This topic describes the syntax, description, parameters, and response parameters of throttling functions. This topic also provides examples of these functions.

limit_rate_after

Details about this function:
  • Syntax: limit_rate_after(n, unit).
  • Description

    Sets the upper limit of the data transfer rate.

  • Parameters
    • n: the upper limit. Data type: integer. If you do not specify the unit parameter, the unit is byte/s.
    • unit: the unit to measure the data transfer rate. Data type: char. This parameter is optional. Valid values of unit: K, M, and G. These values are not case-sensitive.
  • Response parameters

    If the function succeeds, true is returned. Otherwise, false is returned.

  • Examples 
    limit_rate_after(10, 'k')                                                                                                                                                              
limit_rate(1, 'm') 
//If the data transfer rate is lower than 10 Kbit/s, it is not throttled. If the data transfer rate is higher than 10 Kbit/s, it is throttled to 1 Mbit/s.

limit_rate

Details about this function:
  • Syntax: limit_rate(n, unit).
  • Description

    Sets the value to which you want to throttle the data transfer rate. The lowest data transfer rate that you throttle to is 4 Kbit/s. If you specify a data transfer rate that is lower than 4 Kbit/s, the data transfer rate is throttled to 4 Kbit/s.

  • Parameters
    • n: the lowest data transfer rate. Data type: integer. If you do not specify the unit parameter, the unit is byte/s.
    • unit: the unit to measure the data transfer rate. Data type: char. This parameter is optional. Valid values of unit: K, M, and G. These values are not case-sensitive.
  • Response parameters

    If the function succeeds, true is returned. Otherwise, false is returned.

  • Examples 
    limit_rate_after(10, 'k')                                                                                                                                                              
limit_rate(1, 'm') 
//If the data transfer rate is lower than 10 Kbit/s, it is not throttled. If the data transfer rate is higher than 10 Kbit/s, it is throttled to 1 Mbit/s.
