[sctp-dev] How to reduce time between message received and SCTPSACK sent

[Dennis Hjort]

Hi, 
 
I'm not really sure if it helps you in your case, but when we've done some
tests with small packetsizes, we needed to set the 
 
<http://openjdk.java.net/projects/sctp/javadoc/b10/com/sun/nio/sctp/SctpSock
etOption.html> SctpSocketOption<
<http://download.java.net/jdk7/docs/api/java/lang/Boolean.html?is-external=t
rue> Boolean> SCTP_NODELAY 
to true, disabling Nagle Algorithm, to boost performance, as we mainly use
SCTP for control-signalling, thus using several small 
packets spread over time, and the Nagle Algorithm wants to pack several
chunks together to improve performance, ie not useful in our case.

Hi, 

I'm using OpenJDK SCTP to develop sigtran application. I have a small issue
SCTP SACK message. When a data message is received at SCTP it acknowledges
that with a SACK, the issue I'm having is that there is a always 200ms delay
between request receiving and SACK sending. 

Is there a way I can reduce this delay?

I've attached the traces with this mail. 

Thanks in advance. 

regards,
Sandarenu.
