Hi Rohit,

there are no issues with the option in general, only that it is hard to implement
it on top of the sctplib... The sctplib does not provide a functionality like this.

There is no problem in implementing them in kernel implementations.

Best regards
Michael

Hi Michael,

Could you please tell me why this functionality will not be implemented. Are there any issues with the option(SO_REUSEADDRESS) in SCTP. The socketapi draft also does not say anything about this option. I would be thankful if you could explain the issues with usage of this option in SCTP.

Regards
Rohit Agrawal

Hi Thomas,

so why not return an error from the setsockopt call?

Best regards
