Dear authors:

Please find some questions and suggestions:

- introduce the assumptions early in the doc (e.g. no reordering in the network)
- there could be a section explain what the tools are, e.g. CFN, ACK, Bitmap, before we use them
- can there be multiple fragmented packets in parallel (how so) ? 
- Can we interleave non fragmented packets?
- discussion on timeouts is probably missing here and there
- discussion on what the modes are could be expressed as a matrix with X ==  windowed or not (that's CFN=1 or more), and Y == type of acknowledgement (none, on-error, always). And in that matrix, it would help to figure which modes are available, and then have section to explain the pro/con, possible mitigation of the cons and applicability of each mode.

What do you think?

Pascal
