Setting Migration Rate Limiting Rules for a Migration Task

Function

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

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

task_id

Yes

String

The migration task ID.

Minimum: 1

Maximum: 36

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

User token.

The token can be obtained by calling the IAM API for obtaining a user token. The value of X-Subject-Token in the response header is the user token.

Minimum: 1

Maximum: 16384
Table 3 Request body parameters

Parameter

Mandatory

Type

Description

speed_limit

Yes

Array of SpeedLimitlJson objects

The information about the time range-based migration rate limiting rules.

Array Length: 0 - 5
Table 4 SpeedLimitlJson

Parameter

Mandatory

Type

Description

start

Yes

String

The start time of a period. The format is XX:XX.

Minimum: 0

Maximum: 255

end

Yes

String

The end time of a period. The format is XX:XX.

Minimum: 0

Maximum: 255

speed

No

Integer

The migration rate limit for the specified period of time. The value is an integer ranging from 0 to 1,000. The unit is Mbit/s.

Minimum: 0

Maximum: 1000

Default: 0

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: 10

Maximum: 100

Default: 10
