Comment #5 on issue 41 by jmacau...@gmail.com: Do we replace the replyTo field with a topology/NSA configuration lookup? http://code.google.com/p/ogf-nsi-project/issues/detail?id=41 This also leads to another point we need to document - NSA should not validate the requestorNSA element. At the moment OpenDRAC validates that the requestorNSA is a valid "nsnetwork" entry in topology. We are now saying that this is not a requirement as previously discussed. Also, the current assumption is that the requestorNSA element can be used to resolve to the physical protocol address of the requesting NSA. So to summarize this discussion: 1. We cannot enforce the requestorNSA to be a valid NSA or NSnetwork entry in topology. 2. The requestorNSA element can't be used to resolve to an endpoint address unless we introduce a formalized mechanism for all clients of the network to also be included in this mechanism. 3. Do we change the requestorNSA to just be an informational field, and therefore, do we need it at all?
