From 446dec30c7f305ed1bb0092b0a8d9367d842a33f Mon Sep 17 00:00:00 2001 From: Andrea Bittau Date: Tue, 19 Sep 2006 13:10:11 -0700 Subject: [PATCH] [DCCP] CCID2: Tell DCCP to quickly check whether cwnd is available 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.
