currently not working:
IO::Socket::INET->new('Proto'    => 'sctp');

very small and simple fix:

I'm not sure this is the most sensible of behaviors. sctp can be used as
both a SOCK_STREAM and a SOCK_SEQPACKET: but the former doesn't really
make sense (what'd be the advantage over tcp?).

[toddr]

Given no response to the comment made by @Leont in 2012, I'm going to close this. Please re-open if you still would like to discuss this further.

[Leont]

I do think this ticket is valid, but realistically it needs Socket to have more SCTP support

[toddr]

How would you like to action this then? Do we want a perl RT about this?

[Leont]

IMO we should improve our sctp support, the question is should it be SOCK_STREAM or SOCK_SEQPACKET by default. @leonerd got an opinion?

[leonerd]

I don't really know enough about SCTP or the uses of it to suggest either way

[FGasper]

@Leont Perhaps rather than just sctp, there could be both sctp_one (SOCK_STREAM) and sctp_many (SOCK_SEQPACKET)?

Both interface styles are of legitimate interest.
