If not enough cwnd is available, tell the sender to check again as soon as possible. This will increase CPU utilization (polling frequently for cwnd) but will improve network performance. That is, the sender will need to wait less before detecting the increase of cwnd. A better architecture would be for the CCID to call-back (or dequeue) from DCCP when it is able to transmit traffic---not the other way around as it currently occurs.
