Datagram Congestion Control Protocol

From draft-ietf-dccp-spec-11 <http://www.icir.org/kohler/dcp/draft-ietf-dccp-spec-11.txt>.

The Datagram Congestion Control Protocol (DCCP) is a transport
protocol that implements bidirectional, unicast connections of
congestion-controlled, unreliable datagrams. It should be suitable
for use by applications such as streaming media, Internet telephony,
and on-line games

To compile this protocol support as a module, choose M here: the
module will be called dccp.

If in doubt, say N.
