Does anyone know where I can locate a list of DWDM networks deployed for
Education, Science & Research, and Commercialization?
We need to determine the practicality of DWDM use...

The UK research and Education network is based on a DWDM backbone as far
as I know. Some of the regional networks on the Janet backbone also use
DWDM.

The current technologies for DWDM have really made it technology
that's reasonably straight forward to deploy. The last
generation was a nightmare!
Tuneable optics, dispersion compensation, and ROADM have made
a substantial difference to deploying and operating DWDM networks.

Road Runner utilizes a volume based spam block from my understanding. If you
send over X amount of email in Y amount of time, they block you. You need to
create a rule that staggers the number of messages you send to all rr.com
domains so as to not trigger the threshold and become blocked. See h
I'm looking for someone to swap services with - we need a remote
nameserver/test point, preferrably somewhere other than North America, and we
can offer the same in return.
Ideally we'd just trade small VMWare images (40G disk/512M RAM) but I'm open
to other options as well.

Honestly I doubt we are blasting Road Runner that hard. When I look thru the
log files it really does not look that bad except for on the 19th. So I
would have to say this is not how they have chosen to block me.

alex,
In your talk, I agree that the CAN with your CWDM is not that expensive but you
also mention that the tighter DWDM with long haul optics is expensive ie

Yes, but in very specific cases such as older ZD, NZD fiber and SMF with 20 or
more lambdas (at 2.5 Gbps or less) and with Ultra long haul and ultra DWDM 600
- 800 miles, 25 nm spacing and fiber with too high a water vapor content and/or
higher impurities in the fiber. If you have less than opti

Anyone from Comcast (or anyone know anyone from Comcast) that can
contact me regarding a routing issue on their network? I'm seeing some
weird routing between a customer of mine and a /32 on our network.
Traceroutes from customer site to two adjacent /32's on our network
Working /32

Note that these addresses are advertised aggregated as a /19 from us
to our peers.
