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.

[INET_DIAG]: Move the tcp_diag interface to the proper place
With this the previous setup is back, i.e. tcp_diag can be built as a module,
as dccp_diag and both share the infrastructure available in inet_diag.
If one selects CONFIG_INET_DIAG as module CONFIG_INET_TCP_DIAG will also be
built as a module, as will CONFIG_INET_DCCP_DIAG, if CONFIG_IP_DCCP was
selected static or as a module, if CONFIG_INET_DIAG is y, being statically
linked CONFIG_INET_TCP_DIAG will follow suit and CONFIG_INET_DCCP_DIAG will be
built in the same manner as CONFIG_IP_DCCP.
Now to aim at UDP, converting it to use inet_hashinfo, so that we can use
iproute2 for UDP sockets as well.
Ah, just to show an example of this new infrastructure working for DCCP :-)

Enable this to be able to unload the dccp module when the it

has only one refcount held, the control sock one. Just execute
