Re: [Ips] [rddp] STORM proposed charter - 31 May 2009 version

Hmm .. I read:

 

"but not limited to TCP with MPA markers and SCTP" as being motivated

by non-IP uses, e.g., InfiniBand and FC.  Arkady?

Thanks,

Did you mean "are not based on TCP" rather than "are not based on IP"?

Arkady was asking about connection setup for SCTP which the former fits but not the latter.

And here's what I just did to that bullet ...

(5) RDDP Connection Setup: Good support for MPI applications requires a small update to MPA startup functionality to allow either end of the connection to initiate. In addition, a couple of minor changes to RDDP connection setup (based on implementation experience) are needed to generalize it for effective use with protocols that are not based on IP.

I'm about to send the result to Lars for wider review ...

Thanks,

Arkady,

 

I'll beef up the bullet, but probably not with that

degree of specifics.  Thanks for pointing this out,

and I apologize for the delay in responding.

Thanks,
--David

David,

The description of RDDP MPA bullet is too narrow.

(5) RDDP MPA: Good support for MPI applications requires a small

update to MPA startup functionality to allow either end

of the connection to initiate.

This bullet should also cover ORD/IRD negotiation as part of

connection setup. Also current RDDP connection setup is part of MPA

spec which is primarily for TCP stream markers. This bullet should provide

RDDP connection setup for both TCP and SCTP and for any message based

protocol.

How about:

(5) RDDP Connection Setup: Good support for MPI applications requires a small

update to MPA startup functionality to allow either end

of the connection to initiate. Add RDMA Read credits to RDDP Connection

        Setup. Make RDDP connection setup to be applicable for any message based

        protocols, including but not limited to TCP with MPA markers and SCTP.

I hope it is not too late to beef up this bullet.

Thanks,

Arkady

What I believe is the final draft of the proposed charter

and added the info about T10 and T11 doc access.  This is
about to go out for wider review.

Also, a reminder that STORM discussion will stop cc:'ing
other mailing lists soon.  If you're interested in STORM
work, please subscribe to the storm at ietf.org mailing list:

Finally - this is a near-final reminder that the rddp at ietf.org
mailing list will be closing soon - all discussion of RDDP
protocols will move to the storm at ietf.org mailing list.

Thanks,
