Dear Franco, dear all, I have just read the latest document on Grid Network Services and I would like to share with you the paper here attached that was published in the Proceedings of ONDM 2005 (Feb. 2005 IEEE sponsored). I think the document fits weel in particular with section 2.2 GNS vs. "NS". Any feedback and discussion is more than welcome also toward contributing to the editing of the draft-ggf-ghpn-netserv-2. Best regards, Luca. -- --- Luca Valcarenghi, Ph.D. Scuola Superiore Sant'Anna di Studi Universitari e di Perfezionamento Sant'Anna School of University Studies and Doctoral Research Center of Excellence for Communications Networks Engineering (CEIRC) via G.
