We all know that IPv6 will give us so many IPs we won’t have to use NAT or dynamic addressing, and we’ll still have enough IPs for every man, woman and child + dog until we colonize the entire solar system. But “lotsa IPs” is just one of the dozen possible benefits IPv6 brings to the table. Here’s a good two-part article called How Did IPv6 Come About, Anyway?

MPLS SOS?
Anyone who has fiddled with IP VPN or Cisco MPLS knows it’s a bizarre beast. No PVCs, the network’s magically fully-meshed, and you need special routers.
So how do you back up an IP VPN connection? Traditionally, if you got a, say, a frame relay T1, most places settle for an ADSL, ISDN dial-on-demand, a 56K dialup line, a fractional T1 or even a second T1, depending on how much bandwidth and functionality you needed in a backup situation. But these things won’t work out in VPNe La-La Land.
It’s simple: to back up an IP VPN connection, you use a second IP VPN connection. If you have an IP VPN T1, for instance, you can run a second VPN T1 or go for a cheaper IP VPN ADSL link. Keep in mind the ADSL link will have a lower MTTR, and will be less reliable.
Depending on your service provider, you will probably have three kinds of diversity. For the cheapest way, just have both your primary and auxiliary connection go to the same provider edge router. For a bit more added protection, you can have the two connections go to two separate PE routers. If you’re the belt-and-suspenders type of person, you can go all out and have these two connections go to two separate PE routers housed in to separate COs.
MS vs. my company
Just some brainstorms.
- We don’t eat our own dogfood. We push embedded wireless devices and Voice over IP, and yet we stick our people with cheap 4-year old cellphones and use a plain ol’ PBX to route calls.
- We don’t have a progressive technology plan. Half the organization uses WindowsNT. The other half uses Windows 2000. Some enjoy local administrator rights to their PCs, others don’t even get CD-ROM drives in their computers. Some are standardized on Outlook XP and IE6, some have Outlook 98 and IE5, and the rest of the company waddles on with Netscape Communicator 4.7. Office versions range from Office 95 to XP.
- We don’t stay current. Users are actually discouraged from using Windows Update. Some users are still using NT4 SP3 and Netscape 4.7. This caused many PCs to bite the dust when the Blaster worm made its rounds.
- We don’t maximize the potential of the tools we already have. Take how MS uses Outlook. If you are looking for someone, a receptionist can personally pull up their shared Outlook calendar and peruse their schedule. If you leave voicemail for someone, he/she can listen to it from their computers as a WAV file. Employees can check email any PC in the world with just a web browser. It’s not magic, it’s Outlook Web Access – a product Bell we currently sell as part of our Hosted Exchange business solution! Except even we don’t use it (see #1).
- Perhaps before we ask for more, we give some more. Imagine if we offered free snacks and beverages to their employees. Expensive, you say? But if a $1 can of Coke makes an employee work longer, harder and happier on any given day, wouldn’t you say it’s worth it?
- We make it hard for people to stay in touch. Salespeople typically carry around a cellphone *and* a pager, and play phone tag with their office phone. In London, we cannot even forward out office phones to our cellphones. We don’t use PrimeLine or SimRing. Most people don’t have their mobile numbers published in the employee directory. We lack a form of realtime communication – workers are not encouraged to use SMS or instant messaging. This translates to long lead times and mistakes – you leave an email or voicemail, and hope that the guy heard you right and calls you back before the end of the week.
- We don’t shout out own name loud enough. A building’s lobby should have a big colourful Sympatico High Speed Internet access kiosk and an ExpressVu driven TV set. Salespeople should be given the latest Mobility gizmos to give our products free public exposure. We should be giving out free Sympatico dialup CDs and QuickChange calling cards. Managed routers and other networking equipment should be given big, bright Bell Managed Solutions branded stickers, not scribbled-on tiny white Avery labels.

When UIs attack
Here’s a good example of how NOT to design the login UI of a web app. The name of this app has been changed to protect the innocent. :devious:
The login screen tries to be radical by placing the Clear button on the left of the screen, and the OK button on the right. To spice things up, the buttons are labelled in English and French, together. So instead of “OK”, you get wordy buttons saying “OK – Envoyer”.
After logging in, you get a useless dialog about when your last successful login was. Whee. You must click a graphic that says “OK” to get past this screen. (No more “Envoyer” silliness here!)
You are now given a screen with three options, only one of actual use to you: Ordering. Once clicked, you see another link, “ABC Viewer” (also the only option available).
After logging in, it should load the app right away. Everything else is redundant. And the
Five inches short of a…
James Randi often remarks that just because someone has an impressive professional title, it doesn’t mean he can’t be a freakin’ moron. The fact that mutual fund managers, CEOs, veterinarians and otherwise intelligent people would buy penis-enlargement pills off an anonymous spam email with no encryption, and no contact information.
In a way, these people have what they wanted – to be considered as big dicks.

Bon mots
Hold the freedom fries: I think a few modern-day American politicians should pick up this book, “112 Gripes about the French”, a FAQ for American GIs in post-WW2 France. It was published by the US government, to massage over misunderstandings and ill feelings the stationed soldiers felt for France.
Incredibly well-written retorts to common complaints, the book also offers this timeless advice: “Beware the people who do not criticize. Beware the country where criticism is verboten. Beware the country where men obey like sheep.”
Contivity confusion
This morning, I took and passed the certification exam for Nortel Networks Certified Design Specialist for Contivity VPN Extranet Switches (NNCDS – Contivity). So now I know a lot more about the Contivity than most mortal men.
The Contivity is actually a pretty neat product – it’s a router, it’s a stateful firewall, but most of all, it’s a VPN demarcation point. Simply put, it allows a remote user to access their corporate LAN via the public Internet in a completely secure fashion. Cisco PIX and Netscreen devices can do the same thing, but Contivitys are fairly inexpensive, high-performing, and easy to configure.
What was hard to figure was the bloody exam. First off, the Global Knowledge book and course I took was scarcely adequate. Sample questions, which they claimed were based on actual exam questions, did not even remotely resemble the exam in format, topic or difficulty. The samples were simple “gimmies”, like “Does the Contivity 100 support user tunnels? True/False?” (False, btw).
The real questions were scenario-based. They went like this: You are required to implement a 5000 tunnel solution. They have users dialling in from home, as well as branch offices. Which Contivity with which options would you recommend?”
Topics, such as IPX encapsulation, and the featureset of the Advanced Routing License, were not even covered.
The exam itself was fairly poorly designed. A lot of the questions boiled down to semantics. I feel sorry for the ESL crowd, they would have a helluva time figuring out these vague, obtuse questions. Here’s a good example.
Question: HQ has two Model Zs. They want remote users and their business partners to connect to them. What should the remote offices do? (“Remote offices”? I guess they mean both the remote users and business partners.)
- Model X, end to end (end to end of what?)
- Model X only for SOHO (Too bad if you don’t know what SOHO stands for. Also: are you referring to the “remote users”? Or the business partners? Both? If so, why the distinction?)
- Model X only for the remote offices (Only?! Isn’t this question only about the remote offices to begin with???)
In contrast, the Cisco exams are usually difficult and sometimes tries to trick you, but not by straining your knowledge of the English language.
Justice, CRTC style
Aliant, the incumbent telco, and Groupe Telecom, the competing telco, bid for two school contracts in St. John’s, Newfoundland. Aliant offers a price lower than GT. GT complains to the CRTC, charging anti-competitive pricing. CRTC agrees, orders Aliant to increase its price above GT’s. Customer looks at GT’s now relatively lower price, and switches to GT. GT crows about fair pricing to customers.
Now Aliant owns all the wiring (after all, they built them). GT now complaining to CRTC that the wholesale rates Aliant is charging are too high. Wants Aliant to now lower their prices.
