[AusNOG] Favourite ATM redundancy techniques?

ATM failover didn't really depend on the encapsulation.

AAL5 is what was used for things like CLIP, LANE etc
AAL2 IIRC was a video, CBR kind of encoding.

The vendor I used to (almost) work for had a Smart Switched Virtual Circuits system which rerouted VCs in case of failure.

What you can use will probably be vendor and hw specific.

(who used to build big ATM networks in the early/mid 90s).

Can someone with a better memory than me remind me of the best L2
failover mechanisms for ATM?
Any pros and cons for any variation in techniques (other than the obvious).

from memory AAL2 was different to AAL5...

I'll figure out how best to set it up once I remember it can be done.
No flames please, there are good reasons for these things sometimes,
you know...

cheers, tia
