The Burst Threshold value is defined as which of the following in queue bursting?

• A. Burst Threshold value
• B. Max Limit
• C. Burst Limit
• D. Utilization threshold

Answer: (A)

In queue bursting the idea is to allow a short spike above the normal rate after you’ve accumulated a certain amount of normal traffic. The Burst Threshold is that accumulation requirement: the amount of data (usually in bytes) that must pass at the normal rate before a burst is allowed. Once you hit this threshold, the queue can rise up to the Burst limit for the duration of the Burst time. This helps handle brief traffic spikes without keeping the high rate all the time. So the Burst Threshold value is the exact parameter that defines how much data must go through before bursting can start. It’s not the maximum burst rate (that’s the Burst limit), not a separate utilization threshold, and not the burst duration (that’s Burst time).
