationship.
In other embodiments, for example, in operation S302, it is determined that the call identifier to be routed exists in the first mapping rule, and when there is a traffic switching requirement for the unit dimension on the basis of routing through the service dimension table, the mapping relationship in the service dimension table may be modified, or the unit number in the unit dimension table may be adjusted, and the corresponding mapping relationship in the service dimension table may be deleted. This is further illustrated by fig. 5 below.
Fig. 5 schematically illustrates a flow chart for traffic switching in the unit dimension according to an embodiment of the disclosure.
As shown in fig. 5, the flow switching in the unit dimension of this embodiment may include operations S510 to S520. The operations S510 to S520 may be performed alternatively or in combination. The first mapping relation comprises a call identifier list and a service list, wherein the call identifier list comprises a call identifier to be routed, and the service list comprises a target service.
At least one of the list of identifications, the first target unit, and the list of services is invoked in the first mapping relationship is modified in operation S510.
In operation S520, the second target unit in the second mapping relationship is modified to a third target unit.
If tables 1 and 3 exist together, when all traffic destined for Zone1 is to be switched to Zone4, an alternative way is to perform only operation S510, where the service list in the first mapping relationship is modified, for example, all services in Zone4 are filled in the service list. Alternatively, operations S510 and S520 are performed to delete the first mapping relation, that is, delete all of the call identifier list, the first target unit, and the service list, and modify Zone1 in table 1 to Zone4, as shown in table 2.
If tables 1 and 3 exist at the same time, in order to switch the traffic of ServiceA and ServiceB of Zone3 to Zone4, only operation S510 may be executed, a first mapping relationship is newly added, and mapping relationships between UserID tail numbers 40 to 59, zone4, serviceA and ServiceB are established. Or if the flow rates of ServiceA and ServiceB of Zone3 are to be switched to Zone4, the flow rates of ServiceA and ServiceB of Zone1 no longer need to be switched, and the UserID tail numbers 00-19 in the current table 3 are modified to UserID tail numbers 40-59.
Based on the flow switching method, the disclosure further provides a flow switching device. The device will be described in detail below in connection with fig. 6.
