+ CCID 2, TCP-like Congestion Control, denotes Additive Increase,
+ Multiplicative Decrease (AIMD) congestion control with behavior
+ modelled directly on TCP, including congestion window, slow start,
+ timeouts, and so forth [RFC 2581]. CCID 2 achieves maximum
+ bandwidth over the long term, consistent with the use of end-to-end
+ congestion control, but halves its congestion window in response to
+ each congestion event. This leads to the abrupt rate changes
+ typical of TCP. Applications should use CCID 2 if they prefer
+ maximum bandwidth utilization to steadiness of rate. This is often
+ the case for applications that are not playing their data directly
+ to the user. For example, a hypothetical application that
+ transferred files over DCCP, using application-level retransmissions
+ for lost packets, would prefer CCID 2 to CCID 3. On-line games may
+ also prefer CCID 2.
+
+ CCID 2 is further described in:
