Re: best effort has economic problems

Tier 1 operators do not do "best effort" really, at least not in their
cores (and they have the SLAs to back it up). They buy hugely expensive
top notch gear (Cisco 12000 (and now CRS:s) and Junipers) to get the big
packet buffers, the fast reroutes and the full routing table lookups for
each packet to avoid the pitfalls of flow forwarding the cheaper platforms
have.




When 12016s are on ebay for $12,000, even a low budget "tier 3" can
afford proper routing gear... It's not as if the Internet is still
powered by 7507s! (Well, a large part still is. :-)




Now, how will this translate in cost compared to DWDM equipment and OPEX

part of the whole equation?


I am starting to see some interesting long-distance 2.5Gbps CWDM gear
offered by European manufacturers, with 70km and 100km distance ratings.
This stuff sells for a fraction of the price of equivalent
Nortel/Ciena/Cisco ONS gear. Lots of optics companies are making 70km
rated SFPs in 8 or 16 wavelengths now. So far it only runs at OC-48
speeds, but 10Gbps will be coming soon.
