RE: I-D ACTION:draft-coene-multi6-sctp-00.txt

Hi,

Thanks all for the responses. One other question (and perhaps this is
more suitable for the IETF TSVWG, but it is related to the SCTP
multihoming draft).

In the ADDIP I-D (draft-ietf-tsvwg-addip-sctp-08.txt), addresses can be
added/deleted as described therein. However, in the sockets API I-D
(draft-ietf-tsvwg-sctpsocket-07.txt), I see a system call
'sctp_getpaddrs()' which allows the upper layer to get all peer
addresses in an association. However, I do not see a notification
primitive informing the upper layer when an address has been
added/deleted per the ADDIP I-D. It would be relatively easy to code
this into an implementation, but shouldn't something like this be in the
sockets API I-D? Thanks.

Pete

Dear all,

the way Lode describes it is OK. However, there is some
room for implementations...

Best regards
