Hi, first, one general question from my side: I'm not sure if I understand the problem you are addressing. If you always take the smaller cwnd and be never more aggressive than standard TCP, how can you solve the problem that TCP is too slow in large BDP networks? Even when all network nodes support your ERN protocol (and all endsystems using these nodes), you still will not increase fast than standard TCP...?
Then I don't understand how you change the E2E cwnd. If the sending rate is limited by the ERN protocol you should not increase the E2E cwnd as your E2E feedback would be related to the smaller cwnd of the ERN protocol. If you don't increase the E2E any further and then halve on loss, you will probably underutilize the bottleneck link. Is this correct?
