Worked example

Inputs

Burst arrival rate
2000000 bytes/s
Service rate
1000000 bytes/s
Burst duration
0.1 s
Initial queue
10000 bytes
Queue capacity
80000 bytes

Expected results

Unbounded peak backlog
110000 bytes
Overflow bytes
30000 bytes
Post-burst drain time
0.08 s

How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "arrival": 2000000,
  "service": 1000000,
  "duration": 0.1,
  "initial": 10000,
  "capacity": 80000
}

Accuracy and scope

Fluid single-server queue; arrivals stop at burst end; no retransmission or packet granularity. Simplified analytical model; not a design recommendation or safety certification.
