If you order the Hulk option, as soon as you unpack the crate, the Hulk jumps out of the box and carries the BFR to the right bay. The logo on the board it a warning not shake the crate too much otherwise the Hulk will rip the box apart trying to get out early. So remember, when the raised floor collapses because it could not stand the combined weight of the forklift, the crate, the 12016 and the bozo that drives the forklift, it's because of the Hulk pictured on the link above.

You don't get it, me thinks. For lots of people here, networks are not a toy funded by the taxpayer's money, they're a tool to make money and popular wisdom that I have found being practiced here says that indeed you _do_ ask how much it costs before you buy it. I don't buy a million bucks peace of equipment because it looks cool and I just got funding. I buy a million bucks piece of equipment because I want ROI on it, and if the ROI is 500k over 5 years I actually don't buy it. Michel.

I wonder how much OC-768 linecards will go for; if it's consistent with 2OC192/POS-IR-SC some will be over a million list a pop. And you thought 12816 gear was pricey? Michel.

RE: WAN accelerator recommendations

I worked very heavily with the expand product line in 1999 thru 2001. Our site was one of the beta test sites for their frame-relay product. Their products are first class and yielded us fabulous results. Here's an extract from a CIO magazine article referencing my experience: Expand Networks of Roseland, N.J., builds network accelerators that save bandwidth by using several techniques. In one way, the accelerators can recognize the data packets in a single communications session, strip out their headers (which, by definition, are all the same), and replace them with a two-bit session number. Feargal Ledwidge, network manager for Irvine, Calif.-based Wyle Electronics, says he's seen a threefold to fourfold increase in effective bandwidth by using the products. "Without these accelerators we would probably have had to double our bandwidth purchases," he says. http://www.cio.com/archive/070100/et.html Bottom-line - their products rock and from what I hear just keep getting better & better Feargal Feargal Ledwidge Web Services Engineer NRT Web Services -----Original Message----- From: Michael Ray [mailto:miker@cotse.com] Sent: Wednesday, May 26, 2004 4:01 PM To: Matt Bazan Cc: nanog(a)merit.edu Subject: Re: WAN accelerator recommendations On Tue, 25 May 2004 16:02:57 -0700, you wrote: >Hello, > I'm looking for advice and recommendations on WAN (T1 speeds) >accelerator devices.

WAN accelerator recommendations

Hello, I'm looking for advice and recommendations on WAN (T1 speeds) accelerator devices. I've seen the literature on the offerings from Peribit, NetCelera and Packeteer and am looking for some real-world feedback. Can anyone provide me with their experiences using these products or similar? Thanks, Matt

Symantec Security Software New Feature Problems or rather making it appear that others have problems
by P.Schroebel 26 May '04

26 May '04

FYI, might as well be aware Norton Internet Security has evidently installed a new feature that pre-scans the inline html images prior to writing the images to the temp dir and displaying them in the web-browser. This is a good thing, right? Maybe or maybe not, as it is purportedly to protect clients from those nasty virus filled websites and spimmers. Well, it is also generating a huge amount of complaints because the user can see the page until the scan is finished, god forbid they pre-load images. Any hoot, with Norton Security active "verizon's page" loads in 2 mins and, when inactive the same page loads in 3 seconds. Same holds true on MCI's site and on CNET you can really see it drag. Kinda feels like the 1200 Baud Days again. In the end we will all hear that the sites are taking far too long to load, and the answer is to drop the client side firewall. That still doesn't sound good . . . Windows. Ref: Norton Internet Security 4.0 2002, 2003 & 2004 Windows Client Side. -Peter

insurance
by Eric A. Hall 26 May '04

26 May '04

What's the current state of insurance protection for things like DDoS attacks or other unbudgeted outages, and does anybody actually use it? "Given the choice between buying excess bandwidth/hardware/service versus paying an insurance premium that will likely cover spikes in such costs whenever they are needed, [insert comment here]." This is for my own use. Off-list is fine. Thanks -- Eric A. Hall http://www.ehsco.com/ Internet Core Protocols http://www.oreilly.com/catalog/coreprot/

You can run the same distance as you do with your 10G system. It;s mostly driven by dispersion, crosstalk and snr if you have many amps. Milage varies with span design, but is not much different than 10G (as the symbol speed is till 10G). > Can 10G optical amplifiers be used? Yepp.. -P
