RDS is UDP protocol with reliability added - it remains connectionless from the consumer perspective.

SDP is connection based - at least currently.

But as Roland said, RDS doesn't even have a Makefile.
I've reviewed some of it shortly after it got dropped in but
still need to go through alot more of the code.

The code that I've looked at doesn't appear to be written to any of the openib code. A Makefile wouldn't help, since I don't think that any of it would compile anyway. Porting it to openib will be a major rewrite.

2) include some docs on it's use and why RDS is better than SDP.

Does someone have a link to a doc or presentation on why RDS is better than SDP? Or better yet, some actual data showing how it provides better performance or scalability?
