Hi Guys,

On move to improve the performance of SCTP stack and get rid of lower level NIO code, SCTP project is moving towards Netty.

Here is issue https://github.com/Mobicents/sctp/issues/12

The first draft code is committed at https://github.com/Mobicents/sctp/tree/netty. This is really draft and just reference so some load test can be done to compare the old NIO with Netty.

On first test I could achieve 15000 MAP messages/sec using MAP load test tool on below machine

Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz
64 bit
16 GB RAM (2GB each assigned to MAP Server and Client test)
cores 2
enabledcores 2
threads 4
CPU consumed approx 80% on CPU 1 and 2 (3 and 4 hardly used)

Your feedback is welcome.

Thanks and Regards,

Amit.

Hi Amit,

It's awesome!. Just a quick question to understand better what you are doing, are you using the OOTB SCTP libraries provided by Netty (https://github.com/netty/netty/tree/master/transport-sctp/src/main/java/com/sun/nio/sctp) or developing your own?

Best regards,

Antón

Hi Anton,

We fully use Netty library. Saying that we leverage NioSctpChannel

Hi Gaurav,

We use Netty 4.0.33

Underlying library is indeed lksctp for linux. I haven't tested for any other OS. Please feel free to comment if you are trying to test with other OS as well.
