We had a lot of discussions on list about finding the right solution for hop-by-hop congestion control and reliability for the overlay link protocol. The author team also continued that discussion separately, and, honestly, made no progress. So the -03 draft has the following interim solution.
- The main body of the draft includes a simple ack-based receiver and a stop and wait sender. - The TFRC and AIMD senders have been moved to an appendix. They work with the simple receiver. If TCP over UDP or a similar separate specification appears to gain traction toward standardization before reload is finished, we will support adopting such a solution in reload. If no such solution appears to be nearing consensus, we will have to revisit the best approach for a uncomplicated semi-reliable congestion control algorithm for UDP WAN links. Stop and wait is probably already fine for most LAN deployments.
