-          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.  See RFC 4341 for further details.
-
-          CCID2 is the default CCID used by DCCP.

           within a factor of two of the sending rate of a TCP flow under the
