- It depends on your viewpoint of "an all optical network". Ideally, you
- want the data to stay optical (not revert back to electronics at all)
- all the way from the interface of the generating computer/workstation
- to the interface of the receiving computer/workstation. In this
- scenario that makes ATM practically superfluous if you're going directly
- between computers, or at best makes ATM a LAN-level Layer 2 entity.
-
- If you are indeed postulating electronic ATM switches embedded in the
- all-optical network, it is no longer all-optical, and you lose a lot of
- the benefits of being an all-optical network.
