2.2.2.2.1 Leaky Bucket Parameters Attribute (a=bucketinfo)

The bucketinfo attribute is defined for use at the SDP session level and consists of a list of leaky bucket parameter sets. Each leaky bucket parameter set specifies a streaming bit rate and a recommended minimum buffer size (to be used by a client) when streaming the content at the specified bit rate.

The syntax of the attribute is defined as follows.

  
 bucketinfo = "a=bucketinfo:" 
 bucket-parameter *( SP bucket-parameter )
 bucket-parameter = bitrate ";" buffer-window
 bitrate = 1*10DIGIT
 buffer-window = 1*10DIGIT
  

The bitrate parameter specifies the rate at which the content is streamed, in bits per second.

The valid numerical range of the bitrate parameter is from 0 to 4,294,967,265, inclusive.

The buffer-window parameter specifies the amount of data that is required to be buffered by clients if they are receiving the data at the bit rate given by the bitrate parameter. The value of the buffer-window parameter is expressed in millisecond time units. The valid numerical range of the buffer-window parameter is from 0 to 4,294,967,265, inclusive.
