Re: A New TransAtlantic Cable System

Hi All. It appears we're discussing theoretical limits of silica-based glass here. The Press Release assertion talks about what a trader might experience. Hm. I would ask Rob Beck to clarify this point and inform whether the stated objective in the release accounts for the many o-e and e-o conversions on the overland part of the end-to-end trader connection, including the handoffs that occur in the NY and London metros. I know that terrestrially, i.e., here in the US, some brokerage firms and large banks (is there any longer a distinction between those two today?:) have used their clout to secure links that are virtually entirely optical in nature on routes that are under a thousand miles, but this is not an option on a submarine system that's intrinsically populated with electronics, never mind the tail sections that assume multiple service providers getting into the act. Rob? Anyone?

My first thought is that they've found a way to cheat on the 1.5. If you can make it work at 1.4, you get down to 52.2ms - but get it *too* low and all your photons leak out the sides. Hmm.. Unless you have a magic core that runs at 1.1 and a *cladding* that's up around 2.0?

Hey guys, Anyone knows how often does Level3 update their filters? I have a prefix in Europe which has a route-obj from Sunday, it's accepted in Level3 Europe from Monday, but in the US it's still not accepted. Thanks, Florin

re: Anyone can share the Network card experience

IMHO, Nothing beats a good intel NIC. I'm a big fan of the intel pro/1000GT. In terms of performance, I think it is more determined by the card chipset.

Rough cost for monitoring
by Eric Gauthier 05 Oct '10

05 Oct '10

Heya, I'm trying to quickly pull together some very rough budget numbers for purchasing a full monitoring system (network, server, security, facilities). Is there a source for rough unit costs? If not, does anyone have recent RFI pricing that they'd be willing to share? Eric :0

do you use SPF TXT RRs? (RFC4408)
by Greg Whynott 05 Oct '10

05 Oct '10

A partner had a security audit done on their site. The report said they were at risk of a DoS due to the fact they didn't have a SPF record. I commented to his team that the SPF idea has yet to see anything near mass deployment and of the millions of emails leaving our environment yearly, I doubt any of them have ever been dropped due to us not having an SPF record in our DNS. When a client's email doesn't arrive somewhere, we will hear about it quickly, and its investigated/reported upon. I'm not opposed to putting one in our DNS, and probably will now - for completeness/best practice sake.. how many of you are using SPF records? Do you have an opinion on their use/non use of? take care, greg
