CreateCenInterRegionTrafficQosPolicy - Cloud Enterprise Network

Creates a quality of service (QoS) policy for an inter-region connection on an Enterprise Edition transit router.

Operation description

Only inter-region connections created on Enterprise Edition transit routers support QoS policies.
Traffic scheduling applies only to outbound traffic on Enterprise Edition transit routers.

For example, you create an inter-region connection between the China (Hangzhou) and China (Qingdao) regions, and create a QoS policy for the transit router in the China (Hangzhou) region. In this case, the QoS policy can ensure bandwidth for network traffic from the China (Hangzhou) region to the China (Qingdao) region. However, the QoS policy does not apply to network traffic from the China (Qingdao) region to the China (Hangzhou) region.
CreateCenInterRegionTrafficQosPolicy is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the ListCenInterRegionTrafficQosPolicies operation to query the status of the task.
- If the QoS policy is in the Creating state, the QoS policy is being created. You can query the QoS policy but cannot perform other operations on the QoS policy.
- If the QoS policy is in the Active state, the QoS policy is created.

Prerequisites

Before you call the CreateCenInterRegionTrafficQosPolicy operation, make sure that the following requirements are met:

An inter-region connection is created. For more information, see CreateTransitRouterPeerAttachment.
A traffic marking policy is created. For more information, see CreateTrafficMarkingPolicy.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length.	123e4567-e89b-12d3-a456-426655****
DryRun	boolean	No	Specifies whether only to precheck the API request. Valid values: true: prechecks the request but does not create the QoS policy. The system checks the required parameters, the request format, and the service limits. If the request fails the check, an error message is returned. If the request passes the check, the `DryRunOperation` error code is returned. false: sends the API request. If the request passes the precheck, the QoS policy is created. This is the default value.	false
TransitRouterId	string	Yes	The ID of the transit router.	tr-8vbuqeo5h5pu3m01d****
TransitRouterAttachmentId	string	Yes	The ID of the inter-region connection.	tr-attach-r6g0m3epjehw57****
TrafficQosPolicyName	string	No	The name of the QoS policy. The name can be empty or 1 to 128 characters in length, and cannot start with http:// or https://.	nametest
TrafficQosPolicyDescription	string	No	The description of the QoS policy. This parameter is optional. If you enter a description, it must be 1 to 256 characters in length, and cannot start with http:// or https://.	desctest
BandwidthGuaranteeMode	string	No	The allocation mode of the guaranteed bandwidth. You can specify an absolute bandwidth value or a bandwidth percentage. Valid values: byBandwidth: allocates an absolute bandwidth value for the QoS queue. byBandwidthPercent (default): allocates a bandwidth percentage for the OoS queue.	byBandwidthPercent
TrafficQosQueues	array<object>	No	The information about the QoS queue. You can add at most three QoS queues in a QoS policy by calling this operation. To add more QoS queues, call the CreateCenInterRegionTrafficQosQueue operation.
	object	No	The information about the QoS queue.
QosQueueName	string	No	The name of the current queue. Each QoS policy supports at most three queues. You can specify a name for each queue. The name can be empty or 1 to 128 characters in length, and cannot start with http:// or https://.	nametest
RemainBandwidthPercent	string	No	The percentage of the inter-region bandwidth that can be used by the queue. Each QoS policy supports at most 10 queues. You can specify a valid percentage for each queue. For example, a value of 1 specifies that the queue can consume 1% of the inter-region bandwidth. Note The sum of the percentage values of all the queues in a QoS policy cannot exceed 100%.	1
Bandwidth	string	No	The absolute bandwidth that can be consumed by the QoS queue. Unit: Mbit/s. Each QoS policy supports at most 10 queues. You can specify a valid bandwidth value for each queue. For example, a value of 1 specifies that the queue can consume 1 Mbit/s of the inter-region bandwidth. Note The sum of the absolute bandwidth values of all the queues in a QoS policy cannot exceed the total bandwidth of the inter-region connection.	1
Dscps	array	No	The Differentiated Services Code Point (DSCP) value that matches the current queue. Each QoS policy supports at most three queues. You can specify at most 60 DSCP values for each queue. Separate multiple DCSP values with commas (,).
	integer	No	The Differentiated Services Code Point (DSCP) value that matches the current queue. Each QoS policy supports at most three queues. You can specify at most 60 DSCP values for each queue. Separate multiple DCSP values with commas (,).	5
QosQueueDescription	string	No	The description of the current queue. Each QoS policy supports at most 10 queues. You can specify a description for each queue. This parameter is optional. If you enter a description, it must be 1 to 256 characters in length and cannot start with http:// or https://.	desctest
