delay-buffer-rate

For LSQ interfaces, delay-buffer rate as a percentage of the available interface bandwidth.

• Range: 1 through 100 percent

Delay-buffer rate, in bits per second (bps). You can specify a value in bits per second either as a complete decimal number or as a decimal number followed by the abbreviation k (1000), m (1,000,000), or g (1,000,000,000).

• Range: 1000 through 6,400,000,000,000 bps

  Note:

  Through Junos OS Release 13.3, the upper limit is 160,000,000,000 bps. Starting with Junos OS Release 14.1, the upper limit is 6,400,000,000,000 bps.

  Note:

  Starting with Junos 17.2R1, the default minimum delay buffer threshold for MPCs is changed from 4096 bytes to 1568 bytes. This change improves the delay of time that packets can spend in the buffer. However, this lower minimum delay buffer threshold is easier to exceed than before and can cause tail drops. Juniper recommends you configure sufficient delay buffer rate to reduce this impact. In CIR mode, for nodes that do not have a guaranteed rate configured, Juniper also recommends that you configure a delay buffer rate equal to the shaping rate.
