Datagram Congestion Control Protocol (RFC 4340)

From http://www.ietf.org/rfc/rfc4340.txt:
|
2005-08-10 11:14:34 +08:00
|
|
|
|
|
|
|
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,
|
2006-10-25 07:17:51 +08:00
|
|
|
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 :-)

Only use this if you're hacking DCCP.

When compiling DCCP as a module, this debugging output can be toggled
|
|
|
|
by setting the parameter dccp_debug of the `dccp' module to 0 or 1.
