[NANOG] DWDM

[Scott E. MacKenzie]

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...

I'm a bit late on that, but I'd tend to think this is commonly done on  
their RIR aut-num object.
This should at least be true for Major Bandwidth providers.

The UK research and Education network is based on a DWDM backbone as far

DWDM.

Re: [NANOG] DWDM

[Neil J. McRae]

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.

I had experience with the former generation system from Nortel 
which although very reliable it was very resource intensive
to deploy new services, the latest CPL technology from Nortel
is a real breakthrough, for once a vendor has listened and understood
the challenges for operators and actively addressed our concerns.

[NANOG] Block: Road Runner Internal IP blacklist 72.22.18.105

[Clinton Popovich]

Greetings all,  I am having a bit of trouble with Road Runner, we have been
blocked repeatedly for email that I believe to have been sent out on the
19th.  I have about 50,000 customers sitting behind this old mail server
currently.  I have emailed back in forth with someone from roadrunner and
when he sends me back the spam example it is always from the 19th.

 

So far from the spam sent out on that day we have been blocked 5 times. 

 

Does anyone have a contact for Road Runner that I might be able to have.

Re: [NANOG] Block: Road Runner Internal IP blacklist 72.22.18.105

[Matthew Evans]

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 here for the 
limits: http://security.rr.com/spam.htm#ratelimit

Here's a link to get unblocked: http://security.rr.com/mail_blocks.htm

Good luck.

[NANOG] nameserver / test point swap

[Michael 'Moose' Dinn]

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.

So they'll block all the major ISPs smtp relays, but not the infected
PCs used to inject spam?  Smart.  Do their customers really accept this?

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.

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 here for
the limits: http://security.rr.com/spam.htm#ratelimit

Here's a link to get unblocked: http://security.rr.com/mail_blocks.htm

Good luck.

Greetings all,  I am having a bit of trouble with Road Runner, we have been
blocked repeatedly for email that I believe to have been sent out on the
19th.  I have about 50,000 customers sitting behind this old mail server
currently.  I have emailed back in forth with someone from roadrunner and
when he sends me back the spam example it is always from the 19th.



So far from the spam sent out on that day we have been blocked 5 times.



Does anyone have a contact for Road Runner that I might be able to have.



Thanks,

Here's a map showing some of the regional optical networks
run by the R&E community. There's a lot more unrepresented
here, especially in metro environments.

Highly practical, and the latest network planning tools seem

So they'll block all the major ISPs smtp relays, but not the infected

Re: [NANOG] DWDM More Details

[John Lee]

Scott,

Do you want

  CWDM - Course Wave Division Multiplexing -   >  100 nm optical 
spacing   1 - 10 x 2.5 - 10 Gbps lambdas
  DWDM - Dense Wave Division Multiplexing   -   =50 nm optical 
spacing  20 - 40  x 2.5 - 10 Gbps
UDWDM - Ultra Dense Wave Division Multiplexing -<50 nm optical 
spacing  40 - 80  x 2.5 - 10 Gbps

What size area do you want

CAN - Campus Area Network   1 - 5 MilesShort Optics, No amplifiers
   MAN - Metro Area Network 10 - 40 Miles  Medium Optics, No amplifiers
   WAN - Wide Area Network   150   Miles between In Line Amplifiers (ILA)  
Long haul optics, EDFA or Ramiun Amps
ULHWAN - Ultra Long Haul600 - 800 Miles between ILA, ULH optics, Ramiun 
Amps

What type of fiber do you want to use?

SMF, Zero dispersion, phase shifted, etc.. This one you usually cannot control 
fiber since it depends on who you lease or buy the fiber from.

Running the fiber cost the money.

There are now a large number of regional fiber providers with Level (3) having 
the "most available" dark or lite fiber nationally in the US.

Alcaltel/Lucent, ADVA, Ciena, Cisco and the Chinese are normal list of optical 
equipment providers and Siemens, Ericson and others.

Subscribe to Lightwave (at no charge) and look at the back issues for networks. 
Show up at Supercom or OFC or what is replacing them and get the latest on 
ROADM, full channel tunable lasers and maintenance costs.

What size of network do you want to grow to before replacing the optical link 
equipment including ILAs?

Most any org can cost justify a CWDM / CAN since you can add one fiber pair at 
a time and one lambda per fiber pair.

DWDM gear is much more expensive and is aimed at 20 to 40 lambdas per fiber for 
service providers while UDWDM and ULHWAN are aimed at trans oceanic links and 
are very very expensive.

DWDM gear is not expensive. Passive muxes cost little. Active 
transceivers cost money but not very expensive at all.

Re: [NANOG] DWDM More Details

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 
"Everybody knows how to do (active) xWDM by giving a lot of money to (insert 
vendor of choice]:"

When you talk about the tighter itu spacing for "real" DWDM and the lasers with 
fiber that can handle the power, jitter, chromatic dispersion et al. the optics 
you mention will not handle that.

We have all duct taped optical systems on campus for the lab "and across the 
state of Georgia" see the Peach Net map.

What is the largest number of lambdas you have actually run on a single fiber 
with your duct tape system and how bad was the optical cross talk?

I'd be curious to ask reverse question, did anyone *have* real problems
deploying duct tape systems, or power jitter chromatic dispersion is
vendor mumbo jumbo designed to make you buy their gear?

What I think you are referring to is known as the
Gordon-Haus effect.  This is related to the length
of a strand to the 3rd power, so I would guess for
modern optics / filters, it is a non-issue for 80k.

Re: [NANOG] DWDM More Details

[John Lee]

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 optimum fiber you need 
the additional optics and electronics to make it perform.

So my question is the same as the underliying one in your presentation which 
for Scott is what are you trying to do and there are several ways to reduce the 
cost or if you need the super neat, highest speed, longest run stuff you will 
pay for it.

Side note, I liked your two presentations.

In the RIPE region it might be reasonable to use the word "commonly".  
I think it's fair to say that elsewhere a more correct phrase might be  
"almost never".
