revised use cases (to send to NML)
Attached is a doc with revised use cases - revised from the set I sent out two weeks ago. I would like to send these to NML group for consideration - so hopefully we can talk about these Wed morning - June 24. John
Hello John, Do you actually have cases where users request connections that do not have the same input as output? (untagged vs tagged, or even untagged Ethernet vs SONET?) It seems kind of strange to me that actual users would request something like that. Jeroen. John Vollbrecht wrote:

Hello Jeoroen, In Geant we have several such circuits. An example of this is our Ethernet circuits to the US. These are presented to the customer as Gigabit Etherent and are handed over to the US as VC-4-7v carrying GFP encapsulated Etherent. This has to be done this way since there are currently no Ethernet wavelengths over the Atlantic.

Hi Jeroen - Untagged vs tagged exists. We don't have SONET to users at this point, but if we did I expect that we would have that as well. How likely it is depends on where you think circuit terminates. If the Link to the network is SONET (to a switch in another net) a VCG carrying GFP encoded ethernet might well be switched locally to a VLAN over Ethernet.

Okay, just checking :) I did not really expect it to happen.

I would argue that that would be a different use-case then as it is described right now. Providing a connection from a user to another domain, where it will be further relayed is quite different from providing a e2e connection to users. Jeroen.

not from the point of view of the provider. it actually happens - as Guy points out. John
