Setting Migration Rate Limit Rules for a Migration Task

Function

This API is used to set migration rate limit rules for a migration task.

Calling Method

For details, see Calling APIs.

URI

POST /v3/tasks/{task_id}/speed-limit

**Table 1** Path parameter
Parameter	Mandatory	Type	Description
task_id	Yes	String	The migration task ID. Minimum length: 0 characters Maximum length: 255 characters

Request

**Table 2** Request header parameter
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	X-Auth-Token The user token. The token can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token. Minimum length: 1 character Maximum length: 16,384 characters

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
speed_limit	Yes	Array of SpeedLimitlJson objects	The information about the time segments when the migration rate is limited. Array length: 0 to 65,535

**Table 4** **SpeedLimitlJson** field description
Parameter	Mandatory	Type	Description
start	Yes	String	The start time of a segment. The format is XX:XX. Minimum length: 0 characters Maximum length: 255 characters
end	Yes	String	The end time of a segment. The format is XX:XX. Minimum length: 0 characters Maximum length: 255 characters
speed	Yes	Integer	The migration rate limit for the specified period of time. The value is an integer ranging from 0 to 1000. The unit is Mbit/s. Minimum value: 0 Maximum value: 10000
over_speed_threshold	No	Double	The overspeed threshold for stopping migration. This is a protection measure. If the migration speed exceeds the threshold, the task is stopped. It is used to control the consumption of resources (especially network bandwidth) during the migration to ensure that the overall system performance is not affected by a single migration task. The unit is percentage. Minimum value: 0 Maximum value: 100

Response

Status code: 200

details	Array of details objects	The error message. Array length: 1 to 20

**Table 7** **details** field description
Parameter	Type	Description
error_code	String	The SMS error code. Minimum length: 0 characters Maximum length: 65,535 characters

Example Request

This example limits the speed of a migration task to 20 Mbit/s from 0:00 to 8:00, 50 Mbit/s from 8:00 to 15:00, and 25 Mbit/s from 15:00 to 23:59. It also sets an overspeed threshold for the task.

POST https://{endpoint}/v3/tasks/7a9a9540-ff28-4869-b9e4-855fbe12xxxx/speed-limit

{
  "speed_limit" : [ {
    "start" : "00:00",
    "end" : "23:59",
    "speed" : 1000,
    "over_speed_threshold" : 50.0
  } ]
}

This example updates the migration rate limit rules of the task whose ID is a45a300b-86b5-4b13-8802-52274fa43016.
