Mobile broadband: Why don’t you call anymore?

    On a recent train journey to London, I found myself shoe-horned into a fully booked quiet coach. When I pulled out my usual travelling companions – iPhone and Blackberry – I thought I would be greeted by looks of disdain or at the very least some ssshhhing. However, this wasn’t the case and when I looked around I began to see why.Read more

    Does the US need a Digital Champion?

    In recent weeks, the development of the United States’ broadband infrastructure has taken a few sharp body blows. First was the Google/Verizon net neutrality furore and now research results that show the rollout of universal broadband is not deemed a priority or even necessary by the majority of Americans.

    According to the Pew Internet Project’s latest research, at least 52% of Americans believe that President Obama’s $7.2 billion in stimulus funds should be spent on other areas rather than the country’s broadband infrastructure. This comes as somewhat of a shock, especially at a time when most of the world’s developed countries are striving to claim the bejewelled prize of a true networked nation.   Read more

    …waiting for the WARP drive

    While recent blog posts on low-latency networks were focused on speeds and feeds of data transport between two given locations the underlying physics were always considered as a constant that cannot be changed. It is widely accepted that fiber optic transport is the fastest and most efficient way to transfer information in networks and the speed of light seems to be the natural barrier here. To break this natural barrier, things like WARP drives or usage of wormholes could be the next alternative but unfortunately research has not reached a status yet that would make such things seem realistic (see NASA - Status of "Warp Drive"). But before we start thinking about speeds faster than speed of light we could actually still improve the speed we are using today for fiber optic transmission.Read more

    The green network: Still a pipe dream?

    In 2008 and 2009, green networking was a hot topic in the storage and enterprise space. It was impossible to attend an exhibition or conference without seeing a raft of roundtables, presentations and general hype about the topic. There were even some dedicated green networking shows. Although I have to confess that the only thing memorable about these events was the non-green nature of my carbon footprint to attend.

    In 2010, green networking appears to have lost some of its buzz. One need only review the agendas for some of the larger enterprise-focused shows to see this. Take IP Expo or 360IT as examples. Green has clearly been replaced by cloud. And while I agree that cloud computing certainly includes elements of green networking, I cannot help feel a little concerned that green networking appears to have disappeared as a critical topic of discussion.Read more

    Counting the cost of next-generation access

    On a recent trip from Munich to Meiningen, I set myself a challenge of counting the number of local exchanges and street cabinets that came into view. In my defense, my iPod was flat and there was little to listen to on the radio. Needless to say, this task proved a little more difficult than I expected. In fact, I lost count somewhere around 100.

    Still, I was amazed at the number of facilities that service providers needed to maintain. The cost when considered on a national scale is enormous. This was part of the reason I was travelling to Meiningen. I was visiting our Next-Generation Access (NGA) Solution center, designed to show the impact of eliminating active equipment between the Central Office (CO) and Customer Premise (CP) to some of our customers.Read more

    Is net neutrality even realistic?

    The NY Times has a great op-ed on "Net Neutrality" this week, which got me thinking… Is the expectation of total and complete internet neutrality realistic and do we even understand what that might entail?

    First, let's look at what net neutrality might actually be defined as.  Strangely, when discussing net neutrality, often examples of net non-neutrality are cited. These are typically cases where Internet Service Providers (ISP's) have blocked various applications or throttled the heavy bandwidth consumption from heavy users.  From my point of view, net neutrality is not just an ISP issue, concerning what they will allow or not allow, but a Carrier Ethernet issue as well.  A packet typically travels across dozens of networks owned by different companies from source to destination. Any one of these networks could decide to impede, limit, or throttle the packet depending upon a wide range of attributes, including where it originated from, the type of packet, the host application, etc.  On one hand, if every carrier in the world decided to start doing as it pleased with any packets traversing its network, the internet would cease to function as we know it today.  On the other hand, faced with a deluge of packets, carriers are being forced to at least set some guidelines, limits, and rules.Read more

    How much data is too much data?

    The explosion of data being generated and transported across the world’s networks is a topic that often consumes a great deal of time in the storage and enterprise community. I often find myself engaged in discussions on data transport using terms such as gigabytes, terabytes, petabytes and even zettabytes. However, there are times when these words are thrown around with alarming casualness and this was reinforced today when I came across the graphic below.

    I was amazed by some of the figures.Read more
