One more thing. I've found you have to set sysctls to get the setup right (particularly around seq_window size and ackvecs. Here is the script I use for CCID3: # sudo modprobe dccp sudo modprobe dccp_ccid3 sudo sysctl -w net.dccp.default.seq_window=10000 sudo sysctl -w net.dccp.default.send_ackvec=0 sudo sysctl -w net.dccp.default.rx_ccid=3 sudo sysctl -w net.dccp.default.tx_ccid=3 and CCID2: # sudo modprobe dccp sudo modprobe dccp_ccid2 sudo sysctl -w net.dccp.default.seq_window=10000 sudo sysctl -w net.dccp.default.send_ackvec=1 sudo sysctl -w net.dccp.default.rx_ccid=2 sudo sysctl -w net.dccp.default.tx_ccid=20 My opinion is that the send_ackvec should automatically change in the code when you change CCIDs. The default_seq_window increases from the default specified in the RFC of 100. Ian On 11/30/06, Ian McDonald <ian.mcdonald@xxxxxxxxxxx> wrote:
Hi Leandro, I'm doing some tests again today. Have you got some code/results you can share? Also can you both try 2.6.19 and see what that is like in comparison? Also are you using CCID2 or CCID3?

I have downloaded Dave's 2.6.20 tree and started using the DCCP implementation as out-of-the-box, i.e. without applying your patches. However, I am facing strange problems with that implementation: after sending 4-5 packets, the sender side becomes unable to send any more packets, despite of returning success code in the application layer - send API returns value > 0. > > > > > > Any comments? > > > > > > Thanks in advance, > > > Burak Gorkemli > > > PhD.
