inquiry on using POS
by Jinwha Chung 23 Dec '10

23 Dec '10

Hi, there; First of all, thanks you all for your unintended and unnoticed help what I’ve got from nanog. I’m looking for a reference case of a point-to-point POS link. My potential customer asked me to configure their nodes using 40G POS interface cards. The distance of their nodes is between 10 km to 50 km. They are considering Cisco CRS for their core router. I’ve found that CRS has 2 kinds of POS card. One support only up to 2km. so, this one is out. >From the datasheet, the other one can support point-to-point connection up to 80km using this DCU. Dispersion compensating unit. I’ve talked about this configuration with people and no one would recommend those kind of things. Personally, I prefer 10G Ethernet with XENPAK ZR optics. Here is what I want to know. Is there anyone who are using POS with DCUs (without DWDM or something like that) between nodes of less than 80km apart? If there, would you recommend it to others?

Anyone have any opinion on a user friendly and low-to-mid-priced CWDM or DWDM system? We need to take one pair of dark fiber and get about 5-6 10G ports on both sides. This is the info that the DF provider has given us on the route: Operating Wavelength: 1310/1550nm Maximum Attenuation: 0.35 dB/km for 1310 wavelength 0.25 dB/km for 1550 wavelength Any suggestions would be tremendously helpful. thanks, -Drew

DDoS Detection with netflow?
by Thomas Magill 22 Dec '10

22 Dec '10

Has anyone run across any DDoS/anomoly detection applications that are based on netflow, preferable v9? I ran across a really old application called Panoptis, but it does not appear to have any recent development. Does anyone have any experience with this product or anything similar?

I think I just made up a word. :) > > So if it's illegal for you to put a letter inside a FedEx box, Bzzt! It's -not- illegal to put a letter inside a FedEx box. It just has to have the appropriate (USPS) postage on it, _as_well_ as paying the FedEx service/delivery fee. This is true if it is just the letter you're sending, or if it is a sealed letter -inside- a box/package being shipped.. Now _live_scorpions_, on the other hand, are someting that the USPS _will_ delive, but AFAIK no 'express' service will handle. (One discovers some of the strangest things when one actually sits down and *reads* the _complete_ rules/regulation on a subject. In this case, it's the "Domestic Mail Manual". Scorpions are 'addressed' in 601.9.3.10)

BT, the old, formally government-owned, then privatised, effective last-mile monopoly, was split up. (I believe in return for some more government cash to build infrastructure, but I could be wrong on the order of events). BT OpenReach is now responsible for wires on poles / in the ground, CO space etc, and has to sell access to these to other divisions of BT (Wholesale, Residential) in the same arms-length way they sell them to other ISPs. It doesn't always work *quite* like that, especially in respect of actually getting space and power in COs, but the framework is there... Regards, Tim.

[OT]: WCCPv2 and >gige?
by Adrian Chadd 22 Dec '10

22 Dec '10

Hi all, I have a customer who is looking for examples of WCCPv2 deployments for traffic levels > 3 gige (and above, up to 10ge.) Now I know that theoretically there's no reason why this shouldn't be the case, but as I don't have a lab of 10GE capable Cisco L3 devices, I'm unable to verify that level of behaviour. So, is anyone using WCCPv2 redirection on gige and 10ge interfaces, and mind sharing with me the equipment/configuration/IOS version? Thanks, Adrian
