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

    "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.

    POST https://{endpoint}/v3/tasks/a45a300b-86b5-4b13-8802-52274fa43016/speed-limit

{
  "speed_limit" : [ {
