This is a quick note to discuss path descriptions that might be received by a Provider Agent P1 when making a request. 1) simple path [A ->Z] A and Z are ports on the network known to (or findable by) P1 2) Multi-hop path [A -> B -> C -> Q ->Z] A, B, C, Q and Z are ports on the network know to (or findable by) P1 3) Strict -hop path [A -> B -> C -> D -> Z] A, B, C, D, and Z are ports on the network known to (or findable by) P1 Comment - I am not sure there is a difference between 2 and 3. I started thinking 2 was loose hop, 3 was strict hop. Now I think they are the same as far as the requestor is concerned. 4) Mid-chain path [A *-> B* -> C -> Z] A *-> B* -> C is outside the request but is included as part of the chain being requested There may be other path descriptions for requests. When responding to a request 1) simple path [ A<->Z] 2) multi-hop path [A <-> B <-> C <-> D <->Z] 3) Mid chain path [A*-> B *-> C <-> D <-> Z] Finally, the times that one uses a path 1) request instantiation of a path that has been reserved 2) request timed [phase 1] scheduling of resource 3) request commited [phase 2] scheduling of resource I don't know if there is a time for introducing this at the meeting Tuesday, but I submit this for possible discussion.
