Worked example

Inputs

Bytes received on unvalidated path
1200 bytes
Bytes already sent
2000 bytes
Next datagram size
1200 bytes

Expected results

Remaining byte allowance
1600 bytes
Whole next-size datagrams
1 datagrams

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

{
  "received": 1200,
  "sent": 2000,
  "next": 1200
}

Accuracy and scope

Unvalidated address and QUIC three-times limit only; congestion control may further limit sending. Simplified analytical model; not a design recommendation or safety certification.
