Ubuntu

SCTP & DCCP support in Kernel

Asked by Karena Stannett

I am undertaking research on the new proposed transport protocol standards SCTP and DCCP. As part of this I am undertaking some network emulation and hence am looking for a linux distribution that includes support of SCTP and DCCP in the kernel.

Can anybody tell me if Ubuntu includes such support.

Please see
http://lksctp.sourceforge.net/
for information on linux kernel sctp and
http://www.linux-foundation.org/en/Net:DCCP
for information on linux kernel dccp

If there is anyone I can contact for further information if Ubuntu does support these protocols I would also appreciate information on how best to contact the relevant people.

Many thanks

Karena

About DCCP yes it is supported.

In kernel.
CONFIG_INET_DCCP_DIAG=m
CONFIG_IP_DCCP=m
CONFIG_IP_DCCP_ACKVEC=y
CONFIG_IP_DCCP_CCID2=m
# CONFIG_IP_DCCP_CCID2_DEBUG is not set
CONFIG_IP_DCCP_CCID3=m
# CONFIG_IP_DCCP_CCID3_DEBUG is not set
CONFIG_IP_DCCP_CCID3_RTO=100
# CONFIG_IP_DCCP_DEBUG is not set
CONFIG_IP_DCCP_TFRC_LIB=m
CONFIG_NETFILTER_XT_MATCH_DCCP=m
CONFIG_NET_DCCPPROBE=m

About LKSCTP well i not sure, SCP is enable by default in Ubuntu but i didn't find anything about LKSCTP.
Although you can still build custom kernels in your Ubuntu and install, please read https://help.ubuntu.com/community/Kernel/Compile

Hope that helped.

Thanks Pedro

I am not actually concerned whether it is the lksctp implementation that is used in the distribution. That is just an implementation that I know is available for the Linux kernel. You say SCP (do you mean SCTP) is enabled by default in Ubuntu, and if that is so (and you mean SCTP) then the distribution should met my needs.

If you could confirm this to be the case then that will be my question answered.

Thanks again

Sorry for the typo

CONFIG_IP_SCTP=m

It is default enabled in the kernel.
