Dear All Please find below a reflection on the GUNI presentation and discussion last week in GHPN RG. GUNI presentation (G. Zervas) * The presentation was focused on the updated version of the Draft. * After presenting slides on contributors, structure and scope of this draft, we provided a few slides on Usecases describing different proprietary solutions developed or under development to interface Grid and Network provisioning systems. * A long discussion on these slides (slides 10-18) was held between the presenter, Eduard Escalona, Richard Hugues-Jones, John R. Vollbrecht, Anand Patil, Inder Monga <https://forge.gridforum.org/sf/global/do/viewUser/imonga> and Cees de Laat. The discussion concerned the interaction between Grid and Network provisioning systems and how the network resources are provisioned. * On slide 21 there was also useful discussion and interaction on the focus and the scope of this draft and in general the GUNI specification. The contributors of this draft proposed that a vertical interface (Grid-to-Network) can be also adapted for a horizontal one (Network-to-Network). * After a long discussion Richard Hugues-Jones suggested to focus the work of GUNI only on the vertical interface (Grid service layer and Network service layer). * There was also a suggestion for incorporating the Grid application requirements from Inder Monga. The involvement of experts from the Grid Middleware WGs was proposed from Wolfgang Ziegler. * It was also decided that there is a clear need to work towards the formation of a working Group targeting the formal standardization of the Interface. A WG Charter will be submitted and a BoF will be organized at OGF23 to consult the wider community.
