in RFC 3448. The following values have been suggested as bounds for
experimental use:
- * 16-20ms to match the typical multimedia inter-frame interval
- * 100ms as a reasonable compromise [default]
- * 1000ms corresponds to the lower TCP RTO bound (RFC 2988, 2.4)

The default of 100ms is a compromise between a large value for
efficient DCCP implementations, and a small value to avoid disrupting
