All,

As I mentioned on the call last week, I think we need another NSI protocol requirement as following:

The provider agent involved in the initial NSI request from an NSI requesting agent (in these cases, the requester agent acts as an end user or application), must take on the responsibility of replying back to the end user the result of the request. That is either a failure or success with the correct pointers or Global Identifiers. This needs to be true regardless of weather the initial provider agent uses chain or tree model to reserve a path.

This requirement will have implications on the intermediate messaging that take place between the requesting agents and provider agents along the path. I can also imagine that the messaging to uphold this requirement will be different for tree vs chain.

I hope this makes sense...

Kind regards,
Gigi
