- What we do need to do, however, is to strip out at least one optical
- channel and use it for global broadcasting over the physical network.
- The purpose of which is for the injection of some small message to some
- receiver, possibly for control or direct hops of some sort.
-
- This can be done by having an extra optical ring connecting all
- incoming links in each switch. The message immediately becomes broadcast
- everywhere, and a receiver with a suitable filter can recover it, check the
- address, and possibly accept it.
