I understand ATM mesh is an obsolete technology, with very limited throughput. I heard something recently about Foundry switches with have an advanced kind of STP, with active loops, not meshes, though.
Probably there are no commercial devices on the market which would fit the description.
See my previous post. As for ATM being 'obsolete', well one might say this with good reason, but not because it isn't used. The core is still dominated by ATM. Waitaminue, not just the core but the edges too: DSL is basically over ATM still. As for bandwidth, that isn't a problem for ATM, though it's easy to bitch about the mapping penalties incurred by putting packets over ATM cells over OC-N. On the other hand, having the ATM layer in there can complicate matters, and you don't need a lot of flow control if you're willing to give everyone globs of bandwidth. For both of these reasons and more G-PON is probably going to win out, and I'd suspect prices have already started to drop precipitously. -TD _________________________________________________________________ Need a break?
