Nerd Knobs and Open Source in Network Software

Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer... more

China and Taiwan to Lead the Development of 4G

China missed out on playing a leadership role in the development of 3G and as we predicted at that time, China would most certainly start looking at 4G for a major involvement in developing the technologies for it. more

OIAC Report: Views on Economic Impacts of Open Internet, Mobile Ecosystems, Specialized Services

Having been a member of the Committee for this past year, I'm pleased to share that the US Federal Communications Commission (FCC) "Open Internet Advisory Committee" has published its first annual report... The report is weighty - 98pp if you kill trees to print it. The OIAC was established as part of the US FCC Open Internet activity and Open Internet Report and Order from 2010. The FCC appointed expert committee members from a broad range of commercial, academic, and not-for-profit organizations. more

Cyber and Telecommunications Defence One of the Fastest Growing Industries in the World

In the past five years, cyber and telecommunications defence has left its niche market to become one of the fastest growing industries in the world. In 2011, governments, industry and ordinary computer users spent roughly £65 billion shoring up their computer networks, a figure that is predicted to double within five years. more

The Value of Community Broadband

There are many voices calling for increased initiatives by municipalities to build and operate broadband internet infrastructure as a public utility, but until this week, very little in the way of economic analysis to fully examine whether the benefits justify the costs. A paper released this week finds that local efforts produce small economic benefits, but cause a notable increase in the size of local government. more

The Google Factor in the Obama Broadband Speech

Every time Google becomes involved in telecommunications it gets international media coverage; and every single time the same question is raised -- why does Google become involved in telecoms infrastructure, plus the underlying issue of it becoming a telecoms operator. This time the question is -- why does Google want to become involved in mobile telecoms and how is it going to compete with the other operators? more

Just One Bit

I'm never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the IETF. Is this an example of a severe overload of obsessive-compulsive behaviour? Or does this single bit represent a major point of design principle... more

The Early History of Usenet, Part VIII: The Great Renaming

The Great Renaming was a significant event in Usenet history since it involved issues of technology, money, and governance. From a personal perspective -- and remember that this series of blog posts is purely my recollections – it also marked the end of my "official" involvement in "running" Usenet. I put "running" in quotation marks in the previous sentence because of the difficulty of actually controlling a non-hierarchical, distributed system with no built-in, authenticated control mechanisms. more

Looking Back on 2012: What’s in our Rearview Mirror?

Well, 2012 is almost over, and we can now reflect on the major events that hit our industry this year. If I had to choose the top three trends from the past 12 months, they would have to be: 1. Over-the-top (OTT) services; 2. IPv6 deployments (finally!); 3. TR-069 adoption. Let's examine each of these in more detail. more

Telecoms Infrastructure As a Service

More than a decade ago we predicted that the telecoms industry would be transformed, driven by its own innovations and technological developments. As a result we indicated that in many situations the telecommunications infrastructure would be offered as a service by hardware providers. We also predicted that this would open the way for a better sharing of the infrastructure. more

CIDR in Networking: Improved IP Routing Efficiency

CIDR (Classless Inter-Domain Routing) is a routing system in which network engineers can distribute IP addresses based on the size of their specific network. This is more efficient than the previous system, which assigned IP addresses depending on whether the size of a network fits into one of only three sizes: Class A, Class B, and Class C. more

In a Networked World Knowing the Right Time Is Essential but How Accurate Are the Computer Clocks?

Computers have always had clocks. Well maybe not clocks as you might think, but digital computers have always had oscillators, and if you hook the oscillator to a simple counter then you have a clock. The clock is not just there to tell the time, although it can do that, nor is it there just to record the time when data files are created or modified, though it does that too. Knowing the time is important to many functions, and one of those is security. more

Defending the Network Several Times Over

Modern networks can be attacked in a variety of ways, meaning that companies need different types of protection. This article explains some of the risks involved, and provides some easy ways to deal with them. more

Botnet Metrics and Calibration

As ISP's continue to spin up their anti-botnet defenses and begin taking a more active role in dealing with the botnet menace, more and more interested parties are looking for statistics that help define both the scale of the threat and the success of the various tactics being deployed... To overcome this problem there are several initiatives trying to grapple with this problem at the moment.. Obviously, if every ISP was using the same detection technology, in the same way, at the same time, it wouldn't be such a difficult task. Unfortunately, that's not the case. more

Green Revolving Funds Can Help Fund Costs of Cloud Computing and R&E Networking

There have been some interesting new developments in university Green Revolving Funds (GRF) that I believe could be a significant revenue opportunity for cloud suppliers and R&E networks. In this age of severe financial constraints and cutbacks for universities, new revenue models are needed to sustain advanced cyber-infrastructure in support of research and education. more
