Two logical interface units, 0 and 1, are provisioned with a guaranteed minimum of 750 Kbps and 500 Kbps, respectively. For logical unit 1, the delay buffer is based on the guaranteed rate setting. For logical unit 0, a delay-buffer rate of 500 Kbps is specified. The actual delay buffers allocated to each logical interface are 2 seconds of 500 Kbps. The 2-second value is based on the following calculation:
- delay-buffer-rate < [8 x 64 Kbps]): 2 seconds of delay-buffer-rate
For more information about this calculation, see the JUNOS Class of Service Configuration Guide.
