The Global Grid Forum has build a Management Landscape Wiki page, with cooperation from different standards organization. The IETF section was contributed by Bert. I suggest that you have a look at http://testforge.ggf.org/sf/wiki/do/viewPage/projects.scrm-wg/wiki/HomeP age and let Bert know if there are any problems or inaccuracies that you would like to see fixed. Thanks and Regards, Dan
