HI Joe, Yes I agree. But still there are finer features and BCP for api and protocol implementations that have appeared from the api's defined outside of the IETF and for which one need to look outside of RFC docs. Or for PUSH bit one can also look at RFC1122 which describes it as optional. BR,

Hi Michael, [Karen ] TCP maps the received soft destination unreachable ICMPs to ENETUNREACH or EHOSTUNREACH pending errors on socket. OK. FreeBSD provides EHOSTUNREACH instead of ETIMEDOUT for TCP. It doesn't support ENETUNREACH. I don't think we do this in SCTP... [Karen ] Yes. We do this

HI Michael, Agreed, however the other ways that SCTP doesn't pass validated ICMPs to the user seems like a mistake to me. [Karen ] I agree and we have for our SW recently discussed as to whether we should implement such notification following the UDP and TCP semantics. But at present none

HI Michael, [Karen ] This might (the MAY) results in hard trouble if the association is closed due to entering of dormant state. That's why we believe that this MAY reaction should be coupled with robust dormant state handling. I think we have to distinguish two things here: [Karen ] Yes, I
