it's a diff from today's: git/acme/net-2.6.16.git To use it, you need to compile support for ack vectors and: setsockopt DCCP_SOCKOPT_CCID_RX and DCCP_SOCKOPT_CCID_TX to 2. CCID2 status: * Standard TCP congestion control: - AIMD of cwnd, slow start etc. * RTO timeouts: - Maintains RTT estimate and calculates RTO from that. - Doesn't support timestamp option. * Ack ratios [reverse path congestion control]: - Supported by "infrastructure" - Missing feature negotiation, so no ack ratio change. * ECN: - Correctly adjusts cwnd when packets are reported ECN marked. - Doesn't deal with ECN nonces. - No ECN support for reverse path congestion [receiving ECN marked ACK]. * No support for determining that flows go silent [ack an ack stuff]. I need to make the code solid and linux friendly. Then I will split the patch so hopefully arnaldo will agree to commit it. It currently includes, and will be split to: * connect() race condition: Connect, send and disconnect real fast. I don't remember details but, The socket will be transiting from SS_CONNECTING to SS_CONNECTED. However, connect will return -1 because DCCP will have moved to CLOSE by the time connect() checks status. * disconnect doesn't cleanup state: server sends close req. Client doesn't reply with close "fast enough". Server will never destroy socket. I still gotta think about this more though. * support for ack vector records * support for switching ccids * support for ccid2 Any feedback is appreciated. Specifically, if this code looks "promising" [i.e. eventually commitable], it would be nice if someone can indicate the major problems with it. [coding style, way of doing things, bugs, etc] I'll now work on making the code more solid and splitting the patches. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
