When the usage levels between users can be more than 100 to 1 it can't be fair.

I do so love a challenge. Here's some examples of the theory:

• Beyond Best Effort: Router Architectures for the Differentiated Services of Tomorrow’s Internet (1998)
• The Impact of Active Queue Management on Multimedia Congestion Control (1998)
• Comparison of Tail Drop and Active Queue Management Performance for bulk-data and Web-like Internet Traffic (2001)
• Bandwidth Allocation for Non-Responsive Flows with Active Queue Management (2002)
• A Comparative Study of Active Queue Management Schemes (2004)
• PURPLE: Predictive Active Queue Management Utilizing Congestion Information (2003)
• The Addition of Explicit Congestion Notification (ECN) to IP (2001)

And here's some examples of the practice with CISCO routers:

• WRED
• DWRED
• ECN within WRED
• Hierarchical Queueing Framework

Other systems:

• Juniper's support for WRED and QoS in general
• QoS in HP ProCurve switches
• QoS in Nortel switches

Now, tell me again that only a Marxist would believe that it's possible to have pipe-based fair-service on the Internet.

On the off-chance that you're not trolling:

C = Cisco Systems
N = Nortel
J = Juniper Networks

HTH. HAND.

..despite the fact that he's the only blogger that focuses solely on Nortel..

Nortel JDS

Somehow its news if IBM does it? Ask Nortel and JDS, the market just is not there. Though perhaps they can flog their warehouses full of this stuff at IBM, if IBM thinks the telco's are willing to replace the copper network with fiber. (fat chance)

And who is going to lay fiber to my house? They've been talking about it since 1989. It's not going to happen. The cable company won't even lay coax out here. (and I'm only a 20 minute drive from an urban center).

Fiber to the home? I'll believe it when I see it, and I doubt I ever will. (And no, prototype communities don't count. It must be as ubiquitous as copper is today.)

Telus is actually a fairly progressive company. They even started using VOIP for long distance back in 2002. Home Internet service is quite reliable (they don't even shape bittorrent traffic, that I'm aware of), and they're often upgrading ADSL service at no extra charge (though I splurged for a 6.0/1.0 connection at $45/mn). They also stand up for their customers, refusing to give out customer details without a subpoena, etc. The Mobility division (cell phones, etc) is also quite competitive, though they do rape you with long distance charges on cellphones, but no one has the same coverage they do. Honestly, this latest move doesn't surprise me too much (though I was surprised when it first showed up on my cell's browsing homepage).

If you are a small company, listen to Security Now! early episodes http://grc.com/securitynow that cover VPNs. They spent about 6 episodes on VPNs.

If you don't need free and have a few thousand users to support, combining RSA/SecurID, ACE, and Nortel products like Shastas or Contivity Extranet Switches are excellent. If you don't need the flexibility of a Shasta, the CES line is under $20k to support 2k users. http://www.nortel.com/solutions/smb/business_solut ions/comparisons/contivity_1000.html
http://products.nortel.com/go/product_assoc.jsp?se gId=0&parId=0&prod_id=19940&locale=en-US&rend_id=F B You can use SecurID tokens from a different vendor that don't expire after 3 years and are fully compatible with SecurID one-time passwords. Highly recommended.

If you are really looking for free and a small scale solution - OpenVPN - highly recommended.

Be certain to explain to company management that VPNs don't make you secure. Security needs to be layered from mandatory stong passwords, to active antivirus scanners, to software firewalls, to NAT routing and proxies. Lots of other things - turn off javascript unless needed (be selective).

Good luck!

-> Check third Paragraph

It's seamless as in you don't even pause you just connect to the faster connection automatically, or cheaper, really depending on how you configure. But the key is that it's quick enough to keep even a Voice session up an running.

It's not nessecarily T-Mobile's WiFi, well it might be in this deployment, but the biggest reason for the lethargic roll-out in the US is the mighty Carrier's don't know how to bill you for the call, the billing piece is not yet configured and everyone is still fighting for your $Texas$

It has been used by NASA providing WLAN coverage for press to file stories during the recent shuttle launch, Marshalltown, Iowa deployed it, University of Arkansas deployed it, an entire city in Taiwan is deploying it

Unlike Cisco it is not bolted on through buying a company, rather developed from the ground up and it does not work in a star config, rather a true mesh as the name implies...

I'm sick of seeing Cisco get coverage here when they deliver late, with inferior products

You can buy a small bts (base station transceiver) but that is only half of it. A bts is not designed to connect to the pstn. You would still need a GSM switch. Nortel makes what they call an e-cell which is meant for small buildings or inside malls. It costs $30,000. You are probably better off using WiFi or something like this.

Certain once-large organizations have shed a lot of (and will soon shed all ) folks around here, and others are threatening to do the same. Not surprising, since RTP has been so telecom-centric, and unlike Silicon Valley, concentrates its employment base in a handful of large companies (vs. gajillions of startups).

The upshot is that there are a lot of unemployed techies around here who need re-training. Enter TechEngage. The proposition is simple: if you're unemployed, you get to attend a certain number of classes for free (or close to it), and in return, you donate 40 hours of your time to the cause.

I really wish the public sector would wake up to this effort. Oh, sorry, that would be socialist. Can't have that. Unless of course you're an unemployed textile worker in the western part of NC, without even a high-school diploma. Then our state legislature bends over for you, even though you could never contribute as much to the tax base once employed (grumble)..

Nortel has some really good product: here, their VOIP handsets/desktop phones and software-based-voip-phones are *very* cool... coupled with a 802.11x AP, it is VERY COOL. Ipaq + 802.11x CF Nic + Nortel Software == wirless phone in your office.

Yeah, here in Europe (Belfast -N.Ireland to be exact) things have been screwy too. I graduated in 2000, and went straight into work for Nortel Networks ,as a telecoms engineer. I lasted about 6 months before they could no longer afford me! Then I went to work for a smaller local telecoms company called AePONA , but times became hard for them too: made redundant just before xmas (boo!). I've decided to leave telecoms behind me, and am now working for a bespoke software company Avalanch , and life is grand! .... so far. -=danny=-

I was at a Pub one evening (I live in Montreal) and I happened to meet their sales manager... ms. Jen Goldfinch. Although I had seen the Hyperchip building on many occasions, I had never inquired as to what they do. After meeting this woman, I was given the impression that their routers are actually in use by some of the big players in the digital pipelines game. She was actually pretty clear on that, although I can't seem to find any exact information concerning their customers on their website. Perhaps some questions to nortel, and qwest folks might clear this up. The only thing that make me dubious about her claim of widespread adoption, would be that if their products are so much "better" (for the lack of a better word) than the competitions, then why is abilene using cisco products? Unfortunately I don't have that kind of time on my hands.

I am sitting not more than 3 feet from a Nortel internet phone. It works just like a regular phone as far as I'm concerned, except it shares my lan with my PC through a 3 port 10/100 switch. here's the product page.

With that kind of grouping of Linux Power, there's an awful lot of Linux interest in this town - hence, a great deal of interest in running a Symposium (Thanks AH!)... if you want a symposium in your neighborhood, start one up! Can't guarantee that Alan Cox will make it (I got to sit next to him and Telsa during Miguel's keynote speech... I think I absorbed some kernel-kung-fu via osmosis)... but you never know what might come of your attempt. Maybe a few attendees will create the next great OpenSource project...

What's cool about this, is they put 40Gbps on a single carrier on a fiber. This means that, eventually, they can stack a bunch of 40Gbps carriers, on slightly different laser frequencies, in the same fiber to carry [1,2,4,8?]Tbps.

Commercial systems with the capacity to carry over a Terabit-per-second of data over a single fiber are already commercially available (and actually shipping) from companies like Ciena and probably Nortel. Lucent says they have equipment in the lab that is faster, but they're a bit like Microsoft in terms of making press releases long before they have working products, to inspire FUD in their competitor's potential customers... :^)

Nortel was working on this a while back but I think they've largely abandoned the effort. I remember reading a white paper on it. I think they called it "Data Transmission Over Conditioned Power Lines". The original URL was http://www.nortel.com/powerline/ although I can't seem to hit it now.
