That service is probably very expensive. =20
There is no known way to provide cheap 10 wave protection. Not carrier =
grade. Protected 10 GigE service (LAN PHY 10 GigE) will tolerate a very =
high BER before switching. And the cost of switching STM64 is very high =
as well.=20
Bottom line is that it will cost more than two diversely routed 10 gig =
waves.=20
There is no real market for protected 10 gig waves. Occasionally a bank =
will request the service, but backoff as soon as they see the price tag. =
"Hopefully none of these customers had service and protect ckts that =
went down... I would be pissed as a ceo if that happen to my company. =
Hopefully level3's new service offering is 100@percent redundant as =
stated
The new service offerings include: - Protected Wavelengths: Level 3 now =
provides automatic protection-switching to a dedicated diversely routed =
wavelength in the event of a network failure. The protection switch, =
fully automated and managed by Level 3, happens at switching speeds =
approaching SONET restoration times. The single interface to the =
customer requires no additional capital cost for customer optical ports, =
and the diverse restoration path is fixed and fully known to the =
customer. These features allow customers to achieve fast restoration =
with predictable performance in their network without adding significant =
cost and routing complexity. -"
