There’s been a lot of talk in the news lately about the “Network Neutrality” principle. As usual with anything in politics, the term means different things to different people. So I’ll define it here: the most common aspect of the principle is that networks (such as your friendly neighborhood internet provider) should provide unfettered, unfiltered access to the Internet. I agree with this principle. Once providers get into the business of limiting content, we don’t have an Internet – we’d have multiple versions of the Internet and free speech would be at risk. However, there are circumstances where a provider must manage traffic on their networks. All Internet access is shared. The Internet is inexpensive because all of us are sharing its infrastructure, and this works because not all of us are using the Internet at the same time. Larger providers may see 60 to 1 effective oversubscription; i.e. out… read more →
There’s been a lot of talk, and frankly fear-mongering, in the press about the current recession. It’s “the biggest financial disaster since the 30s” by some accounts, although it’s hard to reconcile that with inconsistent economic data (such as the fact of contuining GDP growth through the first half of 2008). With all the comparisons to the Great Depression, it’s worthwhile to discuss briefly my take on it. I am an incessant optimist, but I just have to respond to all the negativity. First off, recessions are a normal part of the business cycle. The business cycle is: make investment, operate business, depreciate capital, close business. You invest capital in order to be able to run a business, produce products, be more efficient. At some point, that capital must be depreciated, because the factory machines are worn out and need replaced, or the product is no longer relevant in the… read more →
Finally, the day came! Our conduit was ready. The fiber was here. All that remained was putting it in the ground. How do you do that? What all is involved when you see those guys in the orange vests and hard-hats in the middle of the street, crawling in and out of manholes? A lot, it turns out. The first step is “pulling” a permit with the city. To get a permit, you need construction experience, a performance bond, and a traffic plan. The traffic plan details where work is to be done, how you are going to block the street, and how you will re-route traffic around the blockage. At least in Denver, it seems pretty straightforward. On the day, the sign company brought tons of orange road pylons, and road-signs announcing the blockage. It was pretty thrilling, the idea of being responsible for blocking a street and re-routing… read more →
Using Ethernet to deliver WAN (Wide-Area Network) services such as Internet access, point-to-point multi-site networking, can greatly simplify network design, improve reliability, and reduce costs.
Hi all, I have been wanting for some time to improve communication with our customers – and in addition to trying to get newsletters published more regularly, thought that I would experiment with blogging as a way to get timely information out to you without necessarily filling your mailboxes with stuff you might not want to read. So, welcome! My first series of posts will be in regards to our first-ever underground fiber build. Jawaid Bazyar, President
So, you are crazy enough to want to build your very own metropolitan fiber-optic network. You are in good company – I am crazy enough to want to do it. I am also crazy enough to want to share the experience, and tell you how to do it. I believe that in sharing what I learn I will ultimately learn more than if I tried to keep this all a secret. I am going to share this, also because I think it will make good reading for tech-heads like myself. This isn’t rocket science, but it’s also far enough removed from day-to-day IT stuff that the solutions to some of the problems involved are not obvious! That said, in I dive. The first step of our project is to build an “entrance facility”. This is basically a fiber cable penetrating into a Qwest Central Office – those are the buildings… read more →
