ddebc973c5
Based on Arnaldo's earlier patch, this patch integrates the standardised CCID congestion control plugins (CCID-2 and CCID-3) of DCCP with dccp.ko: * enables a faster connection path by eliminating the need to always go through the CCID registration lock; * updates the implementation to use only a single array whose size equals the number of configured CCIDs instead of the maximum (256); * since the CCIDs are now fixed array elements, synchronization is no longer needed, simplifying use and implementation. CCID-2 is suggested as minimum for a basic DCCP implementation (RFC 4340, 10); CCID-3 is a standards-track CCID supported by RFC 4342 and RFC 5348.

Datagram Congestion Control Protocol (RFC 4340)
|
|
|
|
From http://www.ietf.org/rfc/rfc4340.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.

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.
|
|

Just say N.

This module allows for capturing the changes to DCCP connection
|
|
state in response to incoming packets. It is used for debugging
|
|
DCCP congestion avoidance modules. If you don't understand

what was just said, you don't need it: say N.
