RE: Virtual Token Ring Interface [7:519]
Ouch, it hurts my head trying to read that page!I think I saw that page when I was searching CCO for uses of the virtual token ring interface. It appears to be used in SNASw, but a previous post gave me the impression that it could somehow be used for more basic token ring study. The specific context was that we could avoid buying token ring routers if we used this other method. From what I've read so far, I still don't see how that is very feasible and I was hoping someone out there had done this before. I'll have to read the CertificationZone paper again and look for that specifically. Thanks all! John | Don't have time to look into this more deeply today.

I still struggle with the question of whether the token rotates in the opposite direction in the Southern Hemisphere. If so, would no IBM LAN operate precisely on the equator?

It does, except when you lift your whole network gently and flip it upside down. If so, would no IBM LAN operate precisely on the equator? (dons DrScience hat) You must be thinking of FDDI. Normally, tokens go round and round in the 2 rings, one clockwise and one counterclockwise, and go past each other without ever touching. However, when they would otherwise cross the equator, tokens reverse direction and switch rings. Sometimes, when that happens, they collide and give birth to exotic MAC layer protocols, which scientists like me study and write long monographs about. Thus were such wonders as BRAP and MLMA discoverd. -- "Someone approached me and asked me to teach a javascript course.
