[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: draft-otis-fc-sctp-ip-00.txtA couple of comments: - This discussion should be moved onto the ips mailing list (ips@ece.cmu.edu) as further IETF work on FC-over-IP will occur there. Despite it's name, the fcoverip draft has not been an official work item of the ipfc WG. The use of the ipfc list rather than ips is completely understandable, as the draft was misnamed, nonetheless, further discussion should be on ips. - Wayland wrote: > I guess, what I'm trying to say is that someone should clearly state the requirements for > FCoverIP.

Not only is that a good argument, it is in fact basically the position of the IETF, as conveyed by the Area Directors to the authors of the FC-over-IP draft - congestion control is REQUIRED if the work is to advance in the IETF because otherwise the protocol would be unsuitable for the internet. Whether to have a retry mechanism is an engineering decision that can be made as the work progresses (an implementation that didn't have to buffer for retransmission might consume less memory than one that did), but congestion control is REQUIRED, period. Thanks, --David (co-chair of the ips WG-to-be) p.s. For those on ips and not ipfc, I'm going to forward the ipfc discussion in a separate message. --------------------------------------------------- David L.
