A few notes on the topology distribution and importing process: First/****>>>*/You need to send me your csProviderEndpoint for your NSA and I will insert it into the NSA object for your network in the global topo file. This way everyone will get it. For Rio, I am being very constraining on topology. This is necessary to make sure every NSA sees the same topology, and so that where necessary we can easily assign any NSA to any of the test networks, and so we can minimize incidental changes that don't address Rio. So please bear with me on this for Rio. Each implementation will need to define their internal topology. I do not need to see that. And it need not be in rdf/owl...(It is possible to do so if you choose.) You need to define the "mapsTo" relations for STPs 1 and 4 in your respective network. I do not need to see this either as this is really intra-domain information. This mapsTo relation identifies the physical port in your internal topology that corresponds to the NSI STP. It should use a form that is recognized by your internal NRM and provides all the information the NRM will need to use that port in the provisioning process. You are welcome to modify or amend the topo file as you see fit. But you are not allowed change the fundamental model it describes. I will maintain a base global topology file. If there are features you think will be required or desired by all networks, please let me know. Thanks to all for your patience as we slog though these topology issues. Jerry
